Most people would rather squash a cockroach than study it, but these much-maligned insects are fascinating creatures that warrant our attention, especially because they live so close to us — often right inside our own homes. Even though we humans generally associate cockroaches with filth and disease, the reputation may be worse than the reality. With a clever story line combining useful scientific information and amazing upclose footage of roaches in their element, “Cockroach” may not be a documentary series for the squeamish, but it is for the curious. It’s the perfect opportunity to learn something about an insect most people would rather not think about, but which touches our lives every day.
