[1] The Texas blind snake spends the vast majority of its time buried in loose soil, only emerging to feed or when it rains and its habitat floods with water.

In northern Mexico it has been reported in Chihuahua, Coahuila, Tamaulipas, Nuevo León, San Luis Potosí, Veracruz, Querétaro, Hidalgo, and Puebla.

[citation needed] The type locality given by Baird and Girard is "Between San Pedro and Camanche [sic] Springs, Tex."

[2] R. dulcis is found in a variety of habitats including desert, grassland, shrubland, savanna, and forest.

[1] Gauging wild blind snake populations is virtually impossible due to their secretive nature.

However, like many other native Texas species, R. dulcis is known to be detrimentally affected by the red imported fire ant.
