Less than a week left to legally block bats from your Florida home before maternity season

Illegal in Florida to kill or harm bats; Here’s what you need to do instead.

If you’ve lived in Florida long enough, you know that critters are just part of the equation. From raccoons and birds of all kinds to gopher tortoises, gators and bats. Living in the Sunshine State means sharing our habitat.

But the Florida Fish and Wildlife Conservation Commission (FWC) shared an important reminder that April 15 — this Saturday — marks the start of bat maternity season in Florida.

That’s the last day you can legally “exclude” — remove and block — bats that are roosting in your home or building.

Florida has 13 native and beneficial bat species, the FWC says, and they typically roost in trees, caves or other natural spaces.

But they can also be attracted to human-made structures, particularly buildings undergoing major construction because they have easier access.

Bat maternity season, the time when bats give birth and raise their young, runs through Aug. 14. During that time, it is illegal to block bats from their roosts. If bats are excluded during maternity season, flightless young can be trapped inside the structure and die, which isn’t good for you or the bats, the FWC said.

It is only legal to use exclusion devices from Aug. 15 through April 15. Permits are required to use exclusion devices outside of those dates.

Exclusion devices, which allow bats to safely exit a structure but block them from returning to roosts, are the only legal and most effective method to remove bats from your home or building.

It is illegal in Florida to kill or harm bats, so exclusion guidelines were developed to ensure bats are excluded safely and effectively from buildings outside of maternity season.

Bat exclusion is a multi-step process that begins by identifying all potential bat entry and exit points in a building. To legally exclude bats, exclusion devices must be installed on key exit points, left up for a minimum of four nights and the exclusion must be conducted when the overnight temperature is forecast to be 50ºF or above.

Bats are beneficial, both ecologically and economically, the FWC pointed out. They serve critical functions worldwide due to their roles in insect pest control, and as pollinators and seed dispersers, plus their guano can be a valuable fertilizer.

Florida’s bats are insectivores and a single bat can eat hundreds of insects, including mosquitoes and other garden and agricultural pests, each night.

Florida’s native bat populations include endangered species such as the Florida bonneted bat. Want to help our bats? There are several ways that Florida residents and visitors can support bat conservation:

Preserve natural roost sites, including trees with cavities or peeling bark.
Leave dead fronds on palm trees to provide roosting spots for bats.
Install a bat house on your property.
Report unusual bat behavior, as well as sick or dead bats:
