Death at Dusk

Some pictures may be worth a thousand words, but probably not this one!

This is a small gap between a weatherboard and the top of the frame of my front door. A couple of days ago as I was closing the door, two european wasps (Vespula germanica) arrived and crawled into this gap. Not nice! Although normally I don't like to kill anything, sharing my house with a nest of european wasps is a bit more than I can handle. Tonight at dusk a can of wasp killer was sprayed into the hole, and the hole blocked up. Now my fear is that in the morning they will find an alternative way out, and be inside my house...
