Signs of woodworm usually consist of tiny holes in wooden items or wooden structures, with live infestations showing powder (feces) around the holes. The size of the holes varies, but is typically 1mm to 1.5mm in diameter for the most common household species. Adult beetles which emerged from the wood may also be found in the summer months. It is the round exit holes that normally identify the timber that has been subjected to a beetle infestation. Once the adult male beetles have emerged from the chamber their sole purpose is to mate with as many female partners in their short lifespan to produce future generations. These pests are seasonal like most other pests, and the woodworm season usually runs from May to October. The most common wood-boring beetle found in British buildings is the Common Furniture Beetle.
The wood-boring beetle named the Deathwatch Beetle is an indigenous British insect. Their larva prefers to munch on sapwood and heartwood of hardwoods, usually oak, which have partly decayed or damp. Wood-boring beetles can fly. Their flight is limited to some extent, but still enough to fly through open windows as any other insect would do. The biggest risk of acquiring these pests is when purchasing old or second hand furniture. Ensure to inspect items carefully!
The female beetle begins the cycle by laying her eggs directly into the timber through cracks, crevices and existing flight holes. She does this, rather than surface laying to protect them. After a few weeks the eggs hatch downwards into the timber and produce larvae – this is the worm stage of the infestation. The woodworm now begins causing structural damage. The worm, or larval stage, carries on for anywhere between 2- 5 years. In that time, the larvae eats its way up and down the timbers and causes the structural damage. It is at this stage in the life cycle that the frass, or dust, that is associated with woodworm is produced. Towards the end of its lifecycle, it forms a pupae chamber where it enlarges the tunneling towards the surface of the timber and pupates from the larval stage into an adult beetle. The adult beetle then eats its way through the last thin veneer of timber producing the round exit holes that you normally see. From here on in the beetle causes very little further damage to the timber. The adult females live for 10-14 days whereas their male counterparts only live between 3-4 days.
Diet: Wood and Fungi
Size: Holes 1mm to 1.5mm
Habitat: wooden items (normally part of a dwelling or the furniture in it)
Scientific name: Anobium punctatum
Structural integrity is essential for both residential and commercial properties which is why a woodworm treatment survey would need to be carried out to establish the extent of the damage. On completion of the survey a treatment can then be tailor made to meet the requirements of your property
