Scent killer has its own smell too, so I only use what is natural in the woods as a cover scent. I rub fir, cedar or pine bows on my hands and clothes depending on where I hunt and when sitting in Hardwoods I will rake the leaves over and apply fresh earth to my clothes. The wet leaves in a hardwood ridge have a strong oder, so I rub them on my clothes as well.
Even when using cover scent, I always try to use the wind in my favor!!!!!!!
