Protecting other bee larvae when cleaning mason bee house

Asked December 1, 2020, 9:59 PM EST

I was trying to clean out my mason bee house--it has wood blocks that clam shell together to form tubes. There are white bee larvae in the tubes along with mason bee cocoons and pollen mites in clusters. How should I handle cleaning the house so that I don't get rid of all the bee larvae but do get rid of the pollen mites? Can I move the white larvae somehow so they are safe and then clean out the wooden block and cocoons?

thanks!

Thank you for your question. It is a little late to clean out mason bee tubes, but this OSU Extension article explains what to do: https://catalog.extension.oregonstate.edu/sites/catalog/files/project/pdf/em9130.pdf This has pictures and lays out the problems and procedures. Hope this is helpful. Good luck!
