PROBLEM TO BE SOLVED: To provide a housefly larva rearing method and a rearing facility for isolating housefly larvae themselves and making the housefly larvae harmless and utilizing them in parallel with fertilization of organic waste such as livestock. SOLUTION: This is a breeding method for collecting housefly larvae bred with organic waste, and the breeding equipment 1 comprises an open box body 10 on which an organic waste 9 is placed and a ceiling surface is open, and an open box body. The larva carrying section 20 disposed below the section 10 and the larval insect killing section 40 connected to the larva carrying section 20 for killing the housefly larva M are provided, and hatched from housefly eggs administered to the open box section 10. Larvae breeding step of breeding in the open box part 10 the housefly larva M or the pre-hatched young housefly larva M administered to the open box part 10, and growing inside the open box part 10 and outside the open box part A collecting step of collecting the housefly larva M that has crawled out of the open box body 10 by the larva transporting section 20 and an insecticidal step of killing the housefly larva M in the larva killing section 40.
