1. What is the primary purpose of fumigation in pest control?
A. To repel pests from entering a structure
B. To kill pests in all life stages in enclosed spaces
C. To trap pests using bait stations
D. To sterilize soil only
Answer: B. To kill pests in all life stages in enclosed spaces
Rationale: Fumigation uses gaseous pesticides to penetrate materials
and eliminate pests at all life stages in sealed environments.
2. Which type of pest is most commonly controlled using fumigation?
A. Birds
B. Termites in open soil
C. Stored product pests
, D. Outdoor weeds
Answer: C. Stored product pests
Rationale: Fumigation is highly effective against insects in stored
grains and sealed commodities.
3. What is the most important requirement before fumigation begins?
A. Applying residual spray
B. Sealing the structure properly
C. Increasing ventilation
D. Adding water to soil
Answer: B. Sealing the structure properly
Rationale: A gastight seal ensures fumigant concentration is
maintained for effectiveness and safety.
4. Which gas is commonly used in structural fumigation?
A. Oxygen
B. Chlorine
C. Sulfuryl fluoride
D. Carbon dioxide
Answer: C. Sulfuryl fluoride
Rationale: Sulfuryl fluoride is widely used for structural fumigation
due to its effectiveness and penetration ability.
5. What is a fumigant?
A. A solid pesticide applied to soil
B. A gas or vapor that kills pests
, C. A bait used in traps
D. A biological control agent
Answer: B. A gas or vapor that kills pests
Rationale: Fumigants are pesticides in gaseous form designed to
penetrate spaces and kill pests.
6. Why is monitoring gas concentration during fumigation important?
A. To reduce cost
B. To ensure pest attraction
C. To maintain lethal levels
D. To speed up aeration
Answer: C. To maintain lethal levels
Rationale: Monitoring ensures the fumigant remains at effective
concentrations for pest elimination.
7. Which structure is most suitable for fumigation?
A. Open fields
B. Sealed warehouses
C. Outdoor parks
D. Wetlands
Answer: B. Sealed warehouses
Rationale: Fumigation requires enclosed spaces to contain the gas.
8. What is aeration in fumigation?
A. Pest inspection
B. Introducing fumigant
, C. Removing fumigant gas after treatment
D. Sealing cracks
Answer: C. Removing fumigant gas after treatment
Rationale: Aeration removes toxic gases to make the area safe for re-
entry.
9. Which factor most affects fumigant effectiveness?
A. Color of structure
B. Temperature
C. Pest behavior only
D. Soil type
Answer: B. Temperature
Rationale: Higher temperatures generally increase fumigant activity
and penetration.
10. What is a primary hazard of fumigation?
A. Noise pollution
B. Gas toxicity to humans
C. Plant overgrowth
D. Water contamination only
Answer: B. Gas toxicity to humans
Rationale: Fumigants are highly toxic and require strict safety
controls.
11. Who is responsible for fumigation safety compliance?
A. Building owner only
