A New Way To Fight Head Lice – Part 1 of 2
A New Way To Fight Head Lice. Insecticide-treated underwear won’t wipe out lice infestations in derelict shelters, according to a new study. The scheme initially showed some success, but the lice soon developed resistance to the chemical, the researchers said. Body lice can spread through direct contact and shared clothing and bedding, and the problem is worsened by overcrowded conditions.
The study, which was published online Dec 4? 2013 in the record book JAMA Dermatology, examined the impact of giving homeless people underwear treated with the insecticide permethrin. Forty participants were given brand-new underwear treated with the insecticide and 33 others received untreated underwear. They were checked 14 and 45 days later. On day 14, the researchers found that 11 of the 40 population given treated underwear were free of body lice, compared with three of the 33 who received untreated underwear.
