Sharing What We’ve Learned About Bats
BATS IN MINNESOTA
Bats are fascinating creatures and deserve to be understood.
There are upsides to bats as well as downsides. The following will discuss some of these aspects.
Eight species of bats can be found in Minnesota. Four species (Little Brown Bat, Northern Long Ear, Big Brown Bat, and Eastern Pipistrelle) form colonies and can be found in groups. Hibernacula for these include caves, hollow trees, and buildings. These animals typically feed over open fields, along woodland edges, or over lakes and streams. The little brown bat and the big brown bat are most typically the bat species we find infesting structures in Minnesota.
The remaining four types (Silver-haired Bat, Red Bat, the Evening Bat, and Hoary Bat) are commonly called tree bats; their preferred habitat. They lead solitary lives, characteristically roosting in trees and feeding in or around forested areas.

How to Safely Remove Bats from Your Home
If a bat were to get into my house, how would I safely remove it?
Wearing GLOVES, use a container to capture the bat as illustrated above. Do not touch the bat with your bare hands or try to hit it with an object such as a tennis racket.
Why should you never touch a bat with bare hands?
Bats groom themselves by licking their fur. Rabies is found in the saliva of the animal. If you touch a rabid bat who just groomed itself, the rabies can transfer into your system through micro cuts found in the skin on your hands.
Why should you never hit a bat with a tennis racket?
If a bat is hit with a tennis racket, the saliva found on the bats fur due to grooming can be aerosolized and contracted.
