Improper waste handling in urban eateries creates serious environmental and health risks, especially by encouraging the spread of insects and rodents that contaminate food and utensils. This study explored how waste management practices influence pest infestation in eateries across Port Harcourt, Rivers State, Nigeria. Using a descriptive survey design, data were collected from 300 respondents through structured questionnaires. Both descriptive and inferential analyses were applied to test the hypothesis that poor waste handling and pest proliferation do not differ significantly with improved waste management measures. The results showed that most respondents (94%) agreed that insects and rodents contaminate food and utensils, while 86% confirmed that proper storage and regular disposal of waste help reduce pest problems. However, only about half (53.6%) reported that their eateries actually follow recommended hygiene and sanitation guidelines, pointing to major gaps in compliance. The study also identified several challenges: limited awareness of proper waste handling practices (66%), lack of adequate bins (14%), and irregular waste collection services (5.7%). When ranking improvement measures, respondents rated designated waste disposal points (mean = 3.3), timely waste collection (mean = 3.2), and stricter regulatory enforcement (mean = 3.2) as the most effective. In contrast, public awareness campaigns (mean = 1.8) and partnerships with private waste companies (mean = 2.1) were seen as less effective. Overall, the study concludes that improving infrastructure, strengthening waste collection systems, training staff, and enforcing hygiene regulations are essential steps toward better waste management and pest control in urban eateries. It further recommends policy reforms and stronger collaboration among stakeholders to protect public health and enhance environmental sanitation.
