I have a question while we are on the topic:
Permethrin is incredibly harmful to cats...which i have. Id prefer not to get the stuff. Anyone have treatment recommendations that dont involve it? I know prevention is key and ive taken the steps but just in case...
I tried Permethrin and it didn't work here. Tried Seven Dust, diatomaceous earth, wood ashes, other poultry sprays, etc. I was cleaning out and replacing shavings every week. Nothing controlled the serious infestation of mites we had. Someone even tried to tell me to coat my henhouse with used motor oil!!! Oh, my gosh, NO! That stuff is carcinogenic...full of heavy metals, and a possible neurotoxin!
I found, through much research and trial and error, a mixture that will really knock out the mites, yet is safe to humans, pets, chickens, etc. It can be toxic to honeybees, though, but I only use my mixture inside the henhouse where no honeybees would go.
There is a substance called Spinosad that kills the mites. It is an ingredient in the tablets given to pets to control fleas and ticks. It is also in Monterey Garden Spray. I get the undiluted form of the Monterey and mix it with SaferGro PestOut (oils of cottonwood, garlic, clove) and water in a one-gallon garden sprayer and coat the inside of my henhouse. Depending upon how heavy the infestation is, you can use just one ounce each of the spinosad and pestout per gallon, or up to about 4 oz each if it's really out of control. There are more concentrated brands of spinosad online, too. The mites are controlled and the henhouse smells like Christmas. You can also mist the chickens with this mixture, just watch out for their eyes because clove oil can STING!
