Crickets are omnivores and will eat fruit, seeds, leaves, other insects, nectar and parts of dead animals. While they are agricultural pests that will eat crops and seeds, this occurs rarely. Overall, crickets are not bothersome to humans.
What Do Crickets Eat? Like many insects, crickets are not picky eaters. As omnivores, they will eat both plant and animal matter. They also act as scavengers and will eat decaying animals and rotting vegetation. In times of desperation, crickets will also cannibalize other crickets, often targeting injured or weakened individuals. Mole crickets, a common lawn pest in the southeastern U.S., have a diet that focuses on worms, insect larvae, roots and grasses. Crickets kept as pets (or as food for other pets) are often fed lettuce and ground-up dog kibble. How and Why Do Crickets Chirp? Only male crickets chirp. They do so to announce their capability to mate.
