The cause of head lice infestations in children is not related to cleanliness. [5] Other animals, such as cats and dogs, do not play a role in transmission. [4] Head lice feed only on human blood and are only able to survive on human head hair. [6] [5] When adults, they are about 2 to 3 mm long. [8]
From each egg or "nit" may hatch one nymph that will grow and develop to the adult louse. Lice feed on blood once or more often each day by piercing the skin with their tiny needle-like mouthparts. While feeding they excrete saliva, which irritates the skin and causes itching. [8] Lice cannot burrow into the skin. [citation needed]
Adults are 1.5–2.0 mm long and flattened. They are much broader in comparison to head and body lice. Adults are found only on the human host and require human blood to survive. Pubic lice are transmitted from person to person most-commonly via sexual contact, although fomites (bedding, clothing) may play a minor role in their transmission. [4 ...

[1] Outside their hosts lice cannot survive more than 24 hrs. [23] The time required for head lice to complete their nymph development to the imago lasts for 12–15 days. [1]
