What best describes a Cyclone Spreader?

• A. A manually operated granular applicator.
• B. A device that uses a rotating disc to fling granules outward.
• C. Common use: Treating small, isolated larval habitats like woodland pools.
• D. A sprayer for aerial application of larvicides.

Answer: (C)

A Cyclone Spreader is a handheld or backpack device designed to apply granular larvicides directly to small, discrete mosquito habitats. Its real strength is targeting tiny, isolated waters—like woodland pools—where larvae accumulate, ensuring the larvicide is placed precisely where it’s needed without treating large surrounding areas. While the mechanism may involve a disc or similar action to spread the granules, the key point is its use in small habitat treatment. It isn’t meant for aerial spraying, and it isn’t simply a general manual spreader used for broad-area applications.
