Crabs, also known as pubic lice, are small, parasitic insects that infest human pubic areas, causing discomfort and embarrassment. They are typically found in the genital area, but can also be found in other areas with coarse hair, such as the armpits, beard, and eyebrows.
Characteristics of Crabs
Crabs are small, flat, and oval-shaped, with a grayish-white color. They have six legs, with the front two legs being larger than the others. Adult crabs are approximately 1-2 millimeters in length, making them barely visible to the naked eye. They have a distinctive pair of claws at the front of their body, which they use to grasp onto human hair.
Life Cycle of Crabs
The life cycle of crabs consists of three stages: egg, nymph, and adult. Female crabs lay their eggs, also known as nits, at the base of human hair shafts. The eggs hatch after 6-10 days, releasing a nymph that resembles a small adult crab. The nymph goes through three molts, shedding its skin each time, before reaching adulthood. The entire life cycle of crabs takes approximately 3-4 weeks.
| Stage | Description | Duration |
|---|---|---|
| Egg (Nit) | Laid at the base of human hair shafts | 6-10 days |
| Nymph | Goes through three molts, shedding skin each time | 2-3 weeks |
| Adult | Reaches maturity, begins laying eggs | 1-3 months |
Crabs are typically diagnosed through a visual examination of the affected area, where the presence of live lice, eggs, or nits can be seen. Treatment for crabs usually involves the use of over-the-counter or prescription medications, such as permethrin or ivermectin, which are applied directly to the affected area.
Treatment and Prevention
Treatment for crabs typically involves a combination of medications and hygiene practices. It is essential to wash and dry clothing, bedding, and towels in hot water and high heat to kill any lice or eggs that may be present. It is also recommended to avoid sharing personal items, such as towels or clothing, and to avoid close contact with an infected person until treatment is complete.
Medications for Crabs
There are several medications available for the treatment of crabs, including:
- Permethrin (Elimite): a topical cream or lotion applied directly to the affected area
- Ivermectin (Stromectol): an oral medication taken in a single dose
- Malathion (Ovide): a topical lotion applied directly to the affected area
