I use scent while trapping alot.It works better on some animals and not so good on others.The main thing now-a-days with scent,is that you have to get it fom a real lure maker.Someone who knows what they are doing,and someone who uses fresh glands-urine-etc.There are synthetics all over the place.The market is there and cheep substitutes make it affoardable,and less effective.I dont use them for deer.Mabe i will when i get my first batch to work the way i want it to.....
Another 2 things to think about if you do have scent that works is
1. are there deer in the area?Calls and scents are what they are.Just because it says it attracts deer,doesnt mean they will move a mile to get to it.You have to be in the general vacinity with any animal,the stuff isnt magic.
2.Time of year matters too.They smell each other all year but only take an intrest in each other for a short period.
Its all got to come together-calls-scent-decoys-camo-location,and the lack of human odor.Even with all of that,Those deer may have fallen for that trick before.
