If slugs were houseguests, you'd never want them to visit again. Once these slimy pests settle into your garden, they'll help themselves to your homegrown veggies, destroy seedlings, and munch on your plants' leaves until they look like swiss cheese. To get rid of them for good, skip the toxic pellets and opt for a natural alternative like beer or oatmeal instead. To make your own trap, pour some beer in a shallow tin like a tuna can. Slugs love the smell of a cold brew, so you'll have your garden back in no time.
