For pest control

Naturally occurring mantis populations provide plant pest control. Gardeners who prefer to avoid pesticides may encourage mantises in the hope of controlling insect pests. However, mantises do not have key attributes of biological pest control agents; they do not specialize in a single pest insect, and do not multiply rapidly in response to an increase in such a prey species, but are general predators. They eat whatever they can catch, including both harmful and beneficial insects. They therefore have "negligible value" in biological control.

Two species, the Chinese mantis and the European mantis, were deliberately introduced to North America in the hope that they would serve as pest controls for agriculture; they have spread widely in both the United States and Canada.
