The much-maligned insects serve as predators, act as pollinators and help disperse seeds, among other useful functions.
What do wasps and hornets do for the environment?

Multiple stings by hornets (other than V. crabro) may be fatal because of highly toxic species-specific components of their venom. The stings of the Asian giant hornet ( V. mandarinia) are among the most venomous known, and are thought to cause 30–50 human deaths annually in Japan.

Why do hornets sting?
Hornets have stingers used to kill prey and defend nests. Hornet stings are more painful to humans than typical wasp stings because hornet venom contains a large amount (5%) of acetylcholine. Individual hornets can sting repeatedly; unlike honey bees, hornets do not die after stinging because their stingers are very finely barbed (only visible under high magnification) and can easily be withdrawn, so are not pulled out of their bodies when disengaging.

What is a night wasp?
Also, a related genus of Asian nocturnal vespines, Provespa, is referred to as "night wasps" or "night hornets", though they are not true hornets. Some other large wasps are sometimes referred to as hornets, most notably the bald-faced hornet ( Dolichovespula maculata) found in North America.
What chemical is used to sting hornets?
In the case of the Asian giant hornet ( V. mandarinia ), this is also used to mobilize many workers at once when attacking colonies of their prey, honey bees and other Vespa species. Three biologically active chemicals, 2-pentanol, 3-methyl-1-butanol, and 1-methylbutyl 3-methylbutanoate, have been identified for this species. In field tests, 2-pentanol alone triggered mild alarm and defensive behavior, but adding the other two compounds increased aggressiveness in a synergistic effect. In the European hornet ( Vespa crabro) the major compound of the alarm pheromone is 2-methyl-3-butene-2-ol.

Yellowjackets mostly scavenge dead insects to feed their offspring, meaning they prevent the bodies from piling up—like a cleaning service. Unfortunately, their scavenging habits and love of sugar puts them in close proximity to people, which almost never ends well for the yellowjacket or the person.
What do paper wasps eat?
The researchers found that wasps and hornets feed on late-season grapes, which are rich in wild yeast. The yeast survives the winter in the stomachs of hibernating queen wasps and is passed on to their offspring when they regurgitate food for their young. The new generation of wasps then carries the yeast back to the next season's grapes. So, raise your glass to the wasps and hornets.

Wasp workers toil ceaselessly to raise their sister workers from eggs the queen lays, cooperating and communicating in intricate ways to build and defend the nest, collect food and look after the queen. When the colony is large enough the workers start to give some young larvae more food at a much greater rate than usual, triggering genetic switches that cause the development of a potential queen rather than a worker.
