Bats have an off season just like sports teams do. But rather than spending the off season conditioning for the upcoming calendar year, bats decide to either hibernate or migrate for the winter. So why do bats take the first flight out of the town once the cold weather starts to push back? The solution is chilly temperatures and meals! So to survive the subfreezing temperatures winter may bring with it, bats must hibernate or migrate.
Hibernation, Or torpor (controlled hypothermia), is the time when bats rest to conserve energy. It can last anywhere from several hours to a few months, depending on environmental conditions, species, and a lot of other factors. If the hibernacula temperatures are too warm, bats will exert too much energy, which risks their survival.
For they generally wake up every couple of weeks to readjust themselves based on the temperatures, and then they are back to resting. Hibernation saves them through times of food scarcity, however a few bats don’t even bother, and instead migrate, following warmer temperatures and bugs.
Some migrate south for the winter to follow the insects and head toward warm weather. So migration is temporary, and refers to the two migrations, to and from the location. Types of bats that migrate include silver-haired bats, eastern red bats, hoary bats, and most other tree-roosting bats.
Bats in the Attic
If you’re hearing odd scratching or squeaking noises coming from your ceilings or walls, 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 because they hide within the loft insulation, you can’t see them, therefore it is really hard to tell without the proper gear and a trained eye.
Have your attic scrutinized for roosting colonies by a licensed Raccoon Removal company that uses safe and humane procedures. They have the tools, training, and resources to manage your bat infestation, safely and efficiently. Many companies also provide bat cleanup and minor restoration for bat damages.
