1. 1.5

2. 4

3. 12

4. 8

The correct answer is: 8

The application rate of termiticide in exterior soil treatment is crucial for effectively creating a barrier against termites. The correct answer is eight gallons per 10 linear feet for each foot of depth from the grade level to the footing. This dosage is based on industry standards that ensure thorough penetration and coverage of the soil surrounding the foundation. The rationale for this specific volume is to ensure that an adequate concentration of the termiticide is present in the soil, which is essential to prevent termite activity. The depth of treatment is particularly important since termites tend to enter structures from the ground, making it vital that the treatment reaches down to where they are most likely to breach the foundation. Proper volume application is in accordance with pest control best practices and contributes to the long-term efficacy of the treatment. This ensures that the chemical barrier not only deters existing infestations but also precludes new termite colonies from establishing near the structure.
