Abstract: A pest control system comprising a gateway comprising a gateway memory, a wireless communications unit, and an external network communications unit. The system comprises a number of top tree nodes wherein each top tree node has the gateway as a sole parent, wherein each top tree node comprises a node memory and at least one wireless data communication unit, a number of tree nodes, wherein each tree node belongs to one sole tree-and has one sole parent. Each tree node comprises a node memory and at least one data wireless communication unit, wherein each tree has a dedicated slot time during a repeat cycle to avoid interference between different trees.

Abstract: A method for configuring a pest control system is provided. The pest control system includes a gateway and a number of nodes arranged to communicate with each other via wireless data communication; wherein the wireless data communication is performed by using a rendezvous frequency for adding nodes to the system and a network communication frequency for communication between the nodes in the system. A pest control device and a gateway for use in a network of pest control devices of the system are further provided.

Abstract: A system for monitoring rodents in a sewage system, the system including a plurality of monitoring devices placed in manholes of the sewage system, wherein each monitoring device is provided with one or several sensors configured to detect rodents in the sewage system and to generate a sensor data set. A memory configured to hold an identification code, and a data communications module. A server includes a data communications module communicatively connected to the data communication modules of the monitoring devices, wherein the server is configured to receive, from each monitoring device, the sensor data set and the identification code, and based on these data sets identify how populations of rodents move in the sewage system.
