Mutated 'Super Lice' Strikes 25 States in the U.S. as School Starts
As kids go back to school, something worse than homework and detention awaits many of them.

As school kids return to school, researchers are warning parents about a pest that may await them: super lice.
Scientists who study lice populations across the country have reported that the bugs found in at least 25 states have developed into creatures quite resistant to common over-the-counter treatments. The researchers reported those findings to the American Chemical Society this week.

Kyong Yoon, Ph.D., a Southern Illinois University researcher, was among those who uncovered the findings.
βWhat we found was that 104 out of the 109 lice populations we tested had high levels of gene mutations, which have been linked to resistance to pyrethroids,β Yoon said in a media release.

Pyrethoids are a type of insecticide that is commonly used to help control mosquitoes and other insects, such as lice. Yoon ultimately found that some lice populations were developing mutations that enabled them to survive exposure to the insecticides commonly used to treat children and adults who suffer from infestations.

Renee Wilson, manager of Hair Fairies Salon, told CBS Chicago that parents are βupsetβ and βstressed outβ because the over-the counter treatments donβt work.
βThey just want to give up,β Wilson said. βIf that bug is crawling around the head and then someone is giving hugs, sharing hairbrushes, or by that person, that bug can transfer like that.β
Solutions to fight back against lice still exist, Yoon said. Different chemicals, such as those available onlyΒ by prescription, still prove effective.
Even so, the researcher points out the spread of the βsuper liceβ bug serves as a warning.
βIf you use a chemical over and over, these little creatures will eventually develop resistance,β Yoon says. βSo we have to think before we use a treatment. The good news is head lice donβt carry disease. Theyβre more a nuisance than anything else.β
