As a Midwest homeowner, you're no stranger to the many pests that can invade your home throughout the year. One such unwelcome guest is the brown marmorated stink bug (BMSB), an invasive species that has been causing a stir in our region since its arrival in the late 1990s. In this comprehensive guide, we'll walk you through the essentials you need to know about these pesky invaders, from identification to prevention and control, brought to you by Spidexx Pest Control – your trusted partner in keeping your home pest-free!

Meet the Brown Marmorated Stink Bug

Originally from Asia, the brown marmorated stink bug made its way to the United States in the late 1990s, likely hitching a ride on shipping containers. This shield-shaped bug measures about ½ to ⅝ inches long and has a marbled brown appearance, which helps it blend in with tree bark and other natural surfaces. It gets its name from the unpleasant odor it releases when threatened or crushed – a smell often compared to dirty socks or cilantro.

While BMSBs don't pose a direct threat to humans, they can be a significant nuisance in large numbers, especially during the fall when they seek shelter inside homes to escape the colder temperatures. Additionally, they can cause damage to crops and ornamental plants, making them a concern for both homeowners and farmers alike.

Identifying a BMSB Infestation

The first step in dealing with a BMSB infestation is accurately identifying the culprit. Here are some key characteristics to look for when identifying a brown marmorated stink bug:

  • Marbled brown color
  • Shield-shaped body
  • White bands on antennae and legs
  • Unpleasant odor when disturbed or crushed

If you spot these insects gathering on the exterior of your home, especially around windows and doors, you may be dealing with a BMSB infestation.

Prevention: Keeping BMSBs at Bay

As with most pests, the best defense against brown marmorated stink bugs is prevention. Here are some tips to help you keep these smelly intruders out of your home:

  • Seal entry points: Inspect your home's exterior for gaps, cracks, or openings that could allow stink bugs to enter. Pay special attention to areas around windows, doors, and utility lines. Use caulk or weatherstripping to seal any openings you find.
  • Repair screens: Make sure window and door screens are in good repair, as BMSBs can easily slip through torn or damaged screens.
  • Install door sweeps: Add door sweeps to all exterior doors to help block any gaps where stink bugs could enter.
  • Maintain landscaping: Trim back vegetation near your home, as BMSBs often congregate on plants before making their way indoors.
  • Reduce outdoor lighting: Stink bugs are attracted to lights, so consider using yellow bug lights or turning off unnecessary outdoor lighting during peak stink bug season (late summer to early fall).

Control: Evicting BMSBs from Your Home

If you're already facing a BMSB infestation, don't panic! While they can be a nuisance, there are several ways to take back control of your home:

  • Manual removal: If you spot a few stink bugs inside, use a tissue or paper towel to gently pick them up and dispose of them outside. Avoid crushing them to prevent releasing their unpleasant odor.
  • Vacuuming: For larger infestations, use a vacuum cleaner with a hose attachment to suck up the stink bugs. Be sure to empty the vacuum bag or canister outside immediately after use to prevent the stink bug smell from lingering in your home.
  • Insecticides: While BMSBs are resistant to many common insecticides, Spidexx Pest Control offers professional treatment options specifically designed to target these stubborn pests. Our expert technicians will assess your situation and recommend the most effective solution for your home.
  • Long-term management: As part of our comprehensive pest control services, Spidexx Pest Control can help you develop a long-term plan to manage and prevent future BMSB infestations, giving you peace of mind and a pest-free home.
