Bugs in the trailer
Insects comming in between the upper and lower section's are rare, and usuly caused by not keeping up the maintanace of ajusting cables. I find the worst problems of bugs come from the porch light so close to the entry door. We try not to use the porch light to often. Using awning lights work better as the bugs are not right by the door. Aints are a bigger problem than flying bugs. In Louisiana we know going in we need to spray for aints and bugs of all kinds, our mosquitos are so large we refer to them as our state bird. I find if you keep a fan running under the awning, blowing down the trailer side will keeps all bugs away from the door and helps keep misquitos out of the trailer.
