How long a scent blocker lasts depends entirely on the type of product. Active carbon and alloy clothing can remain effective for 3 to 8 years depending on care, while sprays, soaps, and deodorants typically last 2 to 3 years in storage and only a few hours to a day once applied in the field.
Things such as zeolite, engineered polymers, activated carbon and antimicrobial silver aren't science fiction. They are the latest in human scent control, and they've been proven in laboratory tests to prevent or eliminate human odors.
How long will my ScentLok suit last? The lifespan of the product really depends on how you use it. We roughly say that it should last 3-5 years; about what you would expect from other hunting camo. If you are a knee-walking, belly-crawling extreme hunter in the woods five months a year, the life span may be shorter.
Under optimal conditions, a deer can smell a human from over 0.50.5𝟎.𝟓 miles away. Because a deer possesses up to 300300300 million olfactory receptors (compared to a human's 555 million), their sense of smell is incredibly powerful.
Hunters note that ScentBlocker functions well for everyday hunts, but ScentLok's carbon system can be reactivated by heat, making it highly reusable. For those who use scent sprays or soap along with clothing, both brands can be part of a system, though ScentLok is considered more advanced.
ALS Enterprises, Inc., the maker of Scent-Lok® odor reducing carbon hunting apparel, has obtained a complete victory in the nine federal lawsuits that challenged Scent-Lok®'s ability to control human odor.
The best scent killer for deer hunting depends on your approach to scent control, but top-tier products use highly effective technologies to keep human odor from spooking game.
Deer primarily hate pungent smells that mimic predators or overpower their sensitive noses. Because deer rely heavily on scent for survival, strong-smelling deterrents make them feel vulnerable. The most effective scents include:
The 7-Day Rule is a strategy built around the fact that mature bucks often revisit specific scrapes, trails, or stand sites during the same 7-day period every year, sometimes down to the exact day.
If so, follow along.
Sitka is the overall winner for advanced layering, better weatherproofing, and long-term performance in tough terrain. ScentLok wins for scent control, tree stand sits, and affordability during whitetail season.
ScentLok is worth it if you treat it as an extra safety net to minimize your scent footprint, rather than an excuse to ignore wind direction. While no technology completely masks human odor from mature animals, independent and field testing confirms the activated carbon significantly mitigates your scent, which can buy you crucial extra seconds.
To reactivate your ScentLok carbon clothing, place your gear in a household dryer and cycle on medium heat for about 40 minutes. We recommend spraying the inside of your dryer with ScentLok Field Sprays to help neutralize any unwanted odors that exist in your dryer.
Deer are effectively red-green colorblind and struggle to see long-wavelength colors like red and orange. To a deer, these hues do not appear bright or vibrant; instead, they register as muted shades of yellow, gray, or brown.
Research done by Dr. Henry Heffner at the University of Toledo shows that deer can hear at levels of 54,000 hertz, unlike humans who can only hear up to 20,000 hertz on a good day. Simply put, a whitetail can hear noises that we don't even know we're making.
The best deer scent attractants for whitetail depend on your goals and the time of year. For general herd attraction, synthetic calming scents are favored. During the breeding season, rut-specific urine lures work best, while food-based attractants pull in hungry deer.
And since urine is one facet of our odor we have some control over, plenty of deer hunters take the logical step and pee in a bottle. But in recent years there's a ton of evidence that human urine doesn't bother deer a bit.
Deer are essentially red-green colorblind and have difficulty distinguishing long-wavelength colors like orange and red. However, they are highly sensitive to blue, ultraviolet (UV) colors, and solid white, all of which stand out in the woods and can trigger alarm or cautious behavior.
In theory, The 7-Day Rule works like this: A good buck walks along a certain trail and visits a scrape, and you either see him or get him on trail camera. One year from that date, he should be visiting the same scrape and walking along the same trail. That's the premise.
Bobbex Deer Repellent is widely considered the number one commercial deer repellent. Independent studies, including testing by the Connecticut Agricultural Experiment Station, found it to be 93% effective—ranking higher than any other brand and second only to a physical barrier.
Deer do not sleep in the exact same spot every night. Instead, they rotate between a few preferred bedding areas within their home range. This behavior helps them stay safe from predators, adapt to shifting weather conditions, and adjust to changing food sources.
Hunters have deemed this the “October lull,” a period when bucks become nocturnal and even more elusive than before. Perhaps hunting pressure is to blame. Whatever the reason, as the pre-rut and rut kicks into gear, the bucks come out of hiding and the lull is gone just as quickly and mysteriously as it arrived.
Early season: Food-based attractants like Apple Crush work best. Pre-rut and rut: Buck Bourbon 110 Proof maximizes scent reach. Year-round: Big Tine and BB2 Granular offer consistent results. Fall: White Oak Acorn Crunch is ideal for oak-heavy areas.
Yes, Dawn dish soap can help repel deer, but usually only when used as an ingredient in a homemade repellent spray. Dawn on its own is not an effective deterrent, but its sticky formula makes it the perfect "sticker" to help foul-tasting or smelly ingredients adhere to plant leaves.
Hunters mask human odor using a combination of scent-free hygiene products, carbon-lined or odor-neutralizing clothing, and localized cover scents. Popular strategies include:
