What is a consequence of applying pesticides too frequently in an area?

• A. Lower costs
• B. Secondary pest outbreaks or a resurgence of the pest
• C. Improved pollinator health
• D. Longer-lasting pest control

Answer: (B)

Frequent pesticide use disrupts the balance of the ecosystem in and around treated areas. It doesn’t just kill the target pest; it also wipes out beneficial organisms that normally help keep pest numbers down, such as predators and parasites. With those natural enemies reduced, pest populations can rebound quickly once the chemical wears off, leading to outbreaks or a resurgence. Repeated applications also apply selection pressure, which can favor resistant individuals and make future control harder and more costly. So, overuse is more likely to produce secondary pest outbreaks rather than lower costs, improved pollinator health, or longer-lasting, effective control.
