They may look cute, but there’s nothing cute about the damage furry little critters can do to your garden. So it’s a good thing that practically all four-legged pests – including gophers, groundhogs, skunks, squirrels, and roaming pets – will flee from the scent of ammonia. Just soak rags in the stuff, put them in old panty hose toes, and hang them in the areas you want to protect. If there’s no hanging space, pour the ammonia into wide-necked bottles (like the kind juice comes in), and bury them up to the rims here and there throughout your garden.
