We've been in a camping spot for about a week now and we are having really bad problems with bugs getting in our camper. I've been camping in PuPs for over 20 years and never seen anything like this. Particularly bad this year are the earwigs and Gypsy Moth caterpillars. I'm not talking a few, I'm talking like several per day. Any tips/ideas on how to further bug proof my PuP? I know and expect some bugs in here, but like I said, i've never seen anything like this in 20 years.
