The Need to Hibernate

Bats are tiny creatures that expend a lot of energy flying. When temperatures drop and their favorite insect food sources become scarce, bats must combat the loss of available energy by hibernating, or slowing down their bodily functions.

While an active bat’s heart rate might fall anywhere between 30 and 40 beats per minute, a hibernating bat’s heartbeat rests around 10 beats per minute. Body temperatures and breathing rates also fall considerably in order to conserve energy.

Though not all species participate, most bats found in our service area must hibernate due to the harsh winter conditions that span from November to April.

Locations Bats Hibernate

Favored hibernation locations include:

  • The depths of caves
  • Unused buildings
  • Abandoned mines
  • Anywhere else temperatures remain above freezing and humidity is high.

Bats also target locations where they are unlikely to be disturbed. Since they lose a significant amount of their fat reserves during hibernation, being jarred into activity by nearby humans can prove fatal.

For this reason, bats do not typically choose attics or other areas of homes as overwintering sites.

Do Bats Hibernate in Homes?

Despite the unlikelihood of bats hibernating inside homes, individuals or small groups of the mammals may occupy rarely used sheds or barns to overwinter.

In the event bats are found in or around private properties, calling professional wildlife services is recommended.

Attempting to handle bats can lead to injuries or the transfer of diseases, and trained specialists have the tools and knowledge required to diffuse infestation situations in the safest manner possible.
