Why are the majority of wasps and hornets considered beneficial to humans?

The majority of wasps and hornets are considered beneficial to humans primarily because they serve as natural predators of pest insects, including species like mosquitoes, flies, and various agricultural pests. By preying on these insects, they help to control their populations, which can reduce the need for chemical pest control methods. This biological control is an essential aspect of maintaining the balance in the ecosystem and promotes healthier environments for both plants and animals.

In urban and agricultural settings, the role of wasps and hornets as pest management agents can lead to increased crop yields and better overall plant health, thus benefiting the food supply for humans. Their predatory behavior contributes significantly to pest regulation, making them an important part of integrated pest management strategies. This understanding underlines their ecological importance and positions them as beneficial organisms in various ecosystems.
