MDT uses "sterile" larvae, Phaenica sericata, which are placed on a person's wound twice a week and left there for 48 to 72 hours. The maggots only eat dead tissue, leaving live tissue intact.
What happens if you leave maggots in a wound?
They secrete an enzyme that breaks down the devitalised tissue in the wound and in effect, the maggots “drink” the liquefied tissue and bacteria. As maggots do not have teeth, they take longer to break down hard, dry necrotic tissue, and if placed in such a wound, they can die of starvation.
How long are maggots left in a wound?
'Free range' maggots are generally left in place for up to three days before being removed from the wound site.
Can maggots live in wounds?
Wound myiasis: occurs as a result of egg deposition on decaying flesh or pus-discharging wounds. If the maggots invade rather than staying on superficial layers of exposed tissue, subcutaneous nodules can result.
How long does it take for maggots to hatch in a wound?
Female flies may visit wounds to feed or to lay eggs. They generally lay 50-300 eggs at a time and at skin temperature these hatch around 8-12 hours later.

Should you remove maggots from a wound?

It may be possible to see or feel the larvae wiggling under the skin during this time. When larvae are fully matured, they burst out of the skin and fall off. As fully formed maggots, they continue to grow into maggot flies over a three-week period.
Why do maggots appear in the human body?
The adult flies are not parasitic, but when they lay their eggs in open wounds and these hatch into their larval stage (also known as maggots or grubs), the larvae feed on live or necrotic tissue, causing myiasis to develop. They may also be ingested or enter through other body apertures.
How do you deal with a maggot infestation?
If you find maggots in food or the trash, you can boil them and the eggs together to kill them. Another option is to thoroughly sprinkle them with salt or spray them with an insecticide. If you find them in carpeting or baseboards in your home, you will generally need to spray.
How do you remove larvae from skin?
Surgical removal with local anesthesia
The skin lesion is locally anesthetized with lidocaine and excised surgically followed by primary wound closure. Alternatively, lidocaine can be injected forcibly into the base of the lesion in an attempt to create enough fluid pressure to extrude the larvae out of the punctum.
How long does it take for maggots to form in the body?
Without the normal defences of a living animal, blowflies and house flies are able to lay eggs around wounds and natural body openings (mouth, nose, eyes, anus, genitalia). These eggs hatch and move into the body, often within 24 hours. The life cycle of a fly from egg to maggot to fly takes from two to three weeks.

How effective is maggot therapy?
The maggot therapy facilitated faster and more effective debridement of non-viable tissue. It enabled faster development of granulation tissue and increased reduction in the wound surface area compared to hydrogel dressings. Maggot therapy had no effect on disinfection or complete healing rate for the wound.
Is Wet gangrene curable?
The prognosis is generally favorable except in people in whom the infection has spread through the bloodstream. Gangrene is usually curable in the early stages with intravenous antibiotic treatment and debridement. Without treatment, gangrene may lead to a fatal infection.
