Barrettine Premier Woodworm Killer contains permethrin, and is a fast and effective way of killing woodworm and their larvae. Ideal for ceiling and floor joists, floorboards, wooden beams, furniture, doors and more.

Insect attack can be recognised by small round holes on the surface of the timber and the gritty bore-dust that is left behind. These holes are most likely to be found near joints or on the undersides or backs of furniture. Whilst holes indicate that beetles have emerged, it is likely that larvae remain in the wood.

Ensure the wood to be treated is clean, dry and free from dust.

  • Any previous finishes such as paint, stain and varnish must be completely removed
  • Special precautions should be taken when removing pre-1960's paint surfaces over wood as they may contain harmful lead

Always do a test area before starting any project and follow the manufacturer's instructions on the tin at all times. This product is not suitable for use on areas used for the preparation and consumption of food. Do not apply in conditions of high humidity or if rain is likely before the product has fully dried.

  1. Apply by brush, covering all faces, ends and joints paying particular attention to the end grain, corners and crevices
  2. Allow 2-3 hours between coats
  3. For prevention of attack by wood destroying insects, apply 2 coats; on structural timbers apply 3
  4. For eradication of wood destroying insects, apply 2 coats; on large timbers apply 3

Areas treated with Barrettine Premier Woodworm Killer can be over-coated with a wood paint, varnish, stain, wood oil or wax when fully dry.

Very pleased with the product by Diana Mirfin

Very clear instructions, easy to use I poured the liquid in a spray bottle as it was easier for me to use. Delivery very quick indeed, I would not hesitate to purchase again from Wood Finishes Direct in the future. Thank you.

Safe and easy to apply and fitted the purpose perfectly by Mr I Elgie

Required an effective control for pest attack on an expensive large traditional African drum. The product was easy to use, and after a few days no residual odours and I believe it has no hazardous residuals when the drum is used in a domestic situation with young children around.

Goes on easy, penetrates well Good price by Craig

Great stuff. Soaks into wood deeper than water based versions. A little bit of smell but quickly clears. Easier to spray on than to brush, used old kitchen cleaner spray bottle that doesn't mist. Can't tell if woodworm dead yet but surrounding flies die pretty quickly. Got next day delivery and was still cheaper than anywhere else.

Seems a good Product but only time will tell by Peter Page

Barrettine woodworm killer was easy to use and the smell was not overpowering but as far as effectiveness goes, only time will tell. I have used Everbuild Woodworm killer in the past (supplied by a different company) and that did not stop woodworm attacking the oak I used it on, which is why I thought I would try this product. Delivery and packaging by Wood Finishes Direct was faultless as was their website which was not only easy to use but very informative as well. I will be shopping there again very soon.

Great product, easy to apply by Richard Jones

I used this to treat the floor in two rooms and was surprised by how easily it was to apply. Although it smells quite strong it was not nearly as bad as I thought it would be. I would definitely buy it again (in fact this is already a repeat purchase).

Great product, delivered quickly, Thank you! by Richard Jones

As the liquid is quite 'thin' it is easily applied and quickly absorbed into porous woodworm affected wood. Although it does smell it was not as strong as I was expecting which was good news. It is obviously too early to tell whether it has successfully eradicated the woodworm but my first impressions of this product are excellent.

Good effective treatment by Graham Alexander

A good product gets the job done, a little smelly and does take a long time to dry out (two days on my occasion) however I have been able to finish the wood off back to its original glory without significant effects on finishing such as wax oil and French polishing....

Very easy to use and apply - bit smelly, so need to ventilate by TrevorM

Well - get back to me in a few years and I'll let you know if the woodworm is still there! Used to treat an old piano we just acquired (126 years) as it had some signs of live woodworm. 'orrible vapour though, which I believe is standard for these sorts of products - need to ventilate the room well.
