When Bats decide to move into your home or business, they can create a big problem in Scranton Pennsylvania. Advanced Wildllife Management are bat experts and have years of experience in the proper bat removal and control solutions. Bats can be a Health and Safety issue especially if they get into the interior of a home or business. Not all situations are bad though. Bats are vital to our environment, as they can consume several hundred mosquitoes in a single hour. Bat Guano is used commercially and is highly regarded as a fertilizer. But when Bats have taken residence in a attic, there is no good situation.

We are fully licensed and insured with years of experience and work hand in hand with state wildlife agencies and are state certified. Our bat removal step-by-step solutions will effectively solve bat problems permanently.


Human expansion and destruction of habitat have resulted in bats seeking alternative roost sites like roof voids (as small as 3/8 inch), attics, wells, buildings, and barns.


According to the Health Department, if a bat is is in your home, there is evidence that it is possible for the bat rabies virus to infect victims purely through airborne transmission, even if there was no direct contact with the bat. The biggest problems with the bats comes from their droppings (or guano), diseases, and parasites.



Conservation and Public Education
Despite their ecological value, bats are relentlessly and unjustifiably persecuted. Bats are often killed because they live near people who needlessly fear them. These actions emphasize the need to educate the public on the reasons for bat conservation and why it is important to use safe, nondestructive methods to alleviate conflicts between people and bats. General sources of information on bats include states? Cooperative Extension Services, universities, government environmental conservation and health departments, and Bat Conservation International (Austin, Texas). Except where control is necessary, bats should be appreciated from a distance ? and not disturbed.

Identification and Range
Bats, the only mammals that truly fly, belong to the order Chiroptera. Their ability to fly, their secretiveness, and their nocturnal habits have contributed to bat folklore, superstition, and fear. They are worldwide in distribution and include about 900 species, second in number only to Rodentia (the rodents) among the mammals.

Among the 40 species of bats found north of Mexico, only a few cause problems for humans (note that vampire bats are not found in the United States and Canada). Bats congregating in groups are called colonial bats; those that live a lone existence are known as solitary bats.

The colonial species most often encountered in and around human buildings in the United States are the little brown bat, (Myotis lucifugus), the big brown bat (Eptesicus fuscus), the Mexican free-tailed bat (Tadarida brasiliensis,), the pallid bat (Antrozous pallidus), the Yuma myotis (Myotis yumanensis), and the evening bat (Nycticeius humeralis).

Solitary bats typically roost in tree foliage or under bark, but occasionally are found associated with buildings, some only as transients during migration. These include Keen?s bat (Myotis keenii), the red bat (Lasiurus borealis), the silver-haired bat (Lasionycteris noctivagans), and the hoary bat (Lasiurus cinereus). Excellent illustrations of all bats discussed herein can be found in Barbour and Davis (1979), Tuttle (1988), Geluso et al. (1987), and Harvey (1986).

Several species of bats have been included here, with significant interspecific differences that need to be clarified if well-planned, comprehensive management strategies are to be developed. Any problems caused by bats are limited to species distribution; thus animal damage control personnel need not be concerned with every species.

Colonial and solitary bats have obvious differences that serve to separate the species into groups. Much of the descriptive material that follows is adapted from Barbour and Davis (1979).

Colonial Bats

Little brown bat (Myotis lucifugus)


forearm ? 1.34 to 1.61 inches (3.4 to 4.1 cm)
wingspan ? 9.02 to 10.59 inches (22.9 to 26.9 cm)
ears ? 0.55 to 0.63 inches (1.4 to 1.6 cm)
foot ? approximately 0.39 inches (1.0 cm); long hairs on toes extend beyond claws.

Pale tan through reddish brown to dark brown, depending on geographic location. The species is a rich dark brown in the eastern United States and most of the west coast. Fur is glossy and sleek.

Confusion may occur with a few other ?house? bat species. In the East, it may be confused with Keen?s bat (M. keenii), which has longer ears [0.69 to 0.75 inches (1.7 to 1.9 cm)] and a longer, more pointed tragus (the appendage at the base of the ear). In the West, it resembles the Yuma myotis (M. yumanensis), which has dull fur and is usually smaller. However, the Yuma myotis and little brown may be indistinguishable in some parts of the northwestern United States where they may hybridize.

This is one of the most common bats found in and near buildings, often located near a body of water where they forage for insect prey. Summer colonies are very gregarious, commonly roosting in dark, hot attics and associated roof spaces where maternity colonies may include hundreds to a few thousand individuals. Colonies may also form beneath shingles and siding, in tree hollows, beneath bridges, and in caves. Litter size is 1 in the Northeast; twins occasionally occur in some other areas. The roost is often shared with the big brown bat (E. fuscus) though the latter is less tolerant of high temperatures; M. keenii may also share the same site. Separate groups of males tend to be smaller and choose cooler roosts within attics, behind shutters, under tree bark, in rock crevices, and within caves.

