Large Crickets for Sale
Large crickets are the 1″ size, the biggest feeder cricket. They are usually the house cricket, Acheta domesticus. This size suits larger animals like adult bearded dragons, large lizards, and chameleons. They are lean, high in protein, and arrive gut-loaded. For big, established insectivores, this is the main feeder size.
Match the Cricket to the Animal
Because these are the largest crickets, feed them only to animals big enough to handle them. A good rule is to keep prey no wider than the space between your animal’s eyes. Oversized prey can cause choking or impaction. So for smaller animals, choose the medium or small size instead.
Dust With Calcium Before Feeding
Like all crickets, these are low in usable calcium and carry more phosphorus. So dust them with a supplement such as TC Calcium Ultra Fine before feeding. Keeping them gut-loaded helps too, which supports steady calcium for your animal.
Keeping Large Crickets
Keep them warm and well ventilated, with egg-crate or cardboard for hiding. Provide moisture through a gel or water crystals, or a slice of vegetable, rather than an open dish they can drown in. Keep the container closed, since adult crickets jump and chirp. At this size they hold up well for several days.
