Yellow Jackets are at Peak Aggression: By late summer and fall, yellow jacket nests have reached their maximum size, and the worker population is at its highest.
- Dwindling Food Sources: As natural food sources become scarce, yellow jackets become more desperate and seek alternative food sources, such as sweets and proteins from picnics, barbecues, and garbage.
- Behavioral Changes: The combination of a large population and dwindling food sources makes yellow jackets more aggressive and likely to sting without provocation.
How to stay safe
- Be mindful of nests: Yellow jackets often nest in the ground, so watch where you step and be cautious during yard work or running/biking thought fields.
- Aid Station folks-Cover food and drinks: Keep outdoor food, especially sugary items, covered to avoid attracting yellow jackets.
- Manage trash: Keep garbage cans sealed and clean up spills and food waste promptly.
- Wear appropriate clothing: Muted-colored clothing is preferable, and wearing closed-toe shoes, long pants, and long sleeves can help prevent stings.
- Move slowly: If a yellow jacket hovers near you, resist the urge to swat or run. Instead, move away slowly.
- Protect yourself in an attack: If you disturb a nest, run into a densely shaded area or a building, as wasps prefer bright sunlight.
- Be prepared for allergies: If you are allergic to stings, carry an epinephrine auto-injector and be prepared to seek immediate medical attention.
