USES: to prevent bed bugs, to eliminate fleas, ant problems within the home. Suggested use: Although this product is non-toxic, special caution should be taken as the fine dust particles can get down the chest, so a mask is worth wearing. Use it on your own beds and the pets beds (Making sure they are out of the room so the dust doesn’t irritate) this kills any flea eggs and prevents bed bugs at the same time. Apply to a cat or dog's coat slowly and gently so dust doesn’t fly around IF there is a flea infestation. Use if you have an ant issue within the home.