In the winter, little brown bats in the eastern part of their range abandon buildings to hibernate in caves and mines. Such hibernacula may be near summer roosts or up to a few hundred miles (km) away. Little is known of the winter habits of M. lucifugus in the western United States.

The life span of little brown bats has been established to be as great as 31 years. The average life expectancy, however, is probably limited to only a few years.

Big brown bat (Eptesicus fuscus)

forearm ? 1.65 to 2.01 inches (4.2 to 5.1 cm)
wingspan ? 12.80 to 13.78 inches (32.5 to 35.0 cm)
ears ? with rounded tragus

From reddish brown, copper colored, to a dark brown depending on geographic location. This is a large bat without distinctive markings.

Confusion may occur with the evening bat (Nycticeius humeralis) though the latter is much smaller.

This hardy, rather sedentary species appears to favor buildings for roosting. Summer maternity colonies may include a dozen or so and up to a few hundred individuals, roosting behind chimneys, in enclosed eaves, in hollow walls, attics, barns, and behind shutters and unused sliding doors. They also form colonies in rock crevices, beneath bridges, in hollow trees, and under loose bark. Litter size is 2 in the East to the Great Plains; from the Rockies westward 1 young is born.

E. fuscus frequently shares roosts with M. lucifugus in the East, and with M. yumanensis, Taderida, and Antrozous in the West. Males typically roost in smaller groups or alone during the summer.

The big brown bat is one of the most widely distributed of bats in the United States and is probably familiar to more people than any other species. This is partially due to its large, easy-to-observe size, but also to its ability to overwinter in buildings (attics, wall spaces, and basements). Its close proximity to humans, coupled with its tendency to move about when temperature shifts occur, often brings this bat into human living quarters and basements in summer and winter. Big browns also hibernate in caves, mines, storm sewers, burial vaults, and other underground harborage. While E. fuscus will apparently travel as far as 150 miles (241 km) to hibernacula, the winter quarters of the bulk of this species are largely unknown.

Big brown bats may live as long as 18 years.

Mexican free-tailed bat (Tadarida brasiliensis)

forearm ? 1.42 to 1.81 inches (3.6 to 4.6 cm)
wingspan ? 11.42 to 12.80 inches (29.0 to 32.5 cm); long narrow wings
tail (interfemoral) membrane ? does not enclose the lower one-third to one-half of the tail, hence the name free-tailed
foot ? long, stiff hairs as long as the foot protrude from the toes.

Dark brown or dark gray. Fur of some individuals may have been bleached to a pale brown due to ammonia fumes from urine and decomposing guano.

Confusion is not likely to occur with other species that commonly inhabit human buildings.

T. brasiliensis forms the largest colonies of any warm-blooded animal, establishing sizable colonies in buildings, particularly on the West Coast and in the Gulf states from Texas east. Hundreds to thousands may be found in buildings or under bridges. It is primarily a cave bat in Arizona, New Mexico, Oklahoma, and Texas; buildings are used as temporary roosts during migrations. Litter size is 1.

Taderida often share roosts with other species. In the West, for example, they may be found in buildings with A. pallidus, M. yumanensis, and E. fuscus. Some males are always present in the large maternity colonies, but they tend to segregate in separate caves.

A few Taderida may overwinter in buildings as far north as South Carolina in the East and Oregon in the West. Most of this species migrate hundreds of miles to warmer climes (largely to Mexico) for the winter.

Pallid bat (Antrozous pallidus)

forearm ? 1.89 to 2.36 inches (4.8 to 6.0 cm)
wingspan ? 14.17 to 15.35 inches (36.0 to 39.0 cm)
ears ? large; widely separated and more than half as broad as long. The ears are nearly half as long as the combined length of the bat?s head and body.
eyes ? large

pale, upper parts are light yellow, the hairs tipped with brown or gray. Underparts are pale creamy, almost white. This large, light-colored bat is relatively easy to recognize.

Confusion with other species that commonly inhabit human buildings is not likely to occur.

Maternity colony size ranges from about 12 to 100 individuals. Roost sites include buildings, bridges, and rock crevices; less frequently, tree cavities, caves, and mines. Litter size is most commonly 2. The roost is frequently shared with T. brasiliensis and E. fuscus in the West. While groups of males tend to segregate during the nursery period (sometimes in the same building), other males are found within the maternity colony.

An interesting feature of pallid bats is that they fly close to the ground, may hover, and take most prey on the ground, not in flight. Prey includes crickets, grasshoppers, beetles, and scorpions. They will also forage among tree foliage.

