In treating for mites, do you think the powder or spray works better? I used poultry dust 7 days ago, it has permethrin in it. TSC also has permethrine spray that can be used on poultry. If I go with the spray how much do you put on them? Putting the powder on them didn't go to bad I just wondered if the spray was easier and if it worked any better? Thanks, Deb
