Why is dust a good alternative for certain applications?

• A. It is a good alternative where moisture from a spray might cause damage.
• B. It is always more effective than sprays.
• C. It leaves no residue on surfaces.
• D. It is inexpensive in all cases.

Answer: (A)

Dust is a good alternative when moisture from a spray could cause damage. Because dust formulations stay dry, they can be applied into cracks, voids, or around delicate surfaces such as electronics, wood, or stored goods without risking water damage, staining, or corrosion. They work by making contact with the pests or by desiccating them, and they tend to remain in place in tight spaces, providing residual control where liquids might run off or be wiped away. It’s not always the best choice for every situation—liquids can knock down large or flying pests quickly, and dusts can be messy or less effective in humid conditions or on exposed surfaces. Costs and availability vary, so the key idea is that dust is preferred specifically when keeping things dry is important.
