Study on the impact of urban insect presence on user experience and behaviour in public spaces: case study in Colombo

Abstract

Urban public spaces are vital for social interaction, recreation, and psychological well-being, yet the presence of insects in these environments can significantly shape user experience and behaviour. This study investigates the impact of urban insects on user perception and behaviour in selected public spaces in Colombo, focusing on both non-beneficial (mosquitoes, houseflies, cockroaches) and beneficial (butterflies, ladybugs, dragonflies) species. Data were collected through field observations, semi-structured interviews, and a scenario-based questionnaire administered to 73 respondents across Nugegoda, Viharamahadevi Park, and Battaramulla. Results indicate that non-beneficial insects negatively influence perceived cleanliness and comfort, prompting avoidance behaviours, while beneficial insects generally enhance aesthetic appreciation and engagement with the space. Findings also reveal that environmental conditions, waste management practices, and green infrastructure strongly mediate insect presence and its impact on users. The study underscores the importance of integrating insect-conscious design and management strategies in urban public spaces to balance ecological health with user comfort and usability.
