Bumblebees usually live in hollow spaces underground where they will raise larvae and store food. They sometimes also nest in birdhouses, bales of hay, or building walls. They particularly like the stuffing of old furniture or car seats and may thus move into junked cars or dumped upholstered furniture.
Unlike honeybees, bumblebees store only a few day's food and so are much more vulnerable to food shortages. Bumblebee nests are not carried through the winter. The last generation of summer includes a number of queens which overwinter separately in protected spots.1
Bumblebees are in danger in many developed countries due to habitat destruction and collateral pesticide damage.
In Britain, there are 21 species of native bumblebee and six varieties of cuckoo bees - bees that dupe other bumblebees into looking after their young. Of these, only six bumblebees remain widespread. Five are in serious decline and at least three are extinct. 1
