Q: Why are cockroaches so successful as pests?


By: Dr. Janis Reed, BCE, Technical Services Manager with CSI

This can be boiled down to one word: Reproduction. Cockroaches ability to reproduce quickly is why they are successful. German cockroach females typically develop in less than three months from egg to adult. This generation time means cockroach populations can build rapidly. Additionally, a single German cockroach female can produce 40+ eggs per ootheca and she can make several of these egg cases in her lifetime.
