According to scientists, super lice are infecting nearly double the number of states they did a year ago.
A study from last August showed them in 25 states, now that number is up to 42, including Maryland.
On average, 98 percent of lice in those states can survive traditional over the counter treatments. Their genes have mutated so they're immune to common insecticides.
One treatment option involves an FDA approved device that attacks the bugs' eggs, but not the skin of the scalp.
