Which action should be taken with openings before applying thermal fog?

• A. Never allow people in the area.
• B. Direct fog toward caulking.
• C. Direct fog as near to the ground as possible and apply during evening, night, or early morning.
• D. Use only at noon.

Answer: (C)

Controlling where the fog goes and when you apply it is key to an effective and safe thermal fogging treatment. Directing the fog as near to the ground as possible targets the pests that hide along foundations, under baseboards, and in cracks at floor level, where they are most likely to be found. Applying during evening, night, or early morning takes advantage of cooler conditions and reduced human activity, which minimizes exposure through openings and helps the fog linger long enough to contact harborage. Directing fog at caulking isn’t aimed at pest hiding spots and isn’t the goal, and using the fog at noon increases risk to people and reduces effectiveness due to rapid dispersion.
