well, for most bugs, it's stomp, but for wasps, it's stomp and drag, cuz they tend to still be alive and crawling around, even when they;re in 7 different pieces.
Its bad karma to step on bugs on purpose, so for the last 10 years or so, I have tried to avoid killing anything... (except homeless people... just kidding). I like wasps... I freak people out in the office by catching them and releasing them out the window... fully unharmed... I have only been stung doing this once in the last 7 years and that was in a callous on my finger from guitar playing, so i didnt even feel it!
