Pubic lice can be treated with natural methods, though they require more patience and repetition than conventional insecticides. A combination of oil-based suffocation, manual removal, and thorough home decontamination gives you the best chance of clearing an infestation without prescription or over-the-counter chemicals. One clinical study found a natural oil-based remedy was 92.3% effective against lice, matching the 92.2% success rate of a conventional pesticide treatment.
How Pubic Lice Spread and Survive
Pubic lice (often called crabs) are tiny parasites, only 1.5 to 2 mm long, that live on coarse body hair and feed on blood. They spread primarily through sexual contact, though bedding and clothing can occasionally play a role. A female louse lays about 30 eggs over her 3- to 4-week lifespan, gluing each one directly to a hair shaft. Those eggs hatch in roughly a week, and the nymphs go through three molts before reaching adulthood.
This life cycle matters for treatment. Killing the adult lice is only half the job. The eggs (called nits) are dark brown, under 1 mm long, and cemented to hair so firmly that even shaving won’t reliably remove them. The CDC specifically notes that shaving, waxing, and sugaring will not get rid of pubic lice. Any natural treatment plan needs to address both living lice and the eggs they leave behind, which means repeating the process over multiple sessions.
Oil-Based Suffocation Treatments
The most practical natural approach is coating the affected area with oil to suffocate the lice. Coconut oil is the most commonly used option. The lauric acid in coconut oil has lice-killing properties, and the thick texture physically blocks the breathing holes lice use to survive. Apply a generous layer to the entire affected area, cover with a barrier like plastic wrap or tight-fitting underwear, and leave it in place for at least eight hours. Overnight is ideal.
Coconut oil alone is less effective against nits. To improve your odds, mix in a few drops of an essential oil with known insecticidal properties. Tea tree oil is the best-studied option. Research published in Parasitology Research found that a 1% concentration of tea tree oil killed 100% of lice within 30 minutes. Anise oil and ylang ylang oil have also shown effectiveness. The clinical trial that matched conventional pesticides used a blend of coconut oil, anise oil, and ylang ylang oil applied three times at five-day intervals.
How to Dilute Essential Oils Safely
The skin in the pubic area is significantly more sensitive than the scalp, so you should never apply undiluted essential oils to this region. Neat application can cause allergic reactions, chemical burns, or sensitization that makes your skin permanently reactive to that oil. A safe starting ratio is roughly 3 to 5 drops of essential oil per tablespoon of carrier oil (coconut, olive, or almond). Test a small patch on the inner thigh first and wait 24 hours before applying to a larger area. If you notice burning, redness, or swelling, wash it off immediately.
Manual Removal With a Fine-Toothed Comb
After each oil treatment, you need to physically remove dead lice and nits. The CDC recommends using a fine-toothed nit comb or your fingernails to pull nits off the hair shafts. Most nits will still be attached to hair even after successful treatment, so skipping this step leaves viable eggs in place.
Work through the hair in small sections while it’s still coated in oil, which makes the comb glide more easily and loosens the glue holding nits in place. Wipe the comb on a white paper towel after each pass so you can see what you’re removing. Pay attention to the base of the hair shafts near the skin, where the newest eggs are laid. This process is tedious but critical. Plan to spend 15 to 20 minutes on it after every treatment session.
Treatment Schedule for Full Clearance
A single treatment will kill most adult lice but won’t eliminate eggs that haven’t hatched yet. Because nits take about a week to hatch, you need to repeat the full process (oil application, overnight suffocation, combing) at least three times at five-day intervals. This schedule ensures you catch newly hatched nymphs before they mature enough to lay their own eggs.
Here’s a practical timeline:
- Day 1: First oil treatment overnight, followed by thorough combing in the morning
- Day 6: Second treatment to kill any nymphs that hatched from surviving eggs
- Day 11: Third treatment as a final pass to catch any remaining stragglers
- Day 16: Inspect carefully. If you still see live lice or fresh nits close to the skin, repeat once more
The five-day spacing is tight enough to catch nymphs before they reach reproductive age but allows time for eggs to hatch so the nymphs are vulnerable to the oil treatment.
Decontaminating Your Home and Belongings
Treating your body without cleaning your environment risks re-infestation. On the same day as your first treatment, wash all bedding, towels, underwear, and any clothing that touched the affected area in the previous two days. The water temperature needs to reach at least 130°F (54°C), and use the high-heat dryer cycle afterward. This combination kills both lice and eggs.
Items that can’t be machine washed (pillows, stuffed items, delicate fabrics) can be sealed in a plastic bag for two weeks. Pubic lice can’t survive long without a human host, so this waiting period starves any remaining lice or allows eggs to hatch and die without a blood source. Vacuum upholstered furniture and mattresses as an extra precaution, though transmission from furniture is rare.
Treating Sexual Partners
Anyone you’ve had close physical contact with in the past month should be checked and treated at the same time you treat yourself. If only one person treats the infestation, lice pass back and forth between partners indefinitely. Both partners should begin treatment on the same day and avoid sexual contact until the full treatment cycle is complete and neither person shows signs of live lice or fresh nits.
What Natural Remedies Can and Cannot Do
Natural oil treatments work well against adult lice and nymphs. The clinical evidence is genuinely encouraging: a coconut and essential oil blend performed identically to a conventional pesticide spray in a controlled trial of over 100 patients. The limitation is nits. Oils are less reliable at penetrating the hard shell of an unhatched egg, which is why the repeat treatment schedule is non-negotiable. If you skip follow-up sessions, surviving eggs will hatch and restart the cycle.
If you’ve completed three rounds of treatment over two weeks and still find live lice, the natural approach may not be sufficient for your infestation. Heavier infestations, or lice that have spread to other coarse body hair like chest hair, leg hair, or even eyebrows, can be harder to reach with topical oils alone.
