Koi Treats

Natures Grub is a family run business that was established in 2009 and has grown from our own passion for keeping koi carp.

Frustrated with the quality and price of the products available at the time, we did our research, found out who grew the products and after many hours of searching, piles of paper work and forms to fill in we managed to import 4 boxes each of silkworm pupae, river shrimp and mealworms for our own use and sold the rest on the internet and hey presto Natures Grub was born.

From our start in an old brick building attached to our house we have moved several times over the last few years and Natures Grub is now to be found in the Norfolk Town of Fakenham on the outskirts of the town centre, our product range has grown. We now have probably the largest range of dried insects and crustaceans in the country (over 30 varieties), imported by the container load from suppliers all over the world.
