Housing dubia is similar to how you house crickets. They will need a plastic tub with a ventilated lid, egg flats to climb and hide in, a source of food, and a source of water and kept at room temp or slightly warmer (unless you are trying to breed them, you don't need to worry about a heating pad or other heating source). When providing them with a water source, you will need to consider that they can drown in plain water, this is why water crystals are the best thing you can get for them as they will be able to hydrate with no risk of drowning. When it comes to food, the best thing to use is dubia diet for the bulk of their meals, you can also use vegetables that are safe for your reptile such as carrots, sweet potato, butternut, spaghetti or acorn squash, and more!
