What is the purpose of using a tarpaulin during fumigation?

• A. To attract pests
• B. To retain fumigants
• C. To increase humidity
• D. To block sunlight

Answer: (B)

The purpose of using a tarpaulin during fumigation is to retain fumigants. This is crucial because fumigation relies on the effective containment of gases used to eliminate pests. By covering the area being treated with a tarpaulin, the fumigants can be kept within a designated space, allowing for a higher concentration of the chemical to remain in contact with the target pests for a prolonged period. This enhances the efficacy of the treatment, ensuring that it penetrates into all areas where pests might reside. Retaining the fumigants minimizes the risk of leakage and exposure to the outside environment, contributing to the safety and effectiveness of the fumigation process. The other options do not align with the primary function of a tarpaulin in fumigation. Attracting pests is counterproductive to the aims of fumigation, which is to eliminate pest populations. While increasing humidity can assist in certain pest management scenarios, it's not the primary role of a tarpaulin. Lastly, blocking sunlight is not relevant in the context of fumigation as the process focuses more on gas retention rather than light exclusion.
