Clean all the bedding out, bag it or burn it. Clean all the nesting boxes out bag it or burn it.I have the kind in the coop that attack at night. Turned on big light and flipped hay and saw them run. None on girls during day. Checked 4 yesterday. Looking for how to start by treating coop
Get a 2 gallon garden sprayer. Mix liquid permethrin and a spinosad. Spray everything! Don't forget the ceilings. All cracks and crevices. That's where tehy live
Use vaseline under the roosts so it will trap the mites when they come to feed at night. I mix liquid permethrin with the vaseline. Very effective.
