Pale-bordered field cockroaches are omnivorous, which means it will eat just about anything it can. These cockroaches are scavengers who will dine on meats and grease, starchy foods, sweets and more. If there is no other food source, they can even become cannibalistic and eat each other, however that rarely happens in areas that have a high human population.
The pale-bordered field cockroach is mainly an outdoor species, and can often be found in leaves and shrubs. They are sometimes seen outdoors in gardens and landscapes through much of the southern United States. While they mainly live outside, they can and do make it inside into houses, barns and almost any place that is dark and damp. According to Mississippi State University's entomology department, these cockroaches are native to Mexico and have been seen in south Texas for at least a century. They've made their way to eastern states fairly recently.
