Yellowjackets in Eastern Tennessee
Found throughout the United States, yellowjackets are one of the most known types of wasps. These beneficial wasps live in colonies with thousands of individuals and would be a lesser threat to humans, were it not for their opportunistic behavior of nesting in structural voids, attics, and cavities associated with landscaping features. They also have a tendency to be aggressive and sting at will, which is why many tend to fear these stinging insects. Adult yellowjackets feed mainly on fruit juices and other sweet liquid materials, whereas their larvae are fed bits of soft-bodied insects like caterpillars and flies.
Yellowjackets often nest in different areas: there are ground nesters, which frequently use old rodent burrows and aerial nesters. Above-ground nests are found among the leafy branches of trees and shrubs and also on structures. Occasionally, the nest may be constructed on the side of a building, in wall voids, under eaves, crawlspace, and attics. The entrance of the nest is normally a hole located at the bottom. These aerial nesters don’t become scavengers in the fall, but they are extremely defensive when their nests are disturbed. Locating the nest, through observing flight patterns, is essential to eliminate them.
Yellowjacket Behavior & Stings
Yellowjackets are slow to sting unless their nest is threatened. They also will get more aggressive in the fall when their resources begin to deplete. The main threat is that yellowjackets are able to sting more than once due to their smooth stinger. A sting can cause a variety of reactions in people. Some individuals are more sensitive than others, due to allergic reactions, and should seek medical attention when stung.
Sometimes yellowjackets living in wall voids chew their way through the drywall and enter the structure’s living space. Naturally, the presence of large numbers of wasps flying around the room can be alarming to homeowners. If you notice a nest forming on or near your property, it’s important to contact your local wasp removal experts.