Pallid bats are not known to make long migrations, though little is known of their winter habits.

Yuma myotis (Myotis yumanensis)

forearm ? 1.26 to 1.50 inches (3.2 to 3.8 cm)
wingspan ? about 9.25 inches (23.5 cm)
ears ? 0.55 to 0.59 inches (1.4 to 1.5 cm)
foot ? 0.39 inches (1.0 cm)

Light tan to dark brown; underside is whitish to buffy.

Confusion may occur in the West with M. lucifugus, though the latter tends to have longer, glossier fur, and is larger. In the Northwest, hybridization occurs with M. lucifugus, making the species indistinguishable.

Maternity colonies, up to several thousand individuals, form in the summer in attics, belfries, under bridges, and in caves and mines. Litter size is 1. Males typically segregate during the nursery period and roost as solitary individuals in buildings and other suitable harborage.

M. yumanensis is more closely associated with water than is any other North American bat species. Nearly all roosts have open water nearby. This species is not as tolerant as M. lucifugus of high roost temperatures and will move to cooler niches within a building when temperatures rise much above 100°F (37.8°C).

M. yumanensis abandons maternity colonies in the fall, but its winter habitat is not known.

Evening bat (Nycticeius humeralis)

forearm ? 1.30 to 1.54 inches (3.3 to 3.9 cm)
wingspan ? 10.24 to 11.02 inches (26.0 to 28.0 cm)
ears ? with short, curved, and rounded tragus

Confusion may occur with the big brown bat (E. fuscus), which can be readily distinguished by its larger size. It bears some resemblance to the somewhat smaller little brown bat (M. lucifugus) but can be identified by its characteristic blunt tragus.

Medium brown with some variation to yellow-brown in subtropical Florida. No distinctive markings.

Summer maternity colonies in buildings may consist of hundreds of individuals. Litter size is usually 2. Colonies also form in tree cavities and under loose tree bark. In the Southeast, T. brasiliensis commonly inhabits the same building with N. humeralis. This is one of the most common bats in towns throughout the southern coastal states. Very little is known about this species, and virtually nothing is known of its winter habitat except that it almost never enters caves.

Solitary Bats

Keen?s bat (Myotis keenii)

forearm ? 1.26 to 1.54 inches (3.2 to 3.9 cm)
wingspan ? 8.98 to 10.16 inches (22.8 to 25.8 cm)
ears ? 0.67 to 0.75 inches (1.7 to 1.9 cm); with a long, narrow, pointed tragus

Brown, but not glossy; somewhat paler in the East.

Confusion may occur with M. lucifugus, which has glossy fur, shorter ears, and does not have the long, pointed tragus.

Excluding small maternity colonies (up to 30 individuals are on record), M. keenii are generally found singly in the East. Roosting sites include: behind shutters, under wooden shingles, sheltered entryways of buildings, in roof spaces, in barns, and beneath tree bark. In the West, this bat is known as a solitary species, roosting in tree cavities and cliff crevices. Litter size is probably 1. The roost is sometimes shared with M. lucifugus. The sexes probably segregate during the nursery period. In winter, these bats hibernate in caves and mines.

Red Bat (Lasiurus borealis)

forearm ? 1.38 to 1.77 inches (3.5 to 4.5 cm)
wingspan ? 11.42 to 13.07 inches (29.0 to 33.2 cm); long, pointed wings
ears ? short rounded
tail membrane ? heavily furred on upper surface, with a distinctive long tail.

Bright orange to yellow-brown; usually with a distinctive white mark on the shoulders.

Confusion may occur with the hoary bat (L. cinereus), which is frosted-gray in appearance and larger.

Red bats live solitary lives, coming together only to mate and migrate. Few people are familiar with this species. They typically spend summer days hidden in the foliage of deciduous trees. The number ofyoung ranges from 1 to 4, averaging 2.3.

These bats often chase insects that are attracted to lights, such as street lamps. It is this behavior that most likely brings them in close proximity to people.

L. borealis is well-adapted for surviving drastic temperature fluctuations; it does not hibernate in caves, but apparently in trees. Some migrate long distances. During migration, red bats have been known to land on high-rise buildings and on ships at sea.

Silver-haired bat (Lasionycteris noctivagans)

forearm ? 1.46 to 1.73 inches (3.7 to 4.4 cm)
wingspan ? 10.63 to 12.20 inches (27.0 to 31.0 cm)
ears ? short, rounded, hairless
tail membrane ? upper surface is sparsely furred on the anterior one-half.

Usually black with silver-tipped fur; some individuals with dark brown, yellowish-tipped fur.

Confusion sometimes occurs with the larger hoary bat (Lasiurus cinereus), which has patches of hair on the ears and wings, heavy fur on the entire upper surface of the tail membrane, and has a distinctive throat ?collar.?

