I love all creatures great and small. Except slugs in my garden.
Those slimy gastropods that not only gross me out, but they take large bites out of tender seedlings and shoots, devouring my precious plants. For that reason, all slugs must die, but in a natural way.
Here are 16 non-toxic (to humans) ways to kill garden slugs.
1. Cornmeal: Place a handful of cornmeal in a jar, and lay it on its side in the garden. Slugs will like the scent, slither in, and die.
2. Coffee Grounds: Spread coffee grounds around plants. Not only will the grounds damage slug bellies, but they will nourish your soil as well.
3. Egg Shells: Eggshell shards ringing your plants will stop slugs in their slimy tracks.
4. Dried Pine Needles: Dried pine needs make a great mulch that cuts slugs where they crawl. Spread it throughout the garden, and watch it rot into food for your soil.
5. Diatomaceous Earth: Place these granules of dead, microscopic creatures around plants to form a rough barrier that slugs can’t breach. Warning: The power can irritate eyes, so wear glasses or goggles, and don’t spread when it’s windy.
Dry Out or Dissolve Slugs
6. Salt: Salt dries up slugs eating your container plants. Ring pots with salt, making sure the salt doesn’t get near the drainage hole. I wouldn’t use salt in the garden, because it can harm soil and plants.
7. Seaweed: Seaweed is double trouble for slugs. Not only will the salt in seaweed harm slugs, but it dries into a rough layer that cuts slugs, too. Spread it around, but not touching, plants at least 3 inches high.
8. Vinegar: Is there anything vinegar isn’t good for? Mix equal parts vinegar and water, and spray the solution on slugs you’ve collected. It will dissolve the pests, but it can also harm plants. So isolate the slugs before you soak them in vinegar.
9. Coffee: Caffeine is a proven slug killer. Spray coffee on their soft bodies, and the neurotoxic caffeine destabilizes their heart rate.
10. Leftover Beer: I’d never open a can of Bud just for the slugs, but instead of pouring leftover brewski down the drain, I pour it in a cup or bowl with high sides and place it in a hole just above the surface of the soil. Slugs follow the scent of beer, fall into the beer pool, and drown.
11. Dog/Cat Kibble: Slugs like pet food. Use it to lure the mollusks into traps, like a clay pot with one edge slightly raised, or a turned-over, disposable pie tin with a couple of holes cut into its side. Set the trap at night when slugs come out to eat, and toss the prisoners to the wild birds in the morning.
More Slug Destruction Tips
12. Attract Birds: Birds love to chow down on slugs, so welcome these flyers with open arms. Place birdbaths, and hang feeders and nesting gourds in your garden to attract these slug terminators.
13. Water in the A.M.: Slugs love moisture and are most active at night. So water your garden in the morning, so the soil is dry and less inviting when the slugs come out to eat.
14. Pluck at Night: If you can stand touching the slimy things, take a flashlight out to the garden at night and pluck slugs from plants.
15. Human Hair: When you clean combs and brushes, collect the hair and spread it around plants. Slugs will tangle themselves in the hair and suffocate. Both slug and hair will decompose and feed your garden.
