NWCO Wildlife Control Techniques and Safety 2 — Questions and Answers

Question 1: What is the recommended minimum distance to maintain when approaching a potentially rabid raccoon?

5 feet
10 feet
20 feet (Correct answer)
30 feet

Correct answer: 20 feet

A minimum distance of 20 feet is recommended when approaching a potentially rabid animal to reduce the risk of sudden lunging or aggressive contact.

Rabid animals can exhibit unpredictable aggression, including sudden charges. Wildlife control professionals are trained to maintain at least 20 feet of distance when observing a potentially rabid raccoon. This buffer allows reaction time to retreat or deploy protective equipment. Closer distances of 5 or 10 feet are dangerously close to a lunging animal, while 30 feet may be excessive for effective assessment.

Question 2: Which type of personal protective equipment is MOST critical when handling a bat suspected of carrying rabies?

Steel-toed boots
Thick leather gloves (Correct answer)
Safety goggles
High-visibility vest

Correct answer: Thick leather gloves

Thick leather gloves are the most critical PPE for bat handling because rabies transmission occurs through bites, and bat teeth can penetrate thin materials.

Rabies is transmitted through saliva, typically via bites. Bats have very small, sharp teeth that can penetrate thin fabric and rubber gloves without the handler noticing. Thick leather gloves provide the necessary bite resistance. While other PPE items have their uses, preventing a bite wound is the top priority when handling a potentially rabid bat. The CDC specifically recommends leather work gloves for bat capture.

Question 3: When using a catch pole on a medium-sized mammal, where should the loop be positioned?

Around the midsection
Around the neck with one front leg through the loop (Correct answer)
Around both rear legs
Around the base of the tail

Correct answer: Around the neck with one front leg through the loop

The safest catch pole technique places the loop around the neck with one front leg included, distributing pressure and preventing choking or cervical injury.

Professional wildlife control operators are trained to position a catch pole loop around the animal's neck and one front leg. This technique distributes the restraining force across the shoulder and neck area rather than concentrating it on the trachea alone. A loop around only the neck can cause asphyxiation or cervical spine damage. Loops around the midsection provide poor control, and tail or rear-leg loops can cause fractures or allow the animal to twist free.

Question 4: What is the primary safety concern when using chemical repellents containing naphthalene in an enclosed attic space?

Flammability risk
Toxic vapor inhalation by the operator (Correct answer)
Corrosion of electrical wiring
Staining of insulation materials

Correct answer: Toxic vapor inhalation by the operator

Naphthalene produces toxic vapors that concentrate in enclosed spaces, posing serious inhalation risks to operators working in attics without proper respiratory protection.

Naphthalene, the active ingredient in mothballs sometimes used as wildlife repellent, sublimes into vapor that accumulates in enclosed spaces like attics. In high concentrations, naphthalene vapor causes headaches, nausea, hemolytic anemia, and potential liver damage. Operators must use appropriate respiratory protection when working with naphthalene in confined areas. While flammability is a secondary concern, the immediate health risk from inhalation is the primary safety issue.

Question 5: During a skunk removal operation, which approach minimizes the probability of the animal spraying?

Rapid capture with a net from behind
Slow, steady approach with a covered trap (Correct answer)
Using bright flashlights to disorient the animal
Making loud noises to drive it toward an exit

Correct answer: Slow, steady approach with a covered trap

A slow, steady approach with a covered trap reduces visual stimuli and stress, which are the primary triggers for a skunk's defensive spray response.

Skunks give warning signs before spraying: stamping feet, raising the tail, and turning their rear toward the threat. These behaviors are triggered by sudden movements, loud noises, and perceived threats. A slow, calm approach with a dark-covered trap minimizes visual stimulation and stress. The cover prevents the skunk from seeing the operator, reducing the perceived threat level. Rapid movements, bright lights, and loud noises all increase stress and dramatically raise the probability of a spray event.

Question 6: What should an NWCO operator do FIRST upon discovering a dead animal in a client's crawl space?

Immediately remove the carcass with bare hands for speed
Assess for signs of disease and don appropriate PPE before handling (Correct answer)
Spray the area with bleach solution and leave
Call animal control to handle the removal

Correct answer: Assess for signs of disease and don appropriate PPE before handling

Assessing the carcass for disease indicators and donning appropriate PPE before any handling is the correct first step to protect the operator from zoonotic pathogens.

Standard operating procedure for dead animal removal requires a visual assessment first: checking for signs of disease, decomposition stage, and potential hazards. The operator then selects appropriate PPE including gloves, respiratory protection, and potentially a Tyvek suit depending on conditions. Never handle a carcass without PPE regardless of time pressure. The carcass should be double-bagged, the area disinfected, and proper disposal arranged according to local regulations.
