We've got a lovely tower of bee bricks outside our studio which have recently become very much inhabited! Lunchtimes are spent fascinatedly (not quite a word but sums it up!) watching the bees heading in and out of the various cavities, building and provisioning their nests. It really is a beautiful site and something we're sure most children would enjoy watching too. And because they aren't aggressive there's no worrying about being stung. So there's still time to get your bee brick or block out in place and enjoy watching the action, just make sure they are in a warm sunny spot and near plenty of feeding sources for the bees.
