During spring and summer, female bats search out dark, secluded places to use as nursery roosts. Most species in the United States, such as the little brown bat, big brown bat, Mexican free-tailed bat, and evening bat, prefer to roost in communal groups. Unoccupied attics provide the perfect spots for bats to roost, with warm, dark environments sheltered from predators. The mammals also settle under the eaves of buildings sometimes.

Signs of Bats in the Attic

Unless there is a large number of bats in the attic, infestations can continue for a long time without being noticed by homeowners. Look for the winged animals leaving the attic at dusk and returning sometime during the pre-dawn hours. They can also be detected by noticing stains on exterior walls caused by bat excrement. Inside the house, the smell of guano can become noticeable over time. Large infestations of bats in the attic can deposit enough guano to make the ceiling sag and eventually collapse.

Prevention & Removal

Bats are capable of transmitting rabies, and their excrement can cultivate the growth of histoplasmosis, a fungus that causes respiratory illness in humans. To protect the home from these dangers, individuals must prevent bats from being able to access the attic in the first place. Install vent covers and seal up possible points of entry such as open windows, holes, or loose boards. Homeowners should never attempt to remove a live bat in an attic. Instead, call a professional wildlife removal service. The experts at Trutech can help get rid of nuisance bats, clean out infested attics, and seal up the house so that no more can ever get inside.
