SELECTIVE DETECTION OF BED BUGS

A device, system, and method of controlling pests are disclosed. A pest control device includes a sensor having a sensor cell and a controller. A surface of the sensor cell is coated with an agent that reacts with a targeted biochemical analyte secreted by pests. The controller is coupled to the sensor and is configured to receive sensor data from the sensor cell indicative of a rate of change in sensor mass detected on the surface of the sensor cell, determine whether the rate of change in the sensor mass based on the received sensor data exceeds a predefined threshold rate, and transmit a pest detection alert notification to a server in response to a determination that the rate of change exceeds the predetermined threshold rate.
