I fill a garden sprayer with 1/4 cup dish washing soap and 2 gallons of water. At night, I go around and push the nozzel into the holes and give the holes a good flush. The bees come out and drop to the ground, dead by morning. Repeating this a couple times over their emergence/ mating time keeps the population, and new borings under control. I tolerate a few because I like to watch them in aireal battles in defending their territories. ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ + Raymond J.
