Enjoying a summer barbecue on your Queen Anne patio or watching the kids play in your Bellevue backyard is one of the great joys of living in the Seattle area. But when an uninvited, buzzing guest arrives, it can quickly turn relaxation into anxiety. Is it a harmless bee just pollinating your flowers, or an aggressive wasp looking for a fight?
For Seattle homeowners, distinguishing between a beneficial pollinator and a potentially dangerous wasp is the key to staying safe. This guide from the local experts at Willard’s Pest Control is designed to help you identify the most common wasps in our area, understand their behaviors, and know when to call for professional help.
Are They Wasps, Bees, or Hornets? The Quick Seattle ID Guide
At a glance, it can be tough to tell these stinging insects apart. Here’s a quick guide to help you make a fast identification from a safe distance:
- Wasps:
- Body: Narrow, defined “waist,” smooth and shiny body.
- Legs: Noticeably long and dangle down during flight.
- Fuzz: Almost no hair or fuzz.
- Bees (e.g., Bumblebees, Honey Bees):
-
-
- Body: Plump, round, and fuzzy.
- Legs: Not as long or noticeable during flight.
- Fuzz: Covered in hair, which helps them collect pollen.
-
- Hornets:
- In our area, the primary “hornet” people see is the Bald-Faced Hornet, which is technically a large type of wasp. They are larger than most other wasps.
The “Big Three”: Common Wasps You’ll Find in the Seattle Area
While Washington is home to many insect species, you’re most likely to encounter one of these three in and around your home.
Yellow Jackets
If you have a wasp problem in Seattle, it’s probably a yellow jacket. They are notorious for their aggressive behavior, especially as summer turns to fall.
- What They Look Like: Classic black and bright yellow markings on a segmented, shiny body.
- Nesting Habits in Seattle: Yellow jackets are opportunistic nesters. You’ll find their concealed paper nests in wall voids of older Capitol Hill homes, in the ground of a landscaped yard, or even in attics and crawl spaces. Their nests can grow to house thousands of individuals.
- Behavior & Aggressiveness: Highly aggressive, especially when defending their nest. They are scavengers attracted to proteins and sugars, making them a common nuisance at outdoor gatherings.
- Local Tip: Watch for constant air traffic. If you see a steady stream of wasps flying in and out of a single hole in the ground, a crack in your siding, or an opening under your eaves, you likely have a yellow jacket nest.
Paper Wasps
Paper wasps are another frequent sight, easily identified by their unique nests.
- What They Look Like: They have a more slender, longer body than yellow jackets, with long legs that dangle conspicuously as they fly. They are typically brown or reddish-brown with some yellow markings.
- Nesting Habits in Seattle: Their nests are their most identifiable feature—a single, open comb of paper-like cells that looks like an upside-down umbrella. You’ll find these nests hanging from the eaves of homes from West Seattle to Redmond, as well as on porch ceilings, under deck railings, and inside unused BBQ grills.
- Behavior & Aggressiveness: They are less aggressive than yellow jackets and will generally only attack if they feel their nest is directly threatened. However, their sting is still painful.
- Local Tip: Perform a quick visual check of covered areas around your home in the spring. Spotting and removing these nests when they are small is much easier and safer.
Bald-Faced Hornets
Despite their name, bald-faced hornets are a large, formidable type of wasp. They are easily recognized by both their appearance and their impressive nests.
- What They Look Like: A robust, large wasp, primarily black with distinctive white or yellowish-white markings on its face and abdomen.
- Nesting Habits in Seattle: They build large, enclosed, gray paper nests that can reach the size of a football or even larger. These nests are often found in trees and large shrubs but can also be attached to the sides of buildings or under overhangs.
- Behavior & Aggressiveness: Bald-faced hornets are extremely aggressive and will defend their nest vigorously, often attacking in large numbers. Their stings are notoriously painful.
- Local Tip: If you spot a large, gray, football-shaped nest on your property, do not approach it. Keep children and pets far away and call a professional immediately.
Other Wasps You Might See in Washington
- Mud Daubers: These solitary wasps are identified by their long, thread-like waist and the mud tube nests they construct on the sides of buildings. They are non-aggressive and actually beneficial, as they hunt spiders.
- Cicada Killers: Their large size can be intimidating, but these ground-nesting wasps are focused on their namesake prey and are generally not a threat to humans.
When a Wasp is a Problem: Risks for Seattle Families and Pets
While most stings are just painful, they can be a significant health risk. In the United States, an average of 72 deaths from hornet, wasp, and bee stings occur each year, with 84% of those fatalities being males.
The primary danger is anaphylaxis, a severe allergic reaction. It’s estimated that up to 5% of the U.S. population has experienced a systemic allergic reaction to an insect sting. For those who have a known allergy, the risk is serious, and people who have had a severe reaction once have a 60% chance of a similar or worse reaction if stung again. This makes avoiding nests and seeking professional removal paramount for at-risk individuals.
Don’t DIY! When to Call a Seattle Wasp Control Professional
While a single wasp can often be dealt with using a store-bought spray, attempting to remove a nest on your own is a dangerous gamble. It’s time to call a professional if:
- You see a large number of wasps or a visible nest.
- Wasps are entering or exiting a crack or hole in your home’s walls.
- The nest belongs to an aggressive species like Yellow Jackets or Bald-Faced Hornets.
- The nest is in a hard-to-reach or elevated location.
- Anyone in your household has a known allergy to bee or wasp stings.
