Elaine, we had moles the first year we lived in the house and Vince would send smoke bombs to get them out cause they would come out from another hole...
Well these moles were so smart that they would push the smoke bombs out and push them away from the holes...
Right now it's winter so we don't see them but come spring and summer we know they are still there
cause they come out at night and make little holes in our grass looking for bugs...
