🐛 Understanding the Worm Trio: Mealworms, Giant Mealworms, and Superworms

Feeder insects are the backbone of many reptile diets, and choosing the right worm can make a big difference in your pet’s health and feeding behavior. At Cucaracha Plug, we’re passionate about helping keepers make informed, ethical choices—so here’s a breakdown of three popular options: mealworms, giant mealworms, and superworms.

Mealworms are small, slow-moving larvae with a hard exoskeleton.
Giant mealworms are chemically treated mealworms that grow larger .
Superworms are unrelated to mealworms and are larger, more active, and better suited for stimulating reptile hunting behavior

🦎 Who Eats What?

Mealworms are ideal for:

  • Leopard geckos

  • Juvenile bearded dragons

  • Small amphibians

  • Insectivorous birds

Giant Mealworms are suitable for:

  • Medium-sized reptiles needing a larger bite

  • Occasional feeding

Superworms are great for:

  • Bearded dragons

  • Skinks

  • Monitors

  • Larger geckos (e.g., tokays)

⚠️ Note: Mealworms and giant mealworms have high chitin content, which can be hard to digest. Superworms are softer and more hydrating.

🏡 How to Care for Each

Mealworms & Giant Mealworms:

  • Keep in bran, oats, or chick mash

  • Provide fresh veggies and protein-rich foods

  • Separate larvae to trigger pupation

🐞 Breeding Tips

Mealworms:

  • Allow pupation at room temp

  • Adults are darkling beetles

  • Eggs hatch in 1–2 weeks

  • Easy to breed in bulk

Superworms:
