I did some research and apparently it can be used in Dairies, barns, feedlots, stables, poultry houses, swine and livestock houses, animal hospitals, pens and kennels, outside meat processing premises. Since it does list poultry houses, I'm going to use it according to the directions, in the coops. I'll shut the birds out while it dries. I'm not going to use it on the birds. I'll keep using the permethrin dust on them. It comes to a third of an oz of permethrin to 1 gal water. I read it will also control fleas in yards as well as many other lawn pests and also for the control of mosquitoes. Every once in awhile a truck comes down our road spraying at night. I wonder if it is using a permethrin spray for the control of mosquitoes. We are on a dead end road, the truck goes to the end and turns around and comes back spraying the whole time. I get it on one of my game cameras.
