Nuisance Wildlife Control Operator Certification Exam — Questions and Answers

Question 1: What ESA protection applies to bat species that affects NWCO operations?

Only fruit bats are protected
No bat species are federally protected
Several species including Indiana bat and northern long-eared bat are federally listed, restricting exclusion activities (Correct answer)
Bats are protected only in national parks

Correct answer: Several species including Indiana bat and northern long-eared bat are federally listed, restricting exclusion activities

Multiple federally listed bat species impose significant restrictions on exclusion timing, methods, and require agency consultations.

Question 2: Small, cone-shaped excavations roughly 3 to 4 inches wide and 2 to 3 inches deep are scattered across a lawn with virtually no displaced soil mound near the holes. This foraging sign is most characteristic of which animal?

Groundhog
Eastern mole
Skunk (Correct answer)
Armadillo

Correct answer: Skunk

Skunks dig neat, inverted-cone-shaped holes when rooting for grubs and beetle larvae just below the turf surface; unlike moles they do not create soil ridges, and unlike groundhogs they leave no large mound because they scatter small amounts of soil as they work.

Question 3: During a wildlife damage inspection, an operator finds gnaw marks on electrical wiring in an attic. What immediate safety action is required?

Set snap traps near the damaged wiring
Cover the exposed wires with duct tape
Recommend the client contact a licensed electrician before proceeding with wildlife work (Correct answer)
Continue the inspection since the wiring appears intact

Correct answer: Recommend the client contact a licensed electrician before proceeding with wildlife work

Damaged electrical wiring creates fire and electrocution hazards that must be addressed by a licensed electrician before wildlife control work continues.

Question 4: A client reports a raccoon in their attic that has caused significant damage to insulation and wiring. According to most state regulations, which of the following actions is a licensed NWCO generally permitted to take with this nuisance animal?

Trap and euthanize the animal or relocate it according to state and local guidelines. (Correct answer)
Live-trap the animal and release it on-site after sealing entry points.
Relocate the raccoon to a national forest several counties away.
Sell the captured raccoon to a licensed fur dealer.

Correct answer: Trap and euthanize the animal or relocate it according to state and local guidelines.

State laws typically authorize licensed NWCOs to take, transport, and either release or euthanize specific nuisance wildlife causing property damage. However, there are strict rules. Selling nuisance wildlife is generally prohibited, except for certain species like coyotes or beavers in some states, and often only during a legal trapping season. Relocation is also highly regulated, often restricted to the same county or an adjacent one, and requires landowner permission for the release site. On-site release is sometimes an option, but trapping followed by humane euthanasia or relocation per specific guidelines is the most broadly correct and legal course of action.

Question 5: Which fumigant is commonly used for burrowing rodent control and requires a restricted-use license?

Aluminum phosphide (Correct answer)
Methane
Nitrogen
Carbon dioxide

Correct answer: Aluminum phosphide

Aluminum phosphide produces phosphine gas when contacting moisture and is the most commonly used restricted-use fumigant for burrowing rodent control.

Question 6: What stress-reduction practice should operators follow when transporting captured wildlife?

Keep windows open for fresh air
Cover the trap with a dark cloth to reduce visual stimulation (Correct answer)
Play music to calm the animals
Transport multiple species together

Correct answer: Cover the trap with a dark cloth to reduce visual stimulation

Covering traps with dark material reduces visual stimulation, significantly decreasing stress and defensive behaviors.

Question 7: During which months should operators avoid raccoon exclusion from attics in the eastern US?

March through June (Correct answer)
July-August
October-November
January-February

Correct answer: March through June

March through June is raccoon birthing and nursing season when non-mobile young are present in attic dens.

Question 8: A NWCO is hired to remove a flock of Canada geese from a corporate campus where they have become aggressive towards employees. The geese have several active nests with eggs. Under the Migratory Bird Treaty Act (MBTA), what is the correct first step the NWCO or landowner must take?

