Ticks are not, in any manner, selected for by Virginia opossums.” He cites a 2021 peer-reviewed paper called “Are Virginia opossums really ecological traps for ticks? Groundtruthing laboratory operations,” by Dr. Cecilia Hennessy and Kaitlyn Hild of Eureka College’s Division of Science and Mathematics.
