Body lice frequently lay their eggs on or near the seams of clothing. They must feed on blood and usually only move to the skin to feed. They exist worldwide and infest people of all races and can therefore spread rapidly under crowded living conditions where hygiene is poor (homeless, refugees, victims of war or natural disasters).
