hi,
i have standard hardwood floors and "quarter round" "molding". the house is from 1946 and their are some gaps under the quarter round that let ants come into our house. i am wondering, if i take all the quarter round out, is there some type of foam or other product i can use to fill in the gap from the edge of the wood floors to the wall. then i could reinstall the quarter round, and even if it wasn't installed perfectly, ants couldn't come up into the house anymore.
ideas? is there some standard way to do this "filling"?
