How to Gut-Load Insects for Green Tree Frogs

Gut-loading is the process of feeding your feeder insects (such as crickets, roaches, mealworms, etc.) a highly nutritious diet 24–72 hours before offering them to your green tree frogs. This boosts the nutritional value of the insects, ensuring your frogs receive essential vitamins and minerals, especially calcium and vitamin A, which are often lacking in standard feeder insects.

Step-by-Step Guide to Gut-Loading Insects

1. Choose a Nutritious Gut-Loading Diet

  • Use a commercial gut-loading formula designed for feeder insects, or
  • Prepare your own mix using:
    • Dark leafy greens (kale, collard greens, dandelion greens)
    • Carrots, sweet potato, squash
    • Other vegetables and fruits (apple, pear, zucchini, cucumber)
    • High-quality dry foods (such as fish flakes, chicken feed, or commercial cricket diets)

2. Provide Moisture

  • Offer moisture-rich foods like carrot, apple slices, or sweet potato instead of a water bowl (insects can drown in standing water).
  • Alternatively, use commercial insect hydration gels.

3. Feed the Insects

  • Place your feeder insects in a clean container with the gut-loading diet and moisture source.
  • Provide enough food for the insects to eat continuously for 24–72 hours before feeding them to your frogs.

4. Keep the Environment Clean

  • Change out uneaten fresh food daily to prevent mold and bacteria.
  • Remove decaying food promptly.

5. Dust with Supplements Before Feeding

  • Right before offering the insects to your frogs, dust them with a calcium supplement (with vitamin D3) and, 2–3 times per week, a multivitamin powder.

Tips and Best Practices

  • Timing: Gut-load insects for at least 24 hours, ideally up to 48–72 hours, before feeding.
  • Variety: Rotate gut-loading ingredients to provide a broad spectrum of nutrients.
  • Avoid: Do not use citrus, onion, or capsicum (bell pepper), as these can be harmful to insects and, by extension, your frogs.
  • Monitor: Ensure insects have constant access to food and moisture during gut-loading.

Example Gut-Loading Recipe

  • Chopped kale or collard greens
  • Shredded carrot or sweet potato
  • Slices of apple or pear
  • High-quality commercial cricket or roach diet
  • Occasional addition of fish flakes or chicken feed for protein

In summary:
To gut-load insects for your green tree frogs, feed the insects a nutrient-rich diet of vegetables, greens, and quality dry foods for 24–72 hours before offering them to your frogs. Always provide a moisture source, keep the insect enclosure clean, and dust the insects with calcium and vitamins just before feeding. This ensures your frogs receive the best possible nutrition from their prey.

How to Feed Green Tree Frogs

Feeding green tree frogs properly is essential for their health and longevity. Here’s a comprehensive guide based on expert recommendations:

What to Feed

  • Diet: Green tree frogs are insectivores. Their diet should consist mainly of live insects such as:
    • Crickets (brown or black)
    • Cockroaches (woodies)
    • Earthworms
    • Silkworms
    • Mealworms (in moderation)
    • Waxworms (as treats, due to high fat)
    • Calci-worms
    • Black soldier fly larvae
    • Occasional moths or small locusts.

Note: Avoid feeding wild-caught insects, as they may carry parasites or pesticides.

How Much and How Often

  • Juveniles: Feed daily, offering as much as they will eat in about 15 minutes.
  • Adults: Feed every 2–3 days (2–3 times per week), providing 10–20% of their body weight per week or 2–3 appropriately sized insects every 2 days.
  • Best Time: Feed in the evening or at night, as green tree frogs are nocturnal and most active then.

Feeding Techniques

  • Free-Range Feeding: Release live insects into the enclosure and allow the frog to hunt.
  • Tong/Hand Feeding: Use feeding tongs or forceps to offer insects directly, ensuring each frog gets its share, especially in group settings.
  • Feeder Rocks/Logs: Use enrichment tools where insects are placed inside and released gradually, encouraging natural hunting behaviours.

Supplementation

  • Calcium and Vitamins:
    • Dust insects with a calcium supplement (with vitamin D3) at every feeding for juveniles and every other feeding for adults.
    • Use a multivitamin supplement 2–3 times per week for adults and daily for juveniles.
  • Gut-Loading: Feed insects a nutrient-rich diet (gut-load) 24–72 hours before offering them to your frog to boost their nutritional value.

Portion Size

  • Only offer prey items that are no larger than the space between the frog’s eyes to prevent choking or impaction.
  • Remove uneaten insects after feeding to prevent them from harming or stressing the frog and to keep the enclosure clean.

Water

  • Always provide a shallow dish of clean, dechlorinated water for soaking and drinking. Change the water daily.

Summary Table: Feeding Green Tree Frogs

Age/StageFrequencyAmount/TypeSupplements
JuvenileDailyAs much as eaten in 15 min, small live insectsCalcium + D3 daily, multivitamin daily
AdultEvery 2–3 days2–3 insects per feeding, variety of live insectsCalcium + D3 each feeding, multivitamin 2–3x/week

In summary:
Feed green tree frogs a varied diet of appropriately sized, gut-loaded live insects, dusted with calcium and vitamins. Juveniles eat daily; adults every 2–3 days, preferably at night. Always provide clean, dechlorinated water and remove uneaten food to maintain a healthy environment.
