What distinguishes fumigants from aerosols?

• A. Fumigants are solid substances, while aerosols are liquids
• B. Fumigants are gases, and aerosols are droplets suspended in air
• C. Fumigants are only used outdoors; aerosols are indoor products
• D. Fumigants can only target insects; aerosols can target all pests

Answer: (B)

The distinguishing factor between fumigants and aerosols lies in their physical state and method of dispersion. Fumigants are gaseous substances that penetrate structures and materials, allowing them to control pests effectively throughout an entire area, including hard-to-reach spaces like cracks and crevices. This gaseous state enables fumigants to diffuse and spread evenly, creating a homogeneous atmosphere that is lethal to targeted pests. On the other hand, aerosols consist of tiny liquid droplets suspended in air. These droplets can settle on surfaces and be primarily effective in the areas they contact, which limits their effectiveness compared to fumigants when it comes to penetrating materials or covering larger areas. The other options provide incorrect characterizations regarding the nature and use of fumigants and aerosols.
