Attaching the vacuum to the intake is such a clever solution!
In some areas, you can contact a company who will come out for free and collect yellow jackets (and similar creatures) for making anti-venom. My parents have needed them several times, when they were inside greenhouses, the front door of the house, and other places where they don't share airspace politely. Usually we had to have enough critters to make it worth their time driving all the way out to my parents' house, so two or three trouble spots. The worker uses a protective suit and a strong vacuum situation to suck out the wasps, and physically removes the nest.
We have found this company to be helpful and friendly:

I wonder if this kind of business exists in other areas?
