Harris Diatomaceous Earth Crawling Insect Killer is a ready-to-use powder that kills cockroaches, fleas, ants, bed bugs and silverfish. Insects that contact or ingest it die within 48 hours, and because it works physically rather than chemically, they cannot build immunity to it. The puffer-style bottle lets you dust cracks, crevices and baseboards indoors and out. It suits households wanting a non-spray, low-resistance option, but it is slower than contact sprays and must be kept dry to work.

Buyers rate it well for effectiveness against crawling insects and like the easy-to-use puffer bottle. Complaints center on the mess of applying powder and the slower kill compared with sprays.
Harris Diatomaceous Earth Crawling Insect Killer is a ready-to-use powder insecticide made with diatomaceous earth. It kills cockroaches, fleas, ants, bed bugs, silverfish and other crawling insects. It can be used indoors and outdoors.
Insects that come into contact with the powder or ingest it die within 48 hours. Unlike liquid or spray products, diatomaceous earth is not something insects can become immune to.
The 9-ounce bottle is puffer-style and works as the applicator. Apply the powder in cracks and crevices and in other areas where insects are found. Not intended for human consumption. Always follow the label instructions and keep out of reach of children.
