The document provides examples for calculating the amount of termiticide needed for various termite treatment jobs. It begins with introductory warnings and then presents four examples of calculating termiticide needs for different house structures and situations. The examples show how to calculate the gallons needed for horizontal barriers, vertical barriers, protrusions, and control cracks. Key numbers like 1 gallon per 10 square feet for horizontal barriers and 4 gallons per 10 linear feet for vertical barriers are provided. The final example notes that houses may have non-square shapes that require calculating areas and perimeters of geometric shapes.
