Phantom does not provide a quick knock down. Please check out our article "How to Get Rid of Yellow Jackets". If you can get to the openings where the yellow jackets are coming in and out from we highly recommend applying a dust like Tempo 1% Dust and when the yellow jacket comes in contact with it, the dust will transfer from yellow jacket to yellow jacket and kill off the entire nest. Be sure to make your application in early morning/late evening when they are less active. You can also use Wasp Freeze for any straglers.
