Are you wondering how far can a deer smell?
Any seasoned hunter will tell you, scent control is critical.
But many hunters still don’t take the extra effort required to mask their scent.
Even hunters that do can be doomed due to a sudden shift in wind.
As we will discuss below, deer have a much better sense of smell than humans.
This knowledge can be the difference between a successful hunt and going home empty handed.
How Far Can a Deer Smell?
The jury is still out on a exact distance, but consensus is that deer can smell somewhere between 1/4 and 1/2 mile depending on the scent and wind.
Humidity can play a role as well, with more humid climates making it easier for deer to smell.
Researches have been trying to answer this question for quite some time.
What they have found is that a deer’s sense of smell is similar to that of a dog’s…
Which is somewhere between 500-1000 times better than us humans.
Deer Smelling Superpowers
Deer have approximately 300 million olfactory receptors compared to humans who have only 5 million.
The practical implications while deer hunting are important.
1/4 mile is 1320 feet, or 440 yards.
This is a long shot for a rifle, and an impossible shot with a bow.
Add in even a light breeze and your hunt might be doomed.
So what do we do as hunters knowing that deer can sniff us out from such a far distance?
What You Can Do About Your Scent
Luckily for us hunters, not all hope is lost.
There are a number of different strategies we can use to help prevent us from getting scented.
Research on Deer’s Sense of Smell
Deer are able to detect human odor we emit through skin that evaporate and are called volatile organic compounds (VOCs).
Dr. Bronson Stickland of Mississippi State University has studied this in depth.
In this study, researchers tested clothing that had been tested with a scent blocker vs. those that hadn’t.
They found that the sprays work by reducing levels of 29 key compounds found in human scent.
Hence your scent matters, and scent blockers do work.
Best Scent Blockers
A complete review of the best deer scent blockers warrants its own article, but here is my favorite at the moment.
Scent Killer Autumn is a great all-around scent killer that actually works.
Using it is a simple as spraying your hunting clothing and gear prior to your hunt.
With a thorough coating of spray, you should be good to go for a few days of hunting.
Just be sure to re-spray your gear if you wash it.
Wind scent drift is nothing new to hunters.
Hunters have been using techniques to use wind direction in their favor for ages.
But it is worth reiterating here.
If at all possible, you want to make sure to have the wind blowing into your face.
When the wind direction is coming from behind you, the chances of a deer in front of you picking up your scent increase dramatically.
The usefulness of ozonics are still up for debate among hunters.
I did a breakdown of my 5 favorite Ozone generators for hunters in another article.
As we discussed above, the need to mask our scent as hunters is real. There is no getting around that.
I believe anything we can do to improve our chances is worth it if it is within your budget.
- Package include HR 230 | Standard Battery (up to 4 hrs in Boost Mode and 5 hrs in Standard Mode) | Battery Charger | Tree Mounting system | Blind bracket mounting system | Integrated EZ mount attachment.
- NEW UPGRADE: Integrated Pulse Technology: Balances time and oxidant concentration to ensure the proper amount is deployed to deodorize your gear.
- Features two levels of ozone output for blind hunting and treestand hunting (boost mode).
The Ozonics HR-230 is a great unit, especially if you are hunting from a treestand.
The batteries last up to 5 hours and many hunters have great things to say about it.
If you are trying to do everything you can to control your scent, it is worth a look.
How Can We Use Deer Sense of Smell to Our Advantage
Another way to look at the excellent smelling abilities of deer is to see if we can use it to our benefit.
Apples, corn, and other types of attractants can be used to attract deer into the area you hunt.
