Yes, pubic lice can live on eyebrows, eyelashes, and other coarse body hair — not just the genitals. These same insects (Pthirus pubis) sometimes spread to the lashes, beard, chest, or armpit hair. Eyelash infestations are special: standard lice insecticides are unsafe near the eye, so they're treated with ophthalmic-grade petrolatum instead CDC.

The essentials: where crabs live beyond the pubic area
Pubic lice are small, blood-feeding insects shaped a bit like tiny crabs — that crab-like grip is what lets them cling to thick, widely spaced hairs. They prefer coarse hair, which is why the pubic and perianal area is home base, but the armpits, chest, beard, and even the eyelashes and eyebrows can all support them CDC. They're a separate species from head lice and body lice, and they don't usually colonize the fine hair of the scalp.
They spread mostly through close sexual contact, since that's when the right kind of hair is pressed together long enough for a louse to walk across. Eyebrow and eyelash infestations in adults often trace back to genital lice carried on the hands or by intimate face-to-face contact. In children, lice on the lashes deserve a careful, non-judgmental look at how the contact happened. For the full picture of transmission, see how you get crabs.
Symptoms: what crabs in eyebrows and eyelashes feel like
Many infestations cause no symptoms at all, especially early on. When symptoms do show up, the hallmark is itching where the lice are feeding — that includes the genital area and, with facial involvement, the brow line or the rim of the eyelids. The itch comes from your body reacting to louse saliva, so it can take time to develop after the lice arrive.
On the lashes and brows you may notice a few specific things:
- Tiny tan or grayish specks clinging to the base of the lashes or brow hairs — these are the lice themselves, which are visible to the naked eye but easier to spot with a magnifying lens.
- Whitish, oval nits (eggs) cemented firmly to the hair shaft, which don't slide off the way dandruff or crusts do.
- Itching, irritation, or a gritty feeling along the eyelid margin.
- Redness or crusting of the eyelid edges, which can look like ordinary blepharitis (inflammation of the eyelid margin) and is sometimes mistaken for it.
- Sores or signs of secondary infection from rubbing and scratching.
Because the genital area is the usual reservoir, check there too — finding lice or nits in the pubic hair often confirms what's going on. For the broader symptom rundown, see our guide to crabs symptoms.
Testing and diagnosis
Diagnosis is visual, not a lab test. A clinician confirms pubic lice by finding a live louse or its nits on the hair — in the pubic region, on the eyelashes, or wherever else they've settled CDC DPDx. For lashes, that often means a slit-lamp or magnified eye exam, which is why an eyelash infestation is one good reason to be seen rather than self-treating blind.
In real life, this is a quick, low-drama visit — clinics handle it routinely, and a diagnosis says nothing about you as a person. Because pubic lice spread through sexual contact, it's reasonable to screen for other infections at the same time; many of those are diagnosed from a simple urine cup, a self-collected swab, or a brief exam, with results usually back in a few days, often free or low-cost at health departments, Planned Parenthood, and Title X clinics. You can get tested for the rest, and if you're timing things after a possible exposure, read up on when to test after exposure.
Treatment: why eyelashes are different
For the genital and other body-hair areas, the standard approach is an over-the-counter lice treatment — a permethrin lotion or a pyrethrins-with-piperonyl-butoxide mousse — applied to the affected hair and washed off as directed, then repeated in about a week and a half if live lice remain CDC STI Tx Guidelines. That's the playbook for the pubic area, armpits, chest, and beard.
The eyelashes are the exception, and this is the part people get wrong. You should not put insecticidal lice lotions or shampoos near the eyes — they can irritate or damage the eye. Instead, eyelash infestations are treated with ophthalmic-grade petrolatum applied to the lid margins, which smothers the lice over several days. Note that this is the sterile, eye-safe petrolatum a clinician or pharmacist provides — not the jar of regular Vaseline from the bathroom shelf. Nits and lice on the lashes are often removed mechanically as well, gently lifted off the hair with fine forceps under magnification.
| Area affected | What's used | Key caution |
|---|---|---|
| Pubic, perianal, armpit, chest, beard hair | OTC 1% permethrin lotion or pyrethrins/piperonyl-butoxide mousse; repeat if live lice remain | Follow label timing; do not overuse |
| Eyelashes and eyebrows near the eye | Ophthalmic-grade petrolatum to lid margins; manual nit removal | Never apply insecticidal lice products to the eye area |
Whatever the area, treat it as a defined course and follow through even after the itch fades. Decontaminate the things that touched infested skin: hot-wash and machine-dry clothing, towels, and bedding used in the prior few days, since lice and nits can briefly survive off the body.

Prevention and stopping reinfestation
Tell every sex partner from the past month so they can be checked and treated, and avoid sexual contact until both of you are treated — otherwise you'll trade the lice back and forth. Treating one person while the other goes untreated is the single most common reason crabs come back. Wash and dry shared bedding and clothing, and don't share towels or bed linens until everyone's clear.
For ongoing prevention: condoms used every time lower the risk of the sexually transmitted infections that often travel with lice exposure, and routine testing catches the ones that cause no symptoms. Condoms don't fully prevent pubic lice, though, because the insects live on hair outside the area a condom covers — which is why partner treatment and not sharing personal items matter more here.
When to see a clinician
Get medical care rather than self-treating if lice involve the eyelashes or eyebrows, if symptoms are in a child, if you're pregnant or breastfeeding, if the skin is broken or looks infected, or if lice persist after a correctly used over-the-counter treatment. An eye exam is the safest way to confirm and clear a lash infestation, and a clinician can also rule out look-alikes such as ordinary eyelid inflammation.
