Bat Exclusion, Done to Code
One-way exclusion devices, sealed entry points, and full guano remediation — following Louisiana wildlife regulations to the letter.
Bats belong outside. Not in your attic.
Louisiana is home to a dozen bat species — they are vital predators of mosquitoes and moths, but when a colony moves into an attic or soffit, the guano stains ceilings, corrodes wood, and can carry histoplasmosis spores. Because bats are protected during maternity season (May–August), exclusion has to be done carefully, at the right time, in the right way.
Our Exclusion Process
- Full attic and roofline inspection to locate every entry point
- Install one-way exclusion valves at active entries
- Seal secondary gaps with metal cloth and polyurethane sealant
- Confirm the colony has evacuated (typically 3–7 days)
- Permanent sealing of primary entries once bat-free
- Guano removal, and deep sanitation where nescissary
- Written 5 year warranty on all sealed exclusions
Signs You Have Bats
- Dark greasy stains around attic vents or eaves
- Small pellet-shaped droppings under overhangs
- Squeaking or scratching at dusk and dawn
- Ammonia-like smell from ceilings or walls
- Bats seen exiting the house at sunset
Bat Exclusion — FAQ
Is it legal to remove bats in Louisiana?+
Bats are protected during maternity season (May–August). Exclusion must be done outside that window using one-way devices — never lethal methods. We follow Louisiana Department of Wildlife & Fisheries guidelines on every exclusion.
How do you get bats out of an attic?+
We install one-way exclusion valves at active entry points so bats can leave to feed but can't re-enter. After the colony has evacuated (typically 3–7 days), we permanently seal every entry with metal cloth and polyurethane sealant.
Do I need guano cleanup?+
If the colony has been in place for more than a season, yes. Bat guano stains ceilings, corrodes wood, and can carry histoplasmosis spores. We remove guano, sanitize the space, and replace insulation where necessary.
How long does bat exclusion take?+
One-way exclusion typically takes 3–7 days for the colony to fully leave. Sealing and cleanup add 1–3 more days depending on colony size and access.
Do you warranty bat exclusion work?+
Yes — all sealed exclusions carry a written 5-year warranty.
