The Ultimate Guide to Gut Loading Feeder Insects
The Ultimate Guide to Gut Loading Feeder Insects
Gut loading is the practice of feeding highly nutritious foods to your feeder insects for 24-48 hours before offering them to your reptile. Your reptile is only as healthy as what its food ate. A roach or cricket that has been eating nutritious greens transfers those nutrients directly to your animal at feeding time. An empty feeder is a wasted feeding opportunity.
Which Feeders Can Be Gut Loaded?
| Feeder | Gut Loadable? | Notes |
|---|---|---|
| Discoid Roaches | Excellent | Large gut, hold nutrients 24-48 hours. The best gut-load candidate. |
| Crickets | Moderate | Smaller gut, faster transit. Less effective than roaches. |
| Silkworms | No (mulberry only) | Eat only mulberry chow. Cannot gut-load with produce. |
| BSFL | No (don't need it) | Already calcium-loaded naturally. No gut-loading needed. |
| Hornworms | No (special diet only) | Eat only their prepared artificial diet. |
| Superworms | Moderate | Will eat produce but smaller gut capacity than roaches. |
| Mealworms | Poor | Small gut, fast transit. Least effective gut-load candidate. |
Best Gut-Load Foods
Tier 1: Dark Leafy Greens (Calcium)
- Collard greens — #1 gut-load food. High calcium.
- Mustard greens — excellent calcium
- Turnip greens — strong Ca:P ratio
- Dandelion greens — outstanding all-around (pesticide-free only)
Tier 2: Orange Vegetables (Vitamin A)
- Butternut squash — very high beta-carotene
- Sweet potato — vitamin A rich
- Carrots — classic gut-load food
Tier 3: Fruits (Vitamins, Palatability)
- Mango, papaya, apple, blueberries — use in moderation (higher sugar)
Foods to AVOID
- Citrus — acidity irritates reptile digestion
- Avocado — toxic to many reptiles
- Spinach in excess — oxalates bind calcium (defeats the purpose)
- Iceberg lettuce — zero nutritional value
Timing
Feed gut-load foods 24-48 hours before offering feeders to your reptile. The roach's gut is fullest and most nutritious at 24 hours after eating. After 48 hours, they begin excreting the nutrients.
At All Angles Creatures
Every discoid roach we ship is gut-loaded with organic produce and calcium-rich greens for at least 24 hours before packing. When your order arrives, the roaches are already loaded. For maximum nutrition, continue gut-loading at home if you hold them more than a day before feeding.
