If the intent is to kill the wasp, would a trap set to allow foragers to track through and return to the nest work? Killing the forager at least would be possible by taking a soda bottle and placing a piece of fruit in the bottom, turning it on it's side and placing d Carbyryl in the neck. Richard A.
