Where do head lice come from?
Head lice have been around for thousands of years. As with any insect, they learn to adapt to their environment in order to survive. We are never going to be completely rid of them, but we can make managing them easier.
Do head lice live in carpets, clothes, hats or sheets?
No. Head lice very rarely fall from the head. They require blood to survive. Head lice feed three to four times a day and without blood, will dehydrate in six hours in a dry climate and 24 hours in a humid climate. An egg requires warmth to hatch and is the reason why they are laid close to the scalp. The further away from the scalp, the less likely they are to survive.
Is it true that head lice only like clean hair?
No. Head lice are not selective. They don’t care if hair is long, short, blonde, brown, washed this morning or last week. As long as they are warm, and have blood to drink, then they are content.
Why do you have to treat again in seven days’ time?
Head lice eggs take six to seven days to hatch. And when you treat, it’s easy to miss an egg or two. By treating again in seven days, you are aiming to kill and comb out any lice that have since hatched from eggs, which were missed.
What should I wash or treat at home?
As head lice only live for a short time off the head, the only extra cleaning needed is to wash the pillowslip on the hot cycle or place in clothes dryer. Head lice combs can be cleaned in water hotter than 60 degrees.
