Honey bees live in bee hives and bumble bees live in holes in the ground...what kind of bee are you expecting to come and stay in an empty tube of bamboo ?
My garden is full of bees the Lavender bed, Ceanothus and Hebes seem specially attractive to them and are often covered on a sunny day. I love to hear their soft humming.
I don't use any pesticides of any kind because of all the wildlife including frogs and hedgehogs .
What a great idea for a present, thanks. I think it is the solitary bees that use them. I have a bee friendly garden too, but not noticed many honey bees this year.
