Kathy & Jan have been trail ride buddies for decades. Through years of research and many years of trials we developed a product that gave us peace of mind while we rode on tick infested trails together. The evolution of this product resulted in an even longer lasting, more effective design that we call TNT-Tick Natural Terminator. We have used this product for over 20 years without seeing an embedded tick and now will not ride without it. Because it has been so effective, we have decided to get TNT-Tick Natural Terminator out to the other people who love trail rides, hiking, or just keeping their animals and themselves tick free. Our patent pending formulation is what makes this product effective. All the ingredients are FDA Compliant.
