Bat in Attic in Winter and Pest Control Guy

 

Bat in our attic in February. I thought they migrated somewhere in Winter.

Saturday February 22, 2025,  I enter our attic with idea of putting a screen over the opening beneath the roof vent so as to prevent possibility of bats entering via that. However, I discovered a bat hanging on a roof rafter. His fur seemed to have a patch of grey or white hair. My research has lead me to believe the bats in our area migrate to a warmer clime in the Fall and return in Spring. Not this one. So I called a pest control guy and he came over this morning (Thursday February 27). Now the bat was nowhere to be seen, but we were not prepared to move through the attic to locate it either. The past week or 10 days the temps have been below zero here, reaching 10 below one night. Of course the attic would  warmer and the bat must be hibernating n our attic. BUT, days later it wasn't in view. I learned that bats will arouse every couple weeks during hibernation and move around.

This close up of bat was cropped from the wider view photo above.

The bat guy said he could find NO evidence of bat activity in our attic. If not for the photos he wouldn't believe there was ever a bat in there.  

One more thing. I have read in many different web sites that bat's do not stay in attics because they are too hot in summer and too cold in winter. Instead they go down in the walls. Sometimes these walls will lead into the basement and bats find themselves there.
