Solitary bee transparent nest box
Has anyone used the solitary bee monitoring box, as featured on Springwatch this year? They are apparently easy to clean of mites and great for kids.
I have five floor bug hotels and drilled wood all over the place, but I read they can harbour a lot of parasites etc. I can't imagine the made holes, bamboo stems etc could be worse than the bees etc would naturally find, but lots of people seem to be worried about it. Bodies like the RSPB and the Wildlife Trust are still promoting them, so, who knows.
