If you aren't washing your clothes in some kind of scent remover the deer are prob smelling you..or the UV brighteners in the laundry soap are spooking them. If you have lots of leaves clear a good trail around your bait pile within shooting lanes of your stand. Deer will use your cleared trail because its quieter...Get a trail cam out to see when the most activity and where its coming from...movement and if you spit your dip out...they might be smelling that but Ive heard other stories where the deer didn't mind about that...but movement for sure will throw them off..also clear a trail going to your treestand...you may be pushing them out when you go in...I usually go in 1 to 1.5 hours before dawn and 3 to 4 hours before dusk and sit till after dusk unless there are deer there...
