Wire Snare Trapping: Legal Overview, Setup, and Animal Targeting

Wire snares are the most efficient trap per setup minute. A properly placed snare on an active rabbit run takes 5 minutes to install and can catch the animal in its next pass. The challenge is specificity: snares must be positioned precisely for the target species, anchored firmly, and placed on genuinely active runs — a snare 2 inches off the ground on a squirrel run catches nothing. This article covers the setup specifics that produce catches. The full trap comparison is in trapping and snaring: 8 traps that produce consistent small game.

Wire Specifications

Wire gauge determines snare strength, loop-forming ease, and how much resistance the snare presents to a triggering animal. Thinner wire is less visible but breaks under the thrashing of a larger animal; heavier wire is more reliable but harder to form into a tight loop.

• 24-gauge galvanized steel wire (0.51mm diameter): The standard for rabbit. Holds a rabbit without breaking under normal struggling. Forms a loop easily with fingers. A 100-foot spool weighs approximately 150g and produces 24–30 snares (4 feet of wire per snare).
• 28-gauge galvanized wire (0.36mm): For squirrel-sized animals and smaller. Lighter and less visible. Breaks if a rabbit or larger animal is caught.
• 22-gauge galvanized wire (0.64mm): More durable for larger animals; harder to form into a consistent loop. Use for raccoon or medium-sized target species.

Stainless steel wire is superior in wet conditions (doesn’t rust, maintains tension longer) but costs more and is harder to find in hardware stores. Galvanized wire is adequate for short-term trap lines.

Loop Construction

Cut 4 feet of wire per snare. The loop forms from a small fixed eye at one end that the wire slides through (noose knot).

• Step 1 — form the eye: At one end of the wire, make a small loop 1/4 inch in diameter by wrapping the wire end around a nail or pen once and twisting 4–5 times. This eye is the fixed end of the noose.
• Step 2 — thread the noose: Pass the other end of the wire back through the small fixed eye, forming the sliding noose loop.
• Step 3 — size the loop: Adjust the loop to the target diameter before installing (easier to size off the animal’s run than after anchoring). For rabbit: 4-inch diameter loop. For squirrel (ground set): 3-inch diameter loop. For squirrel (pole set): 3 inches, centered on pole.

The snare should close freely when the wire slides through the eye — if it sticks or resists, reform the eye slightly larger. A sticky snare allows the animal to back out after the wire tightens.

Loop Height and Position by Species

Loop height above the ground determines whether the snare catches the neck (effective) or the feet (ineffective). Animals travel with their head at a consistent height above the ground depending on their natural gait and body height.

• Eastern cottontail rabbit: Loop bottom at 4 inches above ground (10cm). Loop diameter: 4 inches (10cm). The rabbit’s head travels at approximately 5–6 inches height in a full run; 4-inch height catches the neck as the animal ducks under the loop bottom edge.
• Snowshoe hare: Loop bottom at 5 inches above ground. Hares run higher than cottontails due to longer legs.
• Gray squirrel (ground set on a run): Loop bottom at 3 inches above ground. Loop diameter: 3 inches.
• Squirrel (pole set): Loop diameter 3 inches, centered in the pole at the midpoint of the pole width. Multiple snares on the same pole work together — use 5–8 snares per pole spaced 6–8 inches apart.


• Muskrat (water set): Loop positioned in the animal’s underwater swim path — just below the water surface, in a run visible as a cleared path in submerged vegetation.

Anchor Method

An unanchored snare produces no catches — the animal drags the snare and escapes or the snare moves in the wind. The anchor must hold the snare position within 1 inch of the target height through wind, rain, and the struggling of a caught animal.

Stake anchor (most reliable): Drive a forked stick or a stake with a notch at the top into the ground 12 inches beside the run. The snare wire wraps around the stake near ground level, and the loop is supported at the correct height by a separate small support stick or the stake itself if the fork is at the right height. The stake must not wobble — drive into firm soil not soft mud.

Vegetation anchor: Tie the snare wire to a flexible green branch at ground level. The loop is supported at the correct height by a thin stick woven through the surrounding vegetation to hold the loop vertical. Disadvantage: vegetation bends in wind, moving the loop. Only use in still air or with thick stem anchors.

Wire support stick: Use a second 6-inch stick pushed into the ground perpendicular to the run to hold the loop upright and at the correct height. This is separate from the anchor — the anchor holds the snare in place, the support stick holds the loop vertical and at the right height. Without a support stick, the loop leans to one side and animals duck past it.

Finding and Using Active Runs

A snare on an inactive run catches nothing. Active rabbit runs show:

• Compressed soil or grass in a consistent path 6–8 inches wide
• Rabbit pellets (small dark spherical droppings) at multiple points along the run
• Gnawed vegetation at the sides of the run — bark, grass tips, or clover stems showing fresh cuts
• Fur caught on vegetation at the sides at rabbit-body height

The highest-percentage placement is where the run passes through a natural chokepoint — between two trees less than 8 inches apart, through a gap in a brush pile, or under a low log. At a chokepoint, the animal has no lateral route to avoid the snare loop. On an open run without a chokepoint, add a guide stick on each side of the run to funnel the animal through the loop center.

Legal Status by State Category

Wire snares are regulated across all North American jurisdictions. Summary by category:

• License required, snares permitted with restrictions: Most eastern US states (Maine, Vermont, New Hampshire, New York, Pennsylvania, and others) allow wire snares under a trapping license with restrictions on diameter, check frequency, and seasonal dates.
• Snares heavily restricted or banned: California, Oregon, Colorado, and Washington have significant snaring restrictions to protect non-target wildlife. Foothold snares specifically are prohibited in several states.
• Canadian provinces: All provinces require a trapping license; regulations vary significantly by species and region. Check the provincial wildlife authority.
• Survival necessity doctrine: In a documented wilderness survival emergency (lost, injured, communications failed), taking wildlife by any available means is legally defensible under necessity doctrine in most jurisdictions. This is a common-law defense, not an explicit license exemption — verify with an attorney for your jurisdiction.
