Out of the seven species of bats that we have in Minnesota, three are tree dwellers and have little or no interaction with man. The other four species of bats found in Minnesota are cave dwellers, and unfortunately our homes appear to a bat as a large, convenient cave. The two species of bats that cause the majority of problems in Minnesota are the Large or Big Brown bat (Eptesicus fuscus), and the Little Brown bat (Myotis lucifugus).

If you live in Minnesota and you are having a problem with bats in your home, the only proven method of resolving this situation is through the method of exclusion. This bat friendly process was developed some twenty years ago by the nations leading bat specialist Dr. Merlin Tuttle who went on to establish the organization Bat Conservation International based in Austin, Texas.

At Exclusive Batproofing of Minnesota, our process of exclusion is the method whereby the bats in question are allowed to exit the structure through a one way device that we make and call the Excluder. We mount the Excluder at the exit sites that they are already using. This allows them to exit the structure without any hindrance (bats generally go out to feed every night or two). Because of their longevity (30 yrs.), and reluctance to change living quarters, all other possible reentry sites need to be sealed to prevent the bats from finding a new way into the structure. This includes any crack 1/4" wide by 1" long, (the width of a pencil bv one inch long), or a hole roughly the size of your thumbnail. Within a few days all the bats living in the structure will exit through the Excluders and because of their inability to reenter will out of necessity move on to find a new place to call home. We guarantee that once we bat proof your home you will be bat free. If any possible entry sites are missed and not sealed, the bats in their nightly search of the structure will find it and reenter the building. For this reason, although we have a less than a 3% call back, we give the homeowner a 1 year warranty/service period - so that if there is a reoccurrence, we will return at no further charge to take care of the problem. Once the bats have been successfully excluded from the home, simply keeping up with your normal home maintenance will ensure your being bat-free for many years to come.

Our process is guaranteed effective. We batproof throughout all of Minnesota. No fee's are charged for travel. Cost is based on the physical features of the home. For a free estimate and further information on how to get your Minnesota home batproofed call:
