what do crickets eat


Crickets, known for their distinctive chirping, are fascinating insects that play a crucial role in various ecosystems. Understanding what crickets eat is not only interesting from a biological perspective but also essential for those who raise crickets for purposes such as pet food or ecological research. This article explores the diet of crickets, offering insights into their feeding habits and preferences.

The Diet of Crickets: An Overview

Crickets are omnivores, which means they consume both plant and animal matter. Their diet is diverse and varies depending on their natural habitat and the availability of food sources.

Plant-Based Diet

  • Vegetation: Crickets commonly feed on leaves, fruits, and flowers. They are particularly drawn to decaying plant matter, which is easier to digest.
  • Seeds and Grains: They also consume seeds and grains, making them occasional pests in agricultural settings.

Animal-Based Diet

  • Insects and Larvae: Crickets are known to eat various small insects and larvae. This includes both living and dead insects, showcasing their opportunistic feeding behavior.
  • Carrion: They do not shy away from carrion (dead and decaying flesh), which provides a rich source of nutrients.

Feeding in Captivity

For those raising crickets, either as pets or as feed for other animals, understanding their dietary needs is crucial:

  • Commercial Cricket Food: Available in pet stores, this food is formulated to provide a balanced diet for crickets.
  • Fruits and Vegetables: Offering fresh fruits and vegetables can ensure crickets receive necessary nutrients and hydration.
  • Protein Supplements: To boost protein intake, especially for crickets being raised as pet food, protein-rich foods like fish flakes can be provided.

Water Intake

Crickets require a source of water for hydration. In captivity, this can be provided through wet sponges or fruits with high water content to prevent drowning.

Natural Predators and Their Influence

Crickets’ feeding habits are also influenced by their need to avoid predators. They are a key food source for various animals, including birds, reptiles, and small mammals. This predator-prey dynamic often influences their feeding times, leading them to be more active and feed during safer, nocturnal hours.

Ecological Significance

In the wild, crickets play a significant role in the ecosystem. They help in breaking down plant material, aiding in nutrient recycling. Their feeding habits also control the populations of smaller insects.


Crickets have a diverse and adaptable diet, making them a resilient species in various environments. Understanding their dietary habits is not only key for those raising crickets but also adds to the appreciation of these common yet often overlooked creatures. As a staple in the diet of many pets and wild animals, crickets continue to be an essential component of the food chain.
