Can’t remember where I learned this but I heard, or read, that moth balls get rid of them. I have used them on paper nests that were in various spots (outside) and a ground nest last summer. Just stood back and chucked the moth balls until I got a few in or near the nests. Every time I have used the moth balls, the yellow jackets, (and once bumblebees) split in two or less days. I still have the open box out in my shed and they keep out of there too. These have always been exterior applications. Good luck.

I had this exact situation once. Call Marvin at Jerry the Bee Guy. Poison free. He's a total character too.

Thanks, all, for the suggestions. After carefully considering your endorsements for firebombing, selling my house, poisoned cat food and skunks, I decided to try setting up a shop vac by the entrance. Been going for two hours now and it's gone from about 20 per minute coming and going to just a couple per minute. Also, I'm pleased that they haven't freaked out and started swarming. More of a "Hey, where's Bob? Hmmm, what's this? Ackk....(slurp)" I have some soapy water in the vac to drown them but phase two will be making sure they don't get out until they starve I have to give honorable mention to the classiest suggestion, though:

Remember, you will have to empty the shop vac someday. I rebaited my trap with the available at the store specific bait--no catfud, and hung it near a spot where the beasties were going under the house siding. The trap already has quite a few in it.

You may already know this, but some places (like this one) advertise free wasp removal. One other point: We had some kind of wasps in our attic and we called an exterminator to remove it (me being a coward and all). I don't know what kind of wasps they were, but they were mostly black and big and scary and with a loud eeeeeeeeeeeeeeeee sound. The bug removal guy immediately identified it as a beneficial wasp that was harmless and would not remain; and practically begged us to leave the nest alone. So we did, and sure enough, they left!
