Structural Pest Control Applicator Practice Exam

Which of the following statements about a pesticide deposit is NOT true?

1. A deposit is a pesticide that stays on treated surfaces.

2. Pesticide deposits can be difficult to see.

3. Most deposits disappear shortly after application.

4. Pesticide deposits can last a long time on surfaces.

The correct answer is: Most deposits disappear shortly after application.

The statement that most pesticide deposits disappear shortly after application is not true. In practice, pesticide deposits can remain effective on treated surfaces for various durations, depending on several factors such as the type of pesticide, the surface it's applied to, environmental conditions, and how the pesticide interacts with the treated area. While some deposits may degrade or wash away relatively quickly, others can persist for extended periods, providing residual activity against pests. Understanding the longevity of pesticide deposits is essential for pest control applicators to ensure effective pest management. Some pesticides are formulated to have longer-lasting effects, which can be particularly important in ensuring that pests are controlled over time without the need for frequent reapplications. This contrasts with the other statements, which accurately reflect characteristics of pesticide deposits. For example, deposits are often not visible, making them challenging to assess visually, and they can indeed last a significant amount of time after application, depending on environmental factors and the nature of the pesticide.
