If you have field-dressed a rutting buck and caught that sharp musk off the inside of the hocks, you already know the tarsal gland — one of the strongest social signals a whitetail leaves, and easy to misuse.
This guide covers what the glands do, when the scent helps, how to harvest and store them, how commercial lures compare, Wisconsin-friendly setups, and current Wisconsin DNR scent and carcass rules.
What tarsal glands are and why they matter
Tarsal glands sit on the inside of a deer’s hind legs, just above the dewclaws on the hocks. The hair holds glandular oils and urine. In the breeding season, bucks (and sometimes does) rub-urinate — rubbing the hocks together while urinating so urine soaks the tarsal tufts.
That mix is the dark, strong “rut smell” on mature bucks. Hair darkens as oils and urine build through fall. Dominant bucks advertise status and breeding readiness; other deer read those cues at scrapes, on trails, and when a buck walks cover.
For hunters: tarsal scent is a social and breeding signal, not food bait. Used well, it can pull or hold a competitive buck. Used poorly — wrong wind, wrong season, too much scent, or illegal scent — it educates deer and ruins a setup.
When to use tarsal scent in the Upper Midwest
Timing matters as much as the scent itself. In Wisconsin and neighboring Upper Midwest states, think in three phases:
Pre-rut (roughly mid-October into early November)
Bucks rub, scrape, and check does more, but chasing is not constant. A light drag or mock scrape on a patterned route can spark curiosity — keep it subtle, not a scent bomb.
Peak rut (often early to mid-November in much of Wisconsin)
This is when tarsal earns its keep. Pair it with a mock scrape, soft grunt, or light rattling for cruising bucks. Crosswind/upwind placement matters more as bucks move daylight.
Post-rut (late November into early muzzleloader and late seasons)
A few bucks still cruise for remaining does, but pressure is high. Tarsal can still work near leftover scrapes or doe edges — keep it light. Watch local sign (fresh rubs, active scrapes, daylight bucks) more than the calendar alone.
Harvesting tarsal glands from a buck
If you legally harvest a buck and want natural tarsal scent for later sits, treat the glands like any other scent you care about: gloves on, keep them clean, and store them cold.
- Wear disposable gloves. You do not want the musk on your hands, stand clothes, or truck cab.
- Work the hocks, not the whole carcass first. After the deer is tagged and registered per your state rules, locate the dark tufts on the inside of each hind leg.
- Cut the skin patch, not just the hair. Use a sharp knife to take a small square of hide with the tarsal tuft attached. Avoid slicing into the joint mess or dragging the gland through gut pile, blood, or dirt.
- Avoid contamination. Do not set the glands on the ground, in the bed of a dirty truck, or next to your lunch cooler. Keep them away from gas, grease, and food odors.
- Bag and freeze. Double zip-bag each gland (or both together if you will use them as a pair). Squeeze out air, label the date, and freeze. Frozen glands keep usable scent for a season or more for most hunters; if they smell “off” in a rotten way rather than musky when thawed, discard them.
- Thaw only what you need. Pull one gland for a weekend; leave the rest frozen.
Fresh glands can hang for a hunt or two right after the kill if legal and kept off your clothes. For multi-week use, freeze them.
CWD note: Minimize contact with brain, spinal cord, and lymph nodes. Use dedicated knives when you can and clean up afterward (see DNR carcass link below).
Commercial tarsal lures versus natural glands
Natural glands from your own buck smell authentic and cost nothing after the harvest, but they transfer easily to clothes and raise handling and disease-risk questions.
Commercial tarsal/rut lures are convenient; quality varies, and some are urine-based from captive deer.
Fully synthetic / non-urine scents are often the cleaner choice when you want to avoid captive-urine CWD concerns and travel light.
A practical Wisconsin approach: learn scrapes and wind with legal odor-only scents, prefer synthetic when you want fewer urine-source questions, and treat natural glands as optional only where rules clearly allow them. Read the label, then read your state regs.
Setups that actually work
Drag lines
Tie a gland or wick to a short cord and drag from a side approach toward the stand, ending downwind or crosswind of the shot lane — not through your sit. Give the buck a trail to cut without walking into your wind.
Hanging a gland or wick
Hang the gland or a tarsal-soaked wick upwind or crosswind of the stand, about deer-nose height (roughly 2–4 feet), near a scrape or funnel — not on your shooting rail. Let him work the scent in a clear lane, not under your platform.
