-

 

Introduction

Cockroaches are among the most resilient pests, capable of thriving in various environments. They can invade homes, offices, and businesses, creating unsanitary conditions and spreading diseases. Understanding the different types of roaches is essential to identifying infestations and taking effective control measures.

In this detailed guide, we’ll explore the most common cockroach species, their distinguishing characteristics, preferred habitats, and the best ways to manage infestations. 

What Are Cockroaches?

Cockroaches are insects belonging to the order Blattodea, known for their adaptability and survival skills. There are over 4,500 species of cockroaches globally, but only about 30 are associated with human habitats. Despite their reputation as pests, most cockroach species prefer outdoor environments and play a role in the ecosystem as decomposers.

  • Size: Small, about ½ to ⅝ inches long.

  • Use insect growth regulators (IGRs) to disrupt their life cycle.

5. Smoky-Brown Cockroach (Periplaneta fuliginosa)
