This is an organically compliant snail/slug killing bait made from iron phosphate that derives from soil and is used in fertilizers. Combined with other snail and slug bait additives Sluggo Molluscicide attracts snails and slugs away from plants and other hiding places to ingest the active ingredient. Once Sluggo Molluscicide is ingested slugs and snails stop feeding and even though they are still visible around plants, they are no longer feeding on them. Slugs and snails will die in 3 to 6 days and will many time travel to hidden areas to die.