Use pyrotechnics and dogs to haze the geese away from the property.
Destroy the nests and eggs immediately to encourage the geese to leave.
Capture and relocate the adult geese to a nearby state park.
Apply for a federal depredation permit from the U.S. Fish and Wildlife Service. (Correct answer)

Correct answer: Apply for a federal depredation permit from the U.S. Fish and Wildlife Service.

The Migratory Bird Treaty Act (MBTA) protects nearly all native bird species, including their nests and eggs. To legally take, capture, or kill a migratory bird, or to disturb an active nest, a federal depredation permit is required. The U.S. Fish and Wildlife Service issues these permits for situations where birds are causing property damage or are a threat to public health. While hazing is a non-lethal option, disturbing birds on an active nest to the point of abandonment can be considered a violation, and a permit is the required first step for nest and egg removal.

Question 9: A client reports hearing "chattering, scampering, and the sound of nuts rolling" coming from their attic, primarily during the daytime and especially in the early morning. Which of the following mammals is the most likely culprit?

Norway rats
An opossum
Gray squirrels (Correct answer)
Little brown bats

Correct answer: Gray squirrels

Gray squirrels are diurnal, meaning they are active during the day. [1, 3] The sounds described—scampering, chattering vocalizations, and the rolling of stored nuts—are all highly characteristic of squirrel activity in an attic. [8] Rats, bats, and opossums are primarily nocturnal.

Question 10: Multiple young orchard trees show a ring of gnawed bark removed from the lower 6 inches of their trunks during winter, with narrow incisor marks approximately 3 mm wide and the damage hidden beneath snow level. The most probable cause is:

Porcupine feeding on cambium
Cottontail rabbit girdling
Meadow vole girdling (Correct answer)
White-tailed deer browsing

Correct answer: Meadow vole girdling

Meadow voles travel beneath snow in runways and girdle tree trunks at or just below the snow surface, leaving very narrow tooth marks (about 3 mm) compared to the wider marks of rabbits or the high-elevation damage of porcupines.

Question 11: A client asks an NWCO operator to relocate a trapped coyote to a state park 40 miles away. Which legal concern is most relevant?

Many states prohibit relocation of coyotes and require euthanasia as the only legal disposition (Correct answer)
The Lacey Act prohibits any interstate movement of coyotes without a federal permit
Coyotes are protected under the Migratory Bird Treaty Act, making relocation illegal
Relocation is always permitted as long as the release site is on public land

Correct answer: Many states prohibit relocation of coyotes and require euthanasia as the only legal disposition

Most states classify coyotes as unprotected or nuisance species and explicitly prohibit relocation due to disease transmission risks (e.g., rabies, mange) and ecological concerns. Operators must follow state-specific disposition rules, which often mandate euthanasia.

Question 12: According to regulations, traps used by Nuisance Wildlife Control Operators should be:

Tagged, or labeled with the permit number, or trapper I.D. number. (Correct answer)
Cleaned regularly to maintain hygiene standards.
Only set during daylight hours.
Marked with the operator's contact information.

Correct answer: Tagged, or labeled with the permit number, or trapper I.D. number.

Explanation: <br> Nuisance Wildlife Control Operators are required to ensure that traps used for capturing wildlife are tagged or labeled with specific identification information. This includes the permit number or trapper identification number, which helps in identifying the responsible operator and ensures compliance with regulatory requirements. Proper labeling or tagging of traps is essential for accountability and effective management of wildlife control activities.

Question 13: Which disease from bird droppings poses the greatest respiratory health risk when cleaning a large pigeon roost?

Salmonellosis
Histoplasmosis (Correct answer)
Avian influenza
West Nile virus

Correct answer: Histoplasmosis

Histoplasmosis, caused by Histoplasma capsulatum that grows in bird droppings, poses the greatest respiratory risk when dried droppings are disturbed.

Question 14: Which federal law provides the broadest protection for native bird species?

Bald and Golden Eagle Protection Act
Lacey Act
Endangered Species Act
Migratory Bird Treaty Act (Correct answer)

Correct answer: Migratory Bird Treaty Act

The MBTA protects over 1,000 native bird species regardless of conservation status.

