I am a believer in Sawyer Products and their Permethrin is a game changer. Treat your clothing before a trip, and it stays effective for up to 6 washes. Please note that it is toxic to felines until it is 100% dry. Treat outdoors or in a well ventilated area where it’s out of the way of pets and kids until it’s completely dry! Pair this with Picaridin lotion or spray for your skin and you’re golden for tick season.
