Fly farming is a distinctive project for producing high-protein fly larvae feed

Fly farming is an artificial insect farming project that targets flies such as the housefly, with the main purpose of harvesting fly larvae. Fly larvae have a relatively high protein content and a fairly complete amino acid profile, and are commonly used as animal protein feed for aquaculture, poultry and specialty farming; they can also be used to convert organic waste such as livestock and poultry manure and kitchen scraps.

Flies have strong reproductive capacity, short generations and a varied diet, and grow rapidly under suitable temperature and humidity conditions, so the farming cycle is relatively short. The housefly is the most common species farmed, and some farmers also choose other fly species according to their purpose. The investment in facilities for the project is relatively small, and it is easy to integrate with livestock and poultry farms and aquaculture farms to form a resource-recycling model.

Farming is generally carried out in enclosed insect rooms or net houses, with the key focus on temperature control, humidity control and ventilation. During the adult stage, an egg-laying substrate is used to encourage concentrated egg laying; during the larval stage, culture media such as bran and manure are spread out for rearing, and once they reach the required size the larvae are separated and harvested promptly. Daily management must strictly prevent adult flies from escaping, also guard against rats and birds, and keep the site clean and hygienic.

In terms of application, fly larvae can be fed directly as live larvae, or dried to make dried larvae or insect meal to replace part of the fishmeal used, and the leftover insect frass from farming can also be returned to the fields as organic fertilizer. It should be noted that before starting farming you should understand the relevant local regulations, choose a reasonable site to avoid odor nuisance, and disinfect the breeding stock; imbalanced temperature and humidity and moldy substrate are common problems for beginners, and should be adjusted promptly during daily inspections.
