The active ingredient in Sluggo is iron phosphate which is an organic compound that breaks down into fertilizer. Sluggo can also be used in vegetable and berry gardens up to the day of harvest. Used the same as the other bait materials. Simply scatter in the evening where snails and slugs feed. Once they have eaten the bait they crawl back under the plants to die. Slower acting than metaldeheyde but active on the soil surface longer. OMRI listed.
