The Wood Boring Weevil
The most common type of woodworm is the wood boring weevil (Pentarthrum Huttoni), which is found in infested in decayed softwoods and hardwoods in damp conditions all year long, it can cause significant structural damage to timber. Damage is secondary to fungal decay. No insecticide treatment is required as only the source of dampness needs to be rectified and decayed timber replaced.
The Common Furniture Beetle (Anobium Punctatum)
This beetle can fly and can also cause significant structural damage to timber. It’s habitat is general softwoods and European hardwoods, solid timber sapwood only affected, unless wood rot present, when it may be found in heartwood also. It is frequently found in constructional timbers particularly around loft access, timbers in contact with solid walls and under stairs cupboards. Treatment of the common furniture beetle is carried out using Permetherin based micro-emulsions and Boron for severe infestations.
The Death Watch Beetle (Xestobium Rufovillosum)
This beetle can cause extreme damage, they are normally found between March and June when heard tapping. Often found in large sized hard wood timbers such as oak, they sometimes fall from severely damaged wood and can be found on the floor beneath. The presence of dampness is essential for their establishment and rapid development. They are therefore often found in areas prone to dampness such as wall plates, the ends of floor joists and timber lintels. Treatment is carried out using Boron based preservatives and eliminating sources of dampness.
The Powder Post Beetle (Lyctus Brunneus)
These beetles are only found in timbers containing starch such as furniture and strip flooring, not in softwoods. The bore dust is cream-coloured with a talc-like consistency and is often found in small piles. They can be found in heated buildings all year long usually on or around damaged timber. In the latter stages of infestation sapwood disintegrates leaving only the skin of the timber!. Plywood is also often attacked. Treatment is carried out with boron based preservatives and kiln sterilisation to prevent re-occurrence.
