Why Are Stinging Insects More Aggressive in Fall?

Ah, autumn—so many things to look forward to, including tailgating for University of Michigan football games. However, this season also brings an increased presence of stinging insects, and their behavior is increasingly aggressive. Yet why is it that their population size increases and their behavior changes? At Frame's Pest Control, Inc., our Associate Certified Entomologists have compiled useful information to protect you from painful stings and prevent stinging insect infestations.

Reasons Why Stinging Insects Are More Aggressive in the Fall

During winter and spring, stinging insects are known to hibernate. Once summer comes, their hive size has increased, reaching living capacity. Therefore, when fall arrives, you’re dealing with mature hives that contain more foragers. The increased presence of stinging insects means that there are more chances you will be stung by one if you’re not careful.

One of the reasons for the increasingly aggressive behavior of these insects is that during this time of year, the hive is preparing its queen for winter. Therefore, they are more protective around the hive. Additionally, food is scarcer during the late summer and fall months, which is why you’ll see these insects go through dietary changes. Where they once sought protein, they now go in search of carbohydrates. This is why you’ll see an increased presence of stinging insects at picnics, barbeques, and outdoor social gatherings that are rife with juices, sodas, breads, and other carb-heavy foods. These dietary changes are also due to a decrease in food sources available, making these insects more competitive as they forage for food to bring back to the hive to sustain the winter months.

How to Prevent Stinging Insect Infestations

During the fall, we typically do a lot of yard maintenance as the leaves change colors and slowly fall from the trees. However, this maintenance also exposes plenty of places for stinging insects to build nests and hives.

The best way to prevent a stinging insect infestation is to get ongoing treatment throughout the summer to help prevent the population from getting too large. Additionally, the queen will depart the hive during the winter to nestle in a crack or void in a building. Therefore, treating the nest before this happens will reduce the likelihood that hives or nests will be built on your property the following year.
