I don’t know but admire your humor..

Get a Chihuahua!

Go to the farm supply store & pick you up a can of Big Cat Urine. It comes in a can like spray paint & you just spray the outside perimeter of your house. If they think a feline is nearby, they get scared. You could also Live-Trap them & take'em off to a safe area & release them before spraying around your house. After a few days, you can spray a little further out into the yard & repeat after another 2-3 days until you reach the perimeter of your entire yard. Note ~ After a heavy rain, you will havta respray because the rain will dilute the spray. This process will gently run them away from the house & off your property. If you've got a house cat or outdoor cat as a pet, this spray will make them defensive & upset.

Are you sure they are gophers? Sounds more like the behavior of a rock chuck.

My Chihuahua chases them but my cat brings them home (alive) as gifts... Good Luck😀
