Do Bats Have an Off Season?

No Comments


Bats have an off season just like sports teams do. However, instead spending the off season conditioning for the upcoming year, bats choose to either hibernate or migrate for the winter. So why is it that bats take the first flight out of town when the cold weather begins to push back? The solution is cold temperatures and meals! In order to survive the subfreezing temperatures winter can bring with it, bats need to hibernate or migrate.

Hibernation, or torpor (regulated hypothermia), is the time when bats rest to preserve energy. It may last anywhere from a few hours to a couple months, depending on environmental conditions, species, and several other factors. In case the hibernation temperatures are too hot, bats will apply too much energy, which dangers their survival. To the contrary, if hibernation temperatures are too cold, bats will simply freeze to death.

They generally wake up every few weeks to readjust their positions dependent on the temperatures, and then they are back to resting. Hibernation saves them through times of food scarcity, but a few bats don’t even bother, and instead migrate, following warmer temperatures and bugs.


Some migrate south for the winter to follow¬† insects and warm weather. When the spring is back and food is abundant, they return home again. So migration is temporary, and describes both migrations, to and from the location. Types of bats that migrate include silver-haired bats, eastern red bats, hoary bats, as well as most other tree-roosting bats. The food they’re after includes termites, beetles, mosquitoes, and flies.

If you are hearing strange scratching or squeaking noises coming out of the walls or ceilings, you might have some hibernating bats in the attic. When the temperatures change, they will adjust their positions to get warmer or cooler during hibernation. This occurs only once every few weeks; and since they hide within the attic insulation, you can’t see them, so it’s really hard to tell without the proper equipment and a trained eye.

Have your attic inspected for roosting colonies by a certified Wildlife Control Service Fort Lauderdale Company which uses safe and humane methods. They have the tools, training, and tools to handle your bat infestation, safely and efficiently. Many companies also provide bat cleanup and minor restoration for bat damages.
