A method for domesticating wild flies is a method aiming at preferably improving fly population under wild conditions. The method mainly comprises maggot obtaining, sterilizing, maggot hatching and fly domesticating. The steps are as follows: the maggots are fished from the cesspits by fishing tools and then are placed into the prepared feed after being cleaned, the maggots grow and mature 2-3 days later, then the mature maggots are collected into a big plastic pot, and bran is scattered on the maggots and a woven bag is covered on the maggots to prevent the maggots from escaping; 2-3 days later, the maggots become red pupae and the pupae are sifted out with sieves, sterilized with potassium permanganate solution for 10min and then fished out and aired; the pupae are placed into the plastic pot again and little bran is scattered to continue hatching; the first batch of hatched flies need to be fed with the best feed under quiet environment to increase the spawning rate, when the descendants of the first batch of flies begin hatching, the seed maggots are timely evicted out of the culture room, and after the above processes are repeated until the fourth generation, the domestication of the seed maggots succeeds.
