, Question 1
A commercial applicator is treating a food-handling establishment for German
cockroaches. The label for a gel bait specifies a maximum of 4 placements per
linear foot along cracks and crevices. If the treatment area has 120 linear feet of
crack and crevice, what is the maximum number of bait placements allowed?
A. 120
B. 240
C. 360
D. 480
Correct Answer: D - 480
RATIONALE
The label allows 4 placements per linear foot. Multiply 4
placements/ft × 120 ft = 480 placements. Options A, B, and C
represent miscalculations (1, 2, or 3 placements per foot, respectively).
Question 2
Which of the following statements best describes the concept of 'pesticide
resistance management' in the context of general pest control?
A. Rotating pesticides with different modes of action reduces selection
pressure for resistant individuals.
B. Using the same pesticide continuously ensures pests do not develop
resistance.
C. Increasing application frequency prevents resistance by killing all
pests before they reproduce.
D. Resistance is only a concern for agricultural pests, not structural pests.
Correct Answer: A - Rotating pesticides with different modes of
action reduces selection pressure for resistant individuals.
Page 2
, RATIONALE
Rotating modes of action reduces the chance that resistant individuals
survive and reproduce. Continuous use of a single pesticide (B)
accelerates resistance. Increasing frequency (C) can also select for
resistance and is not a management strategy. Resistance occurs in
structural pests (D), so it is a concern.
Question 3
During an inspection of a warehouse, you find rodent droppings and gnaw
marks on packaged goods. Which rodent species is most likely responsible if
the droppings are approximately 1/4 inch long, spindle-shaped, and you
observe burrows along the foundation?
A. House mouse
B. Norway rat
C. Roof rat
D. Deer mouse
Correct Answer: B - Norway rat
RATIONALE
Norway rats produce droppings about 1/4 inch long, are burrowers,
and often infest ground levels. House mouse droppings are smaller
(1/8 inch) and roof rats typically produce similar-sized droppings but
are climbers, not burrowers. Deer mice are not common in warehouses
and have different droppings.
Question 4
Which of the following is a key difference between a residual insecticide and a
non-residual insecticide?
A. Residual insecticides break down quickly and require frequent
reapplication.
B. Non-residual insecticides leave a long-lasting deposit that controls
pests for weeks.
Page 3
, C. Residual insecticides remain active on surfaces for an extended period,
while non-residuals degrade rapidly.
D. Non-residual insecticides are only used outdoors, while residuals are
for indoor use.
Correct Answer: C - Residual insecticides remain active on
surfaces for an extended period, while non-residuals degrade
rapidly.
RATIONALE
Residual insecticides persist on surfaces, providing long-term control;
non-residuals degrade quickly and are often used for immediate
knockdown. Options A and B reverse the definitions. Option D is
incorrect because both types can be used in various settings.
Question 5
An applicator is using a ULV (ultra-low volume) fogger to control flies in a
food processing plant. Which factor is most critical to ensure effective and safe
application?
A. The fogger should be operated at the highest possible flow rate to
maximize coverage.
B. The particle size must be optimized to remain airborne long enough to
contact flying insects.
C. The application should be done during peak production hours to target
active flies.
D. The pesticide should be mixed with water to increase volume and
visibility.
Correct Answer: B - The particle size must be optimized to
remain airborne long enough to contact flying insects.
