We recently had a tree removed and in the process, uncovered a large underground bee hive. The tree guy put some additional dirt on it, hoping it would take care of the bees. Well, it didnt. Those little bastards just made themselves a hole in the dirt to go in/out. I saw a few things online, such as a slow drip of gasoline or emptying a can of bee/wasp spray down the hole. Any ers have some advice?
