Scotts® EcoSense® Slug B Gon® Slug and Snail Bait is a unique product containing ferric phosphate, which is a compound commonly found in soils, in a specially formulated bait. Any uneaten bait will degrade and become part of the soil in your garden. After ingesting this bait (even in small amounts) slugs and snails cease feeding, which provides immediate protection to plants. Affected slugs and snails die within three to six days. Dead slugs and snails may not be visible as they often crawl away to secluded places to die. Plant protection will be observed in the dramatic decrease in plant damage.
