Pesticide Overuse Has Led to a Huge “Super Lice” Outbreak
Like antibiotics, pesticides are overused and rendered ineffective
Don’t freak out, but “super lice” resistant to the pesticides commonly used to kill them are marching across the United States. They’re not going to kill you, they’re just really gross, they make you itch, and if you’re a parent, they could challenge your sanity.
So far, the super lice outbreak, which began last year, has spread across 25 states, and it exists because the chemical treatments used to get rid of the pests have been overused. The bugs can’t be killed using pyrethroids, the traditional method of treatment. 
A 2014 study by the University of California, Davis, showed that of the urinary samples taken from adults and children in 90 California families, 2/3 had breakdown products of pyrethroids. In 2009, the Environmental Protection Agency (EPA) found pyrethroids in more than 3,500 registered commercial products. 
According to Beyond Pesticides’ Chemical Watch card, pyrethroids are a synthetic version of a chrysanthemum extract, which are designed to be more toxic and take longer to break down. The chemicals used to be 100% effective against lice, but now they only work about 25% of the time.
Pyrethroids are not terribly safe, either, but I’ll get into that later.
Daniel McCrimons, a pediatrician in Sacramento, California, told Good magazine:
“The lice themselves have sort of built up a resistance to conventional over-the-counter treatments that most patients use for the treatments.”
Things have gotten so bad that parents are practically going bald – not from a lice infestation, but from ripping out their own hair in frustration. Kids are experiencing infestation after infestation, leading parents to take them to lice clinics, where the insects are killed via dehydration.
These clinics use AirAlle, a treatment recently approved by the Food and Drug Administration (FDA), which uses heated air to kill the little buggers and their eggs in about an hour. Usually, just one treatment is needed. But it’ll cost ya: Lice Clinics of America charges around $170. 
However, if you have the cash, AirAlle is a lot safer than pyrethroids. Pyrethroids are toxic to humans and dogs, and can be lethal to cats. The chemicals can harm the nervous system and, at high amounts, can cause headaches, breathing difficulty, nausea and vomiting. 
Also, according to Chemical Watch card, pyrethroids are endocrine disruptors which have been linked to breast cancer, and may adversely affect reproduction and sexual development, and interfere with the immune system. 
Some research suggests that pyrethroids may negatively affect kids’ behavior. A 2014 study on Canadian children found that exposure to the pesticides were linked to behavioral problems reported by parents.
They’re not nice to the environment either, having been shown to potentially kill bees, birds, fish, and other water-dwelling creatures.
If you’re worried about the crazy, mutant super lice invading your child’s scalp and you’d rather not smear a possible human carcinogen over his or her head, here are a few tips for preventing an infestation, as well as some home remedies for head lice:
- Teach your children not to share combs, brushes, pillows, hats, or helmets.
- The idea of bugs in your child’s hair might give you the overwhelming urge to shampoo them until foam comes out of their noses when they sneeze, but squeaky-clean hair is easier for lice to attach their eggs to.
- Nit-pick. Like, in the literal sense. This isn’t the time to nag Junior about his grades or Suzy about her taste in boys. Get a comb and physically look for lice. Seek and destroy, moms and pops. It takes a while, but at least it’s chemical-free.
- If you see hair on the floor or on the furniture, vacuum it up. Wash human bedding in hot water. Toss animal bedding and clothing in a hot dryer for 20-30 minutes.
