Did you know it is illegal to exclude bats from a structure from April 16th to August 14? Between these times of year mother bats are birthing and raising there young. Young bats may not be able to fly yet and this would cause them to become trapped inside your attic space and they will die. If they are old enough to fly they can become confused and desperate and wind up inside your home. The expired bats can become a bio hazard and smell up your home also.
