MSDS Sheet Product Data Sheet

Your home may be at risk! It is a common misconception that woodworm only effects older properties, however, this is simply not the case and extreme damage can also be caused in newly constructed buildings. In fact, any wooden structure, furniture or worktop can be infected with woodworm eggs or larvae without it being overly apparent.  These larvae then consume the wood before leaving when they have reached maturity.

There are a few tell tale signs that you might have woodworm and if you spot them then you should use SkilledBuild Woodworm Killer straight away to prevent any further damage. These indicators are small round holes in your woodwork (think of the holes in a dart board), fine, powdery dust around these holes, crumbly edges to boards and joists and perhaps even adult beetles emerging from the holes or being found around the house.

SkilledBuild Woodworm Killer is a premium, concentrated, microemulsion insecticide based on the low toxicity contact insecticide Permethrin; which has been specially designed to prevent re-infestation as well as eradicate Common Furniture Beetle (Anobium punctatum) and other wood destroying insects. Permethrin's well known effectiveness as a remedial insecticide has been enhanced further by the use of a micro emulsion systems which means that optimum pesticide dosing occurs.

Our Woodworm Killer is fast acting, effective, economical and has the major advantage that it has virtually no smell making it easy to use without filling your house with toxic fumes!
