Stink Bugs in Seattle: What You Need to Know

Stink bugs, particularly the Brown Marmorated Stink Bug (BMSB), have become increasingly common in Seattle, especially during the fall and winter months. These pests are known for their shield-like shape and the unpleasant odor they emit when threatened or crushed. Understanding their behavior and how to manage them is key to keeping your home pest-free.

Identifying Stink Bugs in Seattle

The most common stink bug in Seattle is the Brown Marmorated Stink Bug (Halyomorpha halys). They are typically about ¾ inch long and mottled brown in color. Key identification features include:

• Shield-shaped body
• Banded antennae
• Smooth shoulders (as opposed to spiky)

It’s important to distinguish them from other insects. Misidentification can lead to ineffective pest control measures. You can find helpful images and detailed descriptions on reputable websites like Wikipedia’s entry on Brown Marmorated Stink Bugs.

Why Are Stink Bugs in Seattle?

Stink bugs are not native to North America. They were accidentally introduced from Asia. Seattle’s climate, with its relatively mild winters and warm summers, provides a suitable environment for them to thrive. They are attracted to lights and seek shelter indoors as temperatures drop.

Dealing with Stink Bug Infestations

Complete eradication of stink bugs can be challenging, but there are several effective methods for managing infestations:

• Sealing Entry Points: Seal cracks and crevices around windows, doors, pipes, and foundations.
• Vacuuming: Vacuum up any stink bugs you find indoors. Dispose of the vacuum bag immediately.
• Traps: Commercial stink bug traps can be effective, especially when placed near entry points.
• Professional Pest Control: For severe infestations, consider contacting a professional pest control service.

Avoid squashing stink bugs indoors, as this releases their unpleasant odor. Instead, gently sweep or vacuum them up.

Preventing Stink Bug Problems

Preventative measures are the best defense against stink bugs:

• Install screens on windows and doors.
• Repair or replace damaged screens.
• Keep outdoor lights off, as they attract stink bugs.
• Remove leaf litter and debris from around your foundation.
