What is the function of a damp newspaper in pest control?

The function of a damp newspaper in pest control is primarily to attract pests to a specific area. When used in pest management, a damp newspaper can be an effective tool for capturing insects such as roaches or earwigs, as these pests are drawn to dark, moist environments that resemble their natural habitats. By placing a damp newspaper in an area where pest activity is suspected, technicians can lure these insects into a confined space for easier monitoring or removal.

While the other options may have some relevance to pest control in different contexts, they do not accurately describe the function of a damp newspaper in this scenario. For instance, a damp newspaper is not used as a carrier for pesticides, nor does it serve the purpose of locating heating ducts or keeping insects away. Instead, it acts as an attracting medium that facilitates the identification or capture of pests.
