Super delivered quickly. Have dusted immediately the entire henhouse so. After 2-3 days were clearly less mite in the stable. Nevertheless still do every 2nd to 3rd day, perches, etc. pollinate with the powder to permanently get rid of the mites. But it is now bearable when you enter the barn. It is no longer immediately "under siege" by the mites. Can not recommend this so, I would buy again. And what is also important, it is a natural product and therefore not toxic to the chickens. They can even stay in the house when spraying, when they want it. With the powder bottle I have no problems, works flawlessly.
