Simple SummaryControl of pests, such as rodents, based on preventive measures and reduced use of non-chemical control is called integrated pest management. Considering the present number of reported rodent infestations, it seems unlikely that the public has much knowledge about rodent pest prevention or integrated pest management. The aim of this study was to find out how much members of the public know about rodents and IPM, and to compare the results with the expectations of pest controllers. In total, 314 members of the public and 86 people working in the pest control sector responded to our online questionnaires. The results show that members of the public have a reasonable level of knowledge regarding preventive measures against rodent control, which are part of integrated pest management. People working in the pest control sector underestimate the public’s knowledge of preventive measures, such as ways of excluding rodents and hygiene measures. Such underestimation may affect their communication with potential clients.Integrated pest management (IPM) involves the control of pests, such as rodents, based on preventive measures and reduced use of chemical control. In view of the number of reported rodent infestations, it appears unlikely that the public has much knowledge about rodents. The objectives of this study were (i) to assess the knowledge and opinions of the public regarding prevention and control of rodent nuisance, and (ii) to assess whether pest controllers have an accurate idea of the knowledge and opinions of the public. The sample contained a total of 314 members of the public and 86 people working in the pest control sector. Responding members of the general public were asked about their knowledge and opinions about IPM in a questionnaire, whereas people working in the pest control sector were asked if they thought the general public had this knowledge and/or opinions. The results show that members of the public have a reasonable level of knowledge regarding preventive measures against rodents, which are part of IPM. People working in the pest control sector underestimate the public’s knowledge of preventive measures, such as perimeter exclusion and hygiene measures. Such underestimation may affect their communication with (potential) clients.
