300 Randomized, Scenario-Based Multiple-Choice Questions
Exam Overview
To qualify for a pesticide applicator license in Ohio, you must: (1) pass the Core exam, (2) pass at
least one category exam, (3) submit the application, and (4) pay the license fee. The Core exam
covers general safety for the applicator and the environment. Exams are free, multiple-choice,
and not open book. A photo ID is required. If you fail, you must wait five business days before
retesting.
Key Study Topics: Pest management principles, federal and Ohio pesticide laws, pesticide
labeling, formulations, hazards and first aid, personal protective equipment, environmental
concerns, storage and transportation, emergency response, application procedures, and
professional conduct.
300 Practice Questions
1. The ability of a pest to withstand poisoning from a pesticide even when properly applied is
called:
A) Efficacy
B) Pesticide resistance
, Page 2 of 175
C) Dormancy
D) Antagonism
Correct Answer: B
Each time a pesticide is used, it selectively kills susceptible pests; resistant individuals survive
and reproduce, passing resistance traits to offspring—this is pesticide resistance.
2. What is the primary purpose of pest monitoring?
A) To determine which pesticide to purchase
B) To identify pest type, population, timing, and environmental conditions
C) To eliminate all pests from the area
D) To calculate pesticide costs
Correct Answer: B
Pest monitoring answers four key questions: how many pests, what kind, when are they present,
and what environmental conditions exist—usually done through trapping.

3. Which type of pest requires regular control measures because they are consistently
present?
A) Sporadic pests
B) Migratory pests
C) Continuous pests
D) Potential pests
Correct Answer: C
Continuous pests are consistently present and pose an ongoing threat, requiring regular control
measures.
4. What is suppression in pest management?
A) Keeping a pest from becoming a problem
B) Destroying an entire pest population
C) Reducing pest numbers or damage to an acceptable level
D) Regular monitoring of pest populations
, Page 4 of 175
Correct Answer: C
Suppression involves reducing pest populations or damage to an economically acceptable level
rather than complete elimination.
5. Eradication refers to:
A) Maintaining pests at low levels
B) Preventing pests from entering an area
C) Destroying an entire pest population
D) Using natural predators to control pests
Correct Answer: C
Eradication means destroying an entire pest population, which is rarely achievable except in
isolated or specific situations.
6. Biological control uses which of the following to control pests?
A) Chemical insecticides
B) Living organisms such as parasites, pathogens, or predators
