DIY treatment

If you have active woodworm, you can treat the infected wood with special woodworm insecticides that are readily available from hardware stores.

Small infestations can be treated with spray canisters fitted with nozzle, so you squirt the insecticide directly into the holes to penetrate the wood. You can also paint insecticide onto the surfaces with a brush, or, for larger areas, spray it on with a pressure spray-gun.

Make sure you read the instructions carefully and take all the necessary precautions. Because woodworm killer is designed to inflict a swift and merciless death on a living organism, you can be sure that it is not too good for you either.

Call in the experts

For serious and extensive infestations by woodworm, you will have to call in specialist pest control contractors. In addition, really badly infected timbers will have to be replaced.

If you are buying a house, and the survey shows that woodworm have damaged the structural timbers, a mortgage lender will insist that they are treated by a specialist pest control contractor, who, after treatment, can issue a guarantee against further damage for a number of years.

 Upholstered furniture infected by woodworm may have to be fumigated, rather than be treated by liquids – again, a job for the specialist.

I have just had a brand new bungalow built with oak beams. I noticed a white powder dust falling from the beams and then pin pick holes. I told the builder who sprayed some areas (I wasn't there) and was told woodworm doesn't usually go to oak because the wood it to hard
What is your advise on this please
