  • Sprinkle bands of DE around the plants you are trying to protect. It’s important that the ring of DE does not have any gaps for pests to sneak through.
  • If pests are eating the leaves of your plants, you can dust the leaves with DE, which should discourage further damage. However, you should avoid applying DE near the plants’ flowers, where pollinators might inadvertently come into contact with it.
  • When using DE, it’s recommended to wear eye protection and a dust mask, as the small particles can be irritating.
  • DE works best in dry conditions. It clumps together when wet, so reapply after it rains.

Although they can exist alone, theyll most often be found together in larger numbers. Examples of bed bug hideouts are under the box spring, in cracks of the bed frame, the stitching in suitcases, and even inside electrical sockets. Apply DE to passages wherever bed bugs travel.

How To Spread Diatomaceous Earth In Your Yard

Made from the fossilized remains of algaelike creatures, diatomaceous earth is a low-toxicity pesticide that controls various species of insects in lawns and gardens, including fleas, spiders, beetles and earwigs. The fossilized remains are ground into a fine powder that contains sharp microscopic edges. As the insects crawl through the powder, the powder absorbs the oils, while the sharp edges tear through their bodies, leading to dehydration and death. For easier application, apply diatomaceous earth with a hand duster.


Remove decorations and debris from the yard. Keep children and pets out of the area for about 24 hours.


Put on protective eyewear, a dust mask and rubber gloves. Fill a manual hand duster with food-grade natural diatomaceous earth.


Stand at one end of the area and turn the hand crank while walking slowly toward the opposite end of the lawn. Keep the nozzle of the hand duster a few inches above the ground. Continue in this manner until you have applied a thin layer of diatomaceous earth over the area.



  • Follow the directions printed on the label of the diatomaceous earth.
  • Apply diatomaceous earth on a calm, warm day when there is no rain in the forecast.


  • Only use food-grade diatomaceous earth or a product made for insect control — not the diatomaceous earth used in pool filtration.

It derives from the remnants of very small, aquatic organisms that are referred to as diatoms. The skeletons of diatoms are made up of a natural substance known as silica. Silicon, which is an element of silica, usually combines with water and oxygen. The end result of this combination is silicon dioxide.

    Diatomaceous Earth is comprised of a particle size that ranges from less than 3 µm to more than 1mm. You will find that most are between 10 to 200 µm.

    How To Create A Diatomaceous Earth Spray

    For a broad and even application of diatomaceous earth, consider making a wet DE spray. Mixing DE with water makes it easier to treat a larger surface area. For instance, to coat an entire shrub, large tree trunk, or pathways and structures. Again, the DE wont be effective until the water evaporates and the DE dries out. Then, the surface will be left with a fine coating of DE powder.

    • Combine 4 to 6 tablespoons of DE per gallon of water.
    • Mix in a spray bottle or garden pump sprayer. Shake vigorously to thoroughly combine.
    • Spray on leaves or the target surface until it is wetted but not heavily dripping off. Focus on the most pest-prone areas, including the underside of leaves.
    • The DE powder may try to separate from the water, so shake your sprayer occasionally during application.
    • Allow the solution to dry and begin to work.

    When it comes to a widespread infestation of aphids, mealybugs, spider mites or other soft-bodied insects on a plant, we prefer to use a DIY soap insect spray over DE.

    What Should I Do If I Spread Diatomaceous Earth On My Lawn

    Put on your breathing mask, your eye goggles and your gloves. Pump up the dust spreader as per the manufacturers instructions and pull the trigger. Keep children and animals off of the lawn for 24 hours. After one full day, sprinkle the yard to dampen the white powder. It is now safe for children and pets to return to the lawn.

    Using Diatomaceous Earth To Control Insects In The Home

    With any pest management situation, its important to know the behaviour and habitat of the insect youre trying to control. Before applying DE, gather a little background information.

    For the best results:

  • Identify the pest and their habitat. For silverfish, ants, roaches, pill bugs, carpet beetles, roaches, fleas, bed bugs, spiders and flies, look in the discreet places where these bugs can hide, such as areas the vacuum or brooms cant reach. Be sure to check behind furniture, fridges, crevices where floors meet walls, at the back of cupboards, and along windowsills.
  • Using a teaspoon, set out the DE in lines that insects will be likely to cross. The more DE they come into contact with, the faster theyll die. Leave these lines in place. Do not sweep, vacuum or get wet. Apply DE strategically behind or beneath furniture and appliances, with an eye toward places the vacuum does not reach.
  • Insects like ants may change routes if they sense a dangerous substance. Monitor the insects behavior and follow up your initial application if you discover theyre not crossing the existing paths of DE.
  • Dont apply generally or sprinkle lightly. Too thin of an application will result in not enough contact with the insect. Ensure you are making thick lines crossing their routes of passage.
