The wasps I'm referring to are red wasps of some sort, the body is dark red and they have yellow/orange legs with clear wings. Their nests are paper and usually not much bigger than a baseball, tho I have seen them as big as a dinner plate.
There are usually a small group of wasps that build a nest 5-6. I spray on the nest and get 3-4 of em instantly, then move back a little till they land somewhere and pick em off one at a time. The sprayer shoots at least 10ft so its easier to stay out of the "attack zone". They never fly more than 3ft after being hit. When we replace facia on our rentals, the soap offers genocidal results. Hornets are rare here because of the freezing winters. Bumble bees are plentiful however, and don't appreicate being bushogged... but that's another story.
