What Is Diatomaceous Earth?
Diatomaceous earth (DE) is a fine white powder made from the fossilized remains of tiny aquatic organisms called diatoms. At a microscopic level, the particles are sharp-edged. When crawling insects walk through DE, it damages their exoskeletons and causes them to dehydrate and die — typically within 24–48 hours. No chemicals, no toxins, no resistance buildup.
What Pests Does Diatomaceous Earth Kill?
- Cockroaches
- Ants
- Silverfish
- Bedbugs
- Fleas
- Mites and dust mites
- Most other crawling insects
DE is not effective against flying insects or pests that don't walk through it directly.
How to Apply Diatomaceous Earth
Sulguy Diatomaceous Earth Powder is food-grade and safe for use around children and pets when applied correctly. Apply a thin, even layer — a light dusting is more effective than a thick pile, which insects will avoid.
Best application spots:
- Along baseboards and skirting boards
- Behind and under kitchen appliances
- Inside cabinet edges and hinges
- Around pipe entry points and gaps in walls
- Under furniture and in corners
- Around the perimeter of the home outdoors
Important: Reapply After Moisture
DE loses effectiveness when wet. Reapply after mopping, rain, or high humidity. In bathrooms and under sinks, reapply more frequently.
Combine With Other Non-Toxic Methods for Best Results
DE works best as part of a layered approach:
- Sulguy Cockroach Gel Bait — targets the nest directly for cockroach infestations
- Sulguy Peppermint Spray — deters new insects from entering treated areas
- Sulguy Glue Traps — monitors activity and catches stragglers
