Bat Removal & Exclusion in Savannah, GA

Bats roosting in your Savannah attic, chimney or masonry wall

Bats are the hardest tenant to notice in a Savannah building, and the city's architecture is exactly why. There's no gnawing and no scampering — only a faint chitter at dusk, an oily dark stain at a cornice or gable, or droppings gathering on a sill below a vent. Aged brick masonry and old wood-frame homes give a colony an abundance of what it wants: deep historic attics, decorative vents, original uncapped chimneys, and the weathered mortar joints, parapet gaps and loosened trim that come with a century-old structure. And because a bat needs only a sliver of a gap, even a carefully restored historic home can host one.

Two things set bats apart from every other animal that gets into a Savannah roof, and a trap addresses neither. Bats are protected and ecologically valuable, so the work is a lawful, carefully timed exclusion rather than extermination. And for part of the year the colony is raising pups that can't yet fly, when shutting the adults out would entomb the young inside. With bats, it's the date on the calendar — not a trap in the attic — that dictates when the job can run, and a licensed Chatham County pro builds the whole approach around it.

Timing is the law: nothing between April 1 and July 31

For the span of April 1 to July 31, Georgia's bat colonies are raising pups that can't yet fly, and across those four months an exclusion is prohibited. Close the openings while the young are grounded and you seal them in to die — a protected-species violation and a serious biohazard at the same time. So a responsible pro keeps the inspection available in any month but schedules the exclusion for a lawful window: the brief early-spring stretch before the births, or — far more often — late summer into fall, once every pup can fly and the colony can leave on its own. On the coast that fall window frequently runs later than it does inland or up north.

Why the guano matters: histoplasmosis

A colony returns to the same roost night after night, and in the deep attic of an old Savannah building the guano accumulates — eating at surfaces, soaking insulation and old timber, and heaping where the bats hang; the coastal humidity only helps it spread and persist. The real hazard, though, is biological: the droppings can carry Histoplasma, a fungus whose airborne spores cause histoplasmosis, a lung disease. That's why the cleanup half of a bat job is true biohazard remediation — the space contained, the contaminated material removed, the surfaces treated — and not a quick pass with a vacuum.

The way bats get into an old Savannah building

A bat doesn't force or gnaw an opening; it threads a gap that is already there and leaves no damage at the entry, which is why a roost can go unnoticed for years in an old structure. The clearance it needs is tiny — about three-eighths of an inch — so even a tightly restored historic home isn't immune. In Savannah the usual ways in are weathered mortar joints and parapet gaps in masonry walls, the seams where aged fascia meets soffit, decorative and louvered vents, and the flues of uncapped chimneys. With a gap that small, finding every live entry on an old building is exacting work — miss one and the colony just shifts to it.

What a done-right exclusion involves

Done correctly, an exclusion harms no bat. The pro first maps every candidate opening and identifies the live exits, then fits one-way doors over them — at dusk the bats drop out to feed and find the way back closed. After a run of nights confirms the roost is empty, the openings are sealed permanently, and only then do the guano cleanup and remediation begin. Sequence is everything: seal too early and bats are trapped inside, so an accurate exit count and patience carry the job — work that takes extra care on an old building with many possible openings. No spray, no ultrasonic device, no poison: for a protected species, exclusion is the method.

The home-remedy seal that traps bats

The most damaging bat mistake is the well-meant patch of mortar or caulk. Seal the gap during the maternity months and the flightless pups are trapped; seal it before the whole colony has left and the adults are trapped — either way you end up with dead bats inside an old wall, plus a legal problem, since the species is protected. No repellent or ultrasonic gadget reliably drives a colony out. In any month, the right first move is an inspection, then exclusion in a lawful window — not a tube of sealant on a humid afternoon.

A bat inside, and the rabies precaution

Bats more than earn their place — one can eat thousands of insects a night, and Savannah's river and marsh keep the coastal air thick with them — and they would much rather avoid people. Even so, any wild mammal can carry rabies, so a bat loose inside a living space, especially near someone asleep or a child, shouldn't be handled and may warrant a call to public health about testing. Worth noting too: the tricolored bat, found in this part of Georgia, is under federal review for possible listing — one more reason to leave a roost to a pro working the maternity calendar rather than disturbing it.
