Treating woodworm

Our specialists begin with the application of our specially designed insecticide formula. The method of application varies depending on the type of beetle larvae present and the extent of infestation. This is why we always recommend hiring a professionally qualified specialist.

Our woodworm treatment guide will outline the steps needed to make sure that your home is safe and free from wood boring beetles.

Step 1: Determine if the infestation is active

A woodworm survey is the most accurate way to determine if you have an active infestation or not. If a qualified surveyor determines that treatment is required then your surveyor will inform you of the required course of treatment to solve the problem.

Step 2: Applying woodworm spray

Our specially designed insecticide formula can be applied to large areas. This is usually applied via spray but localised infestations can be treated by brush. This water based solution is a highly effective woodworm killer. It has been proven to eliminate beetles and larvae, and is a certified woodworm treatment for floorboards, furniture, oak beams, lofts and attics.

Step 3: Lasting woodworm protection

The active ingredients in our woodworm solutions 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.

Step 4: Reoccupying rooms after woodworm treatment

Treated rooms can be reoccupied just one hour after treatment has dried, minimising disruption to you.

Injection woodworm treatments

Depending on the beetle, an injection of insecticide into the timber may be required. For example, Deathwatch beetles are particularly destructive species that can burrow deep into timber including hardwood. In instances like this, the woodworm treatment can be injected deep into the exit holes left by adult beetles. This will target the remaining larvae and kill them before they can cause further structural damage.

House Longhorn Beetles are another woodworm species that require careful consideration. In minor cases, the same methods we would use to treat Deathwatch beetles can be enough. In most cases, all timber in property will need to be treated and surveyed for structural integrity issues.

Woodworm survey

In order to establish the best course of woodworm treatment for your property, our professionally trained surveyors will conduct a detailed woodworm survey. Our woodworm surveys are conducted by surveyors accredited by leading trade bodies. This gives you peace of mind that they will provide the highest level of industry knowledge and insight in order to correctly identify and treat the insect.

Peter Cox survey process

    1. No Obligation Telephone Call or Book Online - One of our customer service team will speak to you via telephone, listening to your concerns regarding a potential infestation and offering advice on the best course of action. Alternatively, you can book a survey online straight away using our online booking form.

    2. Schedule Survey - Following speaking to one of our woodworm specialists, if it sounds likely you may have a woodworm infestation, we will arrange a date and time for one of our surveyors to visit your property.

    3. Property Survey - One of our woodworm surveyors will visit your property to examine the timber for suspect signs of woodworm, locate the infestation and determine whether or not it is an active woodworm infestation.

    4. Written Report - Following the survey, the surveyor will provide you with a written report detailing any issues found and if required, a proposal outlining the necessary steps to remove the infestation or repair any structural damage.

What are the different types of wood boring beetles?

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

  • Common furniture beetle
  • Deathwatch beetle
  • Wood boring weevil
  • House longhorn beetle

You can read more about these species of beetle on our guide to woodworm page.


What woodworm spray products do we use?

The technicians at Peter Cox use a unique treatment known as ‘Insectasure’.

This 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 application.

How much does woodworm treatment cost?

To arrive at an accurate estimate, we would first have to conduct the survey at the property.

Naturally, the findings of the report will affect the final price and this will be determined by factors such as:

  • The extent of the infestation.
  • Scale of treatment required - ranging from full house fumigation to localised spraying or brushing.
  • Do structural timbers need to be repaired or replaced.

Can I treat woodworm myself?

There are many DIY solutions and “woodworm killers” available in hardware shops that can be very effective, particularly on furniture. If you are certain the infestation is localised to a sideboard, chair or dresser, then a professional solutions is likely not required and a DIY beetle treatment or "woodworm killer" will suffice.

If you suspect woodworm has got into the timber frames of your property then we would always recommend getting a professional to help and following their advice on treating woodworm. These pests can spend between six to ten years hidden in your timbers. This makes it incredibly hard to determine how severe the infestation is until it is too late. By that point, the wooden beam, joist, or surface may have been structurally compromised.

Also, while our professional surveyors use chemicals that are safe long-term, their application does require strict observation of COSHH regulations. This is why our team use protective clothing and equipment when treating structural timbers and floorboards.

How can I prevent woodworm?

  • Keep timber dry - Woodworm larvae thrive in moist timber. Timber with a high moisture content is at greater risk to a woodworm infestation. This is because damp wood is easier to chew than dry wood. Adult beetles will tend to lay their eggs in damp wood where its larvae will have a greater chance of survival
  • Check second hand furniture - If purchasing second hand or antique furniture, make sure to check the furniture for signs of  a woodworm infestation before bringing it into your home. The common furniture beetle is often mistakenly brought into homes via infested furniture.
  • Remove infected timber - If there is a piece of timber in your home infested with woodworm, it's important to remove it from your home as soon as possible. This will prevent the adult beetles from spreading to other wood in your home.
  • Apply varnish - Applying varnish to timber will make it more difficult for water to penetrate it and therefore less likely to attract woodworm.

Do I need woodworm treatment?

Any of the woodworm signs listed on our dedicated page could be an indication that you might require treatment, however, the real way to see if woodworm is active in the wood is to look out for any frass, which is the name given to beetle droppings.

The frass look like a fine sawdust and will usually be around the holes in the infested timber. It is not the most glamorous job in the world but it will help you find out if the woodworm infestation is active and whether you require a treatment plan or not.
