Cockroaches are an extremely resilient insect. By examining fossils, it’s been determined that they have been around for over 300 million years. These days, there are more than 4,000 species crawling around. About 60 exist in the United States and around a dozen cause us to get out the insecticide.
The fact that cockroaches have been able to survive for as long as they have has made it extremely difficult in the past to control their population. Years and years of evolution have given them tough flat bodies and large legs for fast running and easy maneuvering. Other factors contributing to their enduring presence are the rapidity and frequency that they lay eggs and their possession of good climbing abilities.
