If a bat appears in the house during a prolonged deep freeze, you should contact a local wildlife rehabilitator who is licensed to care for rabies-vector species and see if they are able to take the bat. Bats should not be kept contained like this for long as they will quickly dehydrate in warm temperatures in the house. Hibernation is an extended period of deep sleep, also known as torpor, that allows animals to survive the harsh conditions of cold winters. This isn’t only due to their nocturnal nature but because they hibernate through our long, cold winter months. This is of particular importance as the cold-adapted fungus, Pseudogymnoascus destructans, which causes the fatal bat disease white-nose syndrome (WNS), continues to spread into southern United States. You’re not likely to see many bats through the festive season. If temperatures are well below freezing, you can keep the bat in a box overnight until temperatures rise in the day, and release the bat at that time. Few studies have described winter microclimate selection by bats in the southern United States. They are primarily nocturnal, though they also forage in the early evening and early. ![]() Bats are relatively long-lived, some surviving up to 20 or even 30 years in the wild. Of the 17 species that occur in North Carolina, three are federally endangered and one is federally threatened. If temperatures are above freezing, the bat can be released outside and should be able to find a new place to hibernate -under some bark, a hole in a tree, hopefully not back in the attic! Bats hibernate to preserve energy during winter months, enabling them to survive periods of prolonged cold and lack of food. Bats represent one-quarter of all mammal species worldwide. While wearing gloves, place a container over the perched bat and and scoop it into the container. It is natural for bats to awake periodically throughout the winter to move their muscles and. It is at this time that they can find their way out of the crawl space and into the house. Coming out of hibernation is greatly dependent upon temperature. ![]() Bats awaken occasionally during winter to move around a bit, or to adjust to changing temperatures if their spot is suddenly too warm or cold. If you have a "winter bat" it's probably a big brown bat. They are more solitary than little brown bats and more likely to hibernate in an attic, crawl space, or wall. Big brown bats, Eptesicus fuscus, have a body size of 3.9-5.1 inches and an 11-13 inch wingspan. Both the little brown and big brown bat can end up in the house in winter, but it is much more likely for the bat to be a big brown bat.
