Bats have an off period just like sports teams do. But instead spending the off season conditioning for the upcoming year, bats choose to either hibernate or migrate to 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 chilly temperatures and food! So as to survive the subfreezing temperatures winter may bring with it, bats need to hibernate or migrate.
It may last anywhere from several hours to a couple months, depending on environmental conditions, species, and several other aspects. If the hibernacula temperatures are too hot, bats will exert too much energy, which dangers their survival. To the contrary, if hibernacula temperatures are too cold, bats will simply freeze to death.
For this reason, bats find dark, warm, cozy areas to hibernate in, like attics, crawl spaces, caves, mines, and bat houses. They generally wake up every couple of weeks to readjust their rankings based on the temperatures, and then they’re back to resting. Hibernation saves them through times of food scarcity, but some bats do not even bother, and instead migrate, after warmer temperatures and germs.
Some migrate south for winter to follow the insects and mind toward warm weather. So migration is temporary, and refers to the two migrations, to and from a place. Types of bats that migrate include silver-haired bats, eastern red bats, hoary bats, as well as most other tree-roosting bats.
If you are hearing odd scratching or squeaking noises coming out of your walls or ceilings, you might have some hibernating bats in the attic. When the temperatures change, they will adjust their positions to secure cooler or warmer during hibernation. This happens only once every few weeks; and since they hide within the loft insulation, you can’t see them, therefore it is hard to tell without the proper equipment and a trained eye.
Have your attic scrutinized for roosting colonies with a certified bat removal firm that uses safe and humane procedures. They have the tools, training, and resources to control your bat infestation, safely and economically. Many companies even offer bat cleanup and minor recovery for bat damages.
