What type of animal eats harmful insects?

Many animals help control harmful insect populations, including birds, bats, and certain reptiles. For example, insectivorous birds like swallows and warblers consume large quantities of insects, while bats are known for their ability to eat vast numbers of moths and other pests at night. Additionally, amphibians such as frogs and toads also play a role in keeping insect populations in check. These natural predators contribute to maintaining ecological balance by reducing the numbers of harmful insects.
