ground bee problem
For the past 3-4 years I have an ever expanding colony of ground bees on an east facing slope in my garden in Boulder. The bees are just slowing down now from their maximum activity. The area had been vegetated before the bees, but now we an't get anything to grow there.
Any solutions. The bare spot is quite unattractive in a nicely groomed yard.

I am sending you a link to a CSU fact sheet about nuisance bees and wasps, but it does not address the damage to the ground. If the bees are gone, you can add amendments to the soil (compost) and then plant flowers or shrubs. But you should probably be sure that the bees are gone before working on the soil.
