There are many things that today’s cities strive to earn a top 10 position in, but top 10 cities for most rodents and cockroaches is surely not one of them. Here in Houston we have earned the dubious distinction of being in the top 10 list for the highest rates of rats and cockroaches when comparing the 25 largest cities in the United States. According to the most recent American Housing Survey, Houston ranked 4th highest in rat infestation, 9th highest in cockroaches, and 10th overall in evidence of unspecified rodents. The rodent population is surely a concern when you consider all that these little pests imply.
