A study conducted by researchers at the University of North Carolina at Chapel Hill and the University of Rhode Island evaluated the effectiveness of long-lasting permethrin-impregnated clothing for reducing bites from blacklegged ticks (Ixodes scapularis) among outdoor workers. Their findings showed as much as 65 percent fewer tick-bite encounters among study participants wearing the treated clothing compared to those wearing non-treated clothing.
