What it is
Flying mammals that commonly roost in attics, wall voids, chimneys, trees, and other sheltered locations. They are beneficial insect predators, but structural entry and accumulated droppings can create nuisance and health concerns.
How to recognize it
Small flying mammals. Squeaking or scratching in walls at dusk, droppings (guano), and stains around entry points.
Where you will find it
Attics, wall voids, chimneys, and under eaves.
Why it matters
Bats are protected in many areas, and removal has legal timing rules. Never handle one, and contact a doctor if one was in a room with a sleeping person or child.
What to do
- Do not approach, handle, or feed wildlife, and keep children and pets away.
- Keep trash secured and pet food indoors.
- Note where you see activity, but do not block or seal an opening yourself. Animals trapped inside can cause more damage.
- Contact a licensed wildlife professional. Local and state laws often apply.
When to call a professional
- An animal is inside the home, attic, or crawlspace.
- You see signs of nesting or droppings.
- An animal appears sick or aggressive, or you may have been bitten or scratched (seek medical care).
