Bat Removal & Exclusion in Duluth, GA
Dark droppings piling up on the porch or driveway under one spot, or a few bats leaving the roof at dusk? Bats are roosting somewhere in your Duluth home, and they have to be removed at the right time of year. Call us and tell us about the job — we will confirm the local crew for your county before any work starts.
Bats in your Duluth home
Bats do well in Duluth. The tree cover and the woods along the Chattahoochee produce plenty of night-flying insects, and the bats that feed on them need a dry place to roost during the day. A house works fine. In Georgia attics, the bats are mostly big brown bats, with little browns in some places. They don't make much noise, so the usual first sign is a pile of guano on the ground directly below where they're getting in. It might be on a porch roof, a deck, or along the driveway under a gable.
Each kind of Duluth house gives bats different spots to use. Older homes have gable louvers with gaps, loose fascia, and old chimneys. Newer homes and townhomes have narrow gaps where a roof meets a wall or where trim pieces don't quite line up, and a bat only needs a very small opening. No matter where they're getting in, the rules don't change: bats are protected, they can't be killed, and they can't be sealed in while pups are too young to fly.
Find the guano, then look up
The quickest way to find a bat entry is to look for droppings on the ground and then look straight up. Bat guano looks like dark mouse droppings, but it crumbles into powder when crushed and builds up in one spot. On an older Duluth home it often collects under a gable vent or chimney. On a newer house it tends to show up below a roof-to-wall joint or a corner where the trim doesn't meet tightly. You may also see dark stains around the opening. A pro confirms the entry by watching the bats come out at dusk and checking for other openings you might have missed.
April 1 to July 31: the maternity season
Every spring, female bats gather to give birth, and the pups can't fly for several weeks. That's why exclusion is not done from April 1 through July 31. If the openings are sealed during that time, the adults get out but the pups are trapped inside and die. Georgia DNR allows exclusion during that window when a licensed Nuisance Wildlife Control Operator does the work, but good operators only do it when they can confirm there are no flightless young, or when there's a real health risk. Otherwise, the advice is to wait until August. An inspection can still be done any time so you have a plan ready.
Guano and health risks
Dried bat droppings can carry the spores of the fungus that causes histoplasmosis, a lung infection. The spores get into the air when the guano is disturbed, so don't sweep it up dry. When guano can be removed safely, it should be, and a pro does that with containment and protective equipment. Insulation replacement is a different question. Some companies recommend replacing all the insulation when only part of it is actually contaminated, so ask for photos. Also, if you find a bat inside your living space, especially in a room where someone was sleeping, don't touch it or let it go, because bats can carry rabies. Call public health for advice.
How one-way exclusion works
The pro installs bat valves, one-way devices that let bats crawl out to feed but not get back in, over the active openings, and seals all the other gaps around them. Most bat jobs take two or three visits: one to install the valves, then another to confirm the roost is empty and seal the last openings permanently. If the bats are only in a gable vent and not in the attic, the job can be fairly small. A large colony with a lot of guano in the attic is a much bigger job. The pro will tell you which situation you're in after the inspection.
Don't seal it yourself, and skip the gadgets
Once people see where bats are getting in, they often want to fill it with caulk or foam. Don't. If bats are inside, especially between April and July, sealing the hole traps them, and they'll either die in the wall or find a way into the living space. Ultrasonic devices and repellent sprays don't make bats leave, and mothballs shouldn't be used for any wildlife problem. The approach that works is always the same: inspect, wait for the right season, install one-way valves, confirm the bats are gone, and then seal.
