IMO DE is not very effective... dusting the coop with sevin dust (5-7%) works well, and treating the birds with pour on ivermectin for cattle (spot on, for the chickens) is usually 99% effective. I usually treat 7-10 days later for any eggs that might have survived/hatched. I do the first dose orally (injectable version of ivermectin) for new birds tho, to get any internal parasites too. then spot the second round.Yeah, remember my 3 roos that sere supposed to be pullets? They have mites. Good think I didn't break quarantine just yet. I doused them all with DE and the coop too. I'm making a trip to the feed store for something stronger. I also dusted all my other birds and the run, in case I had some contamination from my clothes or shoes. Anything else I should do?

I have dusted birds directly with sevin dust 5% but that was an extreme case. got a canary with air sac mites that were pretty bad. paper lunch bag, small shake of sevin, insert canary seal and shake... taken on the word of an old man, and you know what? it worked! he lived 2 more years after that..
