You’ve probably heard the phrase “bats in the belfry” at least once in your life. Maybe in reference to an old aunt, or perhaps that crotchety neighbor down the street with the impressive collection of lawn gnomes in his front yard… But if you actually have bats in the belfry and don’t know it, you might find yourself wondering if you’re not going a little bit mad, too!
Early summer is an exciting time of year for bats because this is when they birth and begin raising their young. They all will seek out roosts in dark, enclosed spaces. Large and small brown bats (the two species most common in the Northeast) do not build nests. They prefer to hang from rafters or creep into crevices. Male bats tend to rest in cooler climates during the day, either alone or in small groups. However, pregnant female bats (and new mothers) prefer warmer spaces (like that non air-conditioned attic or crawl space…) and roost in large groups, sort of like a nursery!
So, if you hear a rustling and squeaking coming from upstairs, you probably haven’t lost your marbles. You may just actually have bats in your belfry!
