As Bat Week kicks off across North America, state officials are reminding New Yorkers to stay out of caves and mines this fall and winter to help protect the state’s vulnerable bat populations.
The New York State Department of Environmental Conservation (DEC) issued the reminder ahead of Bat Week, observed annually from October 24–31, as part of a larger effort to raise awareness about the crucial role bats play in the environment.
“Disturbing bats from their hibernation patterns can cause unnecessary harm to their systems and recovery,” DEC Commissioner Amanda Lefton said in a statement. “When outdoors this time of year, please do not venture into caves and move away quietly to ensure bats can remain in their natural hibernation patterns.”
There are nine species of bats in New York, and six of them hibernate in caves or mines over the winter. All are insect-eaters that help control pests, reduce the need for pesticides, and even fight off invasive species.
But human disturbance — especially during hibernation — can be deadly. If bats are startled awake, they burn through their fat reserves too quickly and may not survive until spring. Since the arrival of white-nose syndrome in 2007, an estimated 90% of the state’s bat population has been wiped out at known hibernation sites.
DEC officials say that disturbing bats or entering known hibernation sites from October through April could result in prosecution. They’re asking the public to observe all posted signs and report any illegal activity.
The agency also offered simple ways to support bat conservation at home:
- Limit tree removal to winter months, when bats are not nesting or raising pups.
- Plant pollinator gardens to help attract insects, which bats feed on.
- Install bat boxes to provide safe roosting spots.
- Use certified wildlife professionals to safely remove bats from buildings.
There’s even some good news — researchers have seen signs of a slow recovery in little brown bat populations across the state. However, other species like the Northern long-eared bat remain in steep decline.
