Yellow jackets/wasps

[birchl]

We got a nest of something nasty in the lava rock crack. We tried spraying wasp poison down the crack but all that did was upset them. We tried burying the crack with mud but they are still buzzing about so there must be more than one way in. They are very small, and very aggressive. To matters worse I suffer from localized allergic reaction, which basically means if I get stung I swell up like a balloon. Any suggestions?
