Nothing is better !!

I'm fighting the battle against the mite in poultry for decades, but I had long-term success with any of the various remedies - and I have over the years all by what is already pretty much freely available or only available on prescription.
While you have the impression that the critters laugh about the various sprays, drops ect. more dead than they are received (which is not necessarily true of the bronchi own ..) it, it's my first time succeeded with Agrinova mites free, the dung actually completely get rid of things over a longer period.
I have every animal at the critical points dusted deliberately so (ie around the cloaca around and under the wings) - Result: Even after the first application crawls since absolutely nothing more! I then repeated the first week, after some time then only once a month - since neither black nor red mite!

I am absolutely thrilled, especially since the stuff is also more toxic. Well, breathe I would not necessarily recommend, is apparently in no time in the airways firmly - and leads at least for me to appropriate coughing ... but you must not do so.
In the big chickens I do that now already in passing (a spray at the bottom and is well's), could not be easier. The nests are also sprayed - that's it.

I can only recommend all mites afflicted, I do not need anything else!
