Head lice are easy to kill. You just need the right information.
By Adam Ward
Myth No. 1: Lice can jump and fly.
Lice crawl. Period. They move from one head to another by grabbing onto a passing hair with one of their six claws. In order for that to happen, two heads have to be close enough for hair to touch. So if you don't touch heads with with an infested person, the chances of you getting lice are extremely low.
Myth No. 2: Only kids get lice.
Based on treatments at Lice Clinics of America, just half of head-lice infestations happen to school-age kids. The other half happen to parents (usually the moms) and older siblings. Teenagers and college students who spend a lot of time putting their heads together for selfies and other activities are also not immune.
Myth No. 3: Lice spread disease.
They don't. There are three types of lice that feed off humans, and only the body louse can transmit disease (which can kill you).
Myth No. 4: Lice can infest a house.
Research shows that most head lice, which need to feed on human blood every three to four hours, die within 15 hours off their host. If a louse accidentally comes off a head, it is highly unlikely that it will be able to make it back onto a head before dehydrating and dying.
Myth No. 5: Pesticides can't kill Super Lice.
So let's get back to this Super Lice myth. There are lots of pesticides around the world that can kill these lice. Unfortunately, most aren't widely available in the U.S. or approved by the Food and Drug Administration.
Seventy-two percent of OTC lice products sold in the United States contain either permethrin or pyrethrum. These pesticides used to be extremely effective at killing lice. But after decades of overuse, they now are effective less than 45 percent of the time, and that is after multiple treatments.
In the past decade, a number of "all-natural" products have hit the U.S. market to address this problem. Unfortunately, many of these products use essential oils to kill lice. These products should be avoided because the essential oils kill lice using neurotoxic means, and do so without regulation by the FDA for safety and efficacy.
