Cicada Killer Wasps

I was reading in the paper this morning about Cicada Killer Wasps. They burrow into the ground. This hot dry weather we have been having has been perfect for them. They are called Killer Wasps but they actually never sting anyone. They have not found anyone who has been stung by one. They mind their own business and don't have hives so they have nothing to protect. Often a person gets bitten by a wasp because you have disturbed their nest. The ordinary wasp likes to build a hive along the soffit of your home. The usual wasp spray does not kill them either.
