Product-type segmentation distinguishes two supply chains within the Maggot Debridement market. Sterile Lucilia sericata larvae supplied in biodegradable cage dressings dominate because they simplify handling, reduce escape risk, and allow community nurses to perform bedside changesโexpanding addressable volume from inpatient to home-care settings. Conversely, free-range larvae, applied directly to the wound and secured with gauze, remain restricted to specialised clinics; although lower in unit cost, they require consultant oversight and longer bed-days, limiting scalability. The choice between formats is therefore a trade-off between labour cost and procedure standardisation, influencing procurement budgets more than the headline price per larva. Within each format, further sub-variantsโantibiotic-excluded strains, hypoallergenic nettings, and cryopreserved eggsโfine-tune revenue per case without altering the core segmentation logic.
