Agrodust contains only silicon dioxide a desiccant dust very similar to diatomaceous earth. The crystalline dust damages the waxy cuticle of the insect leading to dehydration and death providing insect killing power without any active ingredients. This product is particularly useful in enclosed areas where the use of an insecticide spray is not possible or desirable. Agrodust can be used for the control of ants cockroaches mites ticks beetles centipedes bed bugs fleas earwigs and silverfish. Not suitable for outdoor use or open areas where air movement may spread the dust.
