How To Use Diatomaceous Earth To Keep Pests Out Of Your Garden
Diatomaceous earth is a powdery substance with an abrasive texture and high porosity that makes it useful for keeping pests away from your indoor and outdoor plants.
This powder disposes of bugs by cutting them. The microscopic particles in diatomaceous earth have sharp, razorlike edges that cut through the insect’s exoskeleton.
It also dehydrates the insects. When an insect’s moisture-laden fats and oils are exposed to the absorbent powder, it dehydrates them from the inside out.
To use diatomaceous earth as a preventative measure, sprinkle it in locations where you witness the most insect activity to dry up their normally moisture-rich habitat.
To keep flies and gnats away from houseplants, sprinkle some diatomaceous earth at the base. This deters them from laying eggs in the soil and keeps other crawling insects away.
If insects are snacking on your vegetable garden, dust diatomaceous earth around the plant’s base and on the surface of the surrounding soil to deter them.
Diatomaceous earth contains trace minerals like calcium, magnesium, phosphorus, and silicon, which help condition your soil and prepare it for proper plant growth.
It also easily absorbs and retains moisture, which makes it more resistant in drought-affected environments and gives the plants an improved structure.
While diatomaceous earth is considered non-toxic, err on the side of caution and use a food-grade variety. Wear a mask when using it and store it in a dark, dry place.
