Insect Repellent: EPA-Certified Permethrin Protects Against Mosquitos, Ticks, Chiggers, Ants, Midges & Flies for over 70 Washes!

Our fabric is EPA-Certified and uses a long-lasting permethrin that is chemically bonded to the fabric, so there is No Odor or Residue. Even after 70 washes, our fabric still boasts over 85% retention of the permethrin treatment, so even though permethrin is non-toxic to humans, you can rest assured that it won't affect aquatic life or cats (For comparison, the average store-bought spray-on permethrin treatment only lasts up to 6 washes!)
