Material, Practice Questions & Professional Reference for
Pest Control Technicians
Question 1: Which of the following is the PRIMARY purpose of implementing an Integrated
Pest Management (IPM) program in a commercial food facility?
A. To eliminate all pests using the strongest available pesticides
B. To reduce pest populations to acceptable levels using the least hazardous methods first
C. To apply pesticides on a fixed calendar schedule regardless of pest presence
D. To rely exclusively on biological control agents for long-term pest suppression
CORRECT ANSWER: B. To reduce pest populations to acceptable levels using the least
hazardous methods first
Rationale: Integrated Pest Management emphasizes a systematic approach that prioritizes
prevention, monitoring, and the use of least-toxic control methods before considering chemical
interventions. The goal is not total eradication but maintaining pest populations below
economically or health-damaging thresholds while minimizing risks to humans, non-target
organisms, and the environment.
Question 2: When calibrating a backpack sprayer for a perimeter treatment, which factor is
MOST critical to ensure accurate pesticide application?
A. The color of the spray tank
B. The walking speed of the applicator and nozzle output rate
C. The brand of pesticide being used
D. The time of day the application occurs
CORRECT ANSWER: B. The walking speed of the applicator and nozzle output rate
Rationale: Accurate calibration depends on determining the application rate (gallons per 1,000
sq ft), which is directly influenced by the applicator's walking speed and the nozzle's flow rate.
Incorrect speed or output leads to under- or over-application, compromising efficacy and
potentially violating label requirements or environmental regulations.
Question 3: Which rodent species is characterized by a scaly tail longer than its head and
body combined, large ears, and a preference for nesting in upper levels of structures?
A. Norway rat (Rattus norvegicus)
B. Roof rat (Rattus rattus)
C. House mouse (Mus musculus)
D. Pack rat (Neotoma spp.)
CORRECT ANSWER: B. Roof rat (Rattus rattus)
Rationale: Roof rats are agile climbers with tails longer than their head-body length, large ears
and eyes, and a strong preference for elevated harborage such as attics, rafters, and trees.
Norway rats are larger, burrow-dwelling rodents with shorter tails, while house mice are
smaller with proportionally smaller ears and tails.
Question 4: According to federal pesticide law in the United States, which document MUST
be provided to customers before applying a restricted-use pesticide in a residential setting?
,A. Material Safety Data Sheet (MSDS)
B. Pesticide Product Label
C. Consumer Information Sheet or state-equivalent notification
D. Application invoice with chemical names
CORRECT ANSWER: C. Consumer Information Sheet or state-equivalent notification
Rationale: Under FIFRA and many state regulations, applicators must provide specific consumer
information before applying restricted-use pesticides in residential areas. This often includes a
state-approved information sheet detailing the pesticide name, active ingredients, potential
hazards, and precautions. While labels and SDS are important, they are not the mandated pre-
application notification document for consumers.
Question 5: What is the PRIMARY mode of action of insect growth regulators (IGRs) such as
methoprene or pyriproxyfen?
A. Disruption of the insect nervous system causing paralysis
B. Inhibition of chitin synthesis or mimicry of juvenile hormone, preventing normal
development
C. Destruction of the insect's digestive tract through enzymatic action
D. Blocking oxygen uptake through the spiracles
CORRECT ANSWER: B. Inhibition of chitin synthesis or mimicry of juvenile hormone,
preventing normal development
Rationale: IGRs interfere with insect metamorphosis and reproduction. Juvenile hormone
analogs (e.g., methoprene) prevent larvae from pupating into adults, while chitin synthesis
inhibitors (e.g., novaluron) disrupt exoskeleton formation during molting. They are species-
specific, low in mammalian toxicity, and valuable in IPM for targeting immature pest stages.
Question 6: In termite control, which method is considered a NON-CHEMICAL exclusion
technique?
A. Soil injection with termiticide
B. Installation of physical stainless steel mesh barriers during construction
C. Baiting systems with cellulose matrices containing insecticides
D. Foam application of fipronil into wall voids
CORRECT ANSWER: B. Installation of physical stainless steel mesh barriers during
construction
Rationale: Physical barriers like stainless steel mesh, sand barriers, or plastic sheets prevent
subterranean termites from accessing structures by exploiting their inability to chew through
specific materials or navigate particle-size barriers. These are non-chemical, long-term
exclusion methods integrated into building design, aligning with IPM principles.
Question 7: Which of the following is a KEY indicator of an active German cockroach
infestation in a kitchen environment?
A. Large, cylindrical fecal pellets scattered on floors
B. Pepper-like specks of feces in cabinet corners and along appliance edges
C. Silken tubes or webs in undisturbed storage areas
D. Mud tubes on foundation walls
,CORRECT ANSWER: B. Pepper-like specks of feces in cabinet corners and along appliance
edges
Rationale: German cockroaches produce small, dark, pepper-like fecal droppings that
accumulate in harborage areas such as cracks, crevices, and under appliances. This is a reliable
sign of active infestation. Large pellets suggest rodent activity; silken webs indicate spiders;
mud tubes are characteristic of subterranean termites.
