Q Is the product safe for people using it, and for the homeowner?
A The only thing left in H2 LOSP termite resistant timber in the long term is a synthetic pyrethroid, considered some of the least harmful to all mammals of any insecticide. Permethrin has low human toxicity and is essentially trapped in the fibres of the timber as it is essentially non volatile and non water soluble. In H3 LOSP timber there is the added organotin fungicide present, which is also has very low solubility in water. Both products remaining in the timber have had their use in these situations approved.
