Facts about Slugs and Snails
Slugs and snails can cause huge damage in gardens and are capable
of consuming several times their own body weight in a very short
period of time.
Favourite plants include hostas, marigolds, dahlias, tulips, lavender
and snapdragons but they will quickly devour other succulent foliage
too.
Slugs and snails are gastropods. This means "stomach-foot" and
refers to their one muscular foot. They need moisture to move,
and excrete a slimy fluid from glands on the foot that dries to
become the silvery trails that are evidence of infestation.
Slugs and snails prefer cool, moist conditions and tend to feed
at night, but they may be active during the day if the conditions
are right.
They will take cover in hot, dry weather and are able to go without
food for long periods of time. However, prolonged dry weather may
kill up to 90 per cent of eggs and young per year.
Mature slugs and snails are hermaphrodites, containing both male
and female reproductive organs.
They lay 20-100 eggs several times a year in sticky white blobs
visible in shady parts of the garden.
The young reach sexual maturity after six or seven months. |
