Treatment of clothing with a permethrin spray for personal protection against the western black-legged tick,Ixodes pacificus (Acari: Ixodidae)

Abstract

The synthetic pyrethroid, permethrin, when applied to clothing with a pressurized spray at an application rate estimated previously to be 4 μg a.i./cm2, was found to be 100% effective for personal protection against all three parasitic stages of the western black-legged tick,Ixodes pacificus Cooley and Kohls. This tick has been implicated as the primary vector of the Lyme disease spirochete (Borrelia burgdorferi) to humans in the far-western United States. Periods of exposure to permethrin-treated cloth as brief as 10 and 45 seconds incapacitated 100% of subadult and adult ticks, respectively, within 1–3 h post-treatment. Under field conditions, permethrin appareatly does not repel questing adult ticks, though 100% of ticks recovered from treated clothing after exposures as brief as ≤15 seconds were moribund 1 h later.
