If you’ve ever had head lice, you’ll know that they aren’t easy to get rid of. So much so, in fact, they’ve managed to exist for thousands of years - head lice were even around long before human evolution (Better Health Channel 2018).

Head lice are small wingless biting insects. They live and breed in human hair and feed on blood from the scalp.

An adult louse can range from a whitish-brown to reddish-brown colour and is about two to four millimetres in length. Lice eggs, called ‘nits’, are oblong-shaped, white or brown in colour and attached to hair shafts (SA Health, 2019). The warmth from the human head acts as an incubator, causing the nits to hatch (Better Health Channel 2018).

Incubation Period

Once a female louse has laid her first eggs on a new host, they will hatch after seven to ten days. From here, the nits will progress through their short life cycle consisting of three stages: egg, nymph and adult. The total lifespan of a louse is only 32-35 days, but after mating, each female can lay three to ten eggs per day. These eggs will then hatch and continue the cycle (Health VIC n.d.).
