Now, a new study by CDC researchers has found that just a minute or two of contact with permethrin-treated clothing caused ticks to become incapacitated or fall off fabric.
The research examined a variety of permethrin-treated clothing types and fabrics. It revealed that the items can be toxic to several species of ticks and at different stages in their life cycles, potentially keeping them from getting beneath clothing and staying next to skin long enough to bite.
