Our Springtail culture is a greatway to begin breeding Springtails for Terrariums, Vivariums, or for other reptile & amphibian setups! We ship with a soil that can hold moisture extremely well. When they arrive, we recommend immediately feeding them with DBDPet's Springtail Food. If you want to use them, you can just dump the entire culture right into your vivarium, and mix the substrate we send into your terrarium's substrate. We offer a Worry Free Live Arrival Guarantee. If your culture arrives dead, simply take photos, and send them to us. We will take care of you, but be aware, because Amazon is handling these for us, they may gas themselves out. Do not throw out a "bad" culture as the eggs can hatch and you could unknowingly be throwing away 100s of baby Springtails.
