Hi all, in the UK with have a product called Diatom. It is used to prevent red mite and can also be used as a wormer. The instructions are very poor on how to use. It states 5% in food and from what most people say you do this 3-4 days a month. Has anyone in the US got any better instructions on the correct dosage. It can also be used for dogs,cats etc for worms and flees
