Which insect problem can be tracked using catch trays?

Catch trays are particularly effective in monitoring Dermestids, which are a group of beetles known for their ability to infest and damage various materials, especially in stored products and museum settings. These trays are designed to capture and collect insects that crawl or fall into them, allowing for easy counting and species identification.

By using catch trays, pest management professionals can determine the presence and population levels of Dermestids in a specific area. This method is beneficial for assessing the extent of an infestation, understanding patterns of pest activity, and evaluating control measures over time. Dermestids are attracted to organic materials, so the use of specific baits in catch trays can enhance their effectiveness in attracting these pests.

Ants and termites, while they can be monitored, are typically tracked using different methods, such as bait stations or monitoring tubes. Bedbugs also require specialized monitoring tools, like bedbug traps or canine detection, due to their unique behaviors and habitats. This delineation of monitoring methods highlights why catch trays are particularly suited for Dermestids rather than the other options provided.
