Cockroaches

Introduction

Cockroaches, one of the oldest and most resilient pests, are common in urban environments. In Australia, out of 550 species, only a few are household pests, thriving in warm and humid conditions like kitchens and bathrooms​​.

Types of Cockroaches

Common household cockroaches include:

  • German Cockroach: Small and pale brown, known for rapid reproduction and resistance to treatments​​.
  • Australian Cockroach: Prefers outdoors and organic matter but may invade homes​​.
  • American Cockroach: Larger species, attracted to sweet foods and can fly​​.
  • Oriental Cockroach: Dark and usually found in damp areas, heavily dependent on water​​.
  • Smoky Brown Cockroach: Notable for its size and flying ability, often invading homes through open areas.
Signs of Cockroach Infestation

Cockroach infestations are indicated by sightings during the day, droppings that resemble coffee grounds, and a distinctive oily, musty odor​​.

Preventative Measures

Good hygiene, regular cleaning, sealing entry points, and proper storage of food and waste are crucial to prevent infestations​​​​.

Treatment

Professional treatments vary by species but typically include sprays and gels, focusing on long-term control and breaking the breeding cycle, particularly for the German cockroach​​.
