Hang a Bag of Mothballs
Mothball haters include rodents and insects (duh!), so consider putting some of the smelly orbs in your vegetable garden. Just don’t let them touch the soil, or the toxic chemicals mothballs contain (usually naphthalene or dichlorobenzene) could contaminate it. (If you think you can simply place mothballs on lids, tiles, or other flat surfaces to keep them off the ground, think again. In no time at all, wind and garden invaders will knock them off.) For safety’s sake, put a few mothballs in small mesh bags and hang them from a cornstalk or a beanpole trellis.
