My name is Dr Margriet Dogterom and am the founder and owner of Beediverse. I write this blog for all who love bees and who want to learn more about these wonderful creatures.
Great pictures. I am not too sure who the culprit is here. Several mason beekeepers have sent me pictures with cotton in and around nesting tunnels. We are still searching for the culprit!
Yes, the large yellow grubs look like beneficial wasps. Clean out the rest of the channels, and close up the nesting tray. Set out with cleaned trays ready for next spring. Margriet
We are excited that Beediverse will be at the next Seattle Flower and Garden show on Feb 20-24 2013. Come and visit our booth and bring your questions. We will have lots of knowledgeable people at the booth to answer your questions.
We are at Booth 2319. We are sharing a large booth with West coast Seeds. A combination of mason bee products, mason bee cocoons and seeds will be available for your garden.
I have been busy harvesting all my cocoons, cleaning cocoons and nests, doing mason bee workshops and getting ready for the busy December and spring seasons.
November is the beginning of the real winter season, and unless you have already dealt with your mason bees, this is a good time to open your mason bee nesting tunnels, harvest mason bee cocoons and clean the nest.
Of course there are a lot of details that are missing from this list, but the above list is an overview.