Question 15: When a captured animal shows open-mouth breathing, lateral recumbency, and unresponsiveness to a light touch, what is the most appropriate immediate action for the operator?

Begin transport to a licensed rehabilitator immediately
Administer oral fluids and monitor for 30 minutes
Release the animal on-site to reduce stress
Assess whether emergency euthanasia is warranted to prevent prolonged suffering (Correct answer)

Correct answer: Assess whether emergency euthanasia is warranted to prevent prolonged suffering

Open-mouth breathing, lateral recumbency, and unresponsiveness are signs of severe physiological stress or capture myopathy that may be fatal. The humane standard requires the operator to assess whether immediate euthanasia is necessary to prevent prolonged suffering, rather than initiating transport that could worsen the animal's condition.

Question 16: Which sign BEST indicates flying squirrel infestation rather than gray squirrel in an attic?

Entry holes larger than 3 inches in diameter
Daytime vocalizations from the attic
Nighttime scratching and running sounds (Correct answer)
Large gnaw marks on wooden beams

Correct answer: Nighttime scratching and running sounds

Flying squirrels are nocturnal, so nighttime activity sounds are the key distinguishing indicator compared to diurnal gray squirrels.

Question 17: A homeowner reports numerous small to medium-sized, irregularly shaped holes drilled into their cedar siding, some arranged in horizontal or vertical lines. What is the most likely cause of this damage?

Bat
Flying squirrel
Carpenter bee
Woodpecker (Correct answer)

Correct answer: Woodpecker

Woodpeckers create holes in wooden structures for foraging, nesting, or drumming. The pattern of multiple, sometimes linear, drilled holes is characteristic of their foraging behavior. Carpenter bees create perfectly round holes. Squirrels gnaw larger, rougher entry points, and bats do not create holes.

Question 18: Which statement about ultrasonic repellent devices is MOST accurate in the context of IPM?

They are the most effective non-lethal wildlife deterrent available
They permanently displace wildlife from treated areas
They are required by law before any trapping is permitted
Scientific evidence for their effectiveness against most nuisance wildlife is limited and they are not a reliable primary tool (Correct answer)

Correct answer: Scientific evidence for their effectiveness against most nuisance wildlife is limited and they are not a reliable primary tool

Research has consistently shown that ultrasonic devices have limited and short-lived effectiveness against most wildlife species and should not be relied upon as a primary IPM strategy.

Question 19: Five-toed hind foot prints approximately 3 inches long resembling a small human hand in mud indicate which species?

Raccoon (Correct answer)
Domestic cat
Beaver
Opossum

Correct answer: Raccoon

Raccoon hind foot prints are distinctive for their elongated, 5-toed pattern resembling a miniature human hand print.

Question 20: A NWCO is working in a wet, marshy area and has a small, open cut on their hand. This environment is frequented by raccoons, muskrats, and rats. Contact with water contaminated by the urine of these animals could lead to which bacterial disease?

Histoplasmosis
Leptospirosis (Correct answer)
Baylisascariasis
Lyme Disease

Correct answer: Leptospirosis

Leptospirosis is a bacterial disease spread through the urine of infected animals, which can contaminate water and soil. The bacteria can enter the body through cuts in the skin or through mucous membranes (eyes, nose, mouth). NWCOs working in wet environments are at an increased risk.

Question 21: What anatomical feature makes North American porcupines unique among rodents?

A prehensile tail
Webbed feet
Bioluminescent markings
Modified hairs (quills) covering the dorsal surface and tail (Correct answer)

Correct answer: Modified hairs (quills) covering the dorsal surface and tail

The porcupine's approximately 30,000 barbed quills are unique among North American rodents.

Question 22: What must an NWCO operator record when applying a restricted-use pesticide?

