How to use Permethrin for lice?

[P-Funk]

I got a 1 Pound can of 'Gordon's Dairy and Livestock Dust' at Big R. It say Permethrin and (bare with me) 2-didimethylcyclepropanecarboxylate - 0.25% and 99.75% inert ingredients. 95% of the instructions are warnings, mainly for humans. The only instructions for poultry say 'apply at a rate of 1 pound per 100 birds'. I had planned on sprinkling the run and raking it in the dirt.
For the coop I have a pressure washer, a bottle of bleach, a can of blu kote, a bottle of poultry protector, alfalfa, bags of new shavings, and a beer (for me). I was planning on going to town until I read the directions on the 'Dust' can. P

Use just like poultry dust. Take each bird, one at a time. It's great benefit to have a helper. Hold the bird by both legs, head down. Dust the vent area well. Dust the underside and massage the feathers to get the dust down to the skin. Dust under each wing. Then, right the bird. Dust the neck area. That is usually sufficient.

Go get another bird and repeat.

It is likely that another course of dusting will be required 8-10 days later to catch any eggs that may have hatched. I wouldn't dust the run.
