Does one bat in the house mean more? One random bat in the house doesn't always mean anything. Most of the people that call us have had at least two or three instances of bats in the house over the last few years though. Multiple bats in your house is a very strong indication of an infestation. Most bat colonies found in houses are maternal colonies.
Bats are usually able to exist near human homes without making their presence known. However, with decreasing amounts of habitat available for bats (e.g., trees being cleared), bats may find their way into man-made structures. Bats use existing openings (cracks as small as 1 ΒΌ inch by 3/8 of an inch) to enter buildings or to roost in attics.
Here are the top 7 signs that bats have infested your attic:
- You see the bats flying around your house during sunrise/sunset.
- Bats droppings/ guano.
- A Chirping sounds.
- Presences of guano in the attic.
- Scratches on the Walls.
- Presences of Brown/Black Stain Around Entry/Exit Points.
- Presences of Dead Bats Around your property.
How do I bat proof my house? Use window screens, chimney caps, and draft-guards beneath doors to attics, fill electrical and plumbing holes with stainless steel wool or caulking, and ensure that all doors to the outside close tightly. Prevent bats from roosting in attics or buildings by covering outside entry points. CDC Bat Management
Do vampire bats really exist? Yes, but not in most of the United States. Of the three species of vampire bats in North America, only a single specimen has been recorded for the United States in extreme southwest Texas. Vampire bats do not suck blood--they make a small incision with their sharp front teeth and lap up the blood with their tongue.
What should I do if I find dead or dying bats, or if I observe bats with signs of White-nose Syndrome? If you find a dead or dying bat: Contact your state wildlife agency, file an electronic report in those states that offer this service, e-mail U.S. Fish and Wildlife Service biologists in your area, or contact your nearest Fish and Wildlife Service field office to report your potential White-nose Syndrome (WNS) observations.