Product name, EPA registration number, amount applied, location, date, target pest, and applicator certification number (Correct answer)
No records are required
Just the client's name and address
Only the product name and date

Correct answer: Product name, EPA registration number, amount applied, location, date, target pest, and applicator certification number

Comprehensive application records are required for restricted-use pesticides including product details, quantities, location, and applicator information.

Question 23: Which element is MOST important to include in a wildlife service contract?

A list of all wildlife species in the US
Guarantee terms and exclusions (Correct answer)
The client's social security number
The operator's personal home address

Correct answer: Guarantee terms and exclusions

Clearly stated guarantee terms and exclusions prevent disputes by defining what work is covered and for how long.

Question 24: What is the primary characteristic for differentiating red foxes from gray foxes in the field?

They cannot be differentiated
Red foxes are always completely red
Red foxes have white-tipped tails; gray foxes have black-tipped tails with a black dorsal stripe (Correct answer)
Gray foxes are always larger

Correct answer: Red foxes have white-tipped tails; gray foxes have black-tipped tails with a black dorsal stripe

Tail tip color is the most reliable field mark regardless of body color variations.

Question 25: What is the primary purpose of using a 'stop-loss' device on a foothold trap?

To anchor the bait securely inside the trap pan
To prevent the trap from triggering on very light animals
To prevent a captured animal from twisting off or pulling free of the trap (Correct answer)
To slow the closing speed of the jaws for a more humane catch

Correct 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.

Question 26: When setting a price for wildlife control services, which factor is LEAST relevant?

The color of the homeowner's house (Correct answer)
Cost of materials and equipment
Local market rates and overhead costs
Labor and time required

Correct answer: The color of the homeowner's house

Pricing should be based on business costs, labor, materials, and market rates — aesthetic features of the property have no bearing on service pricing.

Question 27: Which step is FIRST in the IPM hierarchy for nuisance wildlife management?

Immediate lethal removal of all animals present
Application of chemical repellents across the property
Installation of ultrasonic deterrent devices
Prevention and habitat modification to make the site less attractive to wildlife (Correct answer)

Correct answer: Prevention and habitat modification to make the site less attractive to wildlife

IPM starts with the least invasive and most sustainable approach — preventing access and reducing attractants before considering removal.

Question 28: A NWCO traps a raccoon in a cage trap on a hot, sunny day. The operator cannot immediately transport the animal for dispatch or release. Which of the following actions is most critical for the humane handling and temporary care of the animal?

Leaving the trap completely uncovered so the animal can see its surroundings.
Covering a portion of the trap to provide shade and a sense of security. (Correct answer)
Attempting to handle the animal to calm it down.
Providing the animal with a large meal.

Correct answer: Covering a portion of the trap to provide shade and a sense of security.

Covering part of the trap is essential to protect the animal from hyperthermia (heat stress) from direct sun and reduces visual stimuli, which helps to lower its stress and fear.

Question 29: When documenting a nuisance wildlife inspection, which detail is LEAST important to record?

Location and size of entry points
Date and time of inspection
Species confirmed or suspected
The homeowner's neighbor's contact info (Correct answer)

Correct answer: The homeowner's neighbor's contact info

While client information is necessary, the neighbor's contact information is not part of the site inspection documentation unless they are also affected.

Question 30: An opossum in a live trap is lying motionless, eyes partially open, tongue extended, and unresponsive to prodding. What is the correct operator response?

Release on-site at once, as thanatosis only occurs in uninjured animals
Administer fluids and transport to a wildlife rehabilitator
Leave the trap covered and undisturbed; the animal will recover within minutes to a few hours (Correct answer)
Euthanize immediately — unresponsiveness indicates severe neurological disease

Correct answer: Leave the trap covered and undisturbed; the animal will recover within minutes to a few hours

Thanatosis ('playing dead') in opossums is an involuntary physiological response, not a sign of injury or disease. Keeping the trap covered reduces stimulation and the animal self-recovers without any intervention.

Question 31: What is the recommended minimum depth for burying a wire mesh barrier to prevent groundhog burrowing under a deck or shed foundation?

