I am into scent control quite a bit having hunted very high-pressure small parcels of land my whole life other than the occasional time of hunting somewhere outside my area. I got into it when I was a very young hunter, and have seen the benefits way too many times to stop. I saw changes as soon as I started being more careful with my clothing, wearing rubber boots and avoiding strong smells I can smell myself. I also started seeing and killing more deer than others hunting the same area. I had read some articles on it in some hunting magazine back in the 70’s. This was before the internet, cable tv, scent control clothing, and all the stuff on the market now. It was before I had ever seen a compound bow.
I do a lot with clothing and have some scent-loc type stuff, but mostly because I got them on clearance or used and liked everything about them. I figure the scent control will not hurt if it works, but I don’t depend on it. I keep everything as sealed and scent free as possible. Us the air tight containers, wash with the soaps, use the spray, rubber boots, dress in the field, pack in top layers, trim stuff so I don't touch it, and so on. It takes a little time and prep, but cost is not that big a deal.
I hunt the wind as best as I can. I approach stands with the least possible impact. But, I often have one access point to a property and limited ways to get through it. If I always waited for the best wind and approach to a stand, I would hunt about 3 days a year. Having more small parcels to hunt does help make best choices, but sometime I have to hunt where I can when you can. If I don’t take care of my scent, I will not be seeing much for long.
When I have a spot I can get to with very little impact on deer due to where I walk and wind direction, I will cut back a bit on my scent control. Last hunts in a spot for the year before gun season opens often finds me not bothering with being too careful as long as I am hunting the wind. If I had a big track of land with lots of options for where to hunt and how to get there, I would do less, but still try and not stink up the area unnecessarily. You can walk right into a great spot and screw it up before you get a chance to hunt it if you are reckless with scent.
I think scent control matters a lot in the areas I hunt. It is not total eliminate of scent I am after. It is fooling them into thinking you are a safe distance away or that you passed through a long time ago. That makes a huge difference. In less pressured area I think even trace smells send animals a long way off. They tolerate very little if any human scent. I guess it matters little if you bother much with scent control and hunt different spots all the time in those kinds of areas.
Deer smell people all the time in high-pressure populated areas. Where I hunt, they smell someone most days with hunters all around our perimeter. Animals figure out how much smell is trouble and develop some tolerance. They sniff everyone out in the dark to see what they are doing. They then change travel paths to work around everyone and stay away from hot zones, blinds and stands in daylight. As long as they have areas they feel are reasonably safe, they will move in day light at least a little. The lower the concentration of smell in an area the less likely they will be to spook or stop using it. I have shot deer that smelled me, but were not alarmed thinking I was a long way off or had passed a while back.
I see exactly what happens when other people hunt the same land I do and hunt the wind only. I have had them make comments about my process thinking I am crazy to bother with that stuff. The result is the place shuts down, and we all see nothing after they hunt a couple days. They are hunting the wind, but leaving too much scent behind. I have to work like crazy to kill something and they get zip. They see the deer where I hunt so move in there the next year. No deer to be found. I move to where they used to hunt and see deer. On my own hunting the same place without others with me, I see deer keep moving through the season. They are more cautious due to the pressure around the area and my traces of scent, but I see them still moving in daylight if I am carful.
Two years ago I had a search party looking for a deer come searching through the small properly I hunted after work. They went through the area touching stuff walking around in the cover. I did not see another deer the rest of the season there. It doesn’t take much to trash a small area for a long time in pressured areas.
I have forgotten to spray my boots off or walked ground with human activity smells on a driveway or yard area and had deer pick right up on my track and track me to my stand and spook. I have done all the right things and had them notice I had passed sometimes, but not be alarmed about it. They pick up something and track me a little, but figure it is old scent and relax. I have seen it many times.
Last week I had coon walk up to the base of my tree and pick up my scent where I sat my bow on the ground. He was scared and circled very cautious. Then he calmed down and walked out on the trail I walked in on with no concern whatsoever. I think he smelled me on the trail, but much less scent than at the base of my tree so figured he was heeding away from any threat. The same thing happened this week with a house cat. It walked in on my trail fine and then right away noticed where I had set my bow on the ground. It almost jumped with surprise. Sniffed around, looked around, and walked off.
I have pulled off a head cover while watching a deer I was not going to shoot and had them explode out of there because it was a little downwind with some light swirling of air in the area. The scent level came up and that spelled trouble. The same for opening a top layer to cool off. I have seen it too many times no to firmly believe that there is a tolerance deer in populated high pressure areas have for human scent. Stay in the acceptable level and you are good to go, but put out a little more scent and they are gone.
The best one ever was one time I had deer feeding in field corner. I was about 75 yd down the tree line with some flooded timber behind me with the wind hitting square to the tree line in my face. I did not think they were down wind at all with no chance to smell me. This spot, wind and deer location happens a lot. I have hunted the spot for over 30 years, and I was just hunting it yesterday so I know how the spot works out in the same conditions with deer in the same place. I don’t get busted. This time I had a cough going, and was having hard time muffling it. I decided to slip in a cough drop I had sealed in a plastic zip lock in my pack. I pulled it out of the bag, opened it and just as I got it in my mouth her nose went in the air, she looked my way, and exploded out of there. I could see a long way and there was no one in the area but me. Obviously, the air currents in the trees and pond area were drifting to her, but not enough for her to notice or care until I hit her with a strong smell. All those smelly chemicals we are around and put on our bodies have the exact same impact. I think they can be worse than small amount of human odor because they are so strong and travel so far without diluting. Put a bunch of that stuff on you, add some cooking smells, the dog, and you without a bath recently, and you can really smell up an area when you are there and long after you are gone.
I believe that those who think scent control is a waste of time either have not done it, or have not done it to a level to see what a difference it makes in populated areas. And, I do think the populated areas are a different thing than more remote areas. I suspect that the success of scent control is harder to realize where human scent is more out of place. Just like loud noises, motor vehicles and so on. I watch deer feed calmly as I listen to kids fighting, doors slamming, the quad going down the trail on the net property and so on. Makes me crazy to listening to it all, but the deer don't even seem to notice.
