You just did a home lab experiment and saw the difference between DE and permethrin. While both are dusty powders, they are very different. DE is the powdered remains of the skeletons of ancient ocean creatures. If you were to examine it under a magnifying lens, you would see lots of very sharp particles. When lice encounter these razor sharp particles, they get cut and damaged. This is also why DE is dangerous for all air breathing creatures as it can injure lungs and the respiratory tract. However, the damage it may do to the lice or mites is inefficient as far as doing a thorough job. Many of the vermin will escape and keep on living on your chickens or coop.
Permethrin is an insecticide. It's toxic to insects and damages their brain cells and nervous systems while still being safe to use around chickens due to the toxin in it only targeting the insects, not chickens or people. As an efficient insecticide, it will eradicate the lice or mite problem immediately.
