You betcha! Mine are Northern Fowl Mites. I hope I'm winning, but have little faith. Winters are a loss here; can only "effectively" treat in winter because of the cold, dampness, and wind. I found I had to use TWO drops of ivermectin pour-on each for my tiny OEGB's for roundworming, so I'm guessing that the one drop I was using for mites (these birds weight one pound) might not have been quite strong enough. Diatomaceous Earth (D.E.) did exactly NOTHING. Permethrin powders and sprays helped, but didn't do it. Last week I bathed each bird, let her dry, and used two drops of ivermectin pour-on, while at the same time I poured permethrin spray all over the walls of the (small) coop, sprayed the roost bar, and removed the sand from inside the house and it's annex. I washed the sand in water, and after draining it I added permethrin concentrate. Do I think they're gone? Can't see any, but I doubt it. I have a dirt run, and surely there are some that got missed here and there. I'll continue the spraying of the house and the drops on the banties, and hope to get rid of them before winter. I feel so badly for them, being bitten. A word on Poultry Protector; it really does knock them dead when I saturate them, but too expensive to dip the birds in it, unfortuately! I do use it in some of the cold (non-freezing) months to at least kill a bunch of them around their vents, as this is where most of them are on mine. Can't get the girls very wet, though, in the cool months.
Good luck! Keep us posted.
Do you have any other predator-proof structure you could use during the warm months, to try to get them away from the hiding mites while you treat, and let the hiding mites die off before the winter months?
