Sawyer Insect Repellent Spray with Picaridin is safer on gear and equipment than DEET, plus it gives up to 14 hours of protection. Sawyer uses 20% Picaridin as the active ingredient for this repellent. Picaridin is a promising new insecticide and its effect is similar to DEET for use against mosquitoes and is more effective than DEET for use against flies. It is safer on gear and equipment than DEET; it won't harm fishing line, lures, watches, sunglasses, fire arm finishes, or most synthetic fabrics. At 20%, this long lasting topical lotion is effective against mosquitoes, ticks, biting flies, gnats, chiggers and fleas. It goes on smoothly and dries quickly without leaving any oily, greasy, or sticky residue. The Sawyer Insect Repellent Lotion with Picaridin is virtually odorless and has a mild citrus scent added to it which quickly evaporates away.
