How Long Do Hornets Live?
A hornet’s life varies depending on species. An average worker has a lifespan of approximately 12 to 22 days, while the queen can live up to a full year, meaning that fertilized queens are the only hornets actually to survive the winter.
Hornets can’t endure the cold, so if you spot a nest near your house, you can wait for the winter for them to die out. If you see hornets near your home, do not attempt to dispose of the nest yourself.
Hornets are incredibly dangerous, and while a single sting may be fine if you’re not allergic, many can become life-threatening. When a hornet dies, it releases a pheromone that will attract nearby hornets to come for aid, meaning you should avoid killing hornets nearby their nests at all costs.
An unattended nest will keep growing throughout the whole year, as the queen lays eggs during the summer. Hornets are known to nest inside walls and on wood ceilings. In such cases, you should call a professional to immediately deal with the problem, as hornets are very protective of their nests. Trying to deal with them indoors is incredibly dangerous.
