For application into narrow cracks and crevices, which tool is recommended?

• A. Broad spray nozzle
• B. Narrow diameter tube
• C. Fine mist sprayer
• D. Hose-end sprayer

Answer: (B)

Targeted placement into small gaps needs a tool that can fit into the opening and deliver product directly where pests hide. A narrow diameter tube acts as a slender conduit that you can insert into cracks, allowing precise application with minimal overspray and reduced exposure to non-target areas.

A broad spray nozzle creates a wide plume, which can’t reach tight openings and wastes product by spraying where it’s not needed. A fine mist sprayer produces tiny droplets that may drift away with air currents and often won’t reach deep into cracks, reducing effectiveness. A hose-end sprayer is designed for larger, open areas and can be hard to control in tight spaces, making precise placement difficult.

So the narrow diameter tube is the best choice for getting the product where it’s needed in narrow cracks and crevices.
