When should I put up a bat house?
Bat houses can be put up any time of the year. However, it is best when putting up a new bat house to have it up before the start of spring. In colder regions, bats return from hibernation and migration in the spring, looking for a place to roost and have their young. It’s best not to delay the attachment of your bat house as their other roosts may become unavailable anytime of the year, requiring them to search out a new home. Your bat house will be a potential location.
If you are doing a bat exclusion from your home, we recommend putting up a bat house before the exclusion. This allows the bats to have a place to go after they are evicted from your home.
