Where I live, Yellow Jackets nest in the ground. You'll be mowing the lawn and the next thing you know, you're under attack. I take care of those myself by pouring gasoline in the hole. It's always done the trick. Gasoline works fine, as does kerosene, which is safer. However, if you really want to try a cool way to do it - and a much more environmentally friendly way - go out there at night, toss a piece of dry ice over the hole, and then place a bucket over the dry ice. The carbon dioxide displaces the air in the nest and suffocates them with no harmful residues or risk of fire. Or, as Jesse Pinkman would say, "Yo! It's science, bitch!" Sounds good. How do I get my ice maker to spit out some dry ice?
