THE HOUSE LONGHORN BEETLE is principally found in roof timbers where it attacks the sapwood of exclusively softwood timbers often resulting in structural weakness. Holes and tunnels of this beetle are significantly larger than the furniture beetle. Treatment for this beetle is highly specialist and Building Societies will insist on a specialist company if structural timber has been affected. This large insect is mainly found in Southern England.
THE COMMON FURNITURE BEETLE. The Common Furniture Beetle is responsible for 70% of all woodworm damage in the UK. This beetle attacks softwoods and hardwoods. All woodworm damage can be attributed to woodworm larvae tunneling out from the wood. This can seriously damage the wood and may lead to timbers being renewed!
THE DEATHWATCH BEETLE attacks large hardwood timbers such as Elm and Oak. It can start from hardwoods like these may move across to neighbouring softwoods. It prefers very damp conditions and even better when there is some kind of fungal decay or "wet rot" in the timbers. The pest needs these conditions to develop rapidly. Treatment can be in the form of a paste, spray on application or paint on preservative.
