The best way to prevent an infestation of pubic lice is to avoid sexual or other close contact with infested people. Use of a condom or other forms of safe sex will not prevent the spread of pubic lice. It is important to be aware of any potential health concerns of all sexual partners. Maintaining a monogamous relationship can help reduce the likelihood of being exposed to pubic lice.

Pubic lice may sometimes be spread through physical contact with contaminated linens or clothing. Avoid sharing towels at the gym and sharing or trying on swimsuits. It is also important to wash bedding, clothing and towels regularly in hot water – at least 130 degrees Fahrenheit (54 degrees Celsius) – and dry on high heat for at least 20 minutes.

People diagnosed or treated for a pubic lice infestation should inform all sexual partners that they have been exposed to pubic lice. This can help prevent the spread of infestation.
