During the love bug season of May and September, I try to wrap clear Road Wrap on the front of our 5th wheel. Then when we get home I can pull the wrap off and put it and the bugs in the trash. On the truck it is a matter of scrubbing them off with Spray 9 cleaner, the best product I have found. We got in to some of the love bugs the last week of April on our way back from Disney in Orlando. I wasn't expecting them that early so got to scrub both the trailer and the truck.
A guy at the campground at Disney thought I was pullin his leg when I told him he needed to wash his rig before the bugs damaged his paint. Not sure I was ever able to convince him I was serious. He was an out of state person.
