I've been using the Quiko Ardap Fogger - made vermin nebulizer with us very good experience. Today, we use it on our daughter in the henhouse, because they, too, had a strong mite infestation. They hide in crevices in the straw, etc. So first all chickens in the open-air site, then all the straw out and burned and cleaned the floor. Pressing the Dose and deflates completely. After 2 hours, we opened the door, but still kept the chickens. After another 4 hours later fresh straw released in the laying nests and the barn. I've done this with us in December and since then is just as calm and I'm sure this barn is now bug-free. This remedy is highly recommended!
