How can I get bats off a balcony? - briefly
Seal all cracks and openings on the balcony, then install a one‑way exclusion device that lets bats exit but prevents re‑entry; if the problem persists, contact a licensed wildlife‑control professional for safe removal.
How can I get bats off a balcony? - in detail
Bats may roost on balcony structures when they find crevices, overhangs, or loose screens that provide shelter. The first step is to confirm that the animals are indeed bats and not birds or insects; bats are nocturnal, have a distinctive wing shape, and emit high‑frequency sounds that are often inaudible to humans.
Inspection and exclusion
- Examine all joints, gaps around railings, and the underside of the roof for openings larger than ¼ inch.
- Seal minor cracks with silicone caulk or expanding foam; larger voids require hardware cloth (1/4‑inch mesh) secured with screws and staples.
- Install bat‑proof screens on doors and windows; ensure they overlap tightly and are free of tears.
Humane removal techniques
- Deploy a one‑way exclusion device, such as a netted funnel or a PVC tube, that allows bats to exit but prevents re‑entry. Position the device over the primary entry point at dusk, when bats leave to feed.
- Use a temporary mist net or handheld capture bag to collect any individuals that remain after the exclusion period; release them at night at least 500 feet from the building.
- Apply a low‑toxicity repellent (e.g., a mixture of water and a few drops of peppermint oil) around the perimeter; reapply after rain. Repellents deter but do not harm the animals.
Legal and health considerations
- Verify local wildlife regulations; many jurisdictions protect bats and require a permit for removal.
- Wear disposable gloves and a face mask when handling bats to prevent exposure to rabies or histoplasmosis.
- Disinfect tools with a 10 % bleach solution after each use.
Post‑removal maintenance
- Install a solid railing cap or a continuous metal flashing to eliminate future attachment points.
- Trim vegetation that overhangs the balcony, reducing shade that attracts insects and, consequently, bats.
- Schedule periodic inspections, especially before spring, when bat colonies expand.
Following these steps removes the current occupants, prevents re‑colonization, and complies with wildlife protection standards.
