A praying mantis cannot harm humans outside of small bites and scratches, but as they are not poisonous, these injuries don't hurt any more than an ant bite or rug burn. They are predators, and eat other insects, so in that regard they are helpful; while it is unlikely that they would get the opportunity to snack on a mosquito, they certainly would given a chance. They are more helpful than harmful, but in point of fact are really . . . neutral.

their predators are birds, lizards, bats, snakes and turtles
People buy praying mantis eggs because mantises are natural predators that help control pests like aphids, caterpillars, and flies in gardens. This organic pest control method reduces the need for chemical pesticides and promotes a more balanced ecosystem, leading to healthier plants.

They are named praying mantis because of their tyical "prayer-like" stance. The word mantis derives from the Greek word mantis for prophet or fortune teller.I also thin it came from back then when people would say "Don't Let The Bed Bugs Bite"
