Hi, We have a bumblebee nest in the wall cavity of our home. It is very active with several bees coming and going each minute, and I can hear the buzzing from outside. We are enthusiastic bee lovers and want to do all we can to safeguard them but I am now finding baby bees in my young son’s en suite bathroom which is directly above the nest entrance. I think they are crawling through tiny gaps at the side of the bathroom pipework. We are concerned that he or our other children might end up badly stung but I have no desire to harm the colony. Any advice?
