Why is it called a "stink bug"?


When a stink bug wants to avoid predators, it will release a foul smelling chemical. They also have other not-so-delightful chemical scents they will release to attract other stink bugs. Once the little buggers have found themselves a cozy winter shelter, they will release more odors to gather/attract even more stink bugs.

The stink bug, as it is often referred to as, is originally from Asia and has made its way into the United States. Montana is actually the 47th state this nasty bug has established itself in. The stink bug is incredibly harmful to a handful of different things, luckily they are not harmful to humans.
