Bugs in the RV, were are they coming from!

We had this same problem at our home in Idaho. Found out these are cluster flies. The flies congregate on a warm wall and find their way in no matter how well your home or rv is sealed up. We found that spraying the wall with Cutter 32 fl. oz. Concentrate Backyard Bug Control Spray fro Home Depot, when it started to turn cold and the flies sought out the warmth of the wall, did the trick. This kills the flies before they crawl in. Google cluster fly for more info.

Have not had any bug or rodent issues so far. As a preventative, i have stuffed any cracks or possible entry points with steel wool. The soapless kind. Rodents hate that stuff and wont chew through it. As for bugs, except for the occasional mosquito that might get in, I have been fortunate and not had any issues. I have used the bug bombs before for out buildings and they worked.
