If you are trying to get bats out of your home or outbuilding, this is the time of year to do so. Unfortunately, because this is the best time of year, bat colonies are on the move. Colonies can combine and make a small colony significantly larger and you could become their next accidental landlord.
The good news is, we can help. This is the best time of year for evicting bats. Each female bat often fledges two pups by mid-July, early August, the pups can fly and begin hunting insects on their own.
Now is the best time to keep them from coming back. If you do it any earlier in the year, you risk harming the colony by trapping the young inside your building; if you wait late into the fall, you risk missing the hibernation window and forcing them to find an alternate exit.
