Slugs can decimate a garden overnight. A single slug can eat twice its body weight in plant tissue every day. Here are 7 proven organic methods.
## Method 1: Beer Traps
- Bury shallow containers at soil level
- Fill with stale beer
- Slugs crawl in and drown
- Empty every 2-3 days
## Method 2: Copper Barriers
- Creates mild electric shock on contact
- Apply copper tape around pot rims and raised beds
- Works for 2-3 seasons
## Method 3: Diatomaceous Earth
- Microscopic sharp edges cut slug bodies
- 1-inch band around plants
- Reapply after rain
- Use food-grade DE only
## Method 4: Eggshell Barriers
- Crush into jagged pieces
- 2-inch ring around each plant
- Coffee grounds and wood ash also work
## Method 5: Hand-Picking
- Night patrol with flashlight
- Drop in soapy water
- 15 min/night reduces populations 50% in a week
## Method 6: Natural Predators
- Birds: install bird baths and perches
- Ground beetles: leave undisturbed habitat
- Frogs: add a small pond
- Nematodes: apply Phasmarhabditis hermaphrodita
## Method 7: Iron Phosphate Baits
- OMRI-listed for organic gardening
- Slugs stop feeding within hours
