As the weather cools down in the fall, homeowners across the Midwest start to notice an unwelcome visitor: the brown marmorated stink bug. Originally from China, these invasive pests were first spotted in the US in the late 1990s and have since become common throughout the region.
They feed on various crops, including soybeans, apples, and pears, making them a concern for both homeowners and farmers.
According to experts, the “stink” in their name comes from a defense mechanism they use when threatened. “Avoid smashing stink bugs, as they release a foul smell,” explains Scott Schirmer, a manager with the Illinois Department of Agriculture.
While they are a nuisance, stink bugs don’t harm indoor plants or damage homes. Often, they remain unnoticed as they seek warmth inside.
So why do stink bugs invade homes? Kacie Athey, an entomologist with the University of Illinois, explains that stink bugs cannot survive extremely cold temperatures.
“In the summer, they thrive on fruits and vegetables, but as it cools down, they look for warm places to overwinter, and homes make the perfect shelter,” she says.
Homeowners might find stink bugs on screen doors or in hidden spots around the house. While pesticides may seem like an easy solution, experts advise against using sprays indoors. Pesticides are often ineffective and can leave harmful residue behind.
Instead, the U of I Extension offers practical advice for managing stink bugs:
Use a vacuum cleaner to remove them or drop them into soapy water.
Seal cracks and crevices around your home in early fall.
Repair windows and install door sweeps to prevent entry.
By following these simple steps, you can keep stink bugs at bay and enjoy the fall season without any unpleasant surprises inside your home.
