Deer are known for their elegant beauty and their keen senses, particularly for their acute sense of smell.

Deer have developed and sharpened their sense of smell to such a degree, that it has become an integral aspect of their survival capabilities. As a result, just how sensitive a deer’s sense of smell is has become an important topic of interest for both hunters and wildlife enthusiasts.

After all, the last thing you want if you need to get close to a deer is for the animal to detect human scent and run away. So,

How Long Can A Deer Smell Human Scent?

A deer can smell human scent for as long as 24 to 48 hours. The exact time that a deer can smell a human after they have passed depends on a number of environmental factors, such as wind direction, humidity levels, and even temperature.

Under normal scenting conditions, a healthy deer has an incredibly sharp sense of smell and will be able to detect a human from a considerable distance and for a considerable period of time.

This means that if you are a wildlife enthusiast looking to get a closer look, or a hunter looking to add another buck to their collection, you’re probably going to want to invest in some sort of deodorizing product and scent control to get close.

It’s important to note that the smell of your body is not the only factor that can reveal you to a wary deer. Other common smells, such as the smell of food you’ve recently eaten or the smell of your detergent, deodorant, or shampoo, can also give away your presence and cause a deer to run away.

How much noise you make can also affect how easily a deer can detect you.

Nevertheless, a deer’s sense of smell is probably its sharpest sense and so you must take precautions to minimize your scent when in the field if you want to get close.

Hide your smell to get close to deer

Getting Close To A Deer

Your ability to get close to a deer will depend on several factors, but the most important one is going to be your ability to either mask or reduce your particular aroma so that the deer is unable to pick it up with their sharpened sense of smell.

Here are two ways in which you can do just that.

Move Downwind

Deer are able to detect the smell of humans hours after the fact, so if you want to get close either for hunting or study, you are going to want to move downwind. By doing so, you can significantly reduce the likelihood that your target deer will be able to detect your scent.

If you lack the experience to detect which way is downwind, there are several tools at your disposal that can help. For example, you can use a wind indicator, such as a flag or ribbon, to determine which direction the wind is moving.

If you want to get fancy, you can use something like this Pocket Anemometer from WapoRich (on Amazon).

Just remember that there is no foolproof method when it comes to masking or hiding your smell from a deer. These animals rely on their sharp sense of smell to detect dangerous predators, food sources, and potential mates.