The silver-haired bat roosts in a wide variety of harborages. A typical roost might be behind loose tree bark; other sites include tree hollows and bird nests. This species is solitary except when with young. Additionally, there are unconfirmed reports that it is sometimes colonial (Dalquest and Walton 1970) and may roost in and on buildings. The litter size is 2. The sexes segregate through much of the summer range.

L. noctivagans hibernates in tree crevices, under loose bark, in buildings (including churches, sky scrapers, and wharf houses), hulls of ships, rock crevices, silica mines, and non-limestone caves. It also may migrate, during which time it is encountered in buildings (they favor open sheds, garages, and outbuildings rather than enclosed attics), in lumber piles, and on ships at sea.

Hoary bat (Lasiurus cinereus)

forearm ? 1.81 to 2.28 inches (4.6 to 5.8 cm)
wingspan ? 14.96 to 16.14 inches (38.0 to 41.0 cm)
ears ? relatively short, rounded, edged with black, and with fur
tail membrane ? completely furred on upper surface

Dark, but many hairs are tipped in white, giving it a frosted appearance. This bat also has a yellowish or orangish throat ?collar.?

Confusion may sometimes occur with the much smaller silver-haired bat (Lasionycteris noctivagans), which lacks the fur patches and markings on the ears, markings on the throat, and has a tail membrane that is only lightly furred on the upper surface.

Hoary bats generally spend summer days concealed in tree foliage (often in evergreens), rarely enter houses, and are not commonly encountered by people. L. cinereus at their day roosts are usually solitary except when with young. The litter size is 2. The sexes segregate through most of the summer range.

This is one of the largest bats in North America, a powerful flier, and an accomplished migrant. Records indicate that some L. cinereus may hibernate in northern parts of their range.

General Biology, Reproduction, and Behavior

Most North American bats emit high frequency sounds (ultrasound) inaudible to humans and similar to sonar, in order to avoid obstacles, locate and capture insect prey, and to communicate. Bats also emit audible sounds that may be used for communication between them.

Bats generally mate in the fall and winter, but the female retains the sperm in the uterus until spring, when ovulation and fertilization take place. Pregnant females may congregate in maternity colonies in buildings, behind chimneys, beneath bridges, in tree hollows, caves, mines, or other dark retreats. No nests are built. Births typically occur from May through July. Young bats grow rapidly and are able to fly within 3 weeks. Weaning occurs in July and August, after which the nursery colonies disperse.

Bats prepare for winter around the time of the first frost. Some species migrate relatively short distances, whereas certain populations of the Mexican free-tailed bat may migrate up to 1,000 miles (1,600 km). Bats in the northern United States and Canada may hibernate from September through May. Hibernation for the same species in the southern part of their range may be shorter or even sporadic. Some may fly during warm winter spells (as big brown bats may in the northeastern part of the United States). Bats often live more than 10 years.

In response to a variety of human activities, direct and indirect, several bat species in the United States have declined in number during the past few decades. Chemical pesticides (particularly the use of persistent and bioaccumulating organic pesticides) have decreased the insect supply, and contaminated insects ingested by bats have reduced bat populations. Many bats die when people disturb summer maternity roosts and winter hibernacula. Vandals and other irresponsible individuals may deliberately kill bats in caves and other roosts. Even the activities of speleologists or biologists may unintentionally disturb hibernating bats, which depletes fat reserves needed for hibernation.

Modification and destruction of roost sites has also decreased bat numbers. Sealing and flooding of mineshafts and caves and general quarrying operations may inadvertently ruin bat harborages. Forestry practices have reduced the number of hollow trees available. Some of the elimination of natural bat habitat may contribute to bats roosting in buildings.

Bat Presence
Bats often fly about swimming pools, from which they drink or catch insects. White light (with an ultraviolet component), commonly used for porch lights, building illumination, street and parking-lot lights, may attract flying insects, which in turn attract bats. Unfortunately, the mere presence of a bat outdoors is sometimes beyond the tolerance of some uninformed people. Information is a good remedy for such situations.

Bats commonly enter buildings through openings associated with the roof edge and valleys, eaves, apex of the gable, chimney, attic or roof vent, dormers, and siding.

Other openings may be found under loose-fitting doors, around windows, gaps around various conduits (wiring, plumbing, air conditioning) that pass through walls, and through utility vents.

Bats are able to squeeze through narrow slits and cracks. For purposes of bat management, one should pay attention to any gap of approximately 1/4 x 1 1/2 inches (0.6 x 3.8 cm) or a hole 5/8 x 7/8 inch (1.6 x 2.2 cm). Such openings must be considered potential entries for at least the smaller species, such as the little brown bat. The smaller species require an opening no wider than 3/8 inch (0.95 cm), that is, a hole the diameter of a US 10-cent coin (Greenhall 1982). Openings of these dimensions are not uncommon in older wood frame structures where boards have shrunk, warped, or otherwise become loosened.

