Lures, Baits & Urine

Two trappers set the same dirt-hole on the same field edge. One puts food bait in the hole in September; the other uses a gland lure in late November. Six weeks later, the first trapper wonders why he’s only catching raccoons and skunks. The second has taken three gray fox. The trap type, location, and construction were identical. The attractant made the difference.

The four attractant categories

Predator attractants work on distinct drives. Knowing the drive tells you when and where to use each one.

1. Gland lures Gland lures are formulated from the musk glands, reproductive secretions, or anal sacs of target species. They trigger territorial and breeding instincts. A red fox smelling fox gland lure at your set reads: another fox marked here — what’s the news?

• Season timing: most effective when animals are actively scent-marking, which ramps up through October and peaks in the pre-breeding period (January–February for most SC foxes). Early-September sets benefit less from gland lures.
• Dosage: 2–3 drops at the back of the dirt hole or on a grass stem near the set. More is not better — an overwhelming gland dump reads as alarm, not curiosity.
• Also effective for bobcat: bobcat-specific gland lures or “cat” formulations are available and outperform generic canine lures for cat sets.

2. Food / bait lures Food attractants are extracts of fish oil, beaver castor, anise, cheese, rotten eggs, or other food-scent compounds. They trigger the feeding drive.

• Season timing: best in early season when temperatures are cool enough to prevent rapid spoilage and when animals haven’t yet established heavy territorial scent patterns. In September and October, a food lure at a flat set can draw foxes readily.
• Limitations: food lures are relatively non-selective — they attract raccoons, opossums, and skunks as readily as fox or coyote.
• SC law: no food or meat bait is allowed with bodygrip/Conibear traps. Food bait at a bodygrip set is a legal violation (see the note below).
• Beaver castor is a unique food/gland hybrid that’s highly effective for bobcat sets in addition to beaver trapping.

3. Call lures (curiosity lures) Call lures are blended scents — often combinations of musk, anise, and other compounds — designed to trigger curiosity and investigation without a clear territorial or breeding signal. They’re the “what was that?” trigger.

• Best when you want broad predator appeal with lower species specificity.
• Useful in the first week or two of a season before an area’s territorial patterns are well-established.
• Can be used at the backing of a flat set where you’re not sure whether fox or bobcat is the more likely visitor.

4. Urine Urine from the target species is not a lure by itself — it’s a territorial reinforcement used alongside gland lure. Applied to the backing or nearby grass stem, urine makes the set read like a real scent post, not just a spot with a chemical smell.

• Coyote urine used with coyote gland lure dramatically improves coyote catch rates over gland lure alone.
• Fox urine with fox gland lure does the same for gray and red fox sets.
• Bobcat urine is effective for cat-targeted flat sets.

Matching attractant to target and season

Target	Early season (Sept–Oct)	Mid season (Nov–Dec)	Late season (Jan–Feb)
Gray fox	Food/call lure	Gland + urine	Gland + urine (breeding)
Red fox	Food/call lure	Gland + urine	Gland + urine (breeding)
Bobcat	Curiosity / call lure	Cat gland or beaver castor	Cat gland + urine
Coyote	Food/call lure	Coyote gland + urine	Coyote gland + urine
Beaver	Beaver castor (food/gland)	Beaver castor	Beaver castor

This is a general framework — individual products vary. Read lure manufacturer guidance and adjust based on what you observe catching or passing through your sets.

The why Why does temperature matter for lure effectiveness?

Scent volatilizes faster in warm temperatures and slower in cold. A drop of gland lure in August broadcasts strongly for a few hours and then degrades quickly in the heat; the same drop in January slowly releases over several days. This means warm-weather sets need fresher lure more frequently, and cold-weather sets can go longer between applications. It also means food bait in warm weather spoils fast and creates a repellent rather than an attractant. For SC Piedmont trappers, the early-season heat (September) argues for fresh applications every 2–3 days; mid-winter sets can go a week or more.

Edge case What about commercial versus home-made lures?

Commercial lures from established trapline suppliers (Lenon, Minnesota Trapline Products, Duke’s, etc.) are formulated from real gland/castor materials and are generally more consistent than home blends. If you’re starting out, buy commercial and follow the instructions. Home formulations require access to glands from animals you’ve already caught — a chicken-and-egg problem for beginners. Save homemade lure experimentation for after you’ve built enough of a catch history to compare results.

• ⚠ Safety Confirm: no food/meat bait at any bodygrip/Conibear trap. Verify current SCDNR regulations before each season.
• Match attractant to season: food/call lure early, gland lure mid-to-late, urine supplemental mid-to-late.
• Match to species: fox gland for fox sets, cat gland or beaver castor for bobcat, coyote gland for coyote, beaver castor for beaver.
• Apply 2–3 drops of gland lure only — overdosing repels rather than attracts.
• Lure inside the hole (dirt-hole) or on the backing/object (flat set), NOT on the trap or pan.
• ⚠ Safety Gloves on during all attractant application — human scent on the lure bottle defeats the purpose.
• Re-apply lure after heavy rain or after 5–7 days in warm weather.
