Insect larvae are ferocious eaters and thus can eat a large variety of feed substrates.
Generally used feed substrates include by-products and surplus production from the bakery, potato, vegetable, fruit processing industry as well as pre-consumer wastes from retail and grain by-products.
When Hive PRO is deployed in the European Union, there are legal requirements on the type of feed input. Insects may only be fed with materials of vegetal origin. Some exceptions are however admitted for materials of animal origin such as milk, eggs and their products, honey, rendered fat or blood products from non-ruminant animals. The feeding of farmed animals with other slaughterhouse or rendering derived products, manure, or catering waste is however prohibited. The same ban applies to the use of unsold products from supermarkets or food industries (e.g. unsold products in reason of manufacturing or packaging defects) if these contain meat or fish.
