Last night, I was working at a site which has been overrun by brown marmorated stink bugs- they seek the warmth of the office, and occasionally make their presence known by taking flight. Whenever I get an opportunity to smash one of the little buggers, I gleefully take it (they're invasive, there's nothing wrong in playing SMASHY SMASHY). When they are smashed, they release a scent which is often compared to that of cilantro. I think the smell is reminiscent of camphor... oddly enough, I don't find it all that unpleasant.
I was in sheer bliss last night, I must have smashed half a dozen of the little perishers. It's the little things that make you truly happy, even the little smashed things around the office.
