That's a good choice you made Pete, if you're allergic to insect stings, you have no business trying to exterminate them yourself. I've yet to have a reaction to them, got stung 7 times on the head once by bald hornets, they'd made a nest above the shop door that I was unaware of, opened the door one morning when I was gonna hitch up the boat for a fishin trip, I made the trip, but the first thing I did when I got home was spray those buggers, kilt em dead, then burned the nest best I could with kerosene in a barrel. Did the same thing to a yellow jacket nest one night several months later, it was on the other end of the shop over the big door, neighbors on the alley pointed the 3lb coffee can sized nest out to me, that was a bit scary since it was near the peak of the roof under the eave, but the hornet/wasp spray did it's job in two nights, there were a few still alive the morning after the first spraying, but the second spraying made em all dead.
The bad thing about insect stings is you may not be allergic to them your whole life, then you will be all of a sudden after the next sting, that happened to Jack, my huntin/fishin partner, he almost died from anaphylactic shock, fortunately he and his wife figured it out soon enough. Ever since then he keeps a bee kit handy. I keep an Epi-Pen and Benadryl capsules in the car just in case one of us ever needs it, all I had to do was ask my doctor and he prescribed the Epi-Pen for me.
Bob makes a good point, I have a couple paper bags full of it left over from my buckskinnin days, it works great for wadding in muzzleloading shotguns too.
