I've got four customers who border each other who share some serious mole problems. They total approx 3/4 acre and there are 7 mole tunnels on the property. I bought a trap and followed the directions (locate active tunnel, depress tunnel entrance, set trap and wait for the mole to tunnel out), but I am not having any luck. I'm thinking that maybe the trap is scaring them away or something. I've been trying all weekend and haven't caught one. I've been setting the traps and waiting about 8 hrs or so. No success. All the locations where i've set the traps appear to be inactive since setting the trap. Any advice for success?
