PestWatcher developed a completely new business concept for integral pest management. Through the use of sensors and connectivity in pest traps and bait stations, 24/7 monitoring of pest activity is possible. This saves customers on the costs of pest management and with the digital log, organizations fully comply with the IPM protocol for the use of pesticides.


Castermans Connected advised PestWatcher on the business model where PestWatcher becomes a platform where end users (often facility managers) and independent pest controllers work together. For the technical development, Castermans Connected made an introduction to an industrial design agency for further product development and advised on the connectivity to be applied.


“Castermans Connected kept us sharp during all phases of our innovation process, both in terms of business aspects and the application of technology and product development”
