Bumblebees in a Nest Box

In nest boxes buried to attract deermice, queen bumblebees sometimes would find them first. It proved to be first-come first-served; neither species displaced the other. For insulation the boxes had an upper area separated from the nest chamber. In one nestbox both species used the same tunnel and box with the mice living in the upper portion. One evening in a box occupied by a colony of bees a one-way trap door was placed in the tunnel entrance and baited with sunflower seeds. When the box was examined the next morning the mouse that got trapped in the box had killed all of the bees.