24 inches
6 inches
12 inches (Correct answer)
18 inches

Correct answer: 12 inches

A minimum burial depth of 12 inches is recommended for wire mesh barriers targeting groundhogs (woodchucks). Groundhogs rarely dig past 12 inches when they encounter resistance, making this depth effective without requiring excessive excavation.

Question 32: Which field sign most reliably distinguishes meadow vole (Microtus pennsylvanicus) surface damage from Eastern mole (Scalopus aquaticus) tunnel damage in a lawn?

Soft spots in the lawn where subsurface tunnels have collapsed
Visible surface runways with clipped grass blades and droppings along the path (Correct answer)
Volcano-shaped mounds of loose soil with a plugged center hole
Raised, meandering ridges of soil pushed up from below

Correct answer: Visible surface runways with clipped grass blades and droppings along the path

Voles create visible surface runways littered with clipped vegetation and fecal pellets; moles produce raised subsurface ridges and volcano-shaped mounds but do not leave surface runways with clipped grass.

Question 33: What is the maximum legal body-gripping trap size most states allow for raccoon-sized animals on land?

110 (4.5-inch jaw spread)
220 (7-inch jaw spread) (Correct answer)
330 (10-inch jaw spread)
160 (6-inch jaw spread)

Correct answer: 220 (7-inch jaw spread)

The 220 Conibear with 7-inch jaw spread is the standard approved for raccoon-sized animals on land in most jurisdictions.

Question 34: The Migratory Bird Treaty Act (MBTA) provides broad federal protection for most native bird species in the United States. Which of the following groups of birds are famously NOT protected by this act because they are non-native, introduced species?

Rock pigeons, European starlings, and house sparrows. (Correct answer)
Ducks, geese, and swans.
Swallows, swifts, and martins.
Woodpeckers, flickers, and sapsuckers.

Correct answer: Rock pigeons, European starlings, and house sparrows.

The Migratory Bird Treaty Act was established to protect native migratory birds. The rock pigeon (Columba livia), European starling (Sturnus vulgaris), and house sparrow (Passer domesticus) were all introduced to North America from other continents and are legally classified as non-native, invasive species, exempting them from MBTA protection.

Question 35: Which characteristic BEST distinguishes a muskrat lodge from a beaver lodge when observed from a distance in a wetland?

Beaver lodges have multiple above-water entrances while muskrat lodges have only one underwater entrance
Beaver lodges are always situated on dry land adjacent to the water's edge
Muskrat lodges are noticeably smaller and constructed mainly from aquatic vegetation such as cattails and rushes (Correct answer)
Muskrat lodges are built primarily from woody sticks and mud plastered with aquatic debris

Correct answer: Muskrat lodges are noticeably smaller and constructed mainly from aquatic vegetation such as cattails and rushes

Muskrat lodges typically stand only 2–3 feet above the waterline and are composed almost entirely of aquatic vegetation (cattails, bulrushes, sedges). Beaver lodges are substantially larger structures built with branches, sticks, and mud. Size and construction material together are the most reliable at-distance identifiers.

Question 36: A client complains of damage to their lawn consisting primarily of a network of raised ridges of soil that wind across the turf. These ridges are the tops of shallow tunnels. Which animal is the most likely cause?

Norway Rat
Vole
Mole (Correct answer)
Pocket Gopher

Correct answer: Mole

Moles are insectivores that create raised surface tunnels or ridges as they "swim" through the soil searching for earthworms and grubs just below the surface. Voles create surface runways by eating grass but do not push up soil ridges. Pocket gophers create fan-shaped mounds from deeper tunnels, not raised surface ridges. Rats may burrow, but do not create extensive networks of raised turf ridges.

Question 37: Which chimney cap mesh size is considered the industry standard for excluding European starlings while still allowing adequate draft?

