Bat maternity season

If you have bats roosting in your attic, eaves or chimney spaces, now is the time to give them an eviction notice. Bat maternity season begins April 15 and runs through August 15. Exclusions of bat colonies must be completed before the season starts.

“During bat maternity season, bats gather to give birth and raise their young,” said Terry Doonan, a Florida Fish and Wildlife Conservation Commission (FWC) biologist and mammal conservation coordinator. “The season lasts until the young bats can fly and feed themselves. In Florida, this occurs from mid-April through mid-August for most bat species.”

Bat exclusions are illegal during this maternity season to prevent young bats that cannot yet fly from being trapped inside structures and dying.

Florida is home to 13 resident bat species, including threatened species such as the Florida bonneted bat. Some bat species roost in artificial structures, including buildings and houses. Although it is illegal to harm or kill bats in Florida, guidelines have been developed allowing for the legal exclusion of bats outside of the maternity season.

Exclusion guidelines on how to remove bats from buildings can be found at MyFWC.com/Bats. Materials and methods to exclude bats can affect the success of that process. For more information on how to conduct a bat exclusion, watch this YouTube video: How to Get Bats Out of a Building. Further details on how to conduct a legal bat exclusion can be found at Bat Conservation International.

Bats are beneficial to people and are an important part of the ecosystem. The state’s native bats help keep insect populations under control, with the average bat eating hundreds of insects a night. In addition to the benefit of keeping mosquitoes and other insects at bay for residents enjoying the outdoors, the value of insect suppression by bats to U.S. agriculture has been estimated to be in the billions of dollars.

There are several ways that Florida residents and visitors can help bats:

• Preserve natural roost sites, including trees with cavities and peeling bark. Dead fronds left on palms can also provide roosting spots for bats.
• Put up a bat house.
• Report unusual bat behavior to: MyFWC.com/BatMortality.

Bats can carry rabies. Although infected bats may not become aggressive, like any other wild animal, they can bite to defend themselves if handled. Don’t touch or go near any wild animal, especially one that’s not acting normally. For more information about rabies, visit the Florida Department of Health website at FloridaHealth.gov.

FWC staff are working to learn more and share information about Florida’s bats. For more information on Florida’s bats, go to MyFWC.com/Bats. If you need assistance, contact your closest FWC Regional Office to speak with a regional wildlife assistance biologist for more information.

Florida’s four-month bat maternity season starts April 16 and lasts through Aug. 14. The Florida Fish and Wildlife Conservation Commission (FWC) is reminding the public that they cannot do exclusions to remove bats from buildings during this time when bats are giving birth and raising their young.
Florida is home to 13 species of native bats, including rare and threatened species. Many bats roost in natural sites such as trees with cavities and peeling bark. However, homeowners and building managers who need to exclude bats roosting in houses or other structures can do so as long as it is not done during maternity season.
In south Florida, additional precautions are needed to ensure Florida bonneted bats, an endangered species, are not roosting in a structure because they may give birth to pups outside of the April 16 to Aug. 14 bat maternity season.
The FWC provides guidelines on how to safely and effectively exclude bats without harming them or people. Go to MyFWC.com/Bats for more information.
“Maternity season begins in mid-April when groups of bats gather to give birth and raise young, and continues through mid-August when young bats are able to fly and feed themselves,” said Melissa Tucker of the FWC’s Species Conservation Planning Section. “Bats are beneficial to Florida, since they consume many insects, including pests that can significantly damage agricultural crops.”
FWC staff are working to learn more about Florida’s bats, including the Florida bonneted bat. Biologists are collaborating with University of Florida researchers on a study of a bonneted bat population on the FWC’s Fred C. Babcock-Cecil M. Webb Wildlife Management Area. FWC staff also are working with the Florida Forest Service to conserve bats at the FWC’s new Withlacoochee Caves Critical Wildlife Area.
