Repashy is proud to announce the anticipated release of our new Hornworm Gutload Diet “SuperHorn”

When Repashy decided to expand its popular insect gel diet line by adding a Hornworm formula,  the first thing we did was look at what was on the market and how to make it better. The first thing we noticed was that there wasn’t a legally labeled product on the market that even listed the basic ingredients, nor a Guaranteed Analysis. We also realize that many of the published and popular recipes include the use of antibiotics and formaldehyde as antimicrobials and preservatives, which may be great for research, but is completely unacceptable in our opinion, for insects used as feeders.  Like all Repashy formulas, SuperHorn is manufactured in our own FDA Registered, FSMA compliant, food manufacturing facility using strict manufacturing practices and full raw material and finished goods traceability.

We conducted research on Hornworm culture by reviewing scores of scientific publications, and lab analyzing commercial diets. We then raised cultures in side-by-side comparisons using published recipes, commercially available formulas, and different beta versions of our own formula over the course of two years.

One thing that stood out to us was that the available diets, while sufficient for efficiently growing worms, they did nothing to focus on improving the nutritional value of them for use as feeders.  At Repashy, we focused on trying to improve the poor calcium levels typical to hornworms by developing a high calcium formula that did not affect growth or survival. We also fortified it with vitamins, carotenoids, trace minerals, and isolated proteins, in order to further maximize nutritional value.

Repashy has used it’s years of experience with plant-based gelling agents, to make a formula that is easy to mix, requires less heat to gel, and has better stability than other products.

We developed this formula to work equally well in the humid conditions of a premade culture cup and the open air conditions of an open top tub used to raise purchased eggs or young larvae, both without spoiling, molding, or desiccating. Hornworms have always been a good feeder option but have not, and are still not recommended to be used as an exclusive diet because of their high fat content. Using Repashy SuperHorn will guarantee that you are getting the most out of your Hornworm feeders by improving nutritional value, survival, and ease of use.
