Which of the following is a precautionary statement that may be found on a pesticide label?

The statement "Use indoors only" is a precautionary statement that indicates the environment in which the pesticide is intended to be applied. This type of information is crucial for ensuring safety and effectiveness, as some pesticides may be formulated for indoor use due to their properties, potential risks to non-target species, or volatility.

Precautionary statements like this one help users understand the limitations of the product and ensure that it is utilized in a manner that mitigates risks to human health, pets, or the environment. Additionally, they guide users in following best practices for pesticide application, promoting responsible use and compliance with legal regulations.

Remaining choices may not provide precautionary information tailored to usage recommendations, safety, or restrictions, but may relate to usage specifications or educational aspects. However, they do not serve the same primary function of indicating safe use environments.
