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.
Crickets can cause a lot of damage to crops. They eat the stems and seeds of almost all commercially grown plants, including corn, barley, wheat and vegetables. A large cricket population is capable of destroying rows of seedlings in a single day. When crickets invade a garden, they prefer to eat vegetables and fruits.
