Fumigation involves exposing target pest to a pesticide in which state?

• A. Liquid
• B. Gaseous
• C. Solid
• D. Aerosol

Answer: (B)

Fumigation relies on a pesticide in the gaseous form. The whole goal is to fill the enclosed space with gas so the pest is exposed no matter where it hides, such as cracks, voids, or porous materials. Gas-phase fumigants diffuse through spaces and reach pests in hidden locations, which is why the gaseous state is essential. Liquids or solids wouldn’t reach those areas unless they’re converted to gas, and aerosols are droplets suspended in air—not a true gas—so they don’t provide the same uniform, whole-space exposure. So the correct idea is that fumigation uses a pesticide in the gaseous state.
