Which product(s) you would use for wasp control is entirely dependent on where and how you are trying to treat for them. If you are looking for something to spray them as you see them flying around or where you have access to spray a whole nest hanging you could use a contact kill spray like Wasp Freeze. If you see they have a nest in a void of the home or in the ground that you can't spray directly, you would need to treat the entry point they are using with a dust like Delta Dust to allow them to take it back to rest of the population.
PT Wasp Freeze II Aerosol - 17.5 oz can be used for meat bees to kill on contact if sprayed directly.
1) Locate the nest. If you are not sure exactly where the nest is located, use a listening device to hone in as close as possible to the exact location.
2) Drill small holes directly into the nest from inside of the structure. If it is not possible to drill from the inside, the drilling can be done outside. If you do this, be sure to leave any outside entrance holes open until the beginning of fall when hatching is sure to be completed. Then the entrance may be sealed to prevent further nest establishment.
4) Seal any inside holes.
5) Repeat in 3 to 4 months to control for newly hatched yellow jackets.
