As the University of Maryland responds to a reported body lice outbreak on campus, here’s what to know about dealing with the pests.

The University Health Center wrote in a news release Thursday that the university’s Pest Control Management Units have “inspected and thoroughly treated” the areas on campus where body lice were reported. Additional inspections are continuing to make sure other areas do not have lice, the release read.

What are body lice?

Body lice are insects that feed on human blood, according to the U.S. Centers for Disease Control and Prevention. The bugs spread through direct contact with another person who is infected with body lice.

The parasites can be about the size of a sesame seed. Lice will often bite you on the parts of your body that come into contact with clothing seams, including your armpits, groin, neck, shoulders and waist, according to the Mayo Clinic.

Body lice tend to crawl into the seams of clothing and lay eggs there, the CDC’s website read. If you have body lice, you might see eggs in the seams of your clothing or see a bug crawling or feeding on you, according to the CDC.

If you’re unsure whether you are infected, visit a health care provider or the health center.

What symptoms do body lice lead to?

Similar to head lice, body lice can lead to harsh, frequent itching, bites and an allergic reaction that causes a rash, according to the CDC. Repetitive and vigorous itching can create sores that allow for bacterial infection in the skin.

The university’s health center wrote in a Thursday evening news release to contact the center if you experience body lice symptoms.

How do you prevent and treat body lice infections?

Regular bathing and machine washing your clothes and bedding can help prevent the spread of body lice. The CDC recommends washing clothing, sheets and towels at a temperature of at least 130 degrees Fahrenheit and machine drying them on high heat.

You should also vacuum carpets and furniture. If you can’t wash an item, place it in a sealed bag for two weeks, the health center recommends.

Do not share clothing, bedding, towels or beds with anyone who has lice, the center wrote in Thursday’s news release.
