Buy some spray. They make spray just for that. The foaming kind works best and can shoot 20 feet. If there are any plants or flowers under where you are spraying I would cover them. Do it at night when they are not active. Just aim and spray. It will kill the wasp's in there as well as any that return to the hive after you spray it. Good luck. We have to go through this several times a year.
