Which nozzle spray tip is best used for crack & crevice treatments?

• A. Cone nozzle
• B. Pin stream tip
• C. Flat fan tip
• D. Air- assist mist nozzle

Answer: (B)

For crack and crevice treatments, you want a nozzle that delivers a narrow, high-velocity jet that can be directed into tight openings. The pin stream tip provides that pencil-like jet, allowing material to reach deep into cracks and voids where pests hide, with minimal runoff onto surrounding surfaces. Its focused spray also helps reduce off-target drift compared with wider sprays. In contrast, a cone nozzle sprays a broad cone that covers surfaces more than cracks, a flat fan tip delivers a wide fan of liquid ideal for flat surfaces but not for narrow gaps, and an air-assisted mist nozzle creates very fine droplets that drift easily and may not penetrate small openings effectively.