The discovery of one or two bats in a house is a frequent problem. In the Northeast, big brown bats probably account for most sudden appearances. Common in urban areas, they often enter homes through open windows or unscreened fireplaces. If unused chimneys are selected for summer roosts, bats may fall or crawl through the open damper into the house. Sometimes bats may appear in a room, then disappear by crawling under a door to another room, hallway, or closet. They may also disappear behind curtains, wall hangings, bookcases, under beds, into waste baskets, and so forth. Locating and removing individual bats from living quarters can be laborious but is important. If all else fails, wait until dusk when the bat may appear once again as it attempts to find an exit. Since big brown bats may hibernate in the cooler recesses of heated buildings, they may suddenly appear (flying indoors or outdoors) in midwinter during a warm spell or a cold snap as they move about to adjust to the temperature shift.

Food Habits
Bats in North America are virtually all insectivorous, feeding on a variety of flying insects (exceptions among house bats were noted previously). Many of the insects are harmful to humans. While there must be some limitations based on such factors as bats? body size, flight capabilities, and jaw opening, insectivorous bats apparently consume a wide range of prey (Barbour and Davis 1979). The little brown bat?s diet includes mayflies, midges, mosquitoes, caddis flies, moths, and beetles. It can consume insects equal to one-third of its body weight in 1/2 hour of foraging. The big brown bat may fill its stomach in about 1 hour (roughly 0.1 ounce per hour [2.7 g/hr]) with prey including beetles, moths, flying ants, true bugs, mayflies, caddis flies, and other insects. The nightly consumption of insects by a colony of bats can be extremely large.

Damage and Damage Identification

Roosting Sites
Bats use roosting niches that are indoors (human dwellings, outbuildings, livestock quarters, warehouses), semi-enclosed (loading docks, entrance foyers), partially sheltered (porches, carports, pavilions, highway underpasses, bridges), and open structural areas (window shutters, signs). Once there, active bats in and on buildings can have several economic and aesthetic effects, often intertwined with public health issues (Frantz, 1988). Unusual roosting areas include wells, sewers, and graveyard crypts. Before considering control measures, verify that bats are actually the cause of the problem.

Rub Marks
Surface areas on walls, under loose woodwork, between bricks and around other bat entryways often have a smooth, polished appearance. The stained area is slightly sticky, may contain a few bat hairs, and is yellow-brown to blackish brown in color. The smooth gloss of these rub marks is due to oils from fur and other bodily secretions mixed with dust, deposited there as many animals pass repeatedly for a long period over the same surface. Openings marked in this way have been used heavily by bats.

Disturbing sounds may be heard from vocalizations and grooming, scratching, crawling, or climbing in attics, under eaves, behind walls, and between floors. Bats become particularly noisy on hot days in attics, before leaving the roost at dusk, and upon returning at dawn. Note that rustling sounds in chimneys may be caused by birds or raccoons and scratching and thumping sounds in attics and behind walls may indicate rats, mice, or squirrels.

Guano and Urine
Fecal pellets indicate the presence of animals and are found on attic floors, in wall recesses, and outside the house at its base. Fecal pellets along and inside walls may indicate the presence of mice, rats, or even roaches. Since most house bats north of Mexico are insectivorous, their droppings are easily distinguished from those of small rodents. Bat droppings tend to be segmented, elongated, and friable. When crushed, they become powdery and reveal shiny bits of undigested insect remains. In contrast, mice and rat droppings tend to taper, are unsegmented, are harder and more fibrous, and do not become powdery when crushed (unless extremely aged).

The droppings of some birds and lizards may occasionally be found along with those of bats. However, bat droppings never contain the white chalky material characteristic of the feces of these other animals.

Bat excrement produces an unpleasant odor as it decomposes in attics, wall spaces, and other voids. The pungent, musty, acrid odor can often be detected from outside a building containing a large or long-term colony. Similar odor problems occur when animals die in inaccessible locations. The odor also attracts arthropods which may later invade other areas of a building.

Bat guano may provide a growth medium for microorganisms, some of which are pathogenic (histoplasmosis, for example) to humans. Guano accumulations may fill spaces between walls, floors, and ceilings. It may create a safety hazard on floors, steps, and ladders, and may even collapse ceilings. Accumulations also result in the staining of ceilings, soffits, and siding, producing unsightly and unsanitary conditions.

Bats also urinate and defecate in flight, causing multiple spotting and staining on sides of buildings, windows, patio furniture, automobiles, and other objects at and near entry/exit holes or beneath roosts. Bat excrement may also contaminate stored food, commercial products, and work surfaces.

