In México, T. muris has been recorded from M. musculus in Hidalgo (Pulido-Flores et al. 2005) and Tabasco ( Cigarroa-Toledo et al. 2017), R. rattus in México City (García-Prieto et al. 2012), R. norvegicus in México City (Zerecero 1943) and Tabasco ( Cigarroa-Toledo et al. 2017), and H. irroratus in Morelos ( Eslava-Araujo 2005).

In Yucatán, this species has been previously reported from M. musculus in three localities in Mérida and Opichén (Panti-May et al. 2015, 2017).
