The first step in feeding your reptile crickets will be to gather the crickets. You can buy crickets on-line or from a local pet store, raise them yourself, or capture them from outdoors. Whichever way you choose, make sure you have enough crickets to feed your particular reptile enough and maintain a good level of nutrition. You will want to buy house crickets (Acheta domestica) for your reptile. Don't buy too many crickets at once as they may die before your reptile gets a chance to eat them all. You will likely want to have some kind of storage container for your crickets. A plastic bin with cardboard tubes for the crickets to hide in can work fine. An important part of offering crickets to your reptile is selecting crickets that are a safe size. Exactly how large the crickets you choose are will depend on how large your reptile is. Larger reptiles will enjoy larger crickets. However, smaller reptiles may be injured by larger crickets or may not eat them at all. Make sure the crickets you are offering are an appropriate size for your reptile. Your reptile should be able to easily fit a cricket in their mouth. Crickets larger than your reptiles mouth should likely be avoid. If a cricket is larger than the distance between the reptile's eyes, it's too big. In order to provide the best nutrition for your reptile, you will want to dust the crickets in a coating of calcium powder. This will allow your reptile to get even more nutrition and ensure that they are strong and healthy, reducing the chances of illness or injury occurring. Always make sure to coat the crickets in calcium powder when feeding your reptile. This powder can be bought at most pet stores or online. You can put the powder in a simple plastic container. A tall plastic pitcher can work well. Shake some crickets into the container. Lightly shake the container to coat the crickets in the powder. The crickets should be coated completely in the calcium powder and can then be fed to your reptile. It's a good idea to find a powder that contains both calcium and vitamin D3. Once you've dusted the crickets and selected which ones are an appropriate size for your reptile, you can begin introducing them to your reptile's enclosure. If you already know how much your reptile generally eats, add only that amount of crickets to the cage. If you are unsure of how many to add, try adding only a few at a time and waiting to see if your reptile eats them all, before adding more. Don't dump an uncounted amount of crickets into the reptile's enclosure. You can try adding them one at a time by picking them up with tweezers and placing them in the enclosure.
