@HarryNuggets it's worked for me 100% of the time all of the time. you do it at night because its cooler so they are dopey and they're all in the nest. spray liberally, they will start to come out but as they try to fly they will fall out of the sky because brake kleen has some shit in it that permeates their exoskeleton suit and gets to the meaty bits fast. you can even pick them off in the air with it and they will just drop lol
