How Diatomaceous Earth Works

Diatomaceous earth is made from fossilized remains of aquatic animals. These remains create a naturally occurring silica compound that will kill off the pests. Although it appears as a flour-like dust, the silica grinds away at an insect’s exoskeleton. This slowly dehydrates the pest until it’s dead.
It is not toxic to humans or pets. However, there are some precautions you should take, including:
- Wearing gloves, as it can dry out skin.
- Wearing a mask, as inhaling any substance can be harmful.
- Using only food-grade diatomaceous earth.
There are three grades of diatomaceous earth available. The only one you should use around your home is food grade diatomaceous earth.
This is especially important if you plan on using this product on yourself or your pets and livestock. Food-grade diatomaceous earth contains 84% silica. Higher amounts of silica can be toxic to humans.

Dry Application

The best way to apply diatomaceous earth is applying the powder directly. To do this, you’ll need some rubber gloves, a mask, and something to apply the product. You can use any of the following items to apply this product:
- Puffers
- Turkey basters
- Paint brushes
- Flour sifters
This product is quite powdery. Keep a dust buster on hand for easy clean-up. Since this product is safe to use around kids and pets, you only need to wipe it down with an everyday cleaner.
Use puffers and turkey basters to apply to large plants, on bed bug traps, and on your pet. This keeps the diatomaceous earth targeted and easy to clean up.
Use large or small brushes to apply a thin layer to your entryways and window sills. This way, the diatomaceous earth is the first thing a pest touches when it enters your home.
For larger areas, such as gardens, use a flour sifter to evenly spread your diatomaceous earth.
Wet Application
Diatomaceous earth needs to be dry in order to work effectively against pests. You can apply it in a wet formula, but it will need to dry before it’s effective against pests. Applying this product wet initially is great if you’re worried about the product flying off in the wind.
Experienced gardeners will apply this wet formula to coat plant leaves. This allows the plant to absorb the water and later protect against any pest who dare nibble on the leaves. To make your own wet applicator, mix:
- ½ cup of diatomaceous earth
- 2 cups of water
Pour the slurry mixture into a spray bottle and spray onto garden plants. Remember the product will take a few days to be in effect.
We found this method wasn’t as effective as applying it dry. We wouldn’t recommend this method, but it would be helpful when trying to get your diatomaceous earth to stick to plant leaves.
