The primary use of sticky traps in pest control is to monitor pest activity.

• A. Extermination
• B. Population reduction
• C. Attracting predators
• D. Monitoring

Answer: (D)

Sticky traps are used to gather information about pest presence and activity, not to wipe out a population. By placing them in likely problem areas and checking them over time, you get a live sample of which species are around, roughly how many are present, and how active they are. This monitoring helps you see trends, confirm if a pest problem is growing or subsiding, and decide when and what kind of control measures to apply. It also lets you verify whether a treatment is working after you implement it. While traps may capture some individuals, they’re not a reliable method for extermination or achieving substantial population reduction on their own. They don’t attract predators as a control strategy; their purpose is to monitor and inform management decisions within an integrated pest management approach.
