Bats are among the trickiest, and most regulated, wildlife problems a Marietta homeowner can face. Timing matters enormously with bats, so understanding the season helps you know what to expect and why the fix isn't as simple as sealing a hole.
When bats are active
Bats are most active in Georgia through the warm months, roughly spring into summer, when they emerge to feed on insects each evening and seek out warm, sheltered roosts during the day. An attic, dark, warm, and undisturbed, is close to ideal from a bat's perspective, which is why they end up in homes.
The maternity season is the critical window
Here's what makes bats different from other attic invaders: there's a maternity period in the summer when females gather to give birth and raise pups that can't yet fly. During this window, you cannot simply seal a bat colony out. Doing so would trap flightless pups inside your home, which is both inhumane and creates a much worse problem. Proper exclusion has to be timed around this period.
Why you can't just trap them
Bats aren't trapped like raccoons or squirrels. They're removed through exclusion, one-way devices that let them leave to feed but block their return, so the colony empties out on its own. Bats are also protected, and there are legal requirements around how and when they can be excluded. This is genuinely not a DIY situation, and not one for a general handyman.
The health angle
Bat guano accumulates quickly beneath a roost and can carry pathogens, so cleanup and decontamination are part of resolving a bat problem. And any situation where a bat may have had contact with people or pets indoors is something to take seriously and address promptly.
What to do if you have bats
If you're seeing bats around your roofline at dusk, finding droppings beneath a particular spot, or hearing scratching and squeaking near the eaves, you likely have a roost. The right move is a professional inspection that accounts for the season and the legal requirements, not a quick DIY seal that could trap a colony inside.
