This study analyzed the types of insect vectors in dumpsite locations and the microorganisms associated with the insect vectors and dumpsites. The physicochemical and heavy metal content of the soil samples were also determined. Bacteria and fungi were isolated from the soils, housefly and cockroaches collected from the dumpsites. Atomic absorption spectrophotometer was used to determine the mineral content of the soil samples. Bacterial and fungal counts were also determined using the Quebec colony counter. Dehydrogenase, phosphatase, catalase, urease and peroxidase activities were estimated. Of the ten bacterial species identified Pseudomonas aeruginosa was the most prevalent isolate occurring at all the samples collected with a frequency of 20.3% while Streptococcal faecalis had the least percentage frequency of 3.1%. Seven fungal genera were identified. They include; Aspergillus niger, Trichoderma spp, Penicillium spp. The study showed a statistically significant (P
