Hello, list friends -- I have been told of man who catches wasps with a bee-vac, kills them with dry-ice in an ice-chest, packages them in plastic bags labelled with the correct taxonomic name, and sells them to the pharmaceutical industry. Does anyone know anything about this? Might be a good way to justify getting or building a bee-vac. Lord knows, this part of the world (Louisiana) has a lot of wasps. Walter Weller
