Here’s how to get rid of them.

Have you heard scratching, squeaking, or fluttering in your attic? It could be bats. It is not uncommon in Ann Arbor to hear these flying mammals hiding in your attic during the night.


How do you know if you have bats in your attic?

In order to get bats out of your attic, you first need to determine if it’s really bats you’re dealing with, or another critter. The signs of bat activity are similar to other rodents, so the easiest way to know is by physically seeing them. Bats will nest indoors in areas that are dark, undisturbed, and have easy access to the outdoors at night. If you don’t visually see a bat, here are some other signs you may notice.


Signs you may have a bat in your attic:

You see:

  • Piles of droppings in one corner of your attic or near an entry point
  • Droppings on the attic insulation
  • Stains on attic walls

You smell:

  • A strong smell of ammonia, which is caused by excrement

You hear:

  • Squeaking or chirping
  • Scratching
  • Fluttering

How did bats get into my attic?Bat entry point

Bats often find shelter in Ann Arbor homes during winter to escape the cold weather or to give birth to their young. Bats are able to easily enter attics through small openings or narrow gaps high on your house. They may also enter under loose-fitting doors, around windows and through gaps around conduits and utility vents. Bats only need an entry hole the size of a dime. Bats prefer attics over closets or living rooms because it is similar to their native shelter (trees, caves, and crevices).

How do I keep them from coming back?

Now that we have safely and successfully removed the bats from your attic, it is important that you put measures into place to keep them from coming back. Bats are creatures of habit and will keep returning to the same spot year after year if measures aren’t put in place to keep them out.

Seal up any holes

The easiest way to prevent bats from returning is to seal up the holes they entered from. Remember that bats can get through holes the size of a dime, so be diligent when sealing up holes.

Clean up any mess

While wearing protective gear (gloves, masks, easy to clean clothes) collect any loose droppings or debris and dispose of them. Disinfect the area and dispose of any contaminated insulation or damaged wood.

Keep your house clean and cleared

Get rid of unnecessary items and clutter in your attic. This will discourage bats from viewing your clutter as nesting potential or protection from the elements.
