A pest control system and a method for building a network of pest control devices

The disclosure relates to a pest control system (1) comprising a gateway (2) comprising a gateway memory (21), a wireless communication unit (22), and an external network communication unit (23); a number of top tree nodes (tn1-tn6) wherein each top tree node has the gateway (2) as a sole parent, wherein each top tree node (tn1-tn6) comprises a node memory (nm) and at least one wireless data communication unit (nc); a number of tree nodes (n1,n2,n3,n4), wherein each tree node belongs to one sole tree (t1-t6) and has one sole parent, wherein each tree node (n1,n2,n3,n4) comprises a node memory (nm) and at least one data wireless communication unit (nc); wherein each tree (t1-t6) has a dedicated slot time during a repeat cycle to avoid interference between different trees. The disclosure further relates to a method for building a network of pest control devices and a method of controlling the signal strength of a pest control network.
