Basics
Hornets are social insects, living in communities called colonies. They have a powerful venomous sting that causes allergic reactions in some people. In some cases they are pests, harming fruit crops and trees to obtain sugar and sap. In late summer, hornets are found around social areas and picnics, scavenging for food. Varieties such as the giant hornet can grow as large as 1 1/8 inches long, making them intimidating to those who startle them. However, hornets serve an essential function in the ecosystem. For this reason, hornets are considered protected wildlife in places like Germany.
Insect Populations
Hornets are predators that serve a special function in controlling other populations of insects. Without hornets, insects like spiders, caterpillars, flies, crane flies and beetles would breed out of control and become a greater nuisance. Hornets control the populations of these pests, eating them to obtain protein.
Pollination
Like the honey bee, hornets serve an essential function to fruiting and flowering plants. Hornets work to pollinate these plants so that they are able to flower with each growing season. Without hornets, pollination would not occur at the same rate, thereby stunting the growing cycle and affecting the food chain.
Considerations
Despite their benefits to the ecosystem, hornets are still considered a hazardous pest when they make their homes in or around places where people work, live or play. However, controlling the hornet population is only necessary when hornets pose a direct threat to people or domestic animals. When disturbed or provoked, hornets can become increasingly aggressive, causing a painful sting that may illicit an allergic reaction. Hornets serve an important function, and should be left undisturbed unless they pose a direct threat.
