A groundhog dug a tunnel into my garden last year, I filled it in last
fall but he's just reopened it again. I've bought some Havahart Critter
Ridder which is basically a hot pepper powder. Has anyone used this
stuff? Does it work?. There were a couple of other choices for groundhog
repellents that had a very different formulations, does anyone have any
opinions on repellents in general?
