I killed my first deer thirty years ago. I remember it like it was yesterday. Homemade stand nailed between three trees, Blustery cold December predawn.
A big buck ran under my stand and out towards the fire road just before shooting light.
I was bummed, biggest deer I had ever seen and now he was gone. A few minutes later I saw him walking directly back to me, nose to the ground, smelling the Pete Rickard's deer lure I had put on my boots before I walked in that morning. Giant 8 point down, biggest deer killed on the land that year.
I was pumped on deer scents after that but 29 more years of hunting convinced me it is more or less hit and miss with mostly miss.
I have had some positive results. Deer sniffing a spot where I had put everything from store bought to homemade and also plain vanilla. But if I had to assign a percentage, I would say 90% no results at all.
I have better luck being scent free, making mock scrapes and keeping my eyes open.
I will sometimes still use a deer attractant but more often than not, I will do without.
