How Woodworm Killer Works
Permagard Woodworm Killer is based on microemulsion technology. This means it is formulated with nano-particles - the tiny size allows the active ingredients to travel deep into the wood. The highly effective pyrethroid insecticide prevents wood boring insect attack and reinfestation as well as killing any active wood boring insects.
How to use Woodworm Killer
Permagard Woodworm Killer is easy to use. Start by making sure that the timber is clean and free from wood dust, contaminates and surface coatings such as oils, waxes and paints. Then, simply spray, brush or dip apply the woodworm killer on to the target timber for complete woodworm treatment. 
Wood treated with this woodworm Killer can be overpainted, varnished or stained when dry.

I used this woodworm killer on my floorboards and joists. wont know if it works or not yet but fingers crossed. it does have a smell as you would expect but not too bad.i used a spray hand pumped to apply every now and then the filter blocked with a white residue but was easily cleared . the product arrived the next day even though it said 1-3 days for delivery . would buy again.

Service and delivery is always fast and efficient. But you can’t expect a review of the product until the next life cycle. Should the woodworm tunnel out next year and die without spawning back into the treated wood then I could give 5 stars. But I trust the company to provide 5 star products, and that’s all I can say
