I use a duster to apply sevin dust. It's the best way when using the powder type insecticides. I think doing it that way would be better than a liquid spray in the coop or barn. The duster has a can you fill with the dust, and you pump the handle, (like a bicycle pump), to spray the insecticide out of the nozzle on the end. I occasionally dust my workshop and garage with it, then use the gas powered blower to blow the dead roaches and loose dust out a couple days later.
Here's one type of hand duster...
