Bats must find a winter roost where they can maintain a body temperature at a few degrees above freezing. Choosing the perfect location to hibernate can be critical for their survival. If the roost temperature goes below zero they will freeze to death. And if temperatures get too warm they will use up their fat reserves too quickly and starve to death.
In order for the bats to stay in the hibernating state, called Torpor, they need to maintain their body temperature at 3 degrees Celsius. When it gets too warm or too cold outside, they tend to move within the walls of the house to find a location that is 3 degrees Celsius. Due to the cold snap in temperature that we had in Toronto last week, this bat was able to stay in it’s hibernating state and ended up finding its way into the living space of the home while looking for warmer temperatures.
Finding a bat inside your house is typically a sign that there is a colony of bats living inside the attic. When baby bats try to venture through the entry hole to the outside, they sometimes loose their footing and find themselves inside the wall space and end up popping out in an unfinished basement.
Please note: If a bat is found inside a house during the winter months do not release it outside, it will not survive. Call a local wildlife rehabilitator and they will care for it until the spring. Saving the life of every single bat is critical as their numbers are rapidly declining. In fact, the little brown bat is now on Ontario's Ministry of Natural Resources and Forestry's Endangered List.
