I'm working on a stall in the Royal Mile, Edinburgh, right now. We often have cans of Irn-Bru which the wasps like. One wasp would come and drink from the top of the can and then tell all the other wasps. Now we have a special can of Irn-Bru that lives on top of one of the glass cabinets with a straw so that we can suck up some more Irn-Bru when they've finished what's on the top of the can. They get a bit agitated when there's no Bru on the top. It works a treat. They just come in, fly straight to the can, drink, then buzz off without coming anywhere near us or our customers. Some people use jam jars with jam and water. We use Irn-Bru. Once we tried it with a can of coke but they wouldn't touch it. It seems our wasps are true Scottish wasps. Only the Bru will do. As soon as we arrive they start hanging around the stall so the first thing we do is get them their Bru.
What do you think of this?
