I've never had great results with anything for killing them, but everything seems to work just fine when sprayed on the nest. they never come back to the nest. For killing them while they are flying, or even when the land, all the stuff that I use will knock them down, but then they get up and fly away. I have to stomp on them to kill them after spraying them.
My exterminator told me about Dawn Dish soap mixed 50% with water. You just spray everything with this and they never come back. They hate the soap residue.
As a contractor, I run into nests all the time. I stop whatever I'm doing and start spraying. I always have two cans with me. Right now, I have four because I'm working on a house that seems to have more then normal. I also spray myself with DEET once I know I'm dealing with wasp nests. Up on a ladder, it's hard to run away when they get mad!!!
For best results, and the least amount of risk to myself, I go after them the most aggressively early in the morning when it's the coolest outside. This is especially true in an attic. They are sluggish and easily killed with out risk of attack when it's cooler out.
Dawn dish soap works on Bumblebees too. A little bit in a sprayer with water is all you need. I read in some tech magazine that the Dawn coats their bodies and makes it impossible for them to breathe and they suffocate. All good with me. I still like brake cleaner for it's kill speed.
