If you can locate the holes they are going into, spray wd-40 into the hole using the attached straw, then step back! The female will fall out & be dead when it hits the ground. 2 years ago I sprayed & killed almost 40 of them. The following year there were very few around!

Spraying is the answer, but you want to do it at a time when the nest is full and the bees are inactive - at night when it is colder.
