Natural, mechanical pest control you can trust

Harris 8 oz Diatomaceous Earth Crawling Insect Killer uses 100% diatomaceous earth to target a wide range of crawling insects without chemical additives. The powder is a dry, fine dust you apply in living spaces, basements, attics, and outdoor spots where pests hide. Because the formula is inert and non-toxic when used as directed, it’s a practical option for eco-conscious households seeking a simple, effective solution.

Key benefits

• Powerful crawling insect control without harsh chemicals.
• 100% diatomaceous earth with no additives.
• Kills insects mechanically on contact, not chemically.
• Long-lasting protection indoors and outdoors when kept dry.
• EPA registered (No. 3-18) and backed by a trusted brand since 1928.

How it works

This product acts mechanically. Insects that encounter the powder are affected by the sharp edges of the tiny particles, which damage the exoskeleton and lead to dehydration on contact. There is no chemical residue involved, making it a straightforward, residue-conscious option for pest management.

What you can use it for

This diatomaceous earth formula targets a broad range of crawling insects, including ants, bed bugs, cockroaches, fleas, earwigs, silverfish, and spiders. It is suitable for both indoor and outdoor use and can be part of a practical, ongoing plan for pest control.

Long-lasting indoor & outdoor protection

Keep the powder in dry conditions to preserve effectiveness. Apply along basements, attics, gardens, garages, and entry points to create a barrier against future intrusions. Reapply after heavy moisture or rainfall to refresh coverage.

Ease of use and trusted brand

EPA registered (No. 3-18) and designed with a built-in puffer tip for precise, targeted application in cracks and tight gaps. Harris has provided pest control solutions since 1928, earning trust from professionals and homeowners alike.

Practical tips

• Apply a light, dry layer in cracks, along baseboards, and behind appliances.
