These pests love the soft, juicy seedlings of many plants and will seek them out.Snail

A whole row of newly germinated cabbages or a pot full of young lettuce can mysteriously disappear overnight if a large snail finds them.

Problems mostly occur in the garden but slugs, in particular, also enjoy conditions in the greenhouse and can cause just as much damage there.

Various chemical baits are available but must be used with care as many are toxic to pets and other animals. Traps, often containing diluted beer and set slightly above soil level, will drown or collect many slugs which can then be disposed of.
