Extra Small Silkworms for Sale
Extra small silkworms run about 1/8″ to 1/4″, the smallest size we offer. They are the larvae of the silk moth Bombyx mori, and they suit small reptiles and babies. Silkworms are soft-bodied and easy to digest, high in protein, and low in fat, so they make a strong staple or a nutritious treat. TC grows them in a Houston silkworm lab with clean breeding, free of toxic chemicals, parasites, and disease.
A Soft, Nutritious Feeder
Silkworms have no hard shell, so they digest easily and carry a low impaction risk. That suits picky eaters, young animals, and pets recovering or needing to rehydrate. They are high in protein and low in fat, and many reptiles take them even when refusing other feeders. So they earn a regular place in the diet.
Sized for Small Reptiles
This extra small size fits dart frogs, baby chameleons, baby bearded dragons, and other small reptiles. Because silkworms are counted by hand, sizes are approximate. As your animal grows, step up to the small and medium sizes.
Calcium and Variety
Silkworms have a better calcium balance than crickets or mealworms, one of the few feeders that come close to a healthy ratio. So many keepers feed them without dusting. Even so, vary the diet and lightly supplement for fast-growing or breeding animals, and feed silkworms as part of a rotation since they are high in moisture.
Care
Keep silkworms at room temperature, not in the refrigerator, since cold harms them. This differs from mealworms. Keep them with their chow, since they ship with only 2 to 3 days of food. Buy more chow to grow them out or hold them, and larger worms eat faster. Cared for well, a batch lasts about a month.
