The brown marmorated stink bug, Halyomorpha halys, was introduced to the United States from Eastern Asia in the mid-1990s. It is considered an invasive species as it was brought to United States soil from a foreign source. The Brown Marmorated Stink bug was first discovered in Allentown, PA in the fall of 1996, but was not properly classified until 2001. By the summer of 2004, the stink bug had rapidly spread across the east coast spreading through Virginia down into the southern states around the North Carolina border. Today, most of the Brown Marmorated Stink Bugs are concentrated in the mid-Atlantic region, but they have invaded and properly identified across 44 states.
As you can imagine the brown marmorated stink bug is a very smelly insect. The term “stink bug” comes from the release of a putrid odor when the stink bug disturbed or when crushed. While many other insects share this same defensive trait, the brown marmorated stink bug is the most prevalent and the smelliest of all these insects.
Stink bugs descriptions are hard to nail down as they have been sighted and recorded all across the world. Stink bugs have been described as both “shield” shaped and “ovular” insects. Adult stink bugs are almost as wide as they are long, and are roughly 2 cm in length. Their brown coloring is typically lighter on the antenna and darker on their shell like bodies. The muted colors and odd shape of the stink bug has resulted in a wide variety of descriptions and classifications for this stinky invader
Stink bugs favorite season is the fall. This is when they invade homes in large droves to seek shelter from the impending winter. While finding a lone stink bug can be alarming, homeowners should not be concerned until they find large numbers of live or dead stink bugs. An obvious sign of infestation is damage to gardens or crops as stink bugs tend to feed in droves. In addition, stink bugs can typically be found in sunny areas of a home as they require sunlight to maintain their body temperatures.
If you suspect that an infestation has developed inside your home or property, your best practice is to contact a professional pest control company to eradicate your invasion, stink free.
