The nest is not visible. We have used aerosol sprays in the opening in the shingle, but they have not been effective. This problem has occurred in other areas of our home in past seasons. We have used an exterminator in the past, but at this point, it's too expensive. I believe we need a powder that can be applied to the opening that the wasps will carry into the nest. I reside in NY.
Tempo 1% dust would be a great insecticide dust to use around and in the openings where the yellow jackets are entering and exiting the shingles. Tempo Dust formulation contains one of the most effective compounds available for quick knockdown and long-term residual control of stinging insects. We do recommend that the dust be applied with a hand duster to be sure the dust is getting into the crevice.