3/4-inch galvanized mesh
1/2-inch hardware cloth (Correct answer)
1-inch poultry netting
1/4-inch hardware cloth

Correct answer: 1/2-inch hardware cloth

Half-inch hardware cloth is the standard for chimney cap exclusion targeting starlings. It is small enough to block entry (starlings need roughly 1.5 inches but can probe openings) while maintaining sufficient airflow and resisting corrosion in a flue environment.

Question 38: During which period should bat exclusion work be avoided to prevent trapping flightless young inside a structure?

Late August through September
October through February
March through April
May through mid-August (Correct answer)

Correct answer: May through mid-August

Bat maternity season typically runs from May through mid-August, during which pups are born and cannot yet fly. Performing exclusions during this window traps juveniles inside, leading to die-offs, odor problems, and potential legal violations under state wildlife regulations.

Question 39: What behavioral display MOST reliably distinguishes the spotted skunk from the striped skunk when the animal feels threatened?

The spotted skunk performs a handstand on its front legs with tail raised before releasing its spray (Correct answer)
The spotted skunk sprays without any prior warning display
The striped skunk charges directly toward the threat rather than retreating
The spotted skunk emits a series of loud barking vocalizations before spraying

Correct answer: The spotted skunk performs a handstand on its front legs with tail raised before releasing its spray

Spotted skunks (Spilogale spp.) uniquely perform a handstand — balancing on their front legs with the hindquarters and tail raised toward the threat — before spraying. Striped skunks instead stamp their front feet and arch their back as a warning. The handstand is diagnostic for spotted skunks.

Question 40: What type of wildlife damage is indicated by cone-shaped holes approximately 3 inches in diameter dug throughout a residential lawn?

Squirrel food caching
Groundhog burrow entrances
Skunk foraging for grubs (Correct answer)
Mole tunneling

Correct answer: Skunk foraging for grubs

Skunks create small, cone-shaped holes in lawns when digging for grubs and insects, which is their characteristic foraging pattern.

Question 41: A skunk has taken up residence under a concrete porch, and the homeowner wants it gone. After identifying the main entry point, the NWCO's goal is to allow the skunk to leave on its own before permanently sealing the hole. What is the most appropriate tool for this task?

A one-way excluder door specifically designed for this purpose. (Correct answer)
A sheet of plywood propped against the opening that the skunk can push out.
A large body-gripping trap set within the opening.
A baited cage trap placed directly in front of the opening.

Correct answer: A one-way excluder door specifically designed for this purpose.

A one-way door is an exclusion device that allows an animal to exit a structure but prevents re-entry. This is the ideal tool for humanely removing a denning animal without capture, allowing for the area to be permanently sealed once the animal has departed.

Question 42: A NWCO inspects an attic in early June and confirms a large maternity colony of little brown bats is present. Before installing a one-way excluder device, what is the most critical consideration?

The estimated monetary value of the guano that has accumulated.
The specific type of roofing material on the house.
The exact number of adult bats in the colony to estimate the job's duration.
The presence of non-flying young bats, which would be trapped inside. (Correct answer)

Correct answer: The presence of non-flying young bats, which would be trapped inside.

Performing an exclusion during the maternity season (typically late spring through summer) is improper because it will trap the flightless pups inside the structure. This leads to their death, which is inhumane and can cause significant odor problems. Exclusions must be timed for after the young are able to fly.

Question 43: What is the recommended procedure for an animal captured that appears to have rabies symptoms?

Do not handle directly; contact local animal control or state health department for rabies testing guidance (Correct answer)
Transport to a veterinarian for treatment
Release immediately
Euthanize and dispose in regular trash

Correct answer: Do not handle directly; contact local animal control or state health department for rabies testing guidance

Animals with rabies symptoms should not be handled directly; authorities coordinate rabies testing which requires the intact brain.

Question 44: When should tree branches be trimmed as part of wildlife exclusion?

Only branches touching the roof
Tree trimming is never part of wildlife management
Branches within 6-8 feet of the roof should be trimmed to eliminate wildlife bridge access (Correct answer)
Only during winter

Correct answer: Branches within 6-8 feet of the roof should be trimmed to eliminate wildlife bridge access

Branches within 6-8 feet provide jumping or climbing access for squirrels and raccoons.

