MONTPELIER - Summer is when some species of bats gather in colonies to raise their young in human-made structures such as houses, barns, office buildings, and bat houses.
Finding and sealing off holes on the inside of the home, such as around attic doors or chimney flues, will keep bats out of living spaces and can be done any time of year.  However, during the summer when bats have flightless young, do not attempt to seal holes on the outside of the house where bats come and go; this practice can result in more bats in the home.
