Molluscicides, also known as snail baits and snail pellets, are pesticides against molluscs, which are usually used in agriculture or gardening to control slugs and snails that can damage crops by feeding on them.
Molluscicide are usually belonging to three main classes:
Metal salt-based molluscicides are not toxic to higher animals while metaldehyde-based and especially acetylcholinesterase inhibitor-based products are highly toxic and have resulted in many deaths of pets and humans. Some products contain a bittering agent that reduces but does not eliminate the risk of accidental poisoning. Anticholinergic drugs such as atropine can be used as an antidote for acetylcholinesterase inhibitor poisoning. There is no antidote for metaldehyde, the treatment is symptomatic.
