Only female bumblebees can sting and they will only do so if they feel very threatened. [4] Britain adopted the Environmental Stewardship scheme with the goal of enhancing the supply of pollen and nectar sources for bumblebees. [7] Honeybee pollination has been seen to decrease as the season progresses due to decreasing temperatures, while pollination of bumblebees usually remains relatively constant. [1] Bumblebees tend to be more effective pollinators than honeybees since they can fly at lower temperatures. [1] B. ruderatus is commonly found in sympatric distribution with B. hortorum, but the latter has seemed to be unaffected by fragmentation, since it is still relatively commonly in Britain.
