Fumigation Volume Calculator

1. Enter the structure's length and width. Measure the exterior dimensions of the building footprint. For L-shaped or irregular buildings, estimate the bounding rectangle or calculate sections separately.

2. Set the average height to eaves. This is the wall height from ground to the roofline. Standard single-story homes are 8-9 feet; two-story homes are 16-18 feet.

3. Include the attic if applicable. For peaked roofs, enter the height from eaves to peak. The calculator uses a pyramidal formula (1/3 of the rectangular volume) to estimate attic space.

4. Add basement, garage, or shed. Toggle each section on and enter dimensions. All volumes are summed for the total fumigation volume.

The calculator uses standard geometric formulas to compute total enclosed volume.

The attic calculation uses the pyramidal roof formula, which estimates the average enclosed space under a peaked roof as one-third of the full rectangular volume. This is a standard approximation used in the fumigation industry.

Gas dosage at 1 lb per 1,000 cubic feet is a reference rate for sulfuryl fluoride (Vikane). Actual dosage varies by target pest, temperature, and exposure duration. Always reference the product label and state regulations.