Bat urine readily crystallizes at room temperature. In warm conditions under roofs exposed to sun and on chimney walls, the urine evaporates so quickly that it crystallizes in great accumulations. Boards and beams saturated with urine acquire a whitish powderlike coating. With large numbers of bats, thick and hard stalactites and stalagmites of crystallized bat urine are occasionally formed.

Although the fresh urine of a single bat is relatively odorless, that of any moderate-sized colony is obvious, and the odor increases during damp weather. Over a long period of time urine may cause mild wood deterioration (Frantz and Trimarchi 1984). As the urine saturates the surfaces of dry wood beams and crystallizes, the wood fibers expand and separate. These fibers then are torn loose by the bats crawling over such surfaces, resulting in wood fibers being mixed with guano accumulations underneath.

The close proximity of bat roosts to human living quarters can result in excreta, animal dander, fragments of arthropods, and various microorganisms entering air ducts as well as falling onto the unfortunate residents below. Such contaminants can result in airborne particles of public health significance (Frantz 1988).

Ectoparasites and other Arthropods
Several arthropods (fungivores, detritivores, predators, and bat ectoparasites) are often associated with colonies of bats in buildings. Their diversity depends on the number of bats, age and quantity of excreta deposits, and season.Arthropods such as dermestid beetles (Attagenus megatoma) contribute to the decomposition of guano and insect remnants, but may also become a pest of stored goods and/or a nuisance within the living quarters. Cockroaches (for example, Blatta orientalis) attracted to guano may invade other parts of a building. Bat bugs (Cimex spp.) are sometimes found crawling on the surface of beams or around holes leading to secluded recesses used by bats. Bat ectoparasites (ticks, mites, fleas, and bugs) rarely attack humans or pets and quickly die in the absence of bats. Ectoparasites may become a nuisance, however, following exclusion of large numbers of bats from a well-established roost site. Area fumigation with a total release pyrethrum based aerosol may be an appropriate solution for arthropod knockdown within an enclosed space, but only after bats have departed. For long-term arthropod control, lightly dust appropriate surfaces (affected attic beams, soffits) with boric acid powder or diatomaceous earth; carefully read all product labels before using any pesticide. Note that neither rabies nor Lyme disease is transmitted by any arthropods associated with bats.

Public Health Issues

General Epidemiology Bats are distinct from most vertebrate pests that inhabit human dwellings because of the potential for transmitting rabies ? a viral infection of mammals that is usually transmitted via the bite of an infected animal. Rabies does not respond to antibiotic therapy and is nearly always fatal once symptoms occur. However, because of the long incubation period (from 2 weeks to many months), prompt vaccination following exposure can prevent the disease in humans. Dogs, cats, and livestock also can be protected by periodic vaccinations. Bats are not asymptomatic carriers of rabies. After an incubation period of 2 weeks to 6 months, they become ill with the disease for as long as 10 days. During this latter period, a rabid bat?s behavior is generally not normal?it may be found active during the daytime or on the ground incapable of flying. Most human exposures are the result of accidental or careless handling of grounded bats. Even less frequently, bats in this stage of illness may be involved in unprovoked attacks on people or pets (Brass, pers. commun.; Trimarchi et al. 1979). It is during this stage that the rabid bat is capable of transmitting the disease by biting another mammal. As the disease progresses the bat becomes increasingly paralyzed and dies as a result of the infection. The virus in the carcass is reported to remain infectious until decomposition is well advanced.

Rabies is the most important public health hazard associated with bats. Infection with rabies has been confirmed in all 40 North American species of bats that have been adequately sampled in all of the contiguous United States and in most provinces of Canada. Figure 8 shows the frequency of bat species submitted for rabies testing in New York State over the last 12 years. While not a nationwide measure of human encounters with bats, Figure 8 illustrates that bat species are not encountered equally. Note that bats submitted for testing are often ill and/or easily captured. The numbers and species encountered will vary with the region of the country; data are generally available from local and state health authorities.

Random sampling of bats (healthy and ill) indicates an overall infection rate of less than 1%. Finding a rabid bat in a colony does not imply that the remaining animals are rabid. In fact, the probability of immediately finding more than one additional infected bat in that colony is small.

Bats rank third (behind raccoons and skunks) in incidence of wildlife rabies in the United States (Krebs et al. 1992). In the last 20 years, however, there have been more human rabies cases of bat origin in the United States than of any other wildlife group. Furthermore, the disease in bats is more widely distributed (in all 48 contiguous states in 1989) than in any other species. In Canada, bats also rank third (behind foxes and skunks) in the incidence of wildlife rabies. Therefore, every bat bite or contact must be considered a potential exposure to rabies. While aerosol transmission of the rabies virus from bats in caves to humans and some other mammals has been reported, this is not a likely route of infection for humans entering bat roosts in buildings in temperate North America. Note that vampire bats are not a threat north of Mexico.

