A biological control method for centipede breeding belongs to the field of special economic animal breeding technology. This invention uses a compound probiotic strain of *Trichoderma longicornis*, *Streptomyces flavus*, *Bacillus subtilis*, *Bacillus licheniformis*, *Clostridium butyricum*, and lactic acid bacteria, which is fully incorporated into the breeding substrate. After 24-72 hours of static setting, the bacteria fully colonize and form a stable antibacterial state. The bacterial community can remain dormant during periods of nutrient deficiency, low-temperature overwintering, or year-end static setting, and will revive upon contact with organic matter. The method is supplemented with springtails and pink woodlice, which preferentially consume harmful bacteria, clean up uneaten feed, and primarily feed on and decompose centipede feces, forming a mutually beneficial symbiotic relationship with the biocontrol bacteria. Their feces further nourish the bacterial community, extending the stable effective period of the bacterial community from 2 months to 4-6 months or more. Simultaneously, probiotics and vitamins are added to the feed to strengthen the centipede's constitution. This invention constructs a three-dimensional synergistic prevention and control system that integrates matrix inhibition of pathogenic bacteria, environmental residue removal, and internal administration for enhanced protection. This system enables drug-free ecological disease control, significantly reduces the incidence of diseases such as green muscardine, and improves the survival rate of centipede farming.
