HOW TO GET BATS OUT OF YOUR ATTIC

SUMMARY

This guide explains how to safely and humanely remove bats from your attic while protecting both your home and local wildlife. Learn how to identify their entry points, use one-way exclusion devices, and prevent future infestations responsibly.

FEATURES

• Identify Signs of Bats: Look for droppings (guano) and squeaking sounds.

• Use One-Way Exclusion Devices: Allow bats to leave but not re-enter.

• Avoid Direct Contact: Bats can carry rabies and other diseases.

• Seal Entry Points: Close openings after confirming all bats have exited.

• Schedule Timing Carefully: Never evict bats during maternity season.

• Prevent Re-Entry: Maintain your attic with proper screens and insulation.

GUIDE DESCRIPTION 

Bats are essential for controlling insect populations, but when they move into your attic, they can create serious health and sanitation problems. Guano (bat droppings) can cause strong odors, staining, and respiratory hazards such as histoplasmosis. Fortunately, bats can be removed humanely without harming them — the key is patience and proper timing.

Start by confirming that bats are indeed the culprits. Listen for fluttering or squeaking noises at dusk and dawn, and look for droppings along walls or windowsills. Inspect your attic and roof exterior for small gaps, often near vents, eaves, or chimneys. Bats can squeeze through openings as small as half an inch, so check carefully with a flashlight at night when they are active.

Once entry points are identified, install one-way exclusion devices — such as bat cones or netting — over these openings. These allow bats to exit the attic at night but prevent them from flying back in. Leave these devices in place for at least 5–7 days to ensure all bats have safely exited. Never attempt to trap or handle bats directly, as they may bite when frightened and can carry diseases like rabies.

Timing is crucial. Avoid exclusion during the maternity season (typically May through August), when baby bats are too young to fly. Evicting adults during this time could leave pups trapped inside, leading to both health risks and unnecessary harm. The best times for removal are early spring or late summer when colonies are mobile.

After confirming that the bats have left, seal all entry points using durable materials such as caulk, metal flashing, or heavy-duty mesh. Inspect other vulnerable areas — vents, rooflines, and chimneys — to prevent new colonies from entering. If your attic has significant guano buildup, wear protective gear and use disinfectants to safely clean and sanitize the area.

Finally, implement preventive measures. Keep outdoor lights off near entry points, as they attract insects that draw bats closer. Install bat houses nearby to provide an alternative roosting space away from your home. These simple steps protect both your property and the bat population, promoting coexistence without conflict.

By using these humane methods, you can restore safety to your home while allowing bats to continue their important ecological role as natural pest controllers.
