Management

Starter Cottages, available from my on-line Beediverse.com web site, are by far the best little box for use as a release box/emergence box.  I have tried all kinds of boxes, made from cardboard, plastic and wood.  Cardboard is too fragile and predators can get at the cocoons too easily.  Plastic sometimes overheats and is slippery for the bees to walk on while exiting.  Starter cottages are bee proof, can be washed for next year, and are relatively predator proof.  I usually place 100-200 cocoons per cottage.  One day before setting the cottage out into the field and adjacent to nests, I set the cottage out in the kitchen table. It gives the bees a head start on emergence.  I don’t want bees to fly around my kitchen, so I need a bee proof container= Starter Cottage.

I used this plastic container to carry 5 Starter cottages to the field site.   Each has about 100 cocoons.  The door to the cottage is secured with a pin, sometimes two.  The entrance hole is temporarily plugged with a cardboard straw until the starter cottages are set up in the yurt or other structure.  These Cottages have been out of the fridge and into a kitchen environment for 24 hours.  This means that some of the males will have emerged.

The D27 Yurt is set up with 9 Highrises in the upper part of the yurt.  Each Highrise has Eco-Corn Quicklock nesting trays with 72 nesting holes.  Note these Highrises do not have a cedar roof.

Starter cottages are set on top of each Highrise.
This is a Charly- Yurt containing many different
nesting trays, wood, plastic and eco-corn.

Once Starter cottages have been set in place,
the cardboard tube is removed.
Three males have emerged and are examining their new abode.   Note their long antennae- nearly as
long as their wings.
They now have to wait for the girls to appear.

“Hi Margriet,

I called you yesterday from the 16th/Oak community garden about a strange pest we found in our mason bee hive. They looked like larva with little red heads and were crawling over the cocoons in one of the trays. Do you have any idea what they might be from the attached images?
By the way I’ve read your book cover and cover and if I may be so bold I’d like to offer a small suggestion. Being a novice mason bee keeper I found it really hard to imagine and identify the pests you were talking about with the black and white drawings. Perhaps in future additions if budgets permit you could include actual photographs of the critters you describe? I’m sure the community at large would offer many for your book :) In all other respects that book was invaluable! 
I’ve also recently heard of people not using the bleach/water solution to clean cocoons but to use sand instead as an abrasive to remove mites. Have you or others ever tried the technique? 
Many Thanks,
Maria”
Hi Maria, 
Thank you for your pictures and comments.  
 Scavenger type beetle larvae.  Note size in comparison with 
mason bee cocoon in upper right hand side of picture.



Cscavenger type  Beetle larvae are reddish brown and can be recognized by their long bristles on each larval segment.



  • This pest is a carpet beetle (Page 90 Pollination with Mason Bees by M.D Dogterom.  These beetles feed on pollen provisions and nest debris.   
  • Yes, a book in colour would be awesome.  Like you mentioned, budget permitting.  It is definitely in the works for a future edition.
  • Yes, I have heard about the sand/abrasive technique to remove mites.  I have not used it myself.  I use a metal mesh as an abrasive surface to remove mites, and do a final rinse in bleach to remove any molds and parasitic fungi.  Using an abrasive surface like a metal screen works very well.  The sand is also used as an abrasive technique to scour mites from the cocoons.  I prefer not to deal with sand and find this a definite advantage.

The reason for setting out cocoons within the protection of a house that shelters nesting tunnels, is to provide the cocoons, and the mason bees inside, a place that is protected from predators like mice, protected from the sun and protected from rain and snow.

It depends on the design of the house whether cocoons can simply be set within the house, like underneath the roof of the Highrise or whether space needs to be created for the vial like in the Starter Cottage.
Royal house with predator guard

Temporarily remove predator guard from the front of the Royal house,
and set vial on its side, with tab removed,  underneath peaked roof.
 Replace predator guard.
The Royal house is similar to the Highrise.  Simply remove predator guard, and set vial on its side underneath the peaked roof.
If you have a Lodge- without the predator guard, or the Chalet with a predator guard, space needs to be created for the vial containing cocoons.  Remove one set of trays, insert vial above trays and replace vial with tray when all bees have emerged.
Lodge without predator guard.
Chalet with predator guard.
Unwrap bundle of nesting trays by removing electricians tape.  Remove
one set of trays, and re-tape remaining nesting trays.
The vial can now be inserted under the roof and adjacent to the nesting tunnels.

Replace the predator guard of the Chalet after vial has been set
inside the house.  When all bees have emerged- about 2 weeks
after first bees emerge, remove vial, tape up the individual tray
 and set above other trays.
If you buy a vial of Beediverse Mason Bee cocoons
from a store, the cocoons need to be set it out adjacent to mason
bee nesting tunnels.  Cocoons are
washed, screened and candled before packaging them into vials.
If you have a Starter Cottage
 with cardboard tubes it is best to set the vial of
cocoons inside the cottage amongst the nesting tubes.

Temporarily remove front door to access
cardboard tubes.

Remove a few cardboard tube to make room for one vial
containing mason bee cocoons.
Remove red tab covering the exit hole of the vial, and place
vial amongst tubes.

Replace front door and hang Starter Cottage on an East facing wall,
 in the sunshine and out of the rain.  This cottage can also be
 set down on a shelf.  Make sure it is secure so the wind
or predators do not knock it off the shelf.
Retail stores sell Beediverse mason bee cocoons in snap-cap vials.
Cocoons were harvested from nesting tunnels and cleaned. 

The Highrise contains Eco friendly Corn Quicklock nesting trays.
Setting cocoons above nesting tunnels makes it easy for bees to find their new nests.
Remove red tab that covers the vials’s exit hole,
and lay vial with cocoons in the attic and underneath
the roof.of the Highrise.
Loose cocoons harvested from nesting tunnels can also be placed
underneath the roof of the Highrise-”the attic”
Move cocoons towards the back. of the Highrise
so they dont roll out the exit gap.
Drop roof over attic in readiness for spring.

Emerged males are clustered on the outside of the emergence box waiting for females to emerge.





Close-up of emerged males on the outside of the emergence box.  Emergence hole of the box is visible below the hook.
The white clay  spots on the front of the emergence box are the first signs that bees have emerged.  Bees defecate this material as soon as they emerge. 


Dave uses stacked pieces of routered wood as nesting tunnels.  The emergence box removes the problem of predation during emergence.  Photo credits  Dave M.  Port Alberni.
