It is currently winter in the midwest and I'd like to know the best time to apply this to the eaves of the house to help prevent wasps from nesting there come spring/summer.
If applied into voids for wasp control, the best time to apply Tempo 1% Dust is when these pests start to become active. It will work best for wasps when it's fresh. If you believe the area you will treat may have moisture build up, it would be best to use Delta Dust. Delta Dust is water-resistant and can easily be applied with any of our hand dusters.
