Lice remain in the egg for about 10 days. This is why we recommend using our goop every ten days, to kill them as they hatch.

After hatching, head lice are in an adolescent stage, also known as nymphs, for another 10 days. They do not switch heads or reproduce during this time.

Head lice only live off the head for about 48 hours. They starve to death without a human food source.

Head lice live off human blood.

Head lice evolved with humans, and have been around as long as humans have been.

Head lice are partially resistant to the pesticides in over the counter and prescription lice treatments.

OTC head lice treatments kill about 30% of hatched lice, and prescriptions kill about 78% of hatched lice. You are killing enough of the adults that you can’t find them anymore and think that you killed all the lice. In 2 months, you’ve gone through two life cycles, and you’re back to the beginning.

Head lice can hold their breath for 19 hours, so they can survive most home remedies.

Dimethicone has a different molecular structure and head lice aspirate on it. Additionally, dimethicone interferes with the moisture regulation system of the bug.

No, head lice glue eggs/nits to the hair they and will not ever fall out. They need to be manually removed.

Yes, head lice lay eggs that are commonly known as nits.

No, nits need the warmth and humidity of the human scalp to hatch.

No. When head lice are first born, their claws are not big enough to wrap around a hair so they stay on the scalp. You would have to rub your scalp against someone else’s scalp to spread babies.

No. However, head lice can only feed on one blood type their whole lives. If they feed on a different type of blood, they will die.

Yes. The mom louse moves over and lays eggs immediately, before eating.

Head lice like all hair, being clean or dirty doesn’t matter to them.

Lice do not care about a person’s skin color or hair type. They love everyone.

Yes. Head to head contact spreads lice regardless of hair length.

Only 40% of people will have an allergic reaction to lice spit and itch. Itching is NOT a good indicator of being lice free.

Everybody living in the house is at risk. Head lice can live on furniture for up to two days, and only need 3 seconds to switch heads.

Head lice are not bothered by tea tree oil. It *may* have worked in the past, but not anymore.

Not well. A pony tail leaves a lot of loose hair, especially if the person has long hair. It’s slightly better than nothing. Buns and braids are best for head lice prevention, or a haircut close to the scalp such as a buzz cut or short pixie.

Head lice only remain on top of surfaces. They cannot go through fabric, including bed sheets.

Lice will not go through the pillow case. If you’re worried, they can go in the dryer for 45 minutes on high, or vacuum or lint roll them.

Lice cannot go through sheets. If you’re worried, you can vacuum or lint roll your mattress.

Head lice sprays use the same pesticide as the hair treatment, and neither of them kill all the lice. Vacuuming or lint rolling is safer than spreading pesticide across your house.

Head lice die after 48 hours off the head. Aside from other cleaning, you do not have to wash all the clothes in your closet, just those items worn in the last 48 hours.

Head lice are very bad at crawling up furniture. They are usually held to cloth by static cling.

The nits lowest down on the hair shaft gives us a time estimation of how long you’ve had head lice. Lice lay eggs near the scalp, and hair grows 1/2 inch per month. 1 inch of nits = two months of lice.

Not necessarily. Some people can support a larger population of head lice than others. Still estimate by the hair shaft method.

Washing hair will dislodge some of the adult lice. It will *not* get rid of lice, but more adults remaining can lay more eggs, which will grow into adults, and so on. Therefore, someone who does not wash their hair will generally have more head lice than someone who does.

No, hair dryers do not have set temperatures and will either not be hot enough to dehydrate the eggs, or will be too hot and burn your scalp.

While hair straighteners get hot enough to kill eggs and lice, getting the straightener close enough to your scalp to kill eggs would also burn you.

5-10% of head lice nits are laid against the scalp. The hair has to grow out for the comb to fit under the nits. That’s why you have to comb every day for weeks to make sure head lice is gone. Combs with more space between tines will not catch every nit, which is why you should use a professional lice comb.

YES. Lice spread within 3 seconds, so you need to tell anyone you’ve spent time with.

There are many reasons why a particular person does not catch head lice. Some of it is luck, some of it is blood PH and chemistry. Haircuts, levels of physical contact with family members, sharing hair supplies, and bed sharing also affect the spread of lice. More contact means more opportunities to catch lice.

Current numbers are 50% of siblings, 80% of primary caregivers, and 20% of secondary caregivers will have head lice.

When you brush your child’s hair, for lice treatment or for daily maintenance, you cause a static charge that can stick head lice to your clothes. Then when you take off your shirt, you get them in your hair.

To avoid catching head lice while performing a head check, put your hair into a bun, and lint roll yourself after the head check is completed.

Nits will be a similar color to the hair when they are first laid. Dyed hair will have dyed nits that are still viable. Once nits hatch, they turn a whitish color, because the baby is gone.

Nits have an eggshell like any other egg and you can feel it break. A “popping” nit does not mean the egg was viable, just that you crushed the eggshell.

An adult louse can lay 2-10 eggs per day, but she only needs to mate once to lay eggs forever.
