Q: My backyard got invaded by gophers (or someone who enjoys making holes). I'm worrying that I might injure myself in the holes. I have tried setting traps, but have been unsuccessful. I heard some snakes can kill gophers, but I'm also aware not to release invasive creatures. What do you recommend?
