Which of the following is least likely to be used to control a pest?

Biological control
Chemical sprays
Subsoiling
Traps

The correct answer is: Subsoiling

Subsoiling is primarily a soil management practice aimed at improving soil structure, aeration, and drainage. It involves breaking up compacted soil layers to enhance root growth and water infiltration. Although it can indirectly affect pest control by promoting healthier crops, it is not directly aimed at managing or controlling pests. In contrast, biological control involves using natural enemies of pests (such as predators, parasites, or pathogens) to keep pest populations in check. Chemical sprays are formulated products designed specifically to target and kill pests. Traps are often utilized to attract and capture pests, effectively reducing their numbers. Thus, among the options provided, subsoiling most clearly lacks a direct role in pest control, making it the least likely choice used for that purpose.
