To clarify my post #235, I bought Gordon's Permethrin 10 to help turn back an infestation quickly. We inherited a bottle of Elector PSP spinosad from a friend (yes it is expensive, but if I was convinced it was the best/safest option for the chickens, I would buy it). After reading many threads and posts on this site, talking to friends and neighbors with poultry experience and conferring with our vet, we decided to use the spinosad about 30 days after the initial treatment with the permethrin. Our intent was a one/two punch in case there were some resistant mites or lice. Now that we have finished a treatment of each and have no visible bugs or nits during our inspections, our plan is to treat the chickens as needed based on our weekly chicken checks, not religiously every month whether they need it or not (as my post inferred). As for the coop and run, we have several options in our barn including a spray hot steam cleaner that I really like, neem oil (which we have yet to use), the permethrin and spinosad. Since we were actually dealing with an infestation, we went with the same permethrin/spinosad treatment 30 days apart in the coop and run. Our ongoing maintenance will center on using the steam cleaner and alternative safe options as I figure them out from this site and experience, and know that we have an effective treatment in the permethrin and spinosad if and when we need it.
I gotta say, I love seeing all the BYC chatter on concepts like prevention, control, management and all the treatment and maintenance options. It's what makes this site so informative, interesting and addictive. It seems in the absence of a lot of scientific method and qualified vets, much of our chicken knowledge comes from experience, trial and error, advertising, articles in chicken mags and books, friends and neighbors, websites, blogs, hearsay and wives tales. I can understand why there are so many different opinions and hot topics. For us, keeping chickens has been a fluid situation the past two years as we gain experience and knowledge and hone our own method along the way. Thanks to all of you for contributing to our chicken obsession!
