The weekly podcast on all things creepy crawly with a focus on insects. Today we’re going to talk about stink bugs because my god there are tons of them right now.    In the fall when weather is starting to cool down a very smelly bug starts to make more and more of an appearance, but today we’re focusing on a specific stink bug called that the Brown marmorated stink bug. This bug is native to China, Japan, and other Asian countries but made its way into the United States in 1998. The state of introduction was Pennsylvania but this smelly bug can now be found throughout many states both east coast and west. Coincidentally it was also introduced into Europe in 1998, but I believe this came after the American introduction. For the European listeners you guys can find these in Germany, Turkey, Switzerland, Italy, Austria and much more recently the United Kingdom (gasp). They’re going to take over the world I’m sure except for Antarctica because well… who can actually stand to tolerate that wasteland. Now where you live might also have native stink bugs, so how can you tell the difference? The brown marmorated is a marbled deep brown in color. This is actually where the term marmorated comes from, and these ones have white bands on their antennae as well as a black and white stripes along the sides of their abdomen.   And yes this is indeed a true bug like all stink bugs and belongs to the family pentatomidae which is in reference to its pentagonal shape. The marmorated stink bug doesn’t only appear in fall though its life cycle begins in spring, but it takes a little while to reach their final form. For example they go through 5 instars or molts and each one takes a week or so to complete. They aren’t anything special to look at either, making them all the more unwanted by most everyone. They’re relatively small too, only reaching about 1.7cm or a little over half an inch, but their smell is incredibly strong, and is often compared with rotting vegetables. I mean if you’ve ever made one angry then I’m sure you know what I’m talking about. But why is it that we only seem to really notice them in the fall if they’re around all summer? These little dudes do not like cold weather, and as a result are actively trying to enter places that can shield them from the cold like your house for example. Or in my case the school that I currently work at because these things are everywhere, and the best part is that my school literally leaves windows open with no screens. They’re straight up asking for stink bugs and then freak out when they enter the school. But this episode isn’t about the dumb things that happen at my school. So now we know these bugs love the indoors when it gets cold, and are really smelly when threatened or scared, but are they bad for us?    Fortunately for you, this stink bug will not bite you, and isn’t harmful to you or your pets! Sure if your dog or cat eats one they might throw up later or get an upset stomach but the bugs are not poisonous or venomous so don’t go rushing them to the vet. Unless something is really wrong, but I haven’t heard of any deathly allergies to stink bugs. I did learn though that people who have an allergy to cockroaches will likely have adverse reactions to the brown marmorated stink bug, and these bugs can release a pheromone to let other stink bugs know they found a good place to hibernate for the winter leading to thousands of stink bugs in your home.
