Medium Crickets | 1/2″

Medium Crickets for Sale

Medium crickets are the 1/2″ size, the everyday staple between small and large. They are usually the house cricket, Acheta domesticus. This size suits mid-sized adults like geckos, chameleons, large frogs, and box turtles. They are lean, high in protein, and arrive gut-loaded. For many established insectivores, this is the main feeder size.

A Staple for Mid-Sized Adults

At 1/2″, medium crickets fit a wide range of common pets at adult size. Their active movement draws a strong feeding response, which keeps animals interested. So they serve as a dependable daily feeder rather than a niche size.

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 animals.

Keeping Medium 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 crickets jump and escape. At this size they hold up well for several days.

Choosing a Size

Medium crickets sit between the small 1/4″ and large 1″ sizes. So match the cricket to the width of your animal’s mouth, and move up as it grows.
