Each hornworm pod contains 15-20+ hornworms and enough food to grow them to full size at over 3" long. These are just like our silkworm pods only with hornworms. These are large green worms that your animals can not resist, great for picky eaters and animals on hunger strikes. The pod is self sufficient, all you have to do is dump out the waste that will build up as the worms eat and grow. We ship small size worms due to the rapid growth rate of the hornworm by default.
