Brown Marmorated Stink Bugs
As the evenings start to turn cooler, those darn stink bugs will be coming out of the trees and bushes looking for a warmer place to roost and overwinter.
Originating from China, stink bugs were initially discovered in the US in Allentown PA in 1998. They are found mostly in eastern PA, but have been regularly spreading throughout the eastern United States.
Stinkbugs have an armor like shaped body which varies in color from light beige to dark brown. They have scent glands situated on the bottom of its thorax and on its belly which produces a strong odor as a defense mechanism, therefore the name stink bug. As the weather starts to turn cooler, especially in the evenings, they start to move to overwintering sites generally into homes and other secured structures. They can flatten themselves as thin as a sheet of paper to gain access so sealing up your house is a good defense. Fix any damaged screens on windows or doors, use silicone-latex or silicone caulk to seal in the cracks around siding, doorframes and if there are any other openings. Remove window air conditioners, an easy and common entry point for stink bugs. Check your siding and soffits for any loose or missing pieces and seal up any cracks. We can also spray the exterior of your home as a deterrent to keep them from roosting on your house.
If they do find a way into your house, don't panic. They do not harm humans or create structural damage. They don't multiply while overwintering and if they do come into your living space will die with 24-48 hours. You can remove them by using your hand or use a shop vac or vacuum cleaner to remove them.
