Got a Woodchuck problem?
Try dumping well-used cat litter down their holes; to them it smells like a Big Cat predator, they don't know it's just "Mittens" the adorable declawed house pet. By nightfall mom, dad, and the kids will be hitting the dusty trail. Make sure it is "well-used" cat litter; and be sure to put it in all entrances and exits. If the woodchucks relocate close by, reapply the litter in their new holes; they'll get a hint.