Question 8: When storing pesticides in a commercial facility, which practice is MOST
important for regulatory compliance and safety?
A. Storing all products alphabetically for easy access
B. Keeping pesticides in their original, labeled containers with secondary containment
C. Transferring concentrates to smaller, unlabeled bottles for field use
D. Storing herbicides adjacent to insecticides to consolidate inventory
CORRECT ANSWER: B. Keeping pesticides in their original, labeled containers with secondary
containment
Rationale: Federal and state regulations require pesticides to remain in original containers with
intact labels to ensure proper identification, usage instructions, and hazard information.
Secondary containment (e.g., spill trays) prevents environmental contamination from leaks.
Repackaging into unlabeled containers violates FIFRA and creates significant safety and liability
risks.
Question 9: Which monitoring tool is MOST effective for detecting low-level activity of stored
product pests in a warehouse?
A. Glue boards placed along baseboards
B. Pheromone-baited sticky traps specific to the target species
C. UV light traps hung near loading docks
D. Bait stations with rodenticide
CORRECT ANSWER: B. Pheromone-baited sticky traps specific to the target species
Rationale: Species-specific pheromone traps attract and capture adult insects (e.g., Indianmeal
moths, cigarette beetles) at very low population densities, enabling early detection and
targeted intervention. General glue boards or UV traps lack specificity and sensitivity for stored
product pests, while rodenticide bait stations target rodents, not insects.
Question 10: What is the PRIMARY reason for rotating pesticide modes of action when
managing pest resistance?
A. To reduce the cost of pesticide purchases over time
B. To delay the development of resistance by reducing selection pressure on any single
biochemical target
C. To comply with aesthetic preferences of clients
D. To simplify record-keeping requirements
CORRECT ANSWER: B. To delay the development of resistance by reducing selection pressure
on any single biochemical target
Rationale: Repeated use of pesticides with the same mode of action selects for resistant
individuals, accelerating resistance evolution. Rotating among chemically unrelated compounds
, with different target sites reduces this selection pressure, preserving the efficacy of available
tools—a cornerstone of resistance management in IPM programs.
Question 11: Which personal protective equipment (PPE) is MINIMALLY required when
applying a pesticide labeled with the signal word "CAUTION" via a handheld sprayer?
A. Full-face respirator, chemical-resistant suit, and gloves
B. Long-sleeved shirt, long pants, shoes, socks, and chemical-resistant gloves
C. Only safety goggles and a dust mask
D. No PPE required if the application is outdoors
CORRECT ANSWER: B. Long-sleeved shirt, long pants, shoes, socks, and chemical-resistant
gloves
Rationale: PPE requirements are dictated by the pesticide label, which is legally enforceable.
For many "CAUTION"-signal-word products applied with handheld equipment, the label
typically mandates basic protective clothing plus chemical-resistant gloves. Signal words
indicate acute toxicity: "DANGER" (highest), "WARNING", then "CAUTION" (lowest), but all
require label-specified PPE.
Question 12: In wildlife management, which technique is considered NON-LETHAL and
preferred for excluding bats from an attic during non-maternity season?
A. Shooting with a .22 caliber rifle
B. Installing one-way exclusion devices over entry points
C. Applying rodenticide bait blocks near roosting sites
D. Sealing all entry points permanently without inspection
CORRECT ANSWER: B. Installing one-way exclusion devices over entry points
Rationale: One-way exclusion devices allow bats to exit but prevent re-entry, humanely evicting
colonies without harm. This must be timed outside maternity seasons (when flightless young
are present) to avoid trapping juveniles. Lethal methods are often illegal for protected species
like bats, and sealing entries without exclusion can trap animals inside, causing odor and
secondary pest issues.
Question 13: Which factor is MOST influential in determining the residual efficacy of a liquid
termiticide applied to soil?
A. The color of the termiticide solution
B. Soil texture, organic matter content, and pH
C. The brand name of the application equipment
D. The time of day the application is performed
CORRECT ANSWER: B. Soil texture, organic matter content, and pH
Rationale: Soil properties significantly affect termiticide adsorption, degradation, and mobility.
Clay soils and high organic matter can bind chemicals, reducing bioavailability; extreme pH can
accelerate chemical breakdown. Understanding site-specific soil characteristics is essential for
predicting treatment longevity and ensuring compliance with label-specified application rates.
Question 14: What is the PRIMARY purpose of conducting a thorough inspection BEFORE
implementing any pest control treatment?
A. To estimate the total cost of chemicals needed
B. To identify the pest species, extent of infestation, conducive conditions, and client concerns
