The product available in the UK, under the Provado trade name has practically no strong smell, unlike virtually all previous insecticides I have used. At least to my nose. It is available in powder, ready-made liquid and dilutable liquid form. The latter has sunflower oil in it, and gives an oily emulsion, maybe so it wets and clings to mealy bugs and the like.
