Not Vespula vulgaris though?
... but I do spend much of the year moonlighting as an earwig farmer apparently...
Well I hope you buy them in from a specialist foreign earwig breeder who lives in a completely different climate and that you don't rely on local mating of your own earwigs. All the local ones are mongrels, you know. Furthermore, it requires many thousands of earwigs for a selective earwig rearing programme to work.As I only have two hives, I'm just an earwig hobbyist......
Some further observations.
I have also been collecting wasp queens in the house as they awake and bounce around the windows. Two in a jar with a loose lid survived 4 & 6 weeks at the back of the fridge. Added a third yesterday, was interesting to note that when they warm and wake they do not fight as you might expect honeybee queens to do.
So in principle it should be straightforward to collect live wasps over time into a vented container in the fridge, then post them out in say groups of 4 per introduction cage, with a little fondant to sustain them whilst active. This would make the 'wasps by post' scheme proposed earlier much more economically viable.
I have had just about enough of Queen wasps this winter. Not many under hive roofs but many, many more then usual indoors. It is so bad that none of us will wear anything from the wardrobe without turning it inside out for a good shaking first. I reckon we must have had one or two on the loose every single week since around the start of December. One appeared in the back porch yesterday under a clean towel that I had wrapped a batch of soap (made partly with my beeswax, of course) in to cool down. I'm starting to wonder if they're watching me. Today is a good day. I haven't found one. Yet. I also check under the pillow at bedtime as I once found one there too.
I kill them. I'm pretty sure I have plenty more hiding here somewhere.

Next time pack them carefully and send to Cardigan or Durham where they will be better appreciated!
