Bat Removal & Exclusion in Norcross, GA
A small pile of dark droppings on the ground under a gable vent, or bats dropping out of a roof edge right at dusk? Norcross's older houses and flat-roofed storefronts both make good roosts. Call us and tell us about the job — we will confirm the local crew for your county before any work starts.
Bats in your Norcross home
Bats in Norcross show up in two very different kinds of buildings. On the residential side, the older homes around the historic downtown and the mid-century neighborhoods still have many of their original gable vents and wood trim, and a bat only needs a gap about the width of a finger to slip behind a loose louver or a warped board. On the commercial side, the flat roofs of the older strip-center buildings along Buford Highway have metal edge flashing, parapet caps and sign boxes that pull away over time, leaving narrow, warm crevices bats like.
Either way, the first clue is usually on the ground. A pile of small, dark droppings below a vent, a roof corner or a doorway is the most reliable sign of a roost. Some colonies stay in a gable vent and never get into the attic. Others spread across the insulation. Bats in Georgia buildings, mostly big brown bats and little brown bats, are protected, so they are excluded, never killed, and timing is everything.
April 1 to July 31: the maternity window
From April 1 through July 31, female bats are giving birth and raising pups that can't fly yet. If the exits are sealed during that time, the adults get out but the pups die inside. So exclusions are scheduled for early spring or from August into fall. Georgia DNR does allow exclusion inside the window when a licensed Nuisance Wildlife Control Operator does the work, and good pros only do that when they can confirm there are no flightless young or there's a real health risk. In most cases the answer is to wait. You can still get an inspection any time to plan the job.
Gable vent or full attic
Where the bats are makes a big difference in the size of the job. A small colony living only behind a gable vent louver, which is common on Norcross's older houses, is a much smaller job than a colony that has spread into the attic. A storefront roof edge is different again, because it's often high, long and hard to reach. The pro watches where the bats come out at dusk and checks the attic to see how far the roost goes before quoting.
Guano, histoplasmosis and rabies
Bat droppings, called guano, can carry the fungus that causes histoplasmosis, a lung infection. The spores get into the air when dry guano is disturbed, so don't sweep it up or vacuum it with a regular vacuum. Cleanup is done with protective gear. Guano that can be removed should be, but whole-attic insulation replacement is often recommended when it isn't needed. Ask to see how far the contamination actually goes. Separately, any bat can carry rabies. If a bat is found in a room where someone was sleeping, or near a child, don't let it go. Call your health department.
How the exclusion works
The pro seals every gap except the ones the bats are using, then installs one-way bat valves on those. The bats fly out to feed at night and can't get back in. Most jobs take two or three visits: one to seal and hang the valves, then follow-ups to confirm the bats are gone, take the valves down and seal those last openings. A small gable-vent roost can sometimes be finished in a day. Bats are never trapped or poisoned.
What not to do
Don't seal the hole the bats use, even when it looks like they're all out. If it's the maternity season or some bats are still inside, they'll die in the walls, and you've broken the law protecting them. Don't bother with ultrasonic devices or sprays, which don't move a colony, and keep mothballs out of the attic. The steps that work are always the same: inspect, wait for the legal window, exclude with valves, then seal.
