Ronseal Woodworm Killer

Ronseal Woodworm Killer contains permethrin, an effective woodworm killer, which will prevent the infestation and spread of woodworm, thus avoiding the associated damage.

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 woodworm holes are most likely to be found near joints or on the undersides or backs of furniture. Whilst holes indicate that wood beetles have emerged, it is likely that woodworm larvae remain in the wood.

Please Note: This product is not suitable for use on areas used for the preparation and consumption of food.
