Diatomaceous Earth


Diatomaceous Earth consists of fossilized remains of diatoms that can be used as a natural method to control many common garden pests and even deter rodents from the garden. OMRI listed for organic use.


Diatomaceous Earth contains fossilized remains of diatoms which can be used to control many insect pests. Diatoms are aquatic invertebrates that have cell walls made of silica. When diatoms die, their bodies accumulate into particle aggregates called marine snow. Once these particles reach a certain size, they sink to the bottom of the ocean and accumulate as diatomaceous earth.

This Diatomaceous Earth formulation is food grade and can also be used in animal feed as a pelleting agent or anti-caking agent. The silica composition of DE kills insects by ingestion or contact with the powder, which cuts the exoskeleton and causes dehydration within 48 hours. Because there are no chemicals, insects cannot build a resistance to it. It will effectively control ants, earwigs, cockroaches, silverfish, crickets, fleas, millipedes and centipedes.

Safety Data Sheet

Diatomaceous Earth Uses:

  • Crawling insects: Water plants and sprinkle the plant vegetation with the dust. Once it dries and sticks, it will kill the insect once they ingest it.
  • Slugs and other molluscs: Sprinkle in a circle around the base of the plant to keep them from eating your brassicas and other vegetable plants.
  • Aphids: Dust the plant vegetation or mix it in a sprayer and spray the dissolved formulation on the plants.
  • Ants: Dust the plants if the ants are crawling on the plant and sucking sap from the fruits. For ant beds, sprinkle liberally on the mounds.
  • Flies: To control fruit fly populations, sprinkle on the plants and around the base of the plant to reduce populations.
  • Rodents: Mix lemon or peppermint oil with DE and sprinkle around the perimeter of your garden to deter rat, mole, mice and rabbit pests.
