General Bat Biology

Mating

Fall and winter with the female carrying the sperm in utero until spring when ovulation and fertilization occurs. Bats are born in May through July. 

Hibernation

Bats prepare for winter when the first frost occurs. Little & Big Brown species migrate short distances. Bats in the northern United States go into a semi-dormant hibernation from September through May.

Endangerment

While bats can live up to 20 years, a startling number of bats are dying from pesticides, and insects containing pesticides, disturbed maternity roosts and hibernation areas by human activity, sealing/flooding of mineshafts, and forestry elimination. 

Habitat

They live in buildings, trees and caves as well as under rocks and wood piles. They feed on mostly small insects and forage over bodies of water or in the woodlands nearby water. 

Diseases

The 2 most common diseases spread to humans by bats is Rabies and Histoplasmosis. Bat-to-bat diseases include the White-Nose Syndrome, a fungus that can kill 100% bats in a colony in hibernation. 

Damages

Bats can gnaw on wood to gain entry into buildings. Bat dropping and urine can degrade roofing materials which cause leaks and odor issues. Health risks are also damaging to human and bird populations. Typically, after August is the best time to get rid of bats to ensure that flightless young are not left behind in a dwelling.
