Wasps Nest

Discovered the startings of a wasps nest this morning on the balcony, I've been out there every day this week and not noticed, but the wasp has obviously been trying to start the nest in a few places along the roof. It's only small at the moment but when the wasp isn't around I can just about see the cells inside. I'm tempted to leave it to see how it progresses.....however I'm not a big fan of wasps and neither are the kids!
