With autumn just around the corner, cooler weather, vibrant foliage, and the appearance of brown marmorated stink bugs await residents in 47 states.
Although the U.S. is home to over 200 species of stink bugs, the brown marmorated variety is a more recent arrival. First discovered in Allentown, Pennsylvania, in 2001, these pests have redefined the term 'invasive species,' causing significant damage to crops, native plants, and even infiltrating homes.
Once stink bugs find their way inside, removing them becomes a challenge. The most effective approach is to prevent them from entering your home altogether. Here’s how you can achieve that.
What exactly are brown marmorated stink bugs?
Adult brown marmorated stink bugs (commonly called “stink bugs”) measure between 1/2-inch and 1-inch in length, feature a shield-like shape with striped antennae, and display a marbled brownish-grey hue (the term “marmorated” refers to their marbled appearance).
When disturbed or crushed, they release a scent often likened to cilantro—if it’s noticeable at all. Thankfully, they don’t bite, sting, or harm your home’s structure. However, they are capable of flying.
What drives stink bugs indoors during autumn?
Annually, stink bugs enter a dormant phase in their life cycle, similar to hibernation, which occurs throughout the winter. To prepare for this, they seek shelter in the fall—typically from late September through October.
Once a stink bug identifies your home as a suitable seasonal refuge, it releases a chemical scent to attract others. Surprisingly, they aren’t looking for warmth and can’t predict how cold your house will become during winter. Their sole focus is securing shelter.
Effective Methods to Prevent Stink Bugs from Entering Your Home
To keep stink bugs from invading your home, you must seal their potential entry points, such as cracks, gaps, and crevices. Here are some strategies to achieve that:
Inspect your home’s foundation for cracks and seal any discovered gaps
Apply caulk to both the interior and exterior of your windows
Install weatherstripping around entry doors or add door sweeps if light is visible around the door edges
Clear debris and vegetation accumulated around your home’s foundation
Cover or screen the chimney opening if your home includes a fireplace
