Nuisance Wildlife Control Operator Trapping and Capture Methods 1 Flashcards

When using a body-gripping (Conibear-style) trap in a culvert or drainpipe for muskrat, what is the correct jaw spread size to use?

Answer: #110 (4.5-inch jaw spread)

A #110 body-gripping trap with a 4.5-inch jaw spread is sized appropriately for muskrats and fits snugly in small culverts, ensuring quick, humane dispatch without allowing the animal to pass through or escape.

Which type of foothold trap modification is most commonly required by state regulations to reduce injury to non-target animals?

Answer: Offset or laminated jaws

Offset or laminated (double) jaws create a small gap when closed, reducing tissue trauma and bone injury to captured animals. Most state regulations mandate this modification to improve animal welfare outcomes for foothold traps.

What is the recommended method for securing a live cage trap to prevent a captured coyote from dragging it away?

Answer: Stake the trap to the ground through the floor frame using a ground anchor or rebar

Staking the trap frame to the ground with rebar or a dedicated ground anchor prevents a strong animal like a coyote from moving or flipping the trap, reducing injury risk and ensuring the animal is present at the next trap check.

When trapping beaver at a dam site using a foothold trap, where is the most effective trap placement?

Answer: In a run or slide at the water's edge, 2–4 inches below the surface

Beaver use consistent runs and slides along the bank at the water's edge. Setting a foothold trap 2–4 inches below the waterline in these travel paths intercepts the beaver naturally and the drowning setup ensures a quick, humane kill.

Which trapping technique is most appropriate when targeting a single 'problem' individual skunk that is denning under a structure?

Answer: Place a box-style live trap directly over or at the den entrance with the door facing out

Placing a box trap at the den entrance intercepts the animal as it exits, targeting the specific individual responsible. This method avoids attracting non-target animals and reduces spray risk by keeping the skunk calm and contained in a dark enclosure.

What is the primary purpose of using a 'stop-loss' device on a foothold trap?

Answer: To prevent a captured animal from twisting off or pulling free of the trap

A stop-loss device — typically a loop of wire or a secondary catch mechanism attached near the foot — prevents a captured animal from wrenching or chewing its limb free ('wring-off'), ensuring the animal is held securely until the operator checks the trap.
