Todd from Philadelphia Pa writes
I have carpenter bees that have drilled holes and nest in holes at the bottom of garage roof trim. If I spray it upward in the holes, will the small amount of dust that sticks to the inside hole be enough to treat?
Yes, the Evergreen Pyrethrum Dust 1% will stay put inside of the carpenter bee bore holes. Dust have an ability to cling to surfaces very well in areas that are protected from wind, rain, or other elements. No need to worry about the dust coming out of the bee bore holes.
