GLH began as a reptile breeding facility in 1997. We started using hornworms in the middle of 2004 to increase the variety of feeders we were offering our animals. It didn't take long before we noticed the added benefits of feeding hornworms. Our animals were able to sustain and even gain weight during the breeding season, recovered faster after laying eggs, and were not taxed as hard from the breeding season. After experimenting with different rearing conditions and diet formulations, Great Lakes Hornworm was able to produce hornworms on a consistent basis. Since the beginning, we have added different insect species and supplies to meet our customer’s needs. Whether you need reptile food, fishing bait or research insects we are here to meet your needs.
