Effective Slug Control for Container Gardens

Copper paint on pots won't deter slugs—it lacks enough metallic copper. Instead, try these proven methods: sprinkle iron phosphate baits (like Sluggo) which are pet-safe; set out beer traps in saucers, refreshing every two days; or place a board on pebbles near pots as a daytime shelter, then scrape slugs into soapy water each afternoon. These tactics work far better than copper coatings.
