What is the significance of sealing a structure before fumigation?

• A. To allow ventilation
• B. To contain the fumigant and enhance effectiveness
• C. To speed up the process
• D. To reduce costs

Answer: (B)

Sealing a structure before fumigation is critically important because it helps contain the fumigant within the area being treated. This containment enhances the effectiveness of the fumigation process. When the structure is properly sealed, the fumigant can reach and penetrate all areas where pests may be hiding, ensuring a comprehensive treatment. This containment minimizes the risk of losing the fumigant to the outside environment, allowing it to work effectively and efficiently over the required exposure time. In contrast, allowing ventilation would dilute the fumigant concentration, making it less effective in exterminating pests. Speeding up the process could compromise the treatment's thoroughness and effectiveness, while reducing costs may lead to cutting corners, which isn't advisable since proper fumigation requires a controlled environment to be successful.
