Bat Removal & Exclusion in Marietta, GA
Little dark droppings piling up on the ground or the porch under the same spot every morning? That's the number-one sign of bats in a Marietta home, and the fix depends on the calendar. Call us and tell us about the job — we will confirm the local crew for your county before any work starts.

Bats in your Marietta home
Most Marietta homeowners find out they have bats from the ground, not the attic. The giveaway is droppings piling up below the same spot — under a gable vent, along the porch beneath the eave, or at the base of a chimney. Bats don't chew or scratch much, so a colony can live in a house for a long time before anyone notices. The species usually involved here are big brown and little brown bats.
Where they roost tends to follow the house. The ranches common across Marietta have gable vents at each end of the attic, and a bat can slip behind the louvers easily. Older homes near the Square add loose trim and chimneys. Newer homes have small construction gaps where roof sections meet. Bats are protected, so the job is a scheduled exclusion, never extermination — and the schedule is set by when the young can fly.
The calendar: April 1 through July 31
From April 1 to July 31, bat colonies in Georgia are raising pups that can't fly. If the exits are closed during those months, the young die inside. Unless the bats pose a real health risk, pros leave a colony alone until that window ends — and if they can't confirm there are no flightless young, they wait. When it truly can't wait, Georgia DNR allows exclusion inside the window by a licensed Nuisance Wildlife Control Operator. An inspection can happen any month, so you're ready the day the window opens.
Bats in a gable vent vs. a colony in the attic
On a lot of Marietta ranches, the bats are living only in the gable vent — the space between the louvers and the screen — not out in the attic itself. That's a smaller, simpler job. A colony that has spread into the attic, with droppings across the insulation, is a bigger one: more openings to treat, more visits, and real cleanup. The inspection tells you which you're dealing with, and that's the biggest difference in what the work involves.
Guano and histoplasmosis
Bat droppings can carry the fungus that causes histoplasmosis, a lung infection you get by breathing in spores from disturbed guano. Don't sweep it up or vacuum it with a household vacuum. Where it can be removed, it should be, with proper protection. One thing to watch for: some companies recommend tearing out and replacing all the insulation when that isn't actually needed. Ask the pro to show you how far the droppings have spread before you agree to a full replacement.
How exclusion works
The pro finds every spot the bats are using, then hangs a bat valve or one-way device over the active exits. The bats leave at dusk to feed and can't get back in. After a visual check confirms the roost is empty, the openings are sealed with metal. Most bat jobs take two or three visits: one to set the valves, time for the colony to move out, and a return to seal and clean. A small gable-vent job can sometimes be done in a day.
Don't caulk the hole yourself
It's tempting to fill the gap the minute you see bats coming out of it. Don't. Sealing before every bat is out traps them inside — pups included in summer — and you end up with dead animals in the wall and a protected species harmed. Sprays, mothballs and ultrasonic gadgets don't move a colony either. Find out where they're getting in, then let a pro handle the timing.
