Bats have an off season only like sports teams do. But rather spending the off season conditioning for the upcoming calendar year, bats decide to hibernate or migrate to the winter. So why is it that people take the first flight out of the town when the cold weather begins to push back? The answer is chilly temperatures and meals! In order to survive the subfreezing temperatures winter may bring with it, bats need to hibernate or migrate.
It may last anywhere from a few hours to a few months, depending on environmental conditions, species, and a lot of other aspects. If the hibernacula temperatures are too warm, bats will apply too much energy, which risks their survival. To the contrary, if hibernacula temperatures are too cold, bats will simply freeze to death.
Because of this, bats locate dark, warm, cozy areas to hibernate in, such as attics, crawl spaces, caves, mines, and bat houses. They usually wake up every few weeks to readjust their positions based on the temperatures, and then they’re back to resting. Hibernation saves them through times of food scarcity, however some bats don’t even bother, and instead migrate, after warmer temperatures and germs.
Some migrate south for winter to follow along with the insects and mind toward warm weather. But once the spring is back and food is abundant, they head back home again. So migration is temporary, and refers to both migrations, to and in the place. Types of bats that migrate include silver-haired bats, eastern red bats, hoary bats, and most other tree-roosting bats.
If you are hearing odd scratching or squeaking noises coming out of your walls or ceilings, you may have some hibernating bats in the attic. When the temperatures change, they will fix their positions to secure warmer or cooler during hibernation. This happens only once every few weeks; and because they hide inside the loft insulation, you can’t see them, therefore it’s really hard to tell without the proper gear and a trained eye.
Have your attic inspected for roosting colonies by a licensed bat removal company which utilizes safe and humane procedures. They have the resources, training, and resources to control your bat infestation, safely and efficiently. Many companies even offer bat cleanup and minor restoration for bat damages.