Histoplasmosis?General Epidemiology
Histoplasmosis is a very common lung disease of worldwide distribution caused by a microscopic fungus, Histoplasma capsulatum. Histoplasma exists in nature as a saprophytic mold that grows in soil with high nitrogen content, generally associated with the guano and debris of birds (particularly starlings, Sturnus vulgaris, and chickens) and bats. Wind is probably the main agent of dispersal, but the fungus can survive and be transmitted from one site to another in the intestinal contents of bats, and also in the dermal appendages of both bats and birds. The disease can be acquired by the casual inhalation of windblown spores, but infections are more likely to result from visits to point sources of growth of the fungus. Relative to bats, such sources include bat roosts in caves, barns, attics, and belfries, and soil enriched with bat guano.

Numerous wild and domestic animals are susceptible to histoplasmosis, but bats (and perhaps the armadillo) are the only important animal vectors. Unlike bats, birds do not appear to become infected with the fungus. Both the presence of guano and particular environmental conditions are necessary for H. capsulatum to proliferate. In avian habitats, the organism apparently grows best where the guano is in large deposits, rotting and mixed with soil rather than in nests or in fresh deposits. Specific requirements regarding bats have not been described, though bat roosts with long-term infestation are often mentioned in the literature.

While histoplasmosis in the United States is particularly endemic to the Ohio-Mississippi Valley region (which is also an area with the greatest starling concentration) and areas along the Appalachian Mountains, it is also found in the lake and river valleys of other states. Outside areas with ?appropriate? environmental conditions, there also occur scattered foci with high infection rates usually associated with caves inhabited by bats or birds.

When soil or guano containing H. capsulatum is physically disturbed, the spores become airborne. Persons at particular risk of histoplasmosis of bat origin include spelunkers, bat biologists, pest control technicians, people who clean out or work in areas where bats have habitually roosted, and people in contact with guano-enriched soil ? such as around the foundation of a building where guano has sifted down through the walls.

Infection occurs upon inhalation of spores and can result in a variety of clinical manifestations; severity partially depends on the quantity of spores inhaled. The infection may remain localized in the lungs where it may resolve uneventfully; this is the case for about 95% of the 500,000 infections occurring annually in the United States. Such infections are identified only by the presence of a positive histoplasmin skin test and/or calcified lesions on routine radiographs. Other individuals may have chronic or progressive lung disease requiring treatment. Less severe forms of these infections may be accompanied by fever, cough, and generalized symptoms similar to a prolonged influenza. Resolution of the disease confers a degree of immunity to reinfection. In addition, resolution confers varying degrees of hypersensitivity to H. capsulatum; as a consequence, massive reinfection in highly sensitized lungs may result in a fatal acute allergic reaction.

In a small percentage of chronic histoplasmosis cases, the fungus disseminates to involve multiple organ systems and may be fatal. This form is usually seen in young children (1 year or older) and in immunocompromised adults. In recent years, systemic infections have been increasing in frequency globally as an opportunistic infection of AIDS patients.

Legal Status

The lethal control of bats, even when there is a proven potential danger to humans, often is subjected to careful scrutiny and interagency coordination. A survey of federal legislative actions, court decisions, and agency interpretations concerning bats can be found in Bat Management in the United States (Lera and Fortune 1979).

Some states have laws that specifically mention bats, either providing or denying protection. Others have legislation that applies to bats only by interpretation, since bats may be considered nongame wildlife or indigenous state mammals. Some bats have protection as either federal or state-listed endangered species, but the same state may not protect other species of bats. Enforcement and public education must accompany legislation to accomplish the intended goal of protecting the public and saving endangered bats. Familiarity with the appropriate federal and state laws should precede any nuisance management activities.

Scranton Bat Control

Our professionals at Adanced Wildlife Management will control your bat problems. Bats have long adapted to living in attics and chimneys. Droppings on the outside of your home are usually a sign that you have a bat problem. Aside from bats being a nuisance they do carry a number of diseases and parasites and bat control should only be attempted by a professional.

The following are some of the bat nuisance concerns you may have:

A follow up Bat Watch to ensure no bats are present or roosting on the outside, entering, or exiting, and that the home is secured.





