Which monitoring tool uses chemicals to attract pests?

The correct answer is a pheromone trap. Pheromone traps are specifically designed to use chemical attractants—often mimicking the natural pheromones produced by insects—to lure pests into the trap. These traps exploit the insects' natural behaviors and mating signals, making them highly effective for monitoring and controlling pest populations.

Pheromones are species-specific, so these traps can target particular pests without attracting non-target species. This specificity enhances their effectiveness and minimizes environmental impact by not indiscriminately attracting or killing beneficial insects.

In contrast, sticky traps rely on a coating that physically captures pests that come into contact with the sticky surface, while light traps attract insects using UV light. Static traps typically do not utilize any attractants but may serve as containers for monitoring purposes.
