If you do not have antibiotics and the wound has become severely infected, does not heal, and ordinary debridement is impossible, consider maggot therapy, despite its hazards:

Expose the wound to flies for one day and then cover it.

Check daily for maggots.

Once maggots develop, keep wound covered but check daily.

Remove all maggots when they have cleaned out all dead tissue and before they start on healthy tissue. Increased pain and bright red blood in the wound indicate that the maggots have reached healthy tissue.

Flush the wound repeatedly with sterile water or fresh urine to remove the maggots.

Check the wound every four hours for several days to ensure all maggots have been removed.

Bandage the wound and treat it as any other wound. It should heal normally.
