Plugging Small/Hidden hole in drywall
So I have an old crappy house with an old crappy laundry room, and in getting a new washing machine, I can see that there's about a 2 by 3 inch hole in the sheetrock on the bottom left corner of the wall, where I can see the studs/framing. I would like to put in minimal effort, but also prevent rodents, bugs, and airflow through that hole.
Ideally I would cut more wall, square it up, do a california patch and put joint compound all over it. But this is behind a washing machine, and I'll never look at it. Is it a bad idea to get some sort of expanding foam and just squirt it inside the hole to create a seal? I don't know how hard it is to cut out that kind of foam if I wanted to fix this in the future if/when I sell the house.

If you don't want to do a full patch right now, pack the hole tight with steel wool.

There isn't just rampant electricity running thru your walls, and if there is an electrical line where the hole is. He has bigger problems because rodents and bugs have likely chewed the shit out of it and it will need to be replaced and relocated.
