Can of foam---where to spray?

It will save as long as you clean the nozzle.

Not sure on the fridge idea, but put some steel wool in the holes before you spray. Mice will chew through the foam if there is no steel wool.

I wouldn’t use that or any other insulation on the back of the fridge. It works by heating things up and needs to be able to shed that heat out the back. Insulate the wrong thing and you will kill it.

Where my water connections came into the trailer to the water pump and then through the floor to the tank, it came through the wall through a very flimsy plastic insert. Normally this was OK but as it got colder and if the water was cold it would condense. I fixed this by spraying foam on the inside of the plastic insert and no more problems. It might work for you as well.

Curly Kates or similar is even better than steel wool.

WARNING! Do NOT put steel wool in a hole with a wire going through it. Did it in my S&B and the mouse started chewing the wire insulation to get around the steel wool and was down to the bare wire. It was in a kitchen overhead cabinet, and when I opened the door I saw a flash of light as the wire was shorted out by the steel wool. Luckily, I avoided a fire. I removed the steel wool (after turning off the breaker) and filled the hole with spray foam.
