How does dampness affect dust products?

• A. It disperses evenly in humidity and improves coverage.
• B. Dampness causes the product to clump, making it difficult to apply in damp or humid environments.
• C. It becomes more toxic to humans in humid conditions.
• D. It dries out quickly and loses effectiveness in humidity.

Answer: (B)

Dust products are dry powders that need to flow freely so they can be evenly distributed. When moisture or humidity is present, the particles tend to stick together and form clumps. Those clumps don’t flow well, can clog dusting devices, and prevent uniform application, especially in damp or humid areas. As a result, coverage is uneven and the product is less effective at contacting pests. Humidity doesn’t increase toxicity and doesn’t cause the dust to dry out and lose effectiveness; it mainly hinders dispersion. So dampness causes the product to clump, making it difficult to apply in damp or humid environments.
