'Super Lice' Strike in 25 States

Is your head itchy yet?

"Super lice" are infesting the nation and have appeared in half the country, according to an NBC affiliate in St. Louis, Missouri.

The insidious creatures are resistant to chemicals present in most over-the-counter treatments that reportedly could cure 100 percent of lice cases back in 2000.

But times have changed, according to KSDK. And while a more advanced, FDA-approved treatment to counter the super lice is available and is sometimes covered by insurance, it can cost nearly $200.

"Don't share hats, don't share hairbrushes," Claire Roberts, CEO of Lice Clinics of America, told the station. "Try to avoid the actual contact with hair or another head. That's how the lice are transferred." 

If a case of lice does rear its ugly head in your house, here are a few things you can do. KSDK says experts recommend vacuuming thoroughly, throwing stuffed animals in a hot dryer for 20 to 30 minutes and washing bedding in hot water. MSN
