Northern fowl mites on rooster

[Dani2236]

2 ounces or 60 ml per 3 gallons of water (Permectrin II) is what a link I just read is for poultry mites. That is equal to 20 ml per gallon. Spray each bird with 15 ml (1/2 ounce.) Label is below. In cold weather using permethrin dust is preferred, and a sock filled with powder is a good method.
