What spray that is in a concentrated form, not aerosol, would be best?
There are not a lot of options that we typically recommend as a contact kill in a concentrated form that you would put in a pump sprayer. Most nest eliminating products would be in the form of an aerosol to kill that nest instantly. Or if the nest is in an eave of a home using a dust like Tempo 1% Dust is always a great way to get the wasps to carry the product back to the nest as well. For a contact kill only in a concentrated form, you would go with something like ExciteR Pyrethrin Concentrate. You could then follow up the nest areas around the home with a residual like Tempo SC Ultra or Cyonara 9.7 to help keep them from being a continuous problem throughout the season.
