Vet Guide 2025: Raising & Breeding Crickets for Reptile Diets by Dr Duncan Houston 🦗🩺

Hello! I’m Dr Duncan Houston, BVSc and the founder of Ask A Vet. Crickets are a staple live prey for many insectivorous reptiles—but providing nutritious, clean, gut‑loaded food means raising and breeding them responsibly. This 2025 guide covers habitat setup, breeding lifecycle, dietary preparation, hygiene, and storage so your reptile receives optimal nutrition. 🌿

1. Why Raising Your Own Crickets Matters

Commercial feeder insects often lack nutrients, may be carrier of parasites, or arrive weak. Raising your own crickets ensures they are healthy, well-fed, and appropriately sized for your reptile—supporting better growth and immunity.

2. Setting Up the Cricket Habitat

• Container: A 10–20 gal plastic tote with secure, ventilated lid works well (mesh or drilled holes).
• Bedding: Use egg cartons or cardboard to increase surface area and reduce cannibalism.
• Temperature: Maintain 80–90 °F; this supports breeding and activity.
• Humidity: Keep 50–60% to prevent dehydration, but avoid mold—spray lightly.
• Heating: Use an under-tank heat mat or small heat lamp controlled by a thermostat.

3. Feeding & Gut-loading Crickets

• Provide fresh, insect-grade feed—cricket chow or dog food crumbs.
• Offer fresh vegetables and fruits: carrots, sweet potato, greens; replace daily.
• Calcium & vitamin dust: sprinkle lightly on feeder to boost nutrient value.
• Supplement with water source—moistened paper towel or sponge; avoid drowning hazards.

4. Breeding Cricket Lifecycle

1. Egg laying: Provide moist substrate (peat moss, vermiculite) in a covered box.
2. Incubation: Maintain 85–90 °F; eggs hatch in ~10–14 days.
3. Nymph stage: Transplant tiny nymphs into small container, feed finely ground food.
4. Adulthood: Crickets mature in 4–6 weeks—segregate by size to prevent cannibalism.

5. Cleaning & Maintenance

• Spot clean daily—remove dead crickets and mold.
• Replace bedding every 1–2 weeks.
• Deep clean and disinfect habitat monthly; allow it to dry fully before reusing.

6. Feeding to Your Reptile—Best Practices

• Use tongs to offer appropriately-sized crickets—no bigger than the width of the reptile’s head.
• Pre-gut-load for 24 hours on veggies/supplement mix before feeding to your reptile.
• Remove uneaten crickets within an hour to prevent tank contamination.

7. Emergency Cricket Storage & Care

• If left over past feeding time, store in a ventilated cool area (65–75 °F).
• Feed lightly and monitor humidity to keep them alive for several more days.
• Past 2–3 days, consider euthanizing expired feeders humanely (freeze method preference).

8. Nutritional Value & Supplementation

A properly gut‑loaded cricket offers:

• Protein ~ 60–70%
• Fat ~ 15–20%
• Calcium ~ 0.5–1% (post-dusted)
• Vitamins from fresh produce

Supplement with calcium + D₃ 2–3× weekly, and multivitamins weekly to prevent MBD in reptiles.

9. Health & Hygiene Risks

• Risk of mites—inspect crickets regularly and clean habitat if any infestations appear.
• Mold and bacteria grow rapidly in humid habitats—maintain clean bedding and dry conditions.
• Quality of water is essential—even slight contamination can kill young crickets.

10. When to Seek Veterinary Advice

• Your reptile refuses feeder insects despite normal appetite—possible health issue.
• Respiratory signs or regurgitation after feeding—check prey size or contamination risk.
• Observe unusual regurgitation or weight loss—evaluate hygiene, prey quality, and feeding schedule.
• Ask A Vet can review feeding logs, reptile behavior, and offer targeted guidance 🐾.
