Urban, tourist and recreational environments are ideal places for the spread of ticks to new areas. The increasing presence of wild animals in urban environments can lead to increased exposure and risk of infestation by dangerous parasites in humans and pets. Increased pace of urbanization relates to human mobility, long-distance trade and interactions with nature between humans and companion animals, which could change epidemiological conditions in urban and peri-urban areas. In 2017–2018, 2,777 ticks were collected in selected areas of the Małopolska and Silesian provinces: 2,643 Ixodes ricinus (95.2%), 107 Ixodes hexagonus (3.9%), 23 Ixodes crenulatus (0.8%), 3 Dermacentor reticulatus (0.1%) and 1 Ixodes apronophorus (0.03%), from 1,209 dogs and 399 cats. Ixodes ricinus is of the greatest medical, veterinary and economic importance in the transmission of many pathogens of tick-borne diseases. The widespread travel of humans with their pets is likely to have a key impact on the existing epidemiology situation of many ectoparasites and may lead to a higher frequency of rare or new parasitic diseases.
