Do dusts generally have a longer residual life than some liquids?

• A. True
• B. False

Answer: (A)

Dust formulations typically have a longer residual life compared to many liquid formulations. This is largely due to their physical properties and how they interact with the environment. Dusts can adhere to surfaces effectively and maintain their active ingredient for extended periods, particularly in dry conditions. When applied, dusts create a thin layer that can persist without degrading or being washed away easily, making it possible for the active substances to remain effective over time. In contrast, liquids often rely on evaporation and can easily be affected by weather conditions such as rain or high humidity, which can reduce their effectiveness more quickly. Some liquids may also require reapplication sooner due to their tendency to degrade or wash away. Consequently, dusts are valued in pest control for their longevity and effectiveness, allowing for less frequent applications while still providing the desired pest management outcomes. This characteristic makes dusts particularly useful in scenarios where long-lasting control is essential.
