Pest Control Technician Practice Exam 2026 – Complete Prep Guide

Improper pesticide application can lead to several serious consequences, making the option that encompasses all these effects the most appropriate choice. When pesticides are not applied correctly, their effectiveness can be significantly diminished. This reduced efficiency often results in the need for additional treatments, leading to an increased cost and effort for pest control.

Additionally, improper application can contribute to the development of pest resistance. When pests are exposed to sub-lethal doses of pesticides, they may survive and reproduce, leading to a population that is more resistant to that pesticide over time. This resistance complicates future pest control efforts, as it may necessitate the use of more potent or different chemicals.

Environmental contamination is another critical consequence. Pesticides can leach into soil or water systems when misapplied, posing risks to non-target organisms and disrupting local ecosystems. This can lead to long-lasting environmental damage, affecting wildlife and potentially entering the human food chain.

Thus, the combination of these outcomes—reduced effectiveness in pest control, increased chances of pest resistance, and the risk of environmental contamination—supports the conclusion that all of these factors collectively represent the consequences of improper pesticide application.
