Yes, but it must be done humanely and in compliance with NYC and New York State wildlife protection laws. Bats cannot be harmed or killed during removal. We use one-way exclusion devices that allow bats to leave but prevent re-entry, typically performed outside of maternity season (June-July) when flightless pups are present.

Common signs include squeaking or scratching sounds at dusk or dawn, bat droppings (guano) in attics or near entry points, grease marks around small openings, strong ammonia odors, and sightings of bats entering or exiting your building at twilight. Brownstone residents often notice activity around cornices, roof eaves, and behind shutters.

The complete bat exclusion process typically takes 2-4 weeks. After the initial inspection and sealing of entry points with one-way devices, we monitor for 7-14 days to ensure all bats have exited. Once confirmed, we permanently seal all openings and perform cleanup and sanitation. Historic buildings may require additional time for careful restoration of sealed areas.
