Don't listen to the people who talk down on Sent killer sprays... Sent Killer is popular for one reason... BECAUSE IT WORKS!!! I give a lot of credit to it last year. I took a big mature 9 pointer last year. I am afraid of hights so my tree stand is only 10 feet off the ground....
.... The deer was straight down wind of me and came within 20 yards before I put my arrow through him. before I went out that morning I really sprayed everything down with the sent killer...
Will sent killer work 100% of the time? Maybe not... But I know after last year I am going to use it 100% of the time!
Happy Hunting!
