The amount of mealworms to feed a reptile depends on the species, size, and age of the animal. Generally, up to their head size is what we recommedn for geckos.

Mealworms should be kept in a plastic container with a substrate like oats or bran to provide them with a food source and a place to burrow. The container should be kept at room temperature (around 70-80°F) and away from direct sunlight and moisture. Mealworms can also be refrigerated to prolong their lifespan.

In general, mealworms are safe to feed to reptiles. However, overfeeding or feeding mealworms that are too large can cause digestive issues, such as impaction. It's also important to purchase mealworms from a reputable source to ensure they are free of any harmful substances or pesticides.

The process of gut-loading mealworms involves feeding them with a nutrient-rich diet before giving them to your reptile as food. You can accomplish this by providing mealworms with fruits, vegetables, and commercial gut-loading products for a duration of 24-48 hours before offering them to your reptile.
