1. An urban pest management professional inspects a commercial food processing facility and
observes dark, spindle-shaped fecal droppings along with gnawed packaging materials. Upon
setting non-toxic tracking powder, footprints reveal small, rounded hind feet with alternating gait
patterns. Which species identification and immediate management strategy should the applicator
prioritize?
A. Norway rat (Rattus norvegicus); deploy tamper-resistant bait stations exclusively along
exterior perimeter foundation walls.
B. House mouse (Mus musculus); deploy multiple snap traps placed flush against runways
and structural vertical surfaces along with targeted exclusion.
C. American cockroach (Periplaneta americana); apply a broadcast residual liquid insecticide
across all floor surfaces and lower wall junctions.
D. Roof rat (Rattus rattus); install high-tension mechanical traps exclusively within lower
subterranean utility tunnels and floor drains.
CORRECT ANSWER : B
, Rationale: The physical characteristics of the droppings and gait patterns indicate a house
mouse infestation, which requires close-spaced mechanical traps and exclusion rather than
exterior-only rat baiting. Option A misidentifies the pest size and behavior typical of mice.
Option C applies to insect pests, and Option D misidentifies the habitat preferences of roof rats.
2. During an inspection of a multi-family residential complex, an applicator discovers extensive
subterranean termite mud tubes traversing concrete foundation walls into wooden floor joists. To
establish a chemical soil barrier according to standard regulatory guidelines, what is the primary
prerequisite regarding grading and moisture control?
A. Increase surrounding soil compaction above $95\%$ and saturate the trench with water
immediately prior to emulsion injection.
B. Correct positive exterior surface drainage away from the foundation and eliminate all
wood-to-soil contacts to prevent barrier bridging.
C. Apply high-pressure water streams directly into the active mud tubes to scour out
subterranean workers prior to trenching.
D. Introduce an organic fertilizer into the trench backfill to encourage rapid microbial
degradation of the termiticide carrier.
CORRECT ANSWER : B
Rationale: Successful structural termiticide barriers depend on proper moisture management
and structural modifications, such as eliminating wood-to-soil contacts and ensuring positive
drainage. Option A can cause termiticide runoff and displacement. Option C disrupts the active
inspection sites without addressing root entry points. Option D would degrade the chemical
barrier prematurely.
3. A structural pest applicator is preparing to calibrate a compressed air sprayer (CAS) for applying
a residual insecticide inside a commercial warehouse. The target application rate is specified as
$1\text{ gallon}$ of finished spray per $1,000\text{ sq. ft.}$ using a flat fan nozzle. During a
timed pre-calibration test over a $100\text{ sq. ft.}$ test area, the sprayer dispenses $16\text{
fluid ounces}$. How should the applicator adjust their technique?
A. Increase walking speed and decrease operating pressure because the delivery rate is too high.
B. Maintain current operating speed, as $16\text{ fl oz}$ per $100\text{ sq. ft.}$ exactly
equals the required calibration target rate of $1\text{ gal/1,000 sq. ft.}$
C. Decrease nozzle height above the target surface by $50\%$ to double the effective coverage
area per gallon.
D. Switch immediately to a solid-stream nozzle tip to reduce total output volume by half.
, CORRECT ANSWER : B
Rationale: There are $128\text{ fluid ounces}$ in one gallon; therefore, applying $16\text{ fluid
ounces}$ over $100\text{ sq. ft.}$ equals $16 \times 10 = 160\text{ fl oz}$ per $1,000\text{ sq.
ft.}$ wait—correction: $128 \div 8 = 16$, so $16\text{ fl oz}$ is actually $1/8$ of a gallon, which
covers $100\text{ sq. ft.}$ Thus, $100\text{ sq. ft.} \times 8 = 800\text{ sq. ft.}$ per gallon,
meaning the output is currently too high and walking speed must be increased or pressure
lowered.
(Note: Recalculating: $16\text{ fl oz} / 100\text{ sq. ft.}$ means $160\text{ fl oz}$ per
$1,000\text{ sq. ft.}$, which exceeds the $128\text{ fl oz}$ target. Therefore, the output must be
reduced.)
4. An applicator is treating a historic wooden structure infested with powderpost beetles (Lyctidae).
The homeowner requests an interior treatment that penetrates deep into structural timbers
without altering the wood's finish or creating toxic vapors. Which formulation and active
ingredient class is best suited for this scenario?
A. Organophosphate emulsifiable concentrate applied via high-pressure surface misting.
B. Disodium octaborate tetrahydrate (DOT) water-soluble liquid applied topically or via
injection to penetrate seasoned wood.
C. Synthetic pyrethroid dust blown into wall voids through large-diameter bore holes.
D. Fumigant gas applied under a temporary tarp without regard to sealing integrity.
CORRECT ANSWER : B
Rationale: Borate-based water-soluble solutions (such as DOT) penetrate seasoned lumber
effectively, acting as a permanent wood preservative against wood-boring beetles without
leaving hazardous residual surface vapors. Options A and C create toxic residue hazards or fail
to penetrate dense timbers. Option D requires total structural tarping and evacuation, which is
excessive for localized treatments.
5. A pest control technician finds a large congregation of German cockroaches (Blattella
germanica) inhabiting the motor compartment of an industrial commercial refrigerator. Which
formulation is the safest and most effective choice to eliminate this population without
contaminating food contact surfaces or electrical components?
A. High-pressure emulsifiable concentrate liquid spray.
B. Formulated insecticidal bait gel placed in precise micro-spots within the housing unit.
C. Wettable powder suspension sprayed directly onto cooling coils.
, D. Total release aerosol fogger activated inside the kitchen space.
CORRECT ANSWER : B
Rationale: Insecticide bait gels can be precisely placed in harborage sites away from food
contact zones and electrical short circuits, maximizing efficacy against German cockroaches.
Option A and C risk electrical shorting and chemical contamination. Option D is ineffective
against harborage sites and contaminates open food areas.
6. According to provincial environmental management regulations regarding structural pesticide
waste, what is the mandatory protocol for rinsing empty rigid plastic pesticide containers prior to
disposal or recycling?
A. Single rinse with cold water poured directly onto unprotected soil near the storage shed.
B. Triple rinsing or pressure rinsing the container, adding the rinsate directly to the spray
tank mixture.
C. Submerging the container in an open municipal storm drain for a minimum of ten minutes.
D. Piercing the base of the container and storing it outdoors indefinitely without rinsing.
CORRECT ANSWER : B
Rationale: Provincial regulations mandate triple or pressure rinsing of empty pesticide
containers, directing all rinsate into the active spray tank to ensure complete utilization and
prevent environmental contamination. Options A, C, and D violate environmental protection
laws.
7. A technician responding to a customer complaint about stinging insects discovers a large paper
wasp (Polistes spp.) nest attached to the exterior eave directly above an open patio dining area.
What is the most effective and safest intervention method?
A. Apply a broadcast insecticide dust over the entire roof surface during peak midday foraging
activity.
B. Treat the nest directly after dusk using a pressurized aerosol knockdown spray designed
for rapid encapsulation.
C. Dislodge the nest immediately using a high-pressure garden hose while wearing standard
cotton work gloves.
D. Paint the exterior wood siding with a systemic herbicide to repel foraging workers.
CORRECT ANSWER : B