Bat Maternity Season
Maternity season of bats between April 15th and goes through August 15th. Maternity season is when female bats will congregate and have baby bats, known as pups. Pups are born hairless, and require roosts in higher temperatures to stay warm, which is why a attic makes a perfect location, especially when the mother is out finding food. When pups are born, they can not fly. Removal should not be attempted during this time, as sealed in bats can die, or even find their way into the interior of a home. So what can be done during Maternity season? If the bats are causing a health and safety issue coming into the home or causing property damage from their droppings, bats can be removed during this time, only with special authorization from the state wildlife agency by a approved company like Advanced wildlife Management. There will be a lot of mis-communication on this topic if you are researching, as not all companies are properly trained in Bat Compliant standards.


There are several Bat Species in every state, but most nuisance concerns involve the Little Brown Bat, and the Big Brown Bat. All are nocturnal, primarily feeding at low light through dark. Most of their time is spent on roost sleeping until they emerge at dark. Man made structures make excellent areas for bats to roost in a colony. Bats can live 15 years up to 30 years in the wild and have between 1 and 2 pups a year between Mid April – Mid August. Most people wonder how a bat can find food at night? They use echolocation or bouncing of sound waves to navigate and feed. Colonies of Bats can be very noisy from moving in the walls to high pitched chirping and smells from fecal accumulations or large colonies can drive people from a structure.

How To Prevent Bats In Your Home
Preventing bats from entering your home, attic, or building, is relatively easy. Close up or repair all possible or potential openings. Bats can get into the smallest openings as small as 3/8″, so keep that in mind. Being proactive and addressing openings before they happen to be used by a bat is key, especially if you have bats in your area. Most openings can be easily determined, but there are openings that are not easily seen, which is why it is best to hire a professional.


Bat Damage and Diseases

Once bats have decided to move into your attic, there can be a concern. Bat colonies can produce the quickest amount of fecal accumulation of any animal, even though remarkably small in size. In a attic, it can be bad news if it covers insulation and duct lines. Droppings in a enclosed, limited air space like a attic, do not breakdown naturally as if outside, and can harbor virus, pathogens, bacteria, fungus, and disease.

Histoplasmosis, fungus that grows on bat droppings is one of the top concerns. As droppings dry, disturbance to droppings from the bats moving over droppings, or someone walking over droppings can circulate particulates becoming airborne. People and pets can be at risk of getting histoplasmosis. Rabies is the other disease that should be a concern, and according to the Health Department, they suggest if you are in the same room with a bat, you need to get checked out or pre rabies shots, and Centers for Disease Control suggests scratch or bite to seek medical attention immediately. Presence of ectoparasites in bats can be of a concern. Of the more than 50 ectoparasites in bats, the most noticeable are Bat bugs, Mites, Ticks, Fleas, and Flies. The presence of ectoparasites can usually be seen once the hosts or bats are removed, and the ectoparisite searches for a new host.

How Do I Get Rid Of Bats
Getting rid of bats can be challenging for someone untrained, which can easily make the problem much worse. Successfully removing a Bat Colony should be done by exclusion of the bats, a process that allows them to fly out but not fly back in, only after every possible and potential secondary openings are permanently sealed off. Bats should never be trapped or poisoned as they are Federally Protected. Bats should not be disturbed or removed during pup season, when they give birth. This can range in time depending on geographical are and species of bats, but usually mid April – mid August. Removal of Bats should not be the only concern, as droppings will need to be removed as well. Follow these steps to aid in removal of bats from a building or structure.


Perform a inspection of the building by trying to identify the location of the bats, openings they are entering, and a survey of damage. Bat Watches performed right before dark can allow you to visibly see where bats are exiting, as the drop from their roosting area.
Perform a attic inspection, paying special attention to time of the year and species of bats, damage in your attic, or fecal accumulation areas. Bats should not be disturbed during certain times. Professional help is recommended.

Repair and seal all secondary openings, leaving the main and problem opening undisturbed. This is a important step as if anything is missed as bats are excluded, they will have a opening to re enter. It is also important not to disturb the primary areas as it could cause the bat colony to split or move to another part of the home.
Exclusion of the bats, or installation of excluders on primary openings to allow bats to fly out, but not fly back into the structure. This is recommended by a professional only, and can end in disaster if the bats are trapped in, or using improper excluders.

Bat Repellents
Bat problems can become costly, especially if the problem has occurred for a long amount of time. We receive requests asking if there is a effective repellent or frequency device that does repel or scare away bats. Having seen thousands of bat problems, I can tell you that there is no effective repellent or sound frequency that deters bats. We have seen people try sprays, frequency devices, ammonia, ultra sonic sound devices, moth balls, bright lights, natural ingredients, aerosols, and even loud playing radios, to no avail. Simply, bats possess excellent homing capabilities, and will return to a roosting location, over-riding any repellent. It is also illegal to harm or harass bats with sounds, sprays, lights, and toxic substances. If you are experiencing a bat problem, do not take the law into your own hand, and call a professional at Advanced Wildlife Management
