Buck Fever Synthetics LLC makes synthetic deer hunting scents and scent elimination sprays and wipes. We are located in the northern lower peninsula of Michigan. We are avid hunters and have invested years of research and development into products that we are proud to say really stand out from other deer scents and human scent removers on the market today. Our synthetic deer lures have an infinite shelf life and they will last for months in the woods. They are made to crystallize upon use and will reactivate via any moisture (rain, dew).
