Woodworm

What is Wordworm?
Woodworm is a general description covering several species of wood-boring insects. The most usual being the Common Furniture Beetle (Anobium punctatum). The life cycle of this and other wood boring beetles including Death Watch Beetle (Xestobium rufovillosom), House Long Horn Beetle (Hylotrupes bajulus) and Bark Boring Beetle (Ernobius mollis) all follow a similar sequence over varying life spans with differing effects and damage to the timbers.

The life cycle starts with the adult beetle laying eggs in the crevices of the timber. These hatch into larvae that tunnel into the timber then, following pupation, the adult beetles emerge through small flight holes to start again and spread the infestation. The first visual indication of an active infestation will normally be the appearance of these flight holes accompanied by the bore dust.

Why is Woodworm a problem?
Woodworm can cause structural failure to built-in and decorative timber, including furniture within the building, such as roof timbers, staircases, floor boards and joists

How would DrySide rectify the problem?
– Survey
In occupied properties, our inspection is normally restricted to the readily accessible timbers only, as the fitted floor coverings and furniture limit the extent of our inspection. Ideally, we would like all such obstructions to be removed prior to our arrival. We strive to give as best as possible an assessment and identify the specific species of infestation by wood boring beetle, determine whether it is old and no longer active, and advise if treatment is required. With timber rot/decay we identify the cause, the proposed extent and methods of treatment, and other associated building work. If a complete condition and assessment of all timbers within a building is required we recommend that a fully intrusive inspection be considered. This will require the removal of areas of wall plaster, to expose embedded timbers such as lintel above windows, wall plates etc. The opening up of floors adjacent to the external perimeter walls of the property is essential. This type of inspection is available at a cost.

– DrySide Surveys
DrySide carries out inspections according to your instructions on properties in relation to basement waterproofing and rising damp, as well as timber defects, such as infestations by wood-boring beetle (woodworm) and decay such as Wet Rot and Dry Rot. The purpose of our inspection is to provide a report with justification, specification and quotation for our proposed works and treatments.

The inspection is carried out by specialist qualified staff holding Certified Remedial Treatment Surveyor (CSRT), Certified Surveyor for Structural Waterproofing (CSSW), as recognised by the British Wood Preserving and Damp Proofing Association. Additionally they have passed the examinations of the School of Waterproofing, as well as many manufacturer’s exams and training courses.

Our senior surveyor alone has over 26 years surveying experience. DrySide offers an honest, balanced and informed opinion, which is not restricted to any single manufacturer or pay-related bonus/commission scheme, thereby enabling us to provide our clients with a reliable report, giving justification for our works, identifying the extent of such work and the proposed specifications, with a realistic quotation in relation to your instructions.

– Treatment
The purpose of these treatments is to control infestations by wood-boring beetle (Anobium punctatum), which may be affecting the accessible structural timbers within the property. This is done by applying an insecticidal fluid to the accessible surfaces of the timbers. The chemicals we use are aqueous-based permetherin (unless otherwise stated in our report) and all have approval and are HSE registered by the manufacturers. Full Safety Data Sheets relating to these chemicals are available on request. To control active infestations of wood boring beetles, we apply the aforementioned chemicals to the manufacturers’ specifications, generally this works comprises of:-

1. Roof Timbers
Sweep down timbers with brooms.

Double saturate all accessible roof timbers within the roof void with a pressured spray applied Permetherin-based insecticidal fluid. We will require all stored effects, insulation, and boarding to be removed from the roof void prior to our technician’s arrival, unless otherwise stated in our report/quotation.

2. Staircases
Treat all accessible unpainted staircase timbers with a double saturation of pressure spray applied Permetherin-based insecticidal fluid. We will require all carpeting and stored effects in the under stairs area to be removed prior to our technician’s arrival.

3. Floor Timbers
Lift strategic floorboards, as necessary. This is approximately every 1.2m or every 4 to 7 floorboards.

Double saturate all accessible floorboards and sub floor timbers with a pressured spray applied Permetherin-based insecticidal fluid. Relay floorboards then double saturate by pressure spray the topsides of the floorboards and immediately adjacent unpainted joinery items with a Permetherin based insecticidal fluid. We will require all floor coverings, carpets, furniture and effects to be removed prior to our technician’s arrival.

With tongue and groove floorboards, and exposed and polished or varnished floorboards, some damage will occur when we are lifting the floorboards as part of our treatment. Naturally, we will do our best to keep damage to a minimum but you must accept this risk, as we cannot accept claims for this damage.

Where no specialist timber treatment works are recommended by ourselves and/or timbers appear to be free of active infestations by wood-boring beetle, we are not saying that future specialist remedial works or treatments will never be necessary. We therefore recommend that periodical checks/inspections be made every three to five years.

Children, mammals, and pets should not be allowed within the areas of treatments during, and for a period of at least 1 hour after completion of our treatments.

We require clients to provide a suitable safe electrical and clean running water supply free of charge.
