Just what are those giant bees that dig out piles of dirt in the ground and scare the living daylights out of you? Some people call them ground bees. Their real name is the Cicada killer. These ground bees do good by keeping those loud cicadas under control, but they are scary and big and ugly. So how do you kill these big bees? Bug spray, or should I say, wasp spray, or should I say bee spray. Usually I wouldn't advocate spray for bees, but in this instance because they a solitary type bee, I would say it is ok to sharp shoot them out of the air and then dust the holes they lived in with a good insect dust. Sometimes you are unlucky enough to have a bunch of these bees burrowing in your landscape, in this case you may have to hire a professional who can spray large areas, and remember, this may be a yearly thing for a while. Now go out and buy a good wasp freeze spray and happy hunting!
