Objective To investigate the features of vector ticks in the vegetation of different habitats and locations in Suzhou, China, and to provide a basis for the control of tick-borne diseases. Methods From April to November, 2018, the drag-flag method was used to collect questing ticks from the vegetation at 7 investigation sites of Zhangjiagang, Changshu, Kunshan, and Taicang cities and Huqiu, Wujiang, and Wuzhong districts, once per month. Results A total of 1 759 questing ticks were collected and were identified as one genus and four species by taxonomic identification, i.e., Haemaphysalis flava (99.09%), H. longicornis (0.68%), H. campanulata (0.17%), and H. phasiana (0.06%). A total of 1 501 H. flava ticks were collected in parks/scenic areas and accounted for 85.33%; 175 ticks belonging to 4 species were collected in hillside forests and accounted for 9.95%; 63 H. flava ticks were collected in urban green land and accounted for 3.58%; 20 ticks belonging to H. flava, H. longicornis, and H. campanulata were collected in rural wild grasslands and accounted for 1.14%. A total of 1 399 questing ticks were collected in Zhangjiagang and accounted for 79.53% of all ticks, and 102 (5.80%), 87 (4.94%), 23 (1.31%), 67 (3.81%), 80 (4.55%), and 1 (0.06%) ticks were collected in Taicang, Kunshan, Changshu, Wujiang, Huqiu, and Wuzhong, respectively. Conclusion There are 4 species of questing ticks in the habitats with different vegetation types in Suzhou, and the species and numbers of ticks vary across habitats. Haemaphysalis flava is the dominant species in each type of habitat.
