Depending on the situation, there are several ways to apply diatomaceous earth: around the house, in the garden, on your pets, and many other places. It comes in a loose powder, so it can be messy to use without applicators or measuring utensils.
DE is most effective when dry because the diatoms will vigorously absorb unwanted spills and smells, or dehydrate insects. However, there are also circumstances, where a wet application is needed. Either way, DE will be effective once it dries. When applying diatomaceous earth (or any fine dust) in large amounts, you should wear gloves, a face mask, and protective goggles. This is to prevent irritation to the skin, eyes, and lungs and these items can be found on our accessories page.
Diatomaceous earth is unique in its versatility. It can be used and applied in a way that works best for you. For instance, dry treatments can be applied with a flour sifter when working around the house. You can sprinkle it in cabinets, around baseboards, in window sills, beneath refrigerators or stoves, on a pet bed, in the garbage can, and many other areas. A flour sifter would also be useful for a light treatment on the carpet, when dealing with insects, or you could use it to sprinkle your garage and around the perimeter of your home.
It's easy to apply diatomaceous earth in a wet mixture. If you are using DE to treat your garden, you can mix DE and water into a spray receptacle. After you've mixed the two at a ratio of four tablespoons of DE per gallon of water, apply a thick coat on the tops and undersides of all your plants. When applying it to grass, wet down the grass with the hose. Then apply a heavy layer of dry DE through a dust sprayer onto the grass. Once the water dries, the DE will stick to the grass. Reapply once a month, especially after it rains.
There are even ways to apply a wet mixture of DE as a cleaner around the house. You can also spray DE wet for a natural pesticides, around the home, on the farm, or in the garden.
You can use a turkey baster to apply DE along cracks and corners in your home or other hard to reach places. A salt or pepper shaker will work well for small spaces as well. For another precise method, you can use a paint brush to work the diatomaceous into a specific area. Also, nylons and mesh bags work well to use DE as a deodorizer in your home.
