DC overrun with stink bugs.

I remember when they used to be called "congressmen." From NBC:

Smelly, pesky bugs known as stink bugs have been swarming the Washington, D.C. area -- and when you try to kill them, they just smell worse.

"When you try to kill them, before death, they stink," said Michael Raupp, an entomology professor at the University of Maryland. "They want to find a place to chill out for the winter. They're not coming in for warmth, they're coming in for refuge.

"They'll invade your attack and come in for the winter time. But on a nice warm day in February, they're going to say, 'Oh, spring,' and come down and be all over your windows and your baseboards and things like that."

Some frustrated area residents have gone as far as using their vacuum cleaners to combat these stinky critters. Scientists call their kind halyomorpha halys. They smell so badly because when threatened, they release a smelly defensive chemical.
