We had a "mouse hole" on our 1993 Holiday Rambler. It opened into a "false bottom in the closet in the bedroom. I thought that if I had problems, it would be "real easy to lift that panel and fix the kink in the cable"...
Well, we were in Alexandria, Louisiana at the time, and wasps, being what they are, decided to take up residence overnight. They chose that "warm, well protected cubbyhole"... The "tiny space around the cable" was the perfect entry for them..... Long story short, lifting that false panel to see what they'd done in there was a "significant event"... If you've never been in a 8'x8' room with thousands of angry wasps, you're in for a "thrilling ride" if it ever happens to you. They "set up housekeeping" in a matter of only a week. We'd used the trailer the week before, parked it to clean and repack, and when I got ready to hitch up the following Friday, that's when I was pushing the cable back into that cubbyhole and got stung the first time.
If you live anywhere wasps or yellowjackets also live...…..
