Stink Bugs: A Fall Invasion in Missouri

ST. LOUIS - As the weather cools in Missouri, residents are bracing for the annual influx of stink bugs seeking refuge indoors. While these unwelcome guests pose no threat to human or animal health, their presence can quickly become a nuisance.

According to Jay Everitt, technical director for Rottler Pest Solutions, stink bugs spend the warmer months in agricultural areas, where they can damage crops. As temperatures drop in the fall and winter, they migrate towards homes in search of warmth.

Fortunately, these insects are not dangerous. Michigan State University confirms that stink bugs do not bite, sting, or reproduce inside homes. Their primary defense mechanism is a foul odor, which can persist for hours if the bugs are crushed.

Experts advise against using pesticides indoors, as they are generally ineffective once the bugs have entered a home. The most effective strategy is prevention. This involves sealing potential entry points to prevent the bugs from entering in the first place.

Missourians should also be aware that stink bugs are not the only pests seeking shelter. Boxelders, spiders, Japanese lady beetles, and ladybugs may also attempt to enter homes during the colder months.

BNN's Perspective: While the arrival of stink bugs is undoubtedly an inconvenience, it's reassuring to know they pose no health risks. Proactive measures like sealing cracks and crevices are a sensible approach to minimizing their presence. This preventative strategy is a practical and environmentally conscious way to manage this seasonal annoyance.
