More than 11% of households nationwide reported seeing roaches in their homes during a 12-month period, according to a U.S. Census survey from 2019.
Roaches enter homes through cracks and crevices and are attracted to food. Building traits more frequently associated with roach sightings include sagging roofs, holes in the roof, cracks inside walls, and outside walls that slope, lean, or buckle.
Roaches tend to be more common in Southern states. In the two Texas cities specified in the survey, about 35% of Houston metro area households and 18% of Dallas metro area households reporting sightings.
