What method is commonly used to detect the presence of some pests?

1. Trapping

2. Spraying chemicals

3. Visual inspections

4. Using natural predators

The correct answer is: Trapping

Trapping is a widely used method for detecting the presence of various pests. This technique involves placing baited traps in areas where pests are suspected to be active. Once pests enter the traps, their presence can be confirmed based on the number and type of pests captured. Trapping is effective for monitoring populations, understanding pest behavior, and making informed decisions about control measures. It is particularly useful for pests that may be elusive or difficult to spot during visual inspections. While visual inspections can be helpful, they rely on the ability of the inspector to find and identify pests, which may be challenging if the pests are not visible. Spraying chemicals is more focused on control rather than detection, and using natural predators primarily addresses management rather than identifying the initial presence of pests. Trapping thus serves as a practical and proactive approach to monitoring pest populations efficiently.
