We have been doing some garage work and had an opening into attic where a gray squirrel got in-my husband was able to scare him out and close up the hole but this squirrel has been chewing the wood to get back in and is hanging around the roof whenever we are outside..... I am concerned that maybe there are babies left inside but according to web, November is not a season for babies. Do squirrels try to get back to a "nest" this much in general or its possible there could be babies stuck in there?? Any advice appreciated!