Question 45: What is the antidote for anticoagulant rodenticide poisoning in non-target animals?

Calcium gluconate
Vitamin K1 (phytonadione) (Correct answer)
Activated charcoal
Atropine

Correct answer: Vitamin K1 (phytonadione)

Vitamin K1 restores the vitamin K-dependent clotting factor production that anticoagulant rodenticides disrupt.

Question 46: Which statement BEST describes the NWCO's duty when a client requests an illegal method of wildlife removal?

Decline the request and explain which legal alternatives are available (Correct answer)
Contact the client's neighbor for a second opinion
Report the client to federal authorities immediately
Comply if the client signs a waiver

Correct answer: Decline the request and explain which legal alternatives are available

NWCOs are responsible for operating within the law regardless of client requests, and should professionally redirect clients to legal options.

Question 47: What is the primary mechanism of action of second-generation anticoagulant rodenticides like brodifacoum?

Nervous system paralysis
Respiratory failure
Inhibition of vitamin K recycling, preventing blood clotting (Correct answer)
Cardiac arrest

Correct answer: Inhibition of vitamin K recycling, preventing blood clotting

Second-generation anticoagulants inhibit vitamin K epoxide reductase, preventing recycling of vitamin K needed for clotting factor synthesis.

Question 48: A NWCO completes an inspection and determines that the nuisance wildlife problem is caused by an overgrown ivy-covered fence providing cover and a pathway for multiple species. This is an example of identifying:

A structural deficiency
A habitat attractant that requires modification (Correct answer)
A problem outside the NWCO's scope of work
An unenforceable code violation

Correct answer: A habitat attractant that requires modification

Dense vegetation like ivy provides cover, travel corridors, and nesting opportunities that attract and sustain wildlife populations; recommending its removal is part of habitat modification guidance.

Question 49: Clean, 45-degree angled cuts on garden vegetable stems are characteristic of which animal?

Slug or insect damage
Complete plant removal by groundhog
Deer (jagged torn edges)
Rabbit (clean angled cuts from sharp incisors) (Correct answer)

Correct answer: Rabbit (clean angled cuts from sharp incisors)

Rabbits have sharp incisors creating distinctive clean, angled cuts at approximately 45 degrees on plant stems.

Question 50: What is the correct procedure for decontaminating equipment after removing an animal confirmed to have distemper?

No decontamination needed since distemper does not affect humans
Wipe with alcohol-based hand sanitizer
Clean with 10% bleach solution and allow 10 minutes of contact time (Correct answer)
Rinse with plain water and air dry

Correct answer: Clean with 10% bleach solution and allow 10 minutes of contact time

A 10% bleach solution with adequate contact time effectively kills the distemper virus on equipment surfaces, preventing cross-contamination to other animals.

Question 51: What material is MOST resistant to bat entry and recommended for permanently sealing bat exclusion points?

Expanding spray foam
Copper mesh stuffed into gaps and sealed with exterior-grade caulk (Correct answer)
Plastic sheeting
Duct tape

Correct answer: Copper mesh stuffed into gaps and sealed with exterior-grade caulk

Copper mesh sealed with caulk provides durable, corrosion-resistant, and gnaw-proof sealing for bat entry points.

Question 52: While working in a crawlspace with a known raccoon latrine, which piece of Personal Protective Equipment (PPE) is most essential for preventing a potentially severe neurologic disease caused by Baylisascaris procyonis?

A high-visibility safety vest.
Steel-toed boots.
Cut-resistant leather gloves.
An N95-rated or better respirator. (Correct answer)

Correct answer: An N95-rated or better respirator.

*Baylisascaris procyonis*, or raccoon roundworm, produces microscopic eggs in raccoon feces that are extremely durable. The primary risk to humans is the accidental ingestion or inhalation of these eggs. During cleanup, eggs can easily become airborne. An N95-rated respirator is crucial to prevent inhaling these infectious eggs.
