In this study, we evaluated the expansion of a capybara population in a residential park in S\u00e3o Paulo state, and the implications of such expansion to the occurrence of ticks and BSF. The capybara population was quantified during 2004\u20132013. In 2012, there was a BSF human case in the area, culminating in the complete fencing of the residential park and the official culling of all capybaras. Quantification of ticks in the environment was performed by dry ice traps from 2005 to 2018. Domestic dogs in 2006\u20132011 and capybaras in 2012 were serologically tested for the presence of anti-\n                    <jats:italic toggle=\"yes\">R. rickettsii<\/jats:italic>\n                    antibodies. Our results show that capybara numbers increased \u22485 times from 2004 (41 capybaras) to 2012 (230 capybaras).

During 2016\u20132018 (after capybara culling), the number of both species fell close to zero. The low numbers of\n                    <jats:italic toggle=\"yes\">A. sculptum<\/jats:italic>\n                    adult ticks during 2005\u20132006 coincided with relatively low capybara numbers (&lt;80). Thereafter, in 2012, we counted the highest numbers of both\n                    <jats:italic toggle=\"yes\">A. sculptum<\/jats:italic>\n                    ticks and capybaras (230 animals).

Our results support that the emergence of BSF in the residential park was a consequence of the increase of the local capybara population, which in turn, provided the increment of the\n                    <jats:italic toggle=\"yes\">A. sculptum<\/jats:italic>\n                    population.
