Face of a southern yellowjacket (Vespula squamosa)Yellowjackets may be confused with other wasps, such as hornets and paper wasps such as Polistes dominula.A typical yellowjacket worker is about 12 mm (0.47 in) long, with alternating bands on the abdomen; the queen is larger, about 19 mm (0.75 in) long (the different patterns on their abdomens help separate various species).
The eastern yellow jacket or eastern yellowjacket (Vespula maculifrons) is a wasp found in eastern North America. [1] Although most of their nests are subterranean, they are often considered a pest due to their nesting in recreational areas and buildings. [ 2 ]
V. squamosa is commonly called the southern yellowjacket. It was described by Dru Drury around 1770. [6] It is a member of the family Vespidae, which includes paper wasps (subfamily Polistinae), pollen wasps (subfamily Masarinae), potter and mason wasps (subfamily Eumeninae), and yellow jackets (subfamily Vespinae).

The Summary. Flooding in North Carolina following Hurricane Helene has led to swarms of yellow jackets. Heavy rain and standing water likely destroyed the insects' nests underground and in trees.
Over 90% of these trees contain live insects. Although V. pensylvanica typically resides in ground nests, queens occasionally choose these trees as overwintering sites. One potential strategy to reduce the number of yellowjackets and other generalist predators is applying preharvest permethrin sprays in combination with mechanical tree-shaking.

These new cells house the new queens and males. In the fall, the new queens begin hibernation, while the old queens die off and the colony collapses. In some cases, the nests may survive through the winter and reach the next season. If this occurs, the nest will become polygynous and reach a much larger size than in the previous year. [5]
