Pest Description


Every creature on the planet has a role to play in the survival of their ecosystem. This even goes for pests we hate having around – especially those with an annoying bite or painful sting. Insects like bees and wasps do a lot for the environment, whether they’re pollinating, scavenging, or acting as food for other animals.

During the warmer months in states like Georgia and Tennessee, you’re more likely to come across stinging insects. While they’re not normally aggressive, this doesn’t mean you won’t be stung. Before you go buy the largest can of insecticide you can find, it’s important to know what you’re dealing with and the potential environmental impact your decisions could have.

Often mistaken for bees, due to their yellow-and-black coloring, yellow jackets are actually wasps. At about 1 1/2 inches long, they triple the average honey bee in length. Although the end of the warm-weather months means larvae production stops and males die off after mating, the yellow jacket is at its most active during the late summer in Wisconsin.

Yellow Jacket Fall Frenzy

Food becomes scarce as flowers are no longer in bloom. Like us, wasps get cranky when they’re hungry. They become more aggressive, stinging with even the slightest provocation. In their desperate search for food, they explore every possibility — including the folds of human skin. The yellow jacket will sting, often multiple times, when a victim bends a limb and squeezes the insect at the crook of an elbow or behind a knee. The wasp’s sting is very painful, not to mention dangerous to those with sensitivities. The anaphylactic shock from bee and wasp stings kills as many as 50 people in the U.S. annually.

Yellow Jacket Nests

Of the two varieties of yellow jackets in the state, the German yellowjacket prefers to construct its nests inside building walls. Yellowjackets nests are at their largest at summer’s end and can also be found in trees, shrubs, or underground. Indoor nests, which are especially tricky to remove, allow these wasps to remain active through the end of the year. And while yellow jackets don’t reuse their nests, instead of building new ones in the spring, it’s important to get rid of them. Old, abandoned yellow jacket nests attract other kinds of pests.

What You Can Do

In most cases, it’s best to avoid bees and wasps entirely, as they are normally not a danger to humans. However, when their nests are in close proximity to us, they are more likely to perceive a threat and defend their nest at all costs. Additionally, in the late summer months, some bees and wasps become more aggressive in seeking out food like sugar and fruit, which can bring them into contact with you and your family. If you decide to use pesticide or chemical sprays, keep in mind they can be extremely poisonous and should never be used indoors or near other people.
