Recently we have been having some issues with birds getting into our coop. Lots of them. We fixed the problem but now have a nice case of mites in this coop. This is where my younger birds are. I dusted all of the chickens really well on Tuesday, but I am still seeing live mites. I'm going back out to dust (DE) Again tomorrow. When I dusted last time, we really dusted good, did perches bedding, ground, etc. I was kind of surprised to still see mites walking thru the powder still on the skin of the chickens. Granted, it is fewer but I expected all to be dead and just needing to retreat every week to get rid of the newly hatched mites. I'm using DE. Should I try something different? How long will mites remain alive after coming in contact with DE. Will they die from DE "dust" or do they have to come in contact with large amounts of the powder? I'm going to try the "chicken in a bag" technique this time. Anything I can give them to make them less appealing to mites?
