I have used them all, from Primo’s to Sent Killer but about three years ago I found a product that beats them all.... BioExtreme. It comes in one bottle as a concentrate and you add water to it. You can use it in the shower, the bath, the washing machine and in the field... all in one bottle. Plus it only cost about 19 bucks for a 32 ounce serving... I have never been busted by an animal since and this includes African game.... This stuff works and runs circles around all the others...Oh yea and as long as there is heat (body). oxygen, and moister it never quits working... It just can not be beat in my book.
