Steve,
Let me pass on some good info I sent to Magilla Gorilla last year.
When I moved to So Fla 6 years ago the moles/gophers created a subway system in the yard.
The literature on control says that elimination is the only way to win. Found a product that really works and is available at HD or Lowes. It’s called "Tomcat Mole Killer". Comes in 2 forms now - earthworm and grub. You open an active tunnel and insert one of these jelly worms/grubs inside and carefully cover it up without crushing the tunnel.
I use a 12" pair of curved forceps for inserting the Tomcat worms in the tunnel. Gets the thing in there and disturbs the tunnel ceiling the least. One worm per 12' of tunnel. I don't know if my critters are the same as yours, but if they drag the thing back to the nest for the pups results should be dramatic. And it's alot cheaper and less work than chickenwire.
It took 6 to 8 applications the first time I used it. One day, 2 months after stopping the baiting, I noticed all tunnels had collapsed. The tunnels showed up 2 years later but that's cause I have 2 vacant lots on each side of me.

Was worried about the dog - labradors love to dig, right? She ignored the baits.
Gotta say again - this stuff really works!!!
