Surinam Cockroaches Guide

The Surinam Cockroach, scientifically termed Pycnoscelus surinamensis, is a unique and intriguing species with a global distribution. Despite its name, this species is believed to originate from Asia and has spread worldwide due to human activity. Uniquely, this species reproduces parthenogenetically, meaning all individuals are female and capable of producing offspring without needing males.


Surinam Cockroaches are moderate-sized, typically measuring up to an inch. They have a shiny, dark brown to almost black body, with a tan or lighter coloration on the edge of the thorax and head. The adult females, the only sex observed, have short, functionless wing pads and cannot fly.

Life Cycle and Reproduction

The life cycle of Surinam Cockroaches is quite remarkable due to the lack of males in the population. The females reproduce through parthenogenesis, a form of asexual reproduction. The female produces an ootheca (egg case), which she carries within her body until the eggs inside are ready to hatch into nymphs.

The nymphs, which look like smaller versions of the adults but with a more reddish-brown coloration, undergo several molts for 4-6 months before they reach maturity. The entire life cycle from egg to adult can take 5 to 7 months, depending on the environmental conditions.

Habitat and Behavior

Surinam Cockroaches are primarily nocturnal insects that prefer warm, moist environments. They are burrowers living in soil, mulch, or leaf litter, making them common inhabitants of gardens, landscapes, and greenhouses inhabitants. They can also invade homes, especially when plant pots harboring them are brought indoors.

These cockroaches are detritivores, feeding on organic matter, including plant material, decaying leaves, and roots. Despite being relatively benign to humans, they can cause damage to plants by feeding on roots and foliage.

Extermination Techniques

  1. Insecticides: A variety of insecticides on the market can be used to control Surinam Cockroach populations. It’s essential to focus on treating areas they are known to harbor, like soil and mulch.
  2. Granular baits: Granular baits can also be an effective solution. These can be spread in infested areas and, when ingested by the cockroach, can lead to death.
  3. Professional pest control: This is more efficient if the infestation is severe. Our professional pest exterminators have access to treatments and can customize an approach to your situation.

Prevention and Management

Preventing an infestation of Surinam Cockroaches includes:

  1. Regular inspection: Regularly inspect areas where these insects are likely to harbor. This includes gardens, landscapes, and greenhouses.
  2. Proper maintenance: Keeping your surroundings clean and well-maintained discourages infestation. Good waste management, avoiding overwatering plants, and composting organic material is beneficial.
  3. Quarantine new plants: If you’re adding new plants to your garden or home, quarantine them first to ensure they’re not harboring unwanted pests.
