This species has been found naturally infected with Trypanosoma cruzi, and is potentially an important vector of Chagas' disease because it colonizes human habitats; it is also frequently found in peridomestic situations, such as in chicken houses, pigeon coops, and goat and other corrals. It is also found in sylvatic conditions: under loose bark of trees, between cactus trunks, under rocks together with rodents and toads, under trunks of fallen trees where geckos also occur, and in nests of birds (Lent & Wygodzinsky 1979).
