Santa Clara Valley Beekeepers Guild
The Bumble bee is native to California and can be encouraged to pollinate your yard by giving some of them a local home. Being a social insect they live in a hive like the honey bee but the structure and life style are very different from the honey bee. A good honey bee hive may have 40000 bees but a Bumble bee hive will be closer to a hundred or so bees and they are more passive than the honey bee if you are worried about stings.
Their home is, in the most basic form, just a box will some upholster's cotton in it (not medical cotton). The box has a entrance hole and is placed in a protected place.
Since Bumble bees, except for the queens, do not live over the winter keeping these maintaining these bees year to year differs greatly from wintering a honey bee hive. Some members have or have had Bumble bees, so attend a meeting to meet someone with at least some experience with them.
There seems to be a lack of general infomation of "keeping" Bumble bees on the web, but here are some links to get you started:
They offer a book on the Bumble Bee and the "Humble Bumble Home".
A published paper on the subject that seems to be missing the figures but may be of interest.
A page that tells how to make a home for Bumble bees.
