They pull entire young plants underground. One day you have a nice tomato plant growing, the next day "poof" it just disappears. We do raised bed gardening because of the gophers and lined each bed with wire mesh. But somehow one found a way into our onion bed this year and ate every single onion, save for about 10 I pulled when they were about the size of golf balls. We tried flushing, bombing, traps, deterrent smells. Nothing worked. I didn't want to use poison in a food crop or on the risk of my dogs or chickens finding and it the carcass. Every time I see a gopher snake in the yard I do a happy dance.
