I'm preparing to venture out on a daunting task. A neighborhood guy has a martin gourd that has been inhabited by a colony of bees. He wants it gone. 16' up on a metal pole with several other gourds. The pole is too flimsy to be scaled with a ladder. I wish I had a trained monkey .... I also am still trying to get a bee-vac built so I can capture 3 tree colonies. The number keeps climbing. I don't know if the feral bees are multiplying or people are just starting to pay more attention to the bees, or if they are just discovering that I'm keeping bees.
