sticky2 From Glenn M.  

Probably a silly question, since you install them on your houses – but do these not inhibit bees from entering? The majority of designs do not have any protection.

It’s a good question and the answer is not that obvious.  The predator guard has to have an entrance of about an inch across. Bees have no
problem in entering and landing on the face of the nest.  A guard for bird predator is obvious  But a secondary benefit and even more important benefit is that it appears to Lower the incidence of wasp parasitism. I believe this might be because the guard increases the wasps search time for its prey.before the female bee is back to the nest We do have a special on predator guards today until the end of the month.

From Carlos ”  When I was opening some of my bee boxes, I came across areas in which the cocoons and pollen were all stuck tightly together, as if glued by some sort of resinous substance.  They were so tightly bonded that some cocoons got shredded when I extracted them.  The trays themselves had to be pried apart.  i the photo the darkened areas mark the zones of stuck cocoons.  As you see, they don’t seem to be spatially related to the open ends of the trays, as if water or something was being introduced there.  I had several boxes like this among those that were at my alternate location, none at my home.  I have never encountered anything like this in the 15 years I have been doing this.  TIS a puzzlement!

Hi Carlos-Your story  reminds me of the resin bee.  The resin is sticky or less when cold, and quite brittle.  But I have only seen this resin in nesting tunnels about 4mm in diameter, not 7.4 mm or so.   Management wise,  I usually leave these cocoons in the nesting tunnels and let them emerge through the resin when it is softer and less brittle and tough like it is in the winter months..




It is harvest time!  It is time to take stock.  After harvesting cocoons and cleaning out mason bee homes and nests, assess what you need for next year.


Comparison to a penny.

A few more pics of those black grubs to better give you a scale. If you see these black grubs in your harvest, rinse with bleach.

Hi everyone- It is fall and I am catching up on posting all the lovely pictures and stories, including questions that you all have sent me.  Keep them coming.  Learning about bees other critters and the environment is a life-time learning process.  Have a great fall, and to our American cousins, a happy Thanksgiving.  Margriet

These pics are from Joe S.  Thanks Joe.  I don’t think these pictures need captions!!  Bird eggs are a great source of protein for bears.  Joe did ask me if I had heard of bears going after mason bee nests.  And yes, bears did chomp away at my mason bee nests once, when bee homes were located close to the mountains in bear territory.  It was spring at the time and the bear’s nose caught the scent of newly collected pollen and nectar.
