I'd like to use the spray foam but I read that ants can even create a nest in the foam.
About the cauliking, since the hole is little and there isn't much space, I can't "introduce" in that space a caulking gun, and I'm also worried that caulking, since "it's dense", would simply "close the hole on the surface".
I really need to put something "inside" the hole that can fill it and THEN use caulk to seal the top.
I started to use granular poison and gel outside the hole, but I think that the entire building (9 floors, 1950s concrete building) is like "infested" so it seems a nevereding battle since they keep coming back after a while.
If I close it with a simple trim piece they will continue to climb and go under the floor. I need to seal it deeply.
