What should be installed to monitor a potential roach issue if no roaches are seen during inspection?

Installing sticky traps is an effective method for monitoring a potential roach issue, even when no roaches are observed during an inspection. Sticky traps are designed to capture and retain insects that come into contact with their adhesive surface. This allows for continuous monitoring of roach activity over time, providing valuable data about their presence and movement patterns. The traps can be placed in strategic locations where roaches are likely to hide or travel, such as along walls, behind appliances, or in dark corners.

Additionally, sticky traps are helpful in identifying the level of infestation and can serve as an early warning system. If roaches are detected on the traps, it indicates the potential for an infestation and allows for timely intervention.

Other options, while potentially useful in different contexts, do not provide the same level of ongoing monitoring as sticky traps. Hunting cameras and heat sensors primarily work for other types of monitoring and may not specifically target roaches. Pheromone lures can attract roaches but may not capture them, making sticky traps the more effective choice for assessing and monitoring potential roach issues.
