We have an ongoing gopher problem around our place. And they are hard to snag. Don't like to kill the critters, but what can you do? Pretty soon you're overrun. Don't see any alternative. Have come up with a way that seems to get 'em better than anything else I've tried: look at the picture. Using a 4" plastic pipe you put the McAbee brand trap right up to the edge (the trap is inside the pipe). Dig out the mound until you have "open tunnel." Shove that pipe into the tunnel and there you go. Don't know this why it works better or maybe it doesn't work better but it definately is easier to get the trap out afterwards when the smart gopher piles dirt on the trap then takes off leaving you to pull out a dirt empacted trap.
