No Fly Zone is a permethrin-based technology that may help prevent the spread of insect borne diseases by repelling insects. This technology is similar to the natural insect repellent found in certain chrysanthemum plants and works as a contact repellent affecting the insect's nervous system causing it to fly away before a bite can occur. The Centers for Disease Control (CDC) recommends using permethrin treated garments along with other precautions to reduce the risk of bites. Our No Fly Zone fabric offers distinct advantages over other repellent technologies because the technology is applied at the fabric level for durable and consistent protection.
