What is the main function of cold foggers in pest management?

The main function of cold foggers in pest management is to break liquid into small droplets for application. This technology allows for a fine mist of pesticide solution to be dispersed over large areas, ensuring thorough coverage on various surfaces where pests may be present. The small droplet size enhances the efficiency of the pesticide, allowing it to penetrate into areas that are difficult to reach and increasing its effectiveness.

In contrast, the other options do not align with the primary purpose of cold foggers. They do not generate heat for evaporation, nor do they attract pests or kill them instantly. The primary design of cold foggers is centered around creating a mist that ensures an even distribution of the pesticide, which is crucial for effective pest management.
