I received a call from our neighbor who had a huge wasp nest 20ft up in a tree by their backyard patio. I used the Gotcha Sprayer Pro Flash adapter and a 22ft extension pole. First I tapped the nest, just to see what type of reaction I would get and boy did I get a reaction. In just a few seconds the wasps came flying out of the nest and started violently stringing the unit over and over again. I filmed the attack using a GoPro mounted to the extension pole. I attached an aerosol can of wasp and hornet spray to the adapter and after steadying the pole was able to kill the entire nest with my feet firmly on the ground and with less than 1 can of spray. This would have been a disaster if I were standing on a ladder.
