Scheduling Bat Exclusion Around Hibernation
New York is home to six species of cave bats who stay in the area to hibernate during the winter. Of the six, the big brown bat often uses man made structures for its winter hibernation. The bats enter torpor – a state of lowered temperature and heart rate – when temperatures cool in mid-October and come out of it around April. During this time, they use their fat reserves to sustain themselves. Exclusion in winter months is ineffective since the bats are not leaving their roosts nightly to hunt. Additionally, disturbing hibernating bats is extremely harmful as each time a bat comes out of torpor uses up vital energy reserves. Too many disturbances can result in death before bats can resume hunting insects in the spring.
Understanding Types of Bats in Your Home
Of New York’s nine bat species, there are 6 that are most often an issue for homeowners. These are called cave bats as they prefer to roost in groups in sheltered spaces like caves and mines out in nature. But when they dwell in urban areas, attics, sheds, walls, chimneys, bridges, and other crevices in man-
made structures provide their shelter. The most common cave bat invaders in homes are:
- Big Brown Bat
- Little Brown Bat
- Northern Long Eared Bats
The other 3 cave bats can also make their homes in houses. These are the Indiana bat, eastern small- footed bat, and tricolor bat. Depending on the species, bat colonies can contain anywhere from a few bats to thousands, which can result in a messy and hazardous situation wherever the bats are living.
The big brown bat is the only one that will hibernate in homes through the winter. The others will leave their roost for a more natural location. The Indiana bat, northern long eared bat, and eastern small- footed bat are protected under NY state and federal law as endangered or threatened species at risk of becoming endangered. Attempting to remove these three species outside of the permitted exclusion schedule, or harming them at any time of the year, can result in costly penalties.
Working with a team that is knowledgeable about local bat species is extremely important for exclusion because of the risks with individual species. NY and NJ Animal Control can identify the species present in your home and guide the exclusion timeline in a way that is safe and legal.
