Best Answer

Head lice require a certain level of heat and humidity to survive and for their eggs (nits) to properly incubate.

Because it takes 7-10 days for the eggs to hatch, finding nits more than 1/4 inch from the scalp usually are not viable. However, some can incubate longer, especially in more humid climates that replicate the ideal environment.

Why does head lice live on your head?

Head lice enjoy living in your hair where it's safe and warm, they live close to your scalp where they have easy access to your skin where they use their serrated claws and teeth to cut into your flesh and drink your blood, it's like living above your favorite restaurant where they give you food for free and right to your bedside.Plus using the hairs surrounding them, it's easy to lay eggs right there.Look out!

Can cats carry human lice?

no Pet's cant get lice. It depends on what your pet is - if it is a sheep, goat or bird than yes it can get lice. Human head lice cannot survive on pets. They need human blood to survive and live. Lice are extremely fragile in the environment (dehydrate VERY quickly) and cannot live longer than 24 hours without a human blood meal (they don't live on pets). Focusing on items worn in the last 24 hours, bedsheets, combs/brushes will cover your possible exposure from the environment. Experts believe lice transmission from inanimate objects to be less than 2%. So cover your bases but don't fine tooth comb the carpet!
