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?
Those holes are open invitations to mice, roaches, ants, etc. I would suggest loosely stuffing a little steel wool in the hole, then giving each a shot of spray foam to seal. Easily enough gouged out if you ever need to reopen to make repairs, but not possible for the varmints to chew through.
