Pests of Honey Bees

Bee louse tunnels in honey cappings

Picture 3 of 15

The louse lays its eggs on the cappings of honey storage cells from May through July. Upon hatching, the young burrow into the cappings. As the larvae grow, their tunnels lengthen and broaden. The infestation is easiest to observe. The larva pupates inside the tunnel. Soon after emergence, the young adult crawls upon a bee.
