How to treat woodworm

The first step is a professional survey to locate the areas of infestation, accurately identify the species involved and determine whether the infestation is active or not.

Once woodworm has been identified in the property, the technicians at Peter Cox use a unique woodworm treatment known as ‘Insectasure’. This specially designed insecticide formula can be applied to large areas via spray or used to treat localised infestations by brush. It has been proven to treat timbers, eliminate beetles and larvae, and is a certified woodworm treatment for floorboards, furniture, oak beams, lofts and attics.

Once the wood and timbers have been treated with InsectaSure woodworm treatment, the active ingredients work in the following ways:

  • If a female lays eggs on the surface of the timber, when the larvae hatch they will ingest the treatment and die
  • Beetles already in the wood will ingest the treatment as they emerge out of the wood at the end of their lifecycle, killing them before they have the chance to mate and lay eggs
  • Treated rooms can be reoccupied just one hour after treatment has dried, minimising disruption to you

Woodworm treatment in the roof or attic

For woodworm infestations in lofts and attics it may be necessary for us to temporarily remove insulation to gain access to the appropriate areas. We will sweep down timbers to remove dust and debris from purlins and rafters, and protect any water tanks and exposed electronics.

Once the area has been suitably prepared to allow maximum effectiveness for our treatment solution, then the surfaces will be thoroughly sprayed on all sides and any removed insulation will be re-laid.

Woodworm treatment to floorboards

For serious woodworm infestations on the floor we will lift up any carpet to expose the area and lift up the floorboards every meter across the room.

Our special woodworm insecticide solution will then be sprayed into the void underneath the boards to ensure the underside of the floor, and the sides of floor joists are treated thoroughly before we re-lay the floorboards and spray the top surface.

Woodworm in staircases

Our woodworm treatment specialists have a special process to deal with infestations in staircases.

We will first pull up any carpet covering the stairs and drill either side of the carpet line so we have two holes in the riser. This allows us to insert a nozzle designed to diffuse the insecticide woodworm killer solution in all directions to ensure the void space is thoroughly treated before we treat the top surface and the relay any carpet that was lifted.


Although more commonly used in commercial premises there are certain circumstances where it would be more appropriate to utilise a fumigating gas treatment to eradicate woodworm and other insect infestations.

In cases such as this we will  cordon off the affected areas and inform the client of the suitable time before they can rehabit rooms.

Will woodworm treatment prevent future infestations

Insectasure woodworm treatment solution has been specially designed to remain within the layers of timber, in any cracks and exit holes after treatment. This means that it will not only treat existing infestations, but will also protect your property against fuure attacks from woodworm.

For further safeguarding we offer woodworm insurance that provides complete protection for any potential infestations in the future.

Is Insectasure woodworm killer safe?

The insecticide solution we use during our woodworm treatments is a non-flammable, low odour water based micro emulsion insecticide has been approved by the Health and Safety Executive (HSE) and rooms are perfectly safe to re-occupy just one hour after treatment.

Types of woodworm species that require treatment

It is important to identify the species of woodworm present in your home because not all actually require treatment. Indeed only a select few pose any danger to the timbers in your home, these are:

  • Common furniture
  • Death watch
  • Wood boring Weevil
  • House Longhorn

You can read more about these woodworm species on our dedicated woodworm beetle page

DIY tips for treating woodworm

There are a number of “woodworm killers” available in DIY and hardware shops and they can be very effective,  particularly on furniture that shows signs of woodworm. If you are certain the infestation is localised to a sideboard, chair or dresser,  then professional woodworm treatment is not required and a DIY woodworm treatment will suffice.

If you suspect woodworm has got into the timber frames of your property then we would always recommend getting professional treatment.