Mock scrapes
Clear a scrape under an overhanging licking branch, freshen the licking branch, and add a small amount of tarsal scent to the scrape soil or a wick above it. Keep quantities modest. Pair with trails you already believe bucks use.
Rattling and grunts
Tarsal scent alone rarely “calls” a buck from hundreds of yards. Combine it with light rattling or a contact or tending grunt when you see or hear a buck cruising. The scent gives him a reason to close the last stretch once he is already looking for company or a fight.
Wind and hunter scent control
None of this works if your own scent blankets the setup. Play the wind first. Use rubber boots for mock-scrape work when you can, wear gloves handling glands, and store scent gear in its own bag — not in the same tote as your base layers. If the wind is wrong, do not force a tarsal sit just because you thawed a gland.
Mistakes to avoid
- Overdoing it. A little tarsal goes a long way. Flooding a scrape with scent looks unnatural and can bump mature bucks.
- Hanging scent upwind of your body. The deer follows the smell — into your wind cone.
- Handling glands bare-handed then climbing the stand. You become the loudest tarsal source in the woods.
- Using tarsal as a substitute for scouting. Scent will not fix a stand with no travel reason.
- Ignoring season and pressure. Peak-rut tactics on a high-pressure public tract in late season often fail.
- Assuming natural urine products are fine everywhere. Rules differ by state and change; verify before you buy or deploy.
- Moving deer parts carelessly across CWD zones. Glands are deer parts. Follow carcass movement rules.
Legal and CWD note (Wisconsin)
Regulations change. Always confirm current rules before you hunt.
Wisconsin scent rules (current DNR guidance)
According to the Wisconsin DNR deer hunting regulations, scents used only to attract deer by odor may be used for hunting deer statewide, with these limits:
- The scent may not be placed or deposited in a way that makes it accessible for consumption by deer.
- Scents greater than two ounces must be removed daily at the end of shooting hours.
- Scents of two ounces or less do not need to be removed daily and may be placed, used, or deposited in any manner for hunting deer.
Liquid scents are treated differently from bait: Wisconsin’s baiting rules say animal parts and byproducts in bait do not include liquid scents, and processed-container bans for bait do not apply to scent materials. Baiting itself is restricted or banned in many counties for CWD reasons — that is separate from odor-only scent use. Check the DNR baiting map if you also bait.

Wisconsin does not, on that page, impose a statewide “synthetic-only” ban on natural deer urine. Other states and many agencies encourage synthetic or non-urine scents because captive-deer urine can carry CWD risk. In Wisconsin, follow the odor-only and quantity rules above, then make your own natural-vs-synthetic risk call. If a label or local rule is unclear, ask the DNR or a warden — do not guess.
Carcass and deer-part movement
Tarsal glands are deer parts. Wisconsin has CWD-related carcass movement and disposal rules: whole carcasses from CWD-affected areas face transport limits, with exceptions for certain processed meat, quarters without spine, cleaned skulls/antlers, and timely delivery to licensed processors or permitted taxidermists. The DNR recommends landfill disposal of carcass waste when possible.

If you hunt outside Wisconsin: check your own state’s scent, urine, and carcass rules every season. Do not copy another hunter’s truck setup across a state line without reading the regs.
FAQ
Do tarsal glands work on does?
Does investigate scent too, but most hunters use tarsal to influence bucks in the rut. Doe or estrous products are a different tactic with the same legality checks.
Can I use tarsal scent on a trail-cam scrape?
Yes, if legal. Check cameras infrequently — weekly pressure plus fresh scent can push bucks nocturnal.
How long does a frozen gland last?
Often through the next season if kept solidly frozen and double-bagged. Musky/sharp is normal; spoiled-meat rotten means toss it.
Is a mock scrape baiting?
In Wisconsin, odor-only scents under the rules above are not bait piles. Do not add feed or animal-based bait where baiting is restricted. Read the DNR baiting and scent pages together when unsure.
Worried about CWD with natural glands?
Synthetic odor lures avoid captive-urine questions. Either way, follow Wisconsin scent and carcass rules and do not scatter deer parts into new areas.
Bottom line
Tarsal scent is a rut tool, not magic. Pattern deer first, play the wind, keep the dose small, and put scent where a buck can work it without smelling you. In Wisconsin, odor-only scents are legal statewide under DNR quantity and placement rules — re-check those rules each season and verify the state you actually hunt.
