Diatomaceous Earth, DE for short, is made up of diatoms, old sea bed creatures collected from dry lakes around the Great Basin area. The fossilized creatures have very spiny bodies which when applied to plants where soft bodied insects lurk, tend to poke holes in those critters such as aphids or larval stages of bugs. This picture is a not so good DE application on hot pepper plants that the ants had farmed some aphids on. Yes, ants raise aphids so they can get the nectar the aphids suck out. Not sure exactly how it works, one of those symbiotic things. DE can be applied with a duster(mine died) or a flour sifter or even a sieve. Just don't breath the dust as those same silica particles can lodge in lung tissue forever.
