Crab lice are spread by intimate contact – either through intercourse or simply by sharing a bed with an infected person. However, there are cases of crab lice which cannot be explained by intercourse or sharing a bed. The lice rarely leave their host but they cause itching which can result in them being scratched off along with the hair they cling to. During the first few hours, those homeless crab lice might climb on to the other people who come into contact with the bedding, the clothing or the toilet seat on which the lice landed. Crab lice are no longer as common as they have been. This is attributed to the shaving of the pubic hair, which has become increasingly common and reduces the amount of hair for lice to live on.
