Objective: To explore the spatial distribution characteristics of the peak density of rodents and mosquitoes in the main urban area of Hefei, and analyze the spatial clustering. Methods: The survey data of the peak density of rodents and mosquitoes in the main urban area of Hefei in 2024 (May–June) was collected, and a thematic map of point pattern was drawn to analyze the spatial distribution characteristics using Ordinary Kriging interpolation and spatial autocorrelation. Results: The average density of rodents and mosquitoes in the main urban area during the peak density was 0.91% and 3.50 per/(light·night), respectively. The interpolation ranges of rodent and mosquito densities were 0.03–3.22% and 0.04–13.80 per/(light·night), respectively, which made the fluctuation range smaller and the density range narrower compared with the actual density range, but the distribution of the two were basically the same. The Moran’s I values of rodent and mosquito densities were 0.508 and 0.347, respectively (all Z > 0, all P < 0.010). Conclusions: The density of rodents and mosquitoes in the main urban area was generally at a low level, with obvious differences in spatial distribution characteristics, but presented a spatial pattern of high in the east and low in the west, high in the north and low in the south, with positive correlation clustering. More attention should be paid to the risk of hemorrhagic fever with renal syndrome, and other related infectious diseases in key areas and streets. Vector control measures with key points, key linkages and differentiation should be adopted.
