Introduction
Crickets are fascinating insects commonly kept as pets, used as feeder insects for reptiles, or observed in gardens and homes. Understanding what crickets eat is essential to keeping them healthy and active. Proper nutrition not only prolongs their lifespan but also improves their breeding and overall vitality. In this guide, we’ll cover the foods crickets consume, practical feeding tips, and answers to common questions.
What Do Crickets Eat in the Wild?
Crickets are omnivorous insects, meaning they eat both plant and animal matter. In the wild, their diet can vary depending on their environment, season, and availability of food. Common wild foods include:
- Plants and leaves: Grass, weeds, and leaves are staples for wild crickets.
- Fruits and vegetables: Fallen fruits like apples, berries, or tomatoes.
- Fungi: Crickets sometimes feed on mushrooms or decomposing organic matter.
- Small insects or larvae: Some species will scavenge or eat smaller insects when available.
Tip: Wild crickets are opportunistic eaters, so they adjust their diet based on what’s accessible.
What Do Pet Crickets Eat?
If you are keeping crickets as pets or feeder insects, providing a balanced diet is essential. Crickets thrive on:
1. Vegetables and Fruits
Fresh produce is a crucial part of their diet:
- Carrots, lettuce, cucumber, and sweet potatoes
- Apples, bananas, and grapes (in moderation to prevent mold)
- Spinach and kale for added nutrients
Visual cue: Look for clean, uneaten produce to ensure crickets are consuming it without spoilage.
2. Commercial Cricket Food
Pet stores sell cricket-specific food, often called “cricket chow” or “insectivore feed.” These are nutritionally balanced, easy to use, and prevent nutrient deficiencies.
3. Protein Sources
Crickets require protein to grow and molt properly:
- Boiled eggs (small amounts)
- Fish flakes or crushed dry dog food
- Occasional small insects
4. Hydration
Crickets need moisture but cannot drink water directly from a dish—they may drown. Safe hydration options:
- Moistened vegetables or fruits
- Gel water supplements made for insects
Tip: Always remove uneaten food after 24 hours to prevent mold and harmful bacteria growth.
Signs of a Healthy Diet in Crickets
You can tell your crickets are eating well by observing:
- Active movement and hopping around
- Shiny, intact exoskeleton
- Regular molting (shedding of their old exoskeleton)
- Increased breeding activity
Symptoms of poor nutrition:
- Weak or lethargic crickets
- Pale or discolored bodies
- Slow growth or unsuccessful molts
- Cannibalism (often due to protein deficiency)
Where Crickets Can Be Found or Live
Crickets inhabit a variety of environments, both in the wild and in captivity:
Wild Habitats:
- Grassy fields, gardens, and forests
- Under rocks, logs, or leaf litter
- Near decaying plants or compost piles
Domestic/Indoor Habitats:
- In homes, crickets may appear in basements or kitchens
- Pet enclosures with substrate, hiding spots, and food/water sources
Note: Crickets are nocturnal, so they are most active during the evening and night.
Practical Tips for Feeding Crickets
- Provide a balanced mix of fresh vegetables, protein, and commercial feed.
- Avoid moldy or rotting food—this can be deadly for crickets.
- Maintain proper humidity (50-60%) to prevent dehydration.
- Use shallow water sources or gel water to hydrate safely.
- Clean their enclosure regularly to prevent bacterial or fungal growth.
FAQs
1. How often should I feed crickets?
Feed crickets daily with fresh vegetables, fruits, or commercial cricket food. Remove leftovers within 24 hours.
2. Can crickets eat only fruits?
No, fruits alone are too sugary and lack protein. A balanced diet with vegetables, protein, and hydration is essential.
3. Why do crickets eat each other?
Cannibalism can occur due to stress, overcrowding, or insufficient protein. Ensure enough food and space to reduce this behavior.
4. Can crickets survive without water?
They need moisture to survive. Provide it through vegetables, fruits, or gel water, as they can’t safely drink from open water dishes.
