PRACTICE SET
Structural Pesticide Applicator Certification Exam
Practice Questions
1. A commercial applicator is preparing to treat the perimeter
of a food processing plant for cockroaches. According to
federal FIFRA regulations, if the label instructs to "avoid
application to food-contact surfaces," which of the following
actions is the most compliant and effective strategy?
A. Apply a low-pressure residual spray directly to the prep
counters as long as they are wiped down before morning
shifts.
B. Utilize targeted bait stations and crack-and-crevice gel
applications beneath and behind equipment rather than
broad surface sprays.
C. Apply a space spray or ULV fogging while food processing
operations are actively running to ensure maximal exposure.
D. Use a fan spray pattern along the walls up to a height of
four feet across the entire kitchen prep area.
CORRECT ANSWER: B
RATiONAlE: Crack-and-crevice treatments using target
, baits or gels minimize the risk of pesticide drift or
contamination of food-contact surfaces, fully complying
with restrictive label language while effectively managing
structural pests.
2. An applicator notes that a liquid formulation of an
organophosphate insecticide has a very low flash point. What
specific operational hazard does this present, and what
precaution must be taken during transport?
A. It is highly prone to freezing; it must be kept in a heated
compartment.
B. It is highly flammable; it must be kept away from sparks,
open flames, or high-temperature areas in the service
vehicle.
C. It will rapidly degrade under UV light; it must be stored in
light-proof metal containers.
D. It has a high vapor pressure; the applicator must wear a
full-face respirator while driving.
CORRECT ANSWER: B
RATiONAlE: The flash point is the lowest temperature at
which a liquid gives off enough vapor to ignite. A low flash
point indicates a high fire risk, requiring strict isolation
from heat and ignition sources during storage and transit.
3. During a perimeter inspection of a commercial office
building, you identify subterranean termite mud tubes
extending from the soil up a concrete foundation wall to the
sill plate. Which biological characteristic of subterranean
termites explains their necessity for constructing these
shelter tubes?
A. They require high ambient light levels to navigate toward
, cellulose sources.
B. They are highly susceptible to desiccation and rely on the
tubes to maintain a high-humidity microenvironment.
C. The tubes protect them exclusively from cold
temperatures during seasonal transitions.
D. They use the mud tubes to store excess food resources
outside the central colony nesting site.
CORRECT ANSWER: B
RATiONAlE: Subterranean termites have soft cuticles
that lose moisture rapidly. They build mud tubes out of soil,
saliva, and fecal matter to protect themselves from
predators and to maintain the high humidity required for
their survival when foraging above ground.
4. When calibrating a compressed-air sprayer for a structural
barrier treatment, you find that the sprayer delivers 2 gallons
of water over a 1,000 square foot test area at 40 PSI. If the
label requires a rate of 1 gallon per 1,000 square feet, which
adjustment should you make?
A. Double the concentration of the pesticide concentrate in
the tank mix.
B. Decrease the application speed or walking pace by half.
C. Increase the nozzle orifice size to a higher flow rate tip.
D. Increase your walking speed or decrease the operating
pressure appropriately while maintaining a proper pattern.
CORRECT ANSWER: D
RATiONAlE: To decrease the output per unit area, an
applicator can either increase their walking speed, decrease
, the pressure (within effective pattern limits), or switch to a
nozzle tip with a smaller orifice.
5. A pest control technician responds to a severe German
cockroach (Blattella germanica) infestation in a high-rise
apartment complex. The technician notices that despite
repeated applications of a specific pyrethroid spray over the
last six months, the population is thriving. What
phenomenon is likely occurring, and how should the IPM
plan be modified?
A. Behavioral resistance; the technician should increase the
concentration of the pyrethroid past label limits.
B. Physiological resistance; the technician should switch to
an insecticide with a different mode of action, such as an
insect growth regulator (IGR) or a neonicotinoid bait.
C. Target site insensitivity; the technician must switch to a
different brand name product that utilizes the exact same
active ingredient.
D. Enhanced metabolic degradation; the technician should
switch to a water-soluble dust formulation using the same
chemical class.
CORRECT ANSWER: B
RATiONAlE: German cockroaches are notorious for
developing rapid physiological resistance to overused
insecticide classes. Rotating to a completely different
chemical class or mode of action (such as metabolic poisons
or IGRs) is a fundamental resistance management strategy.
6. Which of the following acute toxicity indicators signifies the
most hazardous pesticide formulation to an applicator via
dermal exposure?
