Abstract

A pest control system includes pest control devices installed about an area or building. These devices each include a bait member and a wireless communication circuit. The wireless communication circuit may be in the form of a passive RF tag that transmits information indicative of bait status and an identifier unique to each pest control device. The wireless communication circuit can be configured in a first assembly for detecting the presence of one or more pests and a second assembly for delivering a pesticide once pests are detected. The assemblies are interchangeable within a pest control device housing. The wireless communication circuit is connected to a sensor having an electrically conductive element that can be comprised of a nonmetallic material, such as a carbon-based ink. One or more connection members electrically couple the wireless communication circuit and the sensor. These members are comprised of an electrically conductive, elastomeric compound, such as a carbon-filled silicone rubber.
