Woodworm
Insect infestation is at the root of woodworm. The most common beetle is the 'Anobium Punctatum'.
It lives in three year cycles. The first six to eight weeks it is an egg emerging as lavae which go on to feed on the timber for the next three years. Eventually the' lavae purpates' and changes to an adult beetle which then eats its way through the surface to fly off and find a mate, before the process begins again.
Woodworm is treated by spraying with a water based insecticide. This coats the surface of the timbers and produces a layer of residual fluid which will remain in place to ensure that any woodworm eating their way out of the timber will become sterile and unable to breed.
