Pacific Beetle Cockroaches: Identification, Habitat, Behavior, and Control

Pacific Beetle Cockroaches, scientifically known as Diploptera punctata, are a peculiar species of cockroach originating from Asia’s Pacific regions. These insects are unique because they are viviparous, meaning the females give live birth, unlike many other insects that lay eggs.


Pacific Beetle Cockroaches are about 1 to 1.5 inches long when mature. They have shiny, stout bodies ranging from light tan to dark brown. Unlike some other cockroach species, males and females have fully developed wings but rarely fly.

Life Cycle and Habitat

The life cycle of Pacific Beetle Cockroaches consists of three stages: nymph, subadult, and adult. Uniquely, the female Pacific Beetle Cockroach nurtures her embryos internally, providing them with nutrition through a substance similar to mammalian milk, and gives birth to live young ones.

Pacific Beetle Cockroaches are typically found in warm, humid environments. Although they rarely infest homes, they can become pests in greenhouses or where they are kept as pets.

Extermination Techniques

In the rare case where Pacific Beetle Cockroaches become pests, the following eradication strategies can be used:

  1. Insecticides: Insecticides, particularly those formulated for cockroaches, can be effective when used correctly.
  2. Baits: Baits can also be an effective way to control a Pacific Beetle Cockroach population. Place these in areas where the cockroaches are frequently seen.
  3. Professional pest control: If the infestation is significant, professional pest control is the recommended course of action. We can assess the situation and implement the most effective treatment strategy.


Preventing an infestation is key. Try these techniques:

  1. Keep areas clean, particularly where food is stored.
  2. Regularly inspect areas like greenhouses for signs of infestation.
  3. If keeping these cockroaches as pets, ensure their enclosure is escape-proof.
