National retailer Mark’s has just expanded its first-in-Canada line of bug repellent clothing. Every piece is treated with a long-lasting permethrin-based solution that binds directly into the fabric. The treatment is odourless, long-lasting and good for 70+ washes. Mark’s says the permethrin treatment works as a proximity/contact repellent affecting the insect’s nervous system, and causing skeeters to fly away, and ticks to fall off, before biting. The line includes a variety of outdoorsy, Dad-friendly long- and short-sleeve shirts, pants, zip-offs, shorts and hats.
