I am battling mites that I found in the coop last Fri. So far I have sprayed down the coop twice with a Permethrin solution (followed the directions on the 8% goat stuff) and fumigated (twice) with a pyrethroid recommended by the livestock people. Tonight I still found a couple of live mites in there and in my opinion, two mites is two too many. Of course I am dusting my chickens like crazy also and will put Ivermectin on them tomorrow. Unfortunately my coop is a board and batten design which allows a multitude of hiding places for the mites. I am willing to bathe my chickens once I am sure that the coop is mite free so they don't get re-infected, but I am worried I'll never be able to get rid of all of them. Do they overwinter in the coop? Is there anything I can do short of getting rid of the coop? or buying another one and letting this one lay empty for 6 months? HELPPPP?
