Reg­u­lar ap­pli­ca­tions of DE can help re­duce the num­bers of in­sect pests in the en­vi­ron­ment. It can be ap­plied to the skin, or sprin­kled on sur­faces around your coop.

When the body of an in­sect comes up against its sharp, spiky sur­face, the DE causes des­ic­ca­tion of the outer layer, which in turn causes de­hy­dra­tion and then death of the in­sect. It’s a slow process though, tak­ing up to a week to cause a no­tice­able ef­fect.

Re­searchers have shown it works well ex­ter­nally, but the news isn’t so great for its use in re­duc­ing in­ter­nal worm bur­dens. Tri­als of cat­tle, sheep and goats fed food grade DE showed no re­duc­tion in worm bur­dens, nor preven­tion.

“DE does not have an ef­fect on par­a­site loads as mea­sured by fae­cal egg counts… DE does not re­duce anaemia, as mea­sured by packed cell vol­ume and other blood pa­ram­e­ters.”
