Insect Dust

Comprised
of diatomaceous earth, which is made of fossilized water plants
so tiny and sharp that they lacerate the insect body and cause
death by dehydration within 48 hours. Because it works mechanically
upon the insects, they won't develop immunity. It may be safely
applied indoors or outdoors, around home foundations, in corners
and crevices inside. So safe you can actually rub it into your
dog or cat's fur. If you apply with a duster, wear protective
gear to avoid inhaling dust. Controls ants, fleas, ticks, cockroaches,
earwigs, slugs, beetles, and silverfish. 6 lb bag treats 2,500
sq ft.
