Crabs are very small bugs that attach themselves to your pubic hair and bite your skin. Scabies are bugs that dig under your skin where they lay their eggs, often in the genital area. Crabs and scabies both cause extreme itching and can be hard to see. They are passed from one person to another during sex, but can also be transmitted by having contact with clothes, bedding, and towels that were used by an infected person.
There are over-the-counter and prescription creams that can get rid of crabs and scabies. These creams should be used as directed by your healthcare provider. Also, it’s critical to wash your clothing, bedding, and towels in hot water to avoid re-infection. Clothes that can't be washed (leather jackets, shoes etc.), should be stored in a sealed plastic bag for at least 72 hours.
