Roaches are one of the most common pests in Southeast Texas and are one of the most feared pest as well. These tenacious insects have been around for over millions of years. Their ability to reproduce rapidly and often enables them to develop resistance to pesticides. The two most common ways roaches gain entrance into a home or business are either transported in or through a crack or crevice from the exterior. Roaches enjoy and need what people need and enjoy - food, moisture and shelter.
