The primary natural treatment for body lice is to thoroughly wash the body with soap and hot water, according to Mayo Clinic. If this treatment doesn't work, over-the-counter remedies such as Nix and Rid are available.
It is important for people to remember that over-the-counter treatments for body lice may be toxic, so a person should attempt to use natural treatments first, explains Mayo Clinic. In addition to cleaning the body, a person needs to also wash clothing, bed linens and towels at a minimum of 130 degrees F, and dry them in a hot dryer for a minimum of 20 minutes. Items that are not able to be washed should be stored in a plastic bag, sealed and left for two weeks before opening.
Body lice typically do not cause major issues, but there are some complications a person should be aware of, claims Mayo Clinic. For instance, body lice may cause a secondary infection, since the insects bite into the skin to feed off blood. The skin also may itch, and when scratching the small open wounds, bacteria can be introduced. Another complication of body lice is changes to the skin. In this case, if the infestation is allowed to continue for a long period, discoloration and thickening of the skin may occur.
