Most mites were after the first application nahzu all dead. I still have a few mites in the house (probably are those on my chicken it were). When I see that, then I spray on these bodies to the powder. Before I used the resources I needed to just open the door and already itched after a few seconds my skin because some mites equal "it continued" to me. Now I can easily go back to the barn into or stay longer next to the stable without that I take from a mite note.
I have done everything with my first high-pressure cleaner "clean". Then I read the barn to dry (the powder works allegedly only when everything is dry - which makes sense). Only then I applied the powder.
A few more notes:
1. The included spray bottle is nice but is only suitable for partial use. To order a full stall (and my only 2 m² is only 1.4m high) to edit it is simply too impractical. But if one only to a certain point or a small area would apply the powder to be suitable (if the rotation has to get out).
2. best connect Therefore a gun to the compressor and this spread / apply the powder in the henhouse.
3. What I also recommend (like others already): necessarily a dust protective mask when applying the powder.
