It might sound strange, but if you hear noises at night in the attic it may not be your imagination. Maybe those bumps in the night might be coming from inside your attic. Even the smallest of holes allow mice and insects such as honeybees access into your home. I always suggest that you do periodic checks of your home especially the attic to basically keep an eye out for trouble makers. Birds and even larger animals can gain access into crawlspaces & attics and sometimes it is a real pain to get rid of them. Honeybee are always on the search here in Arizona for a new place to live, our Honeybees often swarm in Spring and Fall since we have a somewhat higher temperature throughout the year. If you notice bees going into your home use extreme caution as they may be very dangerous. Once you have made them MAD, you can’t take it back. They can stay agitated for 8+ hours, they can sting dogs, neighbors and children.
