Best applicator to treat crack and crevices?

• A. Long-range wand
• B. Fine spray mist
• C. Wide spray nozzle
• D. Narrow diameter tube

Answer: (D)

Precision control is essential when treating cracks and crevices. A narrow diameter tube lets you insert into tight openings and dispense a small, focused stream right where pests hide, delivering the product directly into the crevice. This targeted placement means you get effective deposit inside deep or narrow spaces while minimizing overspray onto surrounding surfaces and reducing waste.

In contrast, a long-range wand is built for distance and larger areas, not for confined gaps. A fine spray mist creates many tiny droplets that can drift away from the target and may not stay in the crack. A wide spray nozzle covers a broad area, which isn’t efficient for cracks and crevices and tends to waste product and increase exposure of non-target surfaces.

So, the tool that provides precise, direct delivery into small openings is the best choice for crack-and-crevice treatment.
