🐝 WHY DO WASPS BECOME MORE AGGRESSIVE LATER IN THE SUMMER?
Ever notice that wasps and yellow jackets seem to become a lot more noticeable—and a lot less friendly—as summer starts winding down?
There's a reason for that!
Earlier in the season, wasp colonies are focused heavily on building the nest and raising their young. As the colony grows, there are more workers actively protecting the nest and searching for food.
Later in the summer:
🐝 Colonies are at their largest. More workers means more activity around the nest.
🍬 Food sources start changing. As natural food sources become less available, yellow jackets are often attracted to sugary drinks, fruit, garbage, and other food around people.
🏠 Nests are well established. Wasps and yellow jackets become highly protective of their nests, especially when they feel threatened.
🚶 We're spending more time near them. Outdoor gatherings, decks, patios, and garbage areas can put people directly in their territory.
That's why a nest that seemed relatively quiet earlier in the summer can suddenly become a much bigger problem.
⚠️ Don't try to knock down or disturb an active nest yourself. Wasps and yellow jackets can defend their colony aggressively when they feel threatened.
If you notice increased stinging insect activity around your home or business, it's best to have the nest professionally inspected and treated.
Enjoy the last days of summer—just give those wasps a little extra space! 🐝
