Which formulation is odorless and reduces indoor air pollutants during application?

• A. Wet sprays
• B. Dust formulations
• C. Pastes and gels
• D. Aerosols

Answer: (C)

The concept being tested is choosing a pest-control formulation that minimizes odor and indoor air pollutants during application. Pastes and gels fit this because they are thick, non-volatile carriers applied directly to cracks and crevices and tend to stay in place. They don’t rely on solvents or propellants that vaporize, so they are essentially odorless and generate very little airborne material. This keeps indoor air cleaner during application. In contrast, wet sprays and aerosols use solvents and propellants that vaporize and drift through the air, creating noticeable odors and increasing indoor pollutants. Dust formulations can be relatively odorless, but they may become airborne as the area is disturbed, contributing to air contamination. Therefore, pastes and gels are the best choice for odorless applications that reduce indoor air pollutants.
