What are these small holes in my garden?

This is the home of a mining bee not a wasp, they are harmless solitary bees. Mining bees often live close to other mining bees. Its not its not uncommon to notice a dozen or more of their holes in close proximity.

Mining bees have a very short life usually a month or so, after emerging in late April to early May, the bees find a mate then lay eggs in the holes which emerge the following spring.

Mining bees are not a pest!!! they are valuable early pollinators and harmless to humans.

Please do not kill these or other solitary bees.

If you still have questions just give me a call :)
