What Do Crickets Eat?


Crickets are omnivorous insect pests with a diet that primarily consists of plant matter, but they also consume other insects and organic materials. Understanding what crickets eat involves a breakdown of their diet into various categories:

  • Plant Matter: Crickets are known to consume a wide range of plant materials, including leaves, grass, fruits, vegetables, and flowers. They can be particularly destructive to crops if their populations are not controlled.
  • Decaying Organic Matter: Crickets are scavengers and will feed on decaying organic matter like dead insects, fallen fruits, and decaying plant material. This helps in the decomposition process and recycling of nutrients in the ecosystem.
  • Fungi and Algae: Crickets may also feed on fungi and algae, which can be found on plant surfaces or in damp environments. These sources provide essential nutrients, especially when their primary plant food is scarce.
  • Other Insects: Crickets are opportunistic predators and will occasionally consume other insects, including smaller crickets and insects caught in spider webs. This behavior can vary depending on the availability of prey.
  • Pet Food: In captivity, crickets are commonly used as feed for various reptiles, amphibians, and arachnids. They are often dusted with nutrient supplements to enhance their nutritional value for the consuming pets.
  • Protein Supplements: In some cases, crickets are provided with additional protein sources in captivity, such as fish flakes, cat food, or dog food, to ensure their health and nutrition.

The specific diet of crickets can vary depending on their environment and what is readily available to them. Their ability to adapt to different food sources is one reason for their success as a diverse and widespread insect species.

Do Crickets Eat Grass?

Yes, crickets do eat grass. Grass is one of the many types of plant matter that crickets commonly consume. Their diet can include a variety of plant materials, and grass, being a readily available and widespread plant, is often part of their natural diet. In addition to grass, crickets may also feed on leaves, vegetables, flowers, and other plant materials. This plant-based diet is a primary food source for crickets, especially in their natural habitat.

What Do Crickets Eat In The House?

When crickets find their way into a house, they typically feed on a variety of household items and organic materials. Here's what crickets may eat when they are inside a house:

  • Fabrics: Crickets are known to chew on fabrics made of natural fibers, such as cotton, wool, and silk. They may damage clothing, curtains, upholstery, and even paper products like books and documents.
  • Paper: Crickets may consume paper products, including cardboard, paper towels, toilet paper, and books. Their chewing on paper can result in significant damage, especially in storage areas.
  • Glues and Adhesives: Some crickets are attracted to glues and adhesives found in book bindings, wallpaper, and other household items.
  • Food Scraps: Crickets are scavengers and will feed on food scraps left out in the open. They are particularly attracted to crumbs and other small food particles.
  • Pet Food: Crickets may nibble on pet food left in open containers, especially if it contains grains or other plant-based ingredients.
  • Houseplants: If you have houseplants, crickets may feed on the leaves, stems, and other plant parts. This can be detrimental to your indoor garden.
  • Wood: Although less common, some crickets may gnaw on wooden furniture or fixtures. This behavior is generally rarer and less destructive than their consumption of fabrics or paper.

Crickets may enter homes seeking shelter, and their feeding behavior can vary. To prevent cricket damage indoors, it's advisable to keep food stored in airtight containers, seal cracks and gaps where crickets can enter, and reduce moisture in and around your home, as crickets are also attracted to damp areas. Additionally, maintaining a tidy living space can help deter crickets from settling in and finding sources of food.

Do Crickets Eat Spiders?

Crickets are primarily herbivorous, which means they primarily feed on plant matter and are not typically known for hunting or eating other animals, such as spiders. However, some cricket species may exhibit opportunistic or omnivorous behavior under certain conditions, especially if they are unable to find enough plant-based food. This can occasionally include consuming small insects or spiders, but it is not a common or typical part of their diet.

In general, crickets are more likely to eat decaying organic matter, plants, and even their species (cannibalism) in situations where food resources are scarce. If you are experiencing a spider infestation and are considering using crickets as a natural means of pest control, it's important to note that other methods, such as the introduction of spider predators or the removal of their food sources, may be more effective and humane.

Do Crickets Eat Cockroaches?

Crickets are not typically known to be predatory insects, and they primarily have a herbivorous diet, focusing on plant matter, decaying organic material, and occasionally small insects. While some cricket species may exhibit opportunistic or omnivorous behavior, it is not common for crickets to actively hunt or eat larger insects like cockroaches.

Cockroaches are generally considered a different insect group from crickets and are known for their scavenging behavior. They are more likely to eat a wide variety of organic materials, including food scraps, paper, and other detritus, rather than being a significant food source for crickets.

If you have a cockroach problem, it's typically more effective to address it using pest control methods specifically designed for cockroach elimination, as crickets are not reliable natural predators of cockroaches.

What To Feed A Cricket

Feeding crickets, especially when you are keeping them as pets or using them as live feeders for other animals, requires providing them with a nutritious diet to ensure their health and vitality. Here is what to feed crickets:

  • Commercial Cricket Food: There are commercially available cricket foods and gut-load products that are formulated to provide crickets with essential nutrients. These can be a convenient option for ensuring your crickets are well-nourished. These foods often contain a blend of grains, protein sources, and vitamins.
  • Fruits and Vegetables: Crickets can be fed a variety of fresh fruits and vegetables. Suitable options include carrots, apples, potatoes, lettuce, kale, and squash. These foods not only provide essential nutrients but also a source of hydration.
  • Grains: Dry grains like oatmeal, bran flakes, and whole wheat bread can be included in their diet. These are good sources of carbohydrates and fiber.
  • Protein Sources: High-quality protein is crucial for crickets, especially if you plan to use them as feeders for reptiles and other animals. Offer them fish flakes, dry cat or dog food, or commercial insect gut-load products to increase their protein intake.
  • Leafy Greens: Crickets can benefit from leafy greens such as spinach, Swiss chard, and collard greens. These provide vitamins and minerals.
  • Moisture: Ensure that crickets have access to moisture. This can be provided by placing a small dish of water, a sponge, or a source of moisture like fresh fruits and vegetables in their enclosure. However, be cautious not to make their environment too wet, as crickets can drown.
  • Calcium: Dusting the cricket food with a calcium supplement is important, especially if you plan to use them as feeders for reptiles. Calcium helps maintain the health of both the crickets and the animals that consume them.
  • Clean Food: Keep their food clean and fresh. Remove uneaten food promptly to prevent mold and bacterial growth in their enclosure.

Remember that the specific dietary needs of crickets may vary depending on their life stage (e.g., nymphs or adults) and their intended use (e.g., as pets or as feeders). Providing a varied and well-balanced diet is key to keeping healthy crickets that, in turn, can provide optimal nutrition to the animals that consume them.
