Could There Be Bats in Your Attic?

Bats play an important role in the ecosystem as pollinators. In fact, more than 500 species of plants, including types of cocoa, need a healthy bat population for pollination. Bats also provide natural pest control by eating insects like mosquitoes. These benefits notwithstanding, you definitely don’t want bats in your attic. They can spread diseases and cause damage, so call a pest control company if you notice any of the following problems:


One of the easiest ways to tell if there are bats in your attic is to look around for bat droppings, which are called guano. Bat droppings resemble mouse poop, but they are a little larger. Guano is irregularly shaped, and may have visible insect parts in it. You can usually find guano in piles near openings to the house. Guano can also be present on windowsills, decks, and porches. Bat droppings have a distinctive smell similar to ammonia.


Bats are very quiet, nocturnal mammals. It’s possible to have a colony of hundreds of bats in your home without noticing any major sounds. Bats do make a quiet chirping sound, which you might hear at dusk or dawn. Scratching and scurrying noises may also indicate a bat infestation.

Greasy Spots

The coat of a bat is greasy. When a bat clambers in and out of your home, the grease on the coat can rub off on the house. Look for grease-like stains on the exterior of your house, including on the walls and roof.

Visible Animals

Since bats tend to be fairly discreet, the only way some homeowners can tell that they have a colony is by actually seeing the bats as they leave or enter the house. If you suspect you may have a bat infestation, set up a lawn chair in your yard, facing your home, and watch your house. Go out before dusk or before the sun rises, and look for bats flying around.
