David Green states that gasoline is not the way to kill off a hive because of the carcinogenic effect of the gasoline, and its effect on the ground water. I believe David makes a good point. I will therefore take up the question of using gasoline with one or two local beekeepers who are supporters of the use of this product. What is the preferred way of killing off a hive.?
