Sealing plumbing & electrical holes

Anybody have a good way to seal the electrical and plumbing holes in a travel trailer?something other than the spray foam. We just got back from a weekend at a State Park where the sites were infested with ants. They were coming in our rv from all of the different holes on the floor.

Maybe steel wool ? Do you not like the aesthetics of spray foam ?

How about this. It's spray foam specifically designed to block pests.

You will never seal all the holes. Once you try, they will open up once you travel again.

Sprinkle boric acid over the area before you park.

No, its not that, I'm just not sure how you would keep it in place. With it being a hole, I would think the foam would tend to flow down into the hole. There probably would have to be some sort of barrier to keep it in place until it dries.

The foam is very thick, and extremely sticky....it will stay in place. It also expands as it cures completely filling all crevices.

I've used Great Stuff (the regular) on at least 3 RVs and have to say that it stays where you put it - many miles of travel doesn't break it down. A big wiring or plumbing hole, use some steel wool first so you don't waste a lot of the foam, then the Great Stuff. I've never seen the no pest version but 'assume' that it will do the same job and for a couple bucks more for a can.

If you simply want to tighten things up, put backer rod in the area to fill the gaps then spray the foam. Remember that the foam comes in expanding and non-expanding. The backer rod is found in the insulation department of HD or Lowe's. Just ask for it

One of our favorite parks has a argentine ant (invasive species) problem. The ants are harmless BUT they get everywhere. The Corp of engineers suggest putting kitchen cleanser around the touch points that hit the ground. We have found it very effective to keep ants out. Also they suggest putting vasilene(sp) about an inch long on the water hose and power cord.

Great suggestions. If you visit So TX, around Hitchcock, watch out for Rasberry ants (https://en.wikipedia.org/wiki/Rasberry_crazy_ant). They get into the electrical components of homes and RVs. These little buggers can cause allot of damage even though they don't bite.

Will keep your suggestion in mind. Thanks.

Happy trails,
Rick Y

I drilled using a hole saw 1/8" thick by 2" 4" and 6" circles of poly propelene cut one side open so it can insert it over the tubing and pipes. These are screwed on using stainless steel screws. The center hole can be drilled to an exact fit.
