Insecticide-Treated Clothes Effective against Disease-Carrying Ticks

(From CBS News)

Outdoor enthusiasts: Here’s a bit of good tick-fighting news just in time for Memorial Day weekend and the unofficial start of summer.

A new U.S. government study confirms that insecticide-treated clothes marketed for preventing tick-borne ills do, in fact, thwart the pests.

In lab tests of clothes bought from one manufacturer, researchers found that the garments either quickly caused ticks to fall off, or rendered them unable to bite.

The clothes were pretreated with permethrin, a synthetic form of an insect-thwarting compound from the chrysanthemum flower. It’s used in insecticide sprays and shampoos and creams that treat lice and scabies.

Several companies already market permethrin-treated shirts, pants, socks and other clothing, as a way to ward off disease-transmitting pests. The new study adds to evidence that the garments are indeed toxic to ticks, according to senior researcher Lars Eisen, of the U.S. Centers for Disease Control and Prevention.
