Overview
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.

Definitely yes
Work great, almost no odour and dries very quick. I used it with a sprayer which made application really easy and swift even though I misjudged the amount needed, think I'll need 3 cans since I decided to treat the whole vanity as prevention and not just the affected areas. Dires with no residue so no need to fuss about what finish to apply at the end.

Excellent product and the cheapest in the area so great value Member of staff was extremely helpful and friendly with good advice so will be using the store again
Seems to have stopped the woodworm in its tracks. Very smelly though so you need to ventilate the area.

I haven't had wood worm yet
Easy to apply with a garden pump sprayer for great coverage. It doesn't take forever to dry either, so you can get on with a finishing product. I use it as a preventative measure, so it's hard to rate it really as I'll never know if I would've got woodworm or not, but for the price it's a a no-brainer for piece of mind.
