Moles

I have read on many RV forums and FB groups about the horrors of mice and rats getting into RVs. This as we all know can be downright scary. Also the damage they cause can be significant. The following is my fix. Hopefully it will help someone. I'm sorry for it being so long but it's quite detailed. Here goes. I don't think RV makers have but one drill bit, and it's a big one. They will drill a big hole for a small thermostat wire. Look inside your cabinets at the floor and you will find holes for plumbing and wiring. After raising our table and taking the cushions and wooden seat out to expose the converter, fuse box, and transfer switch I found 3 holes in the floor. All of them had plenty of space around the wires. There was steel wool packed in these holes. It might deter them but it will not stop them. I pulled out the steel wool and purchased two cans of Great Stuff expanding foam. It comes in two kinds, a crack filler and a cavity filler. You will need the cavity filler. Use this foam to fill all the holes. If you miss one they will find it. The mice and rats will not try to eat through the foam. Since it seals off all light and air they never see it as a path of entry to get in. Be sure to seal all holes under cabinets too. One of the more difficult holes to seal was by the gas furnace where the gas line came up. It was a stretch and hard to get to but it can be done. Depending on the way your RV is constructed you may be able to run some of the Great Stuff into the holes from the bottom too. Also don't forget your refrigerator, it has holes in the floor under it for the gas line and wiring. Many RVs have a drawer under the refrigerator. This will give you easy access. I leave them a treat in the storage under the floor. It's a cake looking chunk of poison. I don't think you can keep them out of the storage areas. There is just too many cracks and crevices they can enter in. In my case in our motorhome the AC power cord is wired direct and comes up thru the bottom of the storage floor. All the mice have to do is climb up the cord and come in the storage area where I have a nice little treat for them. As a final note, if you seal the holes and the critters still get in you have missed a hole somewhere. Find it and seal it and you won't be bothered again.
