“FYI!  Our son, who is in Paris now, sent me this picture from a visit to a public demonstration garden,  “Hotel a Abeilles” designed for native bees.”
Yes a great structure for bees and for people to learn about bees.  Note:  Over several years, parasites and pest also increase unless old used bee logs and replaced with new ones.

Mason Bees and many other types of insects protect their offspring with casings of clay.  Who would have thought that a rounded piece of clay, would have such an interesting content!   Nothing is ever like it appears.  A great show and tell for the kids.


Possibly a type of beneficial wasp -all neatly lined up in a row.

Fungi-infected blackened mason bee pupae/grubs

dsc00004 This parasitic fungi is present in most regions and infects mason bee larvae during the spring/summer months.  Decrease the presence of this parasitic fungi by first washing and scrubbing and rinsing bee homes, nesting trays AND  mason bee cocoons in water  Then- ALWAYS -give these items a final rinse with bleach (4 litres/one gallon of water with 1/4 cup of bleach).

Caution: Prevent release of fungal spores  by not breaking the blackened pupae.  More information in the book “Pollination with mason Bees“.

Along with turkeys and cranberry sauce and lots of other good things, it is time to clean your mason bee homes and cocoons.

Lots of info on our Facebook page about washing cocoons, removing mites with a sieve and storing them safely over the winter.  After washing, dry cocoons on paper towels.  Pollen feeding mites that you can remove by washing under running water have 8 legs and are just about microscopic.  You can see them fairly well with a 10 x magnifying glass.

Margriet showing how easy it is to protect your new bees for next spring by placing your bee home into a wasp-proof net bag.

Wasp cocoon

Cocoons showing at least 4 developing parasitic wasps. You can see this in the fall when candling cocoons ovr a 6V flashlight.- and in a dark room.


Wondering why bees don’t emerge from their cocoons. In the left and center cocoons the developing bee pupae have died and have turned moldy. The right hand cocoon contains 5 developing parasitic wasps pupae. Through the summer, these wasps can cycle though to the adult stage and produce offspring every 3 weeks! PROTECT YOUR BEE OFFSPRING through the summer months with wasp proof netting.
