Woodworm is the term used to describe the larvae of wood-boring beetles. The most common wood destroying beetle found in Irish buildings today is the Common Furniture Beetle (Anobium Punctatum)

Female beetles lay their eggs in cracks and crevices in timber and, when the eggs hatch, the young grubs remain in the wood for between two and four years. They slowly eat and burrow beneath the surface of the wood until they develop into beetles.

They are mosty found in timbers with elevated moisture (attics, suspended timber floors) and if left untreated, can lead to weakening of the timbers and can cause serious damage to building structures.

Often Woodworm is identified by the exit holes in wood as seen here. These holes are as a result of the beetles leaving the wood as adults meaning the damage is already done.

Conditions for Woodworm

The Common Furniture Beetle can lay up to 50 eggs in the cracks and crevices of hardwoods and softwoods. For the environmental conditions of a property to be suitable for the eggs to hatch, the relative humidity would need to be above 60%. Properties with persisting damp conditions like condensation due to inadequate ventilation.

Anobium punctatum are historically known for causing damage to furniture as antique furniture was usually made from beech, a much cheaper, less durable timber. This is how the common furniture beetle got its name. Furniture is often found to have decay underneath because the bottom would have been in contact with damp floors making it vulnerable to infestation.

How to Identify Woodworm

There are many species of Woodworm, all preferring different wood types. Some like hardwoods such as sweet chestnut, mahogany, oak and ash. Others prefer softwoods like cedar, spruce and pine.

Look for signs of exit holes in timber. These holes would vary in shape and size, depending the species of Woodworm present. This is where they exit the timber to repeat the process over. They also leave galleries which almost look like little tunnels in the wood. Bore dust (Frass) is also another clear indicator of woodworm infestation. This is also as a result of the beetle emerging from the wood.

Woodworm Survey and Remedial Treatment

Before making a decision on treatments, Acorn Property Preservation will consider the condition of the infested timber, the species of woodworm and the risks and hazards associated with the remedial action. Acorn Property Preservation will provide a detailed survey report to specify woodworm remedial treatments and works to be carried out by our experienced team of technicians and trades people.
