This research is a study of pest management systems in Malmö. Malmö is, as many other cities, growing and a node of people's movement. Occurrences of pests have increased in the last decade; this increase is attributed to travel as well as construction and building. What this paper shows is that the structures of pest management must evolve to be more communicative and collaborative. The thesis also adds to the housing crisis debate, as pests in one’s housing have a physical as well as psychological effect.
