1. Which of the following is the most important factor to consider
when selecting a pesticide for an indoor ant infestation?
A. Brand popularity
B. Target pest species and pesticide label instructions
C. Color of the pesticide
D. Cost per gallon
Rationale: Correct pesticide selection depends on identifying the
target pest and strictly following the pesticide label instructions, which
is a legal requirement. Brand popularity, color, or cost alone do not
ensure effectiveness or safety.
2. What is the main purpose of using baits instead of sprays for ant
control indoors?
, A. To avoid stains on walls
B. To allow for colony-wide elimination
C. To reduce odor
D. To save money
Rationale: Baits are designed to be taken back to the colony, allowing
for elimination of the queen and other ants. Sprays may only kill
visible ants without affecting the colony.
3. Which of the following PPE (personal protective equipment) is
required when applying a liquid herbicide labeled for foliar
application?
A. Safety glasses only
B. Gloves, long sleeves, and eye protection
C. Respirator only
D. Ear protection
Rationale: The pesticide label specifies required PPE. For foliar
herbicide applications, gloves, long sleeves, and eye protection
prevent chemical exposure to skin and eyes.
4. A homeowner reports seeing mice in their kitchen. Which is the
most effective long-term control method?
A. Spraying insecticide
B. Setting multiple traps and removing food sources
, C. Using ultrasonic repellents
D. Mopping the floor frequently
Rationale: Rodent control requires mechanical removal (traps),
sanitation, and exclusion. Sprays are ineffective on rodents, and
ultrasonic devices have limited scientific support.
5. What is the primary function of an insect growth regulator (IGR)?
A. Kill adult insects immediately
B. Repel insects from treated areas
C. Interfere with insect development and reproduction
D. Mask the presence of pests
Rationale: IGRs disrupt molting, development, or reproduction,
preventing the next generation rather than killing adults instantly.
6. Which of the following is a non-chemical method of termite
control?
A. Soil-applied termiticide
B. Physical barriers such as steel mesh or sand barriers
C. Fumigation
D. Baiting with termiticide
Rationale: Physical barriers are non-chemical methods used during
construction to prevent termite access. Termiticides and fumigation
are chemical controls.
, 7. Why is it important to read the pesticide label before every
application?
A. To check the price
B. Because it is a legal document specifying safe and effective use
C. To find the brand name
D. To compare colors
Rationale: The label is a legal requirement and provides critical
information on dosage, target pests, PPE, application methods, and
restrictions.
8. Which type of insecticide formulation is least likely to cause drift
when applied outdoors?
A. Granules
B. Ultra-low volume (ULV) sprays
C. Mist sprays
D. Aerosols
Rationale: Granular formulations are heavy and fall to the ground,
minimizing drift compared to fine sprays or aerosols.
9. When using a backpack sprayer, what is the primary reason for
maintaining even pressure?
A. To save energy
B. To cover only corners
