Question: are crabs the same as nits?
Answer: Pubic lice are sometimes known as crabs because they have 2 large front legs that look like the claws of a crab. These are used to hold onto the base of hairs. The lice lay their eggs (nits) in sacs that are stuck firmly to hairs and are a pale brownish colour. When the eggs hatch, the empty egg sacs are white.
