April 15 is the last day to legally exclude bats from your home without a permit: Tricolored bat photo by Faith Flawn, FWC. April 16: Maternity season starts for Florida’s bats Florida’s 13 native and beneficial bat species typically roost in trees, caves or other natural spaces, but are sometimes attracted to buildings and other human-made structures, including buildings still undergoing construction. With bat maternity season starting April 16, the Florida Fish and Wildlife Conservation Commission (FWC) reminds the public that April 15 is the last day to legally exclude bats from buildings without a permit, until Aug. 15. Florida’s bat maternity season, the time when most of our state’s bats give birth and raise their young, starts on April 16 and lasts until Aug. 14 each year. During maternity season, it is illegal to block bats from returning to their roosts. This helps prevent flightless bat pups from being trapped inside structures — something that wouldn’t be good for either people or bats. If you have bats roosting in your house or building, the most effective and only legal method to remove roosting bats from structures is the use of exclusion devices, which allow bats to safely exit a structure but block them from returning to their roosts. It is only legal to use exclusion devices from Aug. 15 until April 15, which is outside of the maternity season. Permits are required to use exclusion devices during Florida’s bat maternity season. Exclusion guidelines were developed to ensure bats are removed safely and effectively from buildings outside of maternity season to avoid problems for people and prevent the killing or harming of bats, which is illegal in Florida. 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 highly beneficial, both ecologically and economically. Florida’s bats are insectivores, with a single bat eating up to hundreds of insects a night, including mosquitoes and other garden and agricultural pests. Worldwide, bats serve critical functions due to their roles in insect pest control, and as pollinators and seed dispersers, and their guano can be a valuable fertilizer. Our state’s native bat populations include endangered species including the Florida bonneted bat. Want to help our bats? There are several ways that 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. – Add native plants when landscaping your property to attract native pollinators and benefit bats. – Report unusual bat behavior and sick or dead bats to MyFWC.com/BatMortality. – Volunteer with the Florida Bat Force!
