 Subject: Mason Bee house with guests?
 We have 2 Cottage style house with a single tube size hole on a door that slides up and door on grooves from the upper right at about a 45 degree angle. 
 
Yesterday I found bark dust piled at the bottom of the ‘V’ where  the door stops.  As I slid the door up there was more dust inside along  with what looked like cotton. 
These are 6′ off the ground.  I cleaned them out. 
 
 This morning there is more cotton inside.    I did see a small yellow jacket carrying cotton like material on the mason bee structure.  After cleaning it out several times and perhaps because the weather has become cooler the cotton is no longer showing up inside.   I actually saw a yellow jacket carrying a tuft of cotton like material.  Please let me know if I should bring the two houses into the garage until it the yellow jackets are gone for the year.

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!

Taking the whole nest in is always good management.

Hi there,
These may be the beneficial wasps.   The crop of bees this year is terrible as the weather this last spring was awful.

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.

Winter is hibernation time
