Up until now I've been trying to pee down his hole with chemicals, such as hydrochloric acid,
pool bleach, industrial ammonia, etc.

That's *not* a gopher hole; it's waaaaaaay too small. You have chipmunks.

Get a rat trap, and bait it with raisins. If you have pets or small children, make sure they can't
reach it: a rat trap will crush a dog's or cat's paw, or a child's hand.
