Woodworm treatment in Berkshire, Hampshire, Surrey & Oxfordshire
There are many types of insects that use wood as a habitat. Some insects are restricted to the forest, others can live in timber that has been felled and incorporated into the home. The most commonly known wood boring insect is known as Woodworm, and prepurchase reports frequently call for Woodworm surveys to be conducted and woodworm treatment carried out if required.
What types of woodboring beetle attack are found in Homes?
The main form of insect attack in wood in the UK is beetle. We have included a description of four beetles that are of interest to property owners as they are most commonly referred to in building survey reports (Woodworm, Deathwatch beetle, House Longhorn and Woodboring Weevil). The correct identification the type of insects that has attacked the timber and whether it is active is a prerequisite of proper treatment. In many cases, there may be no justification for chemical woodworm treatment,
Evidence of woodworm (common furniture beetle) and deathwatch beetle is often found in older properties during building surveys.
Deathwatch beetle is common in buildings were oak has been used in construction and has subsequently been affected by damp and rot.
House longhorn tends to be restricted to certain geographical areas in the UK.
Wood boring weevil is commonly found in rotting timber and can be misdiagnosed as woodworm. The presence of wood boring weevil indicates the presence of damp conditions and therefore risk of timber decay.
What is Woodworm and how is it treated?
Woodworm refers to the larvea of a wood boring beetle (anobium punctatum aka common furniture beetle), the woodworm larvea lives in the wood for several years. Woodworm consumes the wood, before they pupate and the adult woodworm beetle emerges from the wood leaving the tell tale signs of woodworm frass trials and woodworm emmergence holes. Woodworm attacks softwoods and the sapwood for european hardwood, however woodworm require wood to be above a certain moisture content to survive.
Woodworm Treatment and how much does Woodworm Treatment Cost?
If active woodworm is detected, then woodworm treatment is required. The type and extent of the woodworm treatment required will be determined following a specialist timber survey. The cost of woodworm treatment for a standard domestic property will be in the region of £800-£1200 although woodworm treatment of the entire property is not always required.
The most common form of woodworm treatment is the coarse spray application of a preservative, although micro fogging woodworm treatment is available for inaccessible areas. Woodworm treatments should only be carried out by trained woodworm treatment operative in accordance with the Property Care Association code of practice for Woodworm treatment.
Biocraft carries out woodworm treatment and specialist timber surveys and woodworm surveys throughout Berkshire, Hampshire, Surrey, and Oxfordshire.

Common furniture beetle (aka Woodworm, anobium punctatum) is the most common wood boring beetle in the UK. Many older properties will show some evidence (~1-2mm exit holes) of woodworm activity in floor boards, joists, rafters etc. although whether this is a current active attack should be determined before any chemical treatment is performed. Below is an example of ongoing beetle activity.
The common furniture beetle lifecycle
Adult beetles mate and lay eggs on suitable timber. The eggs turn into larvae (worm, grub) which burrow into the wood and spend 3-5 years eating/burrowing their way through the wood that they inhabit. They derive nutrition and water from the wood they inhabit. When ready they pupate, and then when the beetle emerges from the pupa (chrysalis) they chew their way to the surface and emerge from the wood leaving the signature emergence/exit holes.
The emergence period is approximately between March/April and September, at which time insects can sometimes be seen on the surface of the wood or flying through the air in a roof space. When the insects emerge they leave a trail or pile of finely chewed wood (frass) which looks like fine saw dust. The presence of this frass by emergence holes is an indicator of current ongoing activity.
This insect attacks hard woods, usually oak. It is usually associated with some rot activity and is commonly found in Churches. This is where it derived its name as the tapping noise made as a mating call could be heard in the timber of the church.
Death beetles resemble woodworm although it is larger, with ~3mm holes, the grubs are larger and there is a lot of bun shaped frass in the tunnels. Deathwatch beetle is not usually found in Scotland or Northern Ireland.
This insect can cause severe structural damage in a relatively short period of time. It is a large insect that produces large oval holes (6-10mm in diameter) and tunnels, which coalesce, resulting in severe internal damage.
This insect tends to be restricted to the South East, especially in Camberly in Surrey. Presence of House Longhorn Beetle in a property should be reported to the BRE and the attack should be treated if it is active.
Wood boring weevil
This insect occurs in timber that has rotted, common in kitchen floors where damp has caused the boards and joists to rot. The tunnels tend to be along the grain, occasionally breaking the surface. Weevil activity is frequently misdiagnosed as woodworm.
Treatment involves the removal of the source of moisture and timber repairs. If there is no rot there will be no weevil.
All 15 species of bats in the UK and their roosts are protected under the Wildlife and Country side Act 1981. Under section 9, it is illegal for any person (without a licence) to intentionally disturb, injure or kill a wild bat: to possess or exchange a bat, or to intentionally damage or obstruct access to any place that a bat uses for shelter or protection.
Bats do not make nests or cause structural damage, so the most obvious signs of bat activity is presence of their droppings.
Remedial companies are duty bound to inform the property owner to liase with the governments statutory nature conservation organisation (SNCO), English Nature in England, Nature Conservancy Council for Scotland and Country Side Council for Wales, in relation to any works in bat inhabited areas.
A programme of treatment will be devised in coordination with the SCNO to ensure that the bat habitat is not disturbed.
