I don't remember the brand name of the repellent I used to use, I used it for moles quite effectively and I've heard that the same repellent is effective for gophers. It's a castor oil mix with water basically. You spray it onto the soil and the smell bothers them enough that they will leave. It doesn't smell bad to us, though, sort of like elmer's glue. One of the links says it works by coating the grubs moles eat with the castor oil and making them taste bad.

I found they'd come back after a few months, then I'd spray the ground again, and sure enough they'd move out.

I've searched a bit just now looking for the product I used to use, didn't find it in a short search. But I did see some others that look like the same thing, more or less. Here are some links:

It's worth a try, before using traps. I know first hand it works for moles, I have only heard that it repels gophers, too. One of the above links says it works on gophers...
