At a Glance
Yellow jackets are aggressive stinging wasps that nest underground and in cavities. Late-summer colonies are large, so nest removal is best left to professionals.
Quick Facts
- Look: Black and bright yellow, stout body
- Nest: Underground, wall voids, cavities
- Concern: Aggressive; can sting repeatedly
- Peak: Largest and most defensive in late summer/fall
What Are Yellow Jackets?
Yellow jackets are stout black-and-yellow wasps that nest out of sight in the ground, in wall voids, and in other cavities. A nest entrance can be a small hole in the lawn or a gap in a wall.
Early in the season colonies are small, but they grow through the summer and can hold thousands of workers by late summer and fall.
Why They Are a Problem
Yellow jackets are far more aggressive than paper wasps, especially near the nest and late in the season.
- They defend nests vigorously and can sting repeatedly.
- Mowing or stepping near a ground nest can trigger a mass response.
- In late summer they scavenge sweets and meats around trash and patios.
- Stings are dangerous to people with allergies and painful for everyone.
How to Handle Yellow Jacket Nests
Because nests are hidden and colonies are large and defensive, do-it-yourself removal is risky. Professional treatment is the safest approach for most nests.
- Watch for steady traffic in and out of a ground hole or wall gap to locate the nest.
- Do not block a wall-void entrance, which can drive wasps indoors.
- Keep trash sealed and clean up food and drinks outdoors in late summer.
- Have active nests treated professionally, particularly near walkways or for anyone allergic.
Treat Safely
Professional treatment handles large, defensive colonies without driving them indoors.

Common Questions
How are yellow jackets different from paper wasps?
Yellow jackets are stockier, nest in hidden cavities and underground, and are much more aggressive, especially in late summer. Paper wasps build open nests under eaves and are generally less defensive.
Why are they so aggressive in late summer?
Colonies reach their largest size and food becomes scarce, so workers scavenge widely and defend the nest fiercely, raising the chance of stings.
Should I treat a yellow jacket nest myself?
It is risky. Hidden nests and large, defensive colonies make professional treatment the safest choice, especially near walkways or if anyone is allergic.
