Which process involves tarping and gassing the structure to eliminate drywood termites?

1. Spot treatment

2. Fumigation

3. Moisture control

4. Physical removal

The correct answer is: Fumigation

Fumigation is the process that involves tarping and using gas to eliminate drywood termites. This method is particularly effective for addressing extensive infestations because it allows the gas to penetrate all areas of the structure, including hard-to-reach spots where termites might be hiding. The tarping helps contain the gas, ensuring that it reaches a sufficient concentration to effectively kill the termites throughout the entire building. This process is conducted in a controlled manner by trained professionals, who ensure that safety protocols are followed for both the occupants and the pets, as the gases used can be hazardous. Fumigation is often employed when other treatment methods are not sufficient or practical for heavy infestations of drywood termites, making it a go-to option in severe cases. In contrast, spot treatment typically targets small areas of infestation, moisture control focuses on preventing conditions that favor termite activity, and physical removal involves manual elimination of pests without the use of chemicals. These alternatives have their respective uses but do not provide the comprehensive coverage and effectiveness that fumigation does for drywood termites.
