Can deer smell food from a distance?
Because there was only open space between the fence and the woods, we concluded that whitetails are able to detect certain odors at least 425 yards away. Having observed this over a span of years, it's my belief they probably smell odors at far greater distances.
Whitetail Deer Have a Great Sense of Smell
A deer's nose has 297 million olfactory receptors whereas a dog has 220 million. Humans, for comparison, have a mere 5 million. Olfactory receptors are nerve cells that line the inside of our noses.
Estimates state that a whitetail deer can detect human scent for up to 10 days after it's left.
In normal conditions, vibrations produced by walking in leaves and branches can conservatively travel 300-400 yards, and slight metal clanging (like when hanging stands and climbing sticks) up to a half-mile, all within a whitetail's audible frequency range.
It takes between 1 or 2 days for deer to find corn, but in some cases it can happen sooner, if the area is well traveled.
Not only is deer corn highly consumed and well received by whitetails in almost every habitat across the continent, but it's also one of the cheapest options for hunters. Corn contains several of these essential nutrients for whitetails that improve their health and ability to survive leading into winter.
From larger plots of forage soybeans covering 10 or more acres, to small parcels of broken tree canopy planted to brassica; various crops including corn, milo, turnips, peas, clover, and alfalfa will attract and keep deer. One of the surest ways to attract deer is through their stomach.
Any whitetail deer hunter can attest a mature buck seems to have a sixth sense that alerts them to our presence. There seems to be something in addition to the super-hero sense of smell, hearing and eyesight that they already possess.
Deer are attracted to the smell of soil as is, but if you want to up the attraction factor, pour some buck or doe urine, or scrape starter into it. This will create an exceptional trail camera site, as bucks will continue to check the scrape every time they pass by or are in the area.
More often than not, a deer will smell you before seeing or hearing you when you're in the tree stand. One of the most tried and true hunting tips is to play the wind when you hunt. If you're always downwind, they can't smell you.
Can deer smell my snacks?
Deer have a great sense of smell and even if you are sitting 20 feet in the air in your tree stand, the likelihood of a deer smelling your food is great.
For example, if a hunter goes in and hunts the same stand day after day, for the entire season, it becomes susceptible to stand burnout. This happens more often than we might think. It doesn't matter how good the spot is or how many deer you see in there.
It's widely believed that our urine is loaded with human scent and that deer will head for the hills when they get a whiff of it. Home remedies for keeping deer out of gardens include urinating around the perimeter of it. Yet there is research that indicates some deer may not be bothered by it at all.
Deer are creatures of habit and may bed in the same location repeatedly. One exception is during periods of the rut when bucks are on the move searching for estrus does and defending their hierarchy.
ANSWER: Under normal conditions, a deer can smell a human that is not making any attempt to hide its odor at least 1/4 mile away. If the scenting conditions are perfect (humid with a light breeze), it can even be farther.
This means they don't need to move their eyes at all. With the head stationary, deer can see at a 300 degree angle around. A slight turn of their head can reveal the other 60 degrees.
A bear's sense of smell is so acute that they can detect animal carcases upwind and from a distance of 20 miles away. You should just assume that they can smell the food in your food bag too.
Researchers at Mississippi State University found that a deer's sense of smell, like a dog's, can be anywhere from 500 to 1,000 times more acute than a human's. Furthermore, scientists say that whitetails have thousands of sensitive receptors in their nostrils, which they use to sort out up to six smells at one time.
