Never had roaches in an RV before, but living in the south and our property bordering on wetlands we get the occasional "palmetto" bug. Advion gel works better than anything I have ever tried. You can buy it on amazon. It's not a spray or kill on contact. It's a food that they ingest, and it will eventually kill all of them. Works in about 24-48 hours. Safe for pets (only affects things with an exoskeleton).
I'll try that.
Does it do any good to fill the holes in the floor where the plumbing and wiring comes in from the basement? There are holes in the toilet area, galley, powder room and washing machine area. Plus others I've never seem?
