A scent emitted by the guards incites nestmates to attack, often resulting in multiple stings to victims. yellow journalism, the use of lurid features and sensationalized news in newspaper publishing to attract readers and increase circulation.
Baits containing growth regulators or entomopathogens are being investigated. In North America, they are also known as yellowjackets. Hatched larvae will then feed on the eggs, larvae, and pupae left unprotected by the wasp, sometimes destroying large parts of the nest as they tunnel throughout looking for food. The best way to kill yellow jackets in the house is to use a vacuum trap. However, it can be very useful for catching the queen in the late winter or early spring. If yellow jackets seem more aggressive than bees or hornets, it's for a good reason. By midsummer, the first adult workers emerge and assume the tasks of nest expansion, foraging for food, care of the queen and larvae, and colony defense. This has a serious effect on forest ecology, as less honeydew remains available for native birds.
