I use the Sawyer Peremethrin and have used it for two seasons tick free. I use at least a can on my pants,jerseys,shirts,knee length socks which I tuck my pants into. I spray my 3D leaf suit which I wear bow,gun and recently in my Turkey hunting and this gives me a second barrier of treated cloths. I watch ticks drop after a few seconds on the treated cloths so I like others think your not getting a good coating on your cloths. Always spray the leg areas the heaviest,I spray these areas twice. Take care!
