Why Ground Hornets Are a Problem Across King County
Whether it’s a Bellevue backyard barbecue or a Seattle office parking lot, ground hornets can quickly turn outdoor spaces dangerous:
- Residential Properties: Lawns, gardens, kids’ play areas, and dog runs are prime nesting spots.
- Commercial Spaces: Schools, HOA common areas, golf courses, athletic fields, and corporate campuses often have open soil and irrigation systems perfect for nests.
- Public Facing Businesses: Restaurants with patios, hotels, and daycare centers face customer safety risks and liability issues when hornets are present.
4 Sure Signs of a Ground Hornet Nest
| Sign | What to Look For |
|---|---|
| Heavy Hornet Traffic | Workers flying low, entering/exiting the same patch of ground |
| Dirt Mounds & Holes | Pencil- to golf-ball-sized entrances surrounded by loose soil |
| Constant Buzzing | Distinct sound coming from a concentrated area |
| Evening Clues | All hornets return home near dusk making entrances easier to spot |
Why DIY Hornet Control Can Backfire
For homeowners and property managers, attempting nest removal without the right tools can be dangerous:
- Risk of Multiple Stings Yellow jackets swarm aggressively when threatened.
- Missed Colonies Sprays or flooding often fail to kill the queen.
- Business Liability One sting incident can lead to bad reviews, tenant complaints, or workers’ comp claims.
- Regulatory Risks Some DIY products aren’t permitted for commercial use in Washington state.
The Safe, Step-by-Step Solution
- Observe from a Distance – Watch flight patterns to locate nests.
- Mark & Restrict Access – Rope off the area or post warnings for staff and visitors.
- Schedule Professional Removal – Licensed exterminators can treat at the safest time (late evening) and fully eliminate the colony.
