Woodworm / Wood-Boring Beatles

Woodworm Infestation or Wood Boring Beetle, as it is commonly referred to, is found in many residential and commercial buildings. Damage to timbers can occur, as wood boring beetles are able to use wood as a food source.
One of the most unfortunate parts of a woodworm infestation is that the signs of the problem are only visible at the end of the woodworm’s lifecycle. This is when the woodworm breaks free from within the timber to continue its breeding. The signs to look out for are what we call exit holes. These holes in the wood or timber can be between 2 and 5 mm in diameter meaning they can often only be spotted up close, unless there is a large infestation and many exit holes together.
As well as the exit holes, there is a second way to identify a woodworm infestation. This is through the presence of frass. Frass is a dust created by woodworm. The frass or woodworm dust is light in colour and looks almost like very fine wood shavings. This frass is essentially woodworm waste and it can be this waste that can help us identify what type of woodworm is present. For example… the frass produced by the wood-boring weevil is ‘sticky’ to the touch as a result of there been moisture present.

Where woodworm treatment is required, our product range includes water based, low odour preservatives which in many instances, require properties to be vacated for only short periods of time. Full details are provided for each specific project, following a site inspection and risk assessment by our Surveyor. The most common method for woodworm treatment is involves exposing the timbers by lifting floorboards in a parallel manner to gain access to the sub floor void.

The joists, wall plates, bearers, sub floor timbers and the underside of the floorboards are then treated using insecticidal timber preservative.

The Insecticide is specially formulated for deep penetration into the timbers, in order to ensure eradication of existing woodworm infestations and future protection of the timbers.

Treatments are completed by our own skilled operatives and most woodworm treatments are completed within one day.

Our woodworm products have been granted a one hour re-entry status, therefore the treated property can be re-occupied once the timbers are dry (minimum of one hour afterwards).

Following inspection by our Surveyor, we will provide a report of our findings and a quotation for treatments if found necessary. Our timber treatments are guaranteed for up to 20 years, depending on the type of infestation and the proposed treatments.

Full details of the guarantees available will be provided with the report following the inspection and assessment.

Common Furniture Beetle (Anobium Punctatum)
What does it look like?
● Small, dark, reddish.
● 3mm – 5mm in length.fg
● Regular lines running down its wings.
● This common furniture beetle is by far the most common cause of damage encountered. Its specialty is sapwood of softwood and European hardwoods.
Signs of Infestation
● Round holes approximately 1.5 ¬ 2mm in diameter.
● Small piles of frass seen within tunnels or on surfaces.
● Frass will have a gritty texture. 

Deathwatch Beetle (Xestobium rufovillosum)
What does it look like?
● Chocolate brown in colour.
● 8mm in length.
● Patches of yellowish hairs.
● The Deathwatch beetle usually attacks oak, however it will attack Softwood if well¬rotted and in contact with infested hardwood.
Signs of Infestation?
● Round holes about 3mm diameter.
● Extensive tunnelling.
● Lots of frass usually present; frass is 'bun' shaped, readily visible to the naked eye.

Wood¬boring Weevils (Euophryum confine and Pentarthrum huttoni)
What does it look like?
● Small, brown and black.
● Up to 5mm in length.
● Distinctive long snout.
● Antennae one third distance along snout.
● Wood¬boring Weevils attack both softwoods and hardwoods which have previously been subject to decay.
● Destruction is most commonly seen in damp skirting boards and embedded joist ends.
Signs of Infestation
● Tunnelling in sapwood tends to run along the grain.
● Tunnels are narrow, around 1mm diameter.
● Frass is likely to be 'sticky' due to the dampness.

To treat the wood and timbers, our technicians will enter the infected area to initially prepare for the treatment. Preparation involves:
• Moving furniture
• Gaining full access to the room
• Take up floor boards is necessary
• Clean timbers so they are free of dust
Once our technicians are happy, they will protect themselves with the most appropriate protective equipment and begin spraying the water¬-based treatment directly onto the wood. The solution will be absorbed into the wood over a period of about an hour, killing and getting rid of all living woodworm and eggs near the surface. Woodworm that are already deep inside the wood will be killed as they eat through the treated timber upon emergence.This could be some considerable time after the treatment has been applied dependent on the life cycle of the woodworm.
