Which of the following conditions will most likely lead to see issues with nozzle clogging?

Using unfiltered products is the condition that will most likely lead to issues with nozzle clogging. When products are not properly filtered before application, they can contain suspended solids, debris, or other particulates that may not dissolve in the spray mixture. As these particles travel through the nozzle, they can accumulate and create blockages, leading to uneven spray patterns or complete nozzle failure.

Unfiltered products can introduce contaminants that are more difficult to manage, often resulting in a range of clogging issues that can impede the effectiveness of pest control applications. Regularly filtering products before use helps ensure that only the intended active ingredients reach the nozzle, minimizing the risk of clogs and maintaining consistent application quality.

Other options may contribute to various spraying issues, but unfiltered products pose a significant risk when it comes specifically to nozzle performance.
