Why Are Yellow Jackets So Aggressive in August and September?

If it seems like yellow jackets suddenly become more aggressive toward the end of summer, you’re not imagining it. August and September are typically some of the busiest months for yellow jacket activity in Massachusetts.

Why Yellow Jacket Activity Picks Up

By late summer, yellow jacket colonies have had months to grow and can contain hundreds or even thousands of workers. At the same time, their food sources begin to change. Yellow jackets become increasingly interested in sugary foods and drinks, which is why you may notice them around decks, patios, trash cans, outdoor meals, and cookouts.

Large colonies can also be very defensive of their nests. Accidentally getting too close to a nest, mowing over a ground nest, or disturbing an entrance can quickly result in multiple stings.

What Should You Avoid Doing?

If you notice heavy yellow jacket activity around your property, don’t start plugging holes or spraying into a nest entrance without knowing where the colony is located. Yellow jackets frequently nest underground, but they can also establish nests inside walls, siding, soffits, and other hidden spaces.

Disturbing a nest can cause the colony to become defensive. With nests inside a home, blocking their normal entrance can also cause yellow jackets to look for another way out.

Instead, keep your distance and watch from a safe location. A steady stream of yellow jackets entering and leaving the same spot is a good indication that a nest may be nearby.
