Maggots, often viewed negatively for their role in decomposing carcasses, are finding a surprising application in modern medicine. Known as maggot therapy, these tiny creatures are being used as a form of wound cleaning. Polly Cleveland from New York City turned to maggot therapy while caring for her husband, Tom Haines, in 2023. After his hospital stay, he developed painful sores, prompting Cleveland to explore unconventional treatments.
Doctors and nurses managing Tom’s care were unaware of this therapy. Driven by her interest in insects, Cleveland reached out to Dr. Ronald Sherman, a pioneer in maggot therapy. She acquired maggots from his lab for their treatment. Medicinal maggots are considered FDA-cleared medical devices. They are specifically cultured to ensure they remain sterile and are used to target infected tissue.

This approach offers a non-surgical option for wound debridement. Surgical methods can be less precise, often removing both healthy and dead tissue. Maggots, however, are capable of eliminating dead tissue with precise efficacy. This is because they work on a microscopic level, unlike surgical instruments, which operate macroscopically.
Maggot therapy is beneficial for patients unable to undergo surgery. It requires no anesthesia, making it safer for those at higher surgical risk. Lisa Baxter from Tufts Medical Center mentions its use for patients needing rapid healing before organ transplants. Maggots notably avoid Pseudomonas bacteria, requiring careful wound assessment before use.
Dr. David Armstrong from the University of Southern California employed maggots for his patient during the pandemic. With surgery canceled, maggot therapy became a viable home treatment, preventing further deterioration of the patient’s condition.
Challenges and Perception
Despite its advantages, maggot therapy faces several obstacles. Insurance coverage for this treatment is often inadequate, as noted by Dr. Sherman. Maggots are less expensive than enzymatic debriders but lack extensive insurance support.
Dr. Sameer Patel highlights the scarcity of substantial data supporting widespread use. While maggot therapy has proven effective in specific cases, he believes it is unlikely to become mainstream. Additionally, the aversion rooted in the ‘yuck factor’ remains a barrier. Patients may receive prescriptions for maggots, but implementation is hindered by reluctance from healthcare providers.
Larry Way, treated at Tufts Medical Center, overcame initial reservations about maggot therapy. Despite a dire prognosis, the therapy exceeded expectations by improving his condition.
Ultimately, maggot therapy may not be universally embraced, but in cases where standard treatments fall short, its potential cannot be ignored.
