what is the best way to apply it? i read that you spray it on, but how do you do that? with a hose? and do you lay all of the frames out on the ground and then spray them? anyone have any suggestions?
mixed in small amounts and use a spray bottle mixed in large amounts use a garden sprayer It doesn't take all that much to be effective, just a good misting will do. After mixing the shelf life is short (if not mistaken 3 days), the powder has a very long shelf life.
Mix 1 teaspoon with water in a quart spray bottle. Spray about 25 frames. Then mix another quart. Or mix 4 teaspoons per gallon of water and use a larger sprayer.
Make sure to store the unused powder in a place close to room temp. Extreme heat does something (kills?) that makes it ineffective.
