What treatment method involves removing soil to within about 1 foot above the footing and treating it with termiticide as it is replaced?

Complete
Trenching
Digging
Excavation

The correct answer is: Trenching

The treatment method that involves removing soil to within about 1 foot above the footing and treating it with termiticide as it is replaced is known as trenching. This method is specifically designed to create an effective barrier against termites by allowing the termiticide to penetrate the soil around the foundation of a structure. During trenching, the soil is excavated, and the area is treated with the chemical solution. Once the treatment is applied, the soil is then returned to its original position, ensuring that the termiticide is in direct contact with the areas where termites are likely to travel. This method is particularly beneficial for providing targeted protection and is often a crucial part of a comprehensive termite treatment plan. The other options, while they may seem related, do not accurately describe the specifics of the treatment process involved in trenching. For example, complete treatment may imply a broader approach and doesn't specifically address the technique of soil removal and replacement with treatment. Digging and excavation could refer to any form of soil removal without the specific context of treating for termites. Therefore, trenching stands out as the correct identification for this method of pest management.
