scent

Probably pheromones in the soil or the natural urge to investigate other species nests. Just think that the bees see freshly dug soil and may think an interloper is making a nest site

Bees and soil

A couple of possible suggestions:

1) you are digging iover their existing nest site and they are struggling to orientate to find their nest burrows

2) Your visitors may be Red Mason-bees (Osmia rufa) which use damp soil (preferably with a clay content) for making the seals on their brood cells and for the nest closure plug.
