One week ago I moved to Arnold, MD from New York state. Our new house has a problem with bees 1) residing in my porch in a dormant condition 2) swarming around our heads when the temperature reaches above 70 degrees 3) an apparent bee colony below the house, indicated by a pile of dirt with many holes While one person suggested eradication with poison, I am reluctant to do this. Any suggestions?
This is an unusual bee. We have sent along your photos to bee specialists for id. We will get back to you as promptly as possible. Meanwhile, please do not harm the bees. We can say that they are not one of the aggressive species.
This is Anthophora villosula, an important pollinator and a gentle solitary ground-nesting bee (also called a "digger bee") that likes to build its solitary nest under decks. They have very short lifespans. These bees are not aggressive/defensive. If you wish to deter these bees, you can seed lawn heavily with grass seed, since most digger bees like exposed soil and not grass.
