You probably don't need to worry about maggots making a home in your vagina, but this very rare condition, known as myiasis of the vagina, does affect a handful of people. 

Fly larvae cause this parasitic infection, which can lead to itching, wounds, and the death of vaginal tissue. 

Two major factors increase your odds of developing this infection: open wounds in the vaginal area and physical location. 

Vaginal myiasis most commonly affects people living in tropical and subtropical climates, and most cases develop in the summer. 

People who lack secure housing and adequate bathing facilities, or live in poor sanitary conditions, are also more likely to experience vaginal myiasis, says Kimberly Langdon, obstetrician and gynecologist at Medzino

Only a few individual case studies have reported on this condition in the human vagina, but experts do know it's not sexually transmitted — despite a number of internet rumors suggesting otherwise

Here are the facts about this rare condition. 

How it happens

Myiasis happens when certain fly species lay their eggs near wounds or other moist openings in another animal's body. 

Female flies lay up to 300 eggs at a time in a warm, high-nutrient environment — in this case, the human vagina. Once the eggs hatch, the larvae feed on the host's body, causing a range of infestations. 

"It takes around 12-24 hours for maggots to infiltrate the body, but the larvae can take four days to hatch completely," says Aaron Gelfand, obstetrician and gynecologist at ChoicePoint.

Those maggots become adult flies in a week and lay their own eggs in a similar environment, continuing the cycle.

Myiasis doesn't affect the human body very often — it's more common among cows, sheep, and other farm animals

However, vaginal myiasis cases in humans can affect your:

As noted above, one of the biggest risk factors for vaginal myiasis is open wounds or sores in the genital area. Other medical conditions associated with chronic wounds, like diabetes and peripheral vascular disease, can also increase your risk.  

Important: Since certain sexually transmitted infections (STIs) may cause open sores, it's important to seek treatment for STI symptoms right away. 

Signs and symptoms

First, you might notice a new protruding bump in your vaginal or vulval area that resembles a bug bite

Over a few days the bump will grow and develop a pinpoint at the center, which allows maggots to breathe when they hatch. 

You might also notice some movement in your skin on and around the bump — this suggests live maggots in the area.

While the rarity of this condition means that research remains limited, case studies cite the following symptoms:

The maggots, or larvae, that cause myiasis in humans are typically born from blowflies or houseflies

These larvae may resemble worms, and they can grow up to an inch long. You may notice they appear pale white, off white, or yellow. 

Maggots may appear translucent or transparent, with no eyes and a wide mouth. 

Treatment

A medical practitioner will typically start treatment by surgically removing any larvae and dead tissue. After that, they'll clean the infected area to ensure all of the maggots are gone for good.

Depending on the severity of your symptoms, you may have to stay in the hospital for a couple of days while you receive antibiotics intravenously to prevent any secondary infections. If you have milder symptoms, the physician may send you home with a prescription for antibiotics and ivermectin.

Myiasis isn't deadly, but without treatment, it can lead to more tissue death and open wounds in the genital area. These wounds and sores can increase your risk of STIs and affect your overall health.

Without medical intervention, maggots may also keep growing in your body.

Insider's takeaway

Myiasis in humans, especially in the genital area, is extremely rare. If you think you have vaginal myiasis, your doctor can help diagnose and treat this condition, typically with surgery and antibiotics.

While research remains in the early stages, treatment and prevention are relatively straightforward. Cleansing open wounds and treating health concerns, like STIs, that might contribute to myiasis will significantly reduce your chances of developing this already uncommon condition.
