Is Tempo SC Ultra suitable for wasps found in the void of the wall?
Is there a three-month residual effect?
Tempo SC Ultra can be applied in a wall void, but dust products are much better suited for flying insects. Our most popular dust for bees/wasp is Tempo Dust. You will need a hand duster to apply it with. It usually works within 24 to 48 hours. You want to go up to the opening where they are flying in and out of at dusk or at night when they are not active and puff twice directly into the hole. Then pull the duster out and puff directly at the hole to cover the opening from about 5 inches away. This is the most efficient and fastest way to eliminate a bee/yellow jacket/wasp nest.
