Pest Control Operator Licensing Exam 2025\2026
1. Which is the primary goal of integrated pest management (IPM)?
To minimize the use of chemical pesticides while effectively
controlling pests
Rationale: IPM focuses on combining biological, cultural,
mechanical, and chemical strategies to control pests sustainably.
2. Which of the following is considered a biological control agent?
Ladybugs for aphid control
Rationale: Ladybugs naturally feed on aphids and reduce their
population without chemical intervention.
3. What is the main function of an insect growth regulator (IGR)?
To disrupt the development and reproduction of insects
Rationale: IGRs prevent insects from maturing or reproducing,
reducing future populations.
4. What type of pesticide is applied directly to soil to control
termites?
Soil-applied termiticide
Rationale: Termiticides are applied to soil to create a barrier that
kills or repels termites.
5. Which personal protective equipment (PPE) is essential when
handling concentrated pesticides?
Gloves, goggles, and respirator
Rationale: PPE prevents exposure to harmful chemicals through
skin contact, inhalation, or eye contact.
6. What is the primary vector for Lyme disease?
Blacklegged tick (Ixodes scapularis)
, Rationale: Lyme disease is transmitted primarily through bites of
infected blacklegged ticks.
7. Which method is most effective for preventing rodent infestations
in structures?
Eliminating food, water, and shelter sources
Rationale: Rodent control relies heavily on sanitation and
habitat modification to prevent infestations.
8. Which type of pesticide formulation is generally the least toxic to
humans?
Bait formulations
Rationale: Baits are designed for targeted delivery and reduce
the risk of human exposure compared to sprays.
9. Which pest is commonly associated with stored grains?
Rice weevil
Rationale: Rice weevils infest stored grains and can cause
significant post-harvest losses.
10. What is the main principle behind mechanical pest control?
Using physical barriers or traps to reduce pest populations
Rationale: Mechanical methods prevent pests from accessing
resources or directly remove them.
11. Which insect is considered a primary structural pest in
homes?
Termite
Rationale: Termites feed on wood and can cause significant
structural damage.
12. What is the recommended method for disposing of leftover
pesticides?
Follow local regulations and hazardous waste disposal guidelines
, Rationale: Improper disposal can harm the environment and is
illegal.
13. Which chemical class of insecticides affects the nervous
system by inhibiting acetylcholinesterase?
Organophosphates
Rationale: Organophosphates disrupt nerve function by blocking
acetylcholinesterase, leading to nervous system failure in
insects.
14. Which rodent species is most commonly found in urban
areas?
Norway rat (Rattus norvegicus)
Rationale: Norway rats thrive in sewers and urban environments
where food and shelter are abundant.
15. What is the first step in conducting a pest inspection?
Identify the type of pest and signs of infestation
Rationale: Accurate identification is essential to determine the
most effective control method.
16. Which method is most effective for mosquito control?
Eliminating standing water
Rationale: Mosquitoes breed in stagnant water, so removing
breeding sites reduces populations.
17. Which fungal pathogen is commonly used as a biopesticide?
Beauveria bassiana
Rationale: Beauveria bassiana infects and kills various insect
pests naturally.
18. What is the main advantage of using bait stations for rodent
control?
Limits exposure of non-target animals
