Cockroaches are known for being one of the most imperishable pests to inhabit planet Earth. Finding long-lasting and cost-efficient solutions for your cockroach infestation problems is rarely a simple task. They often involve an abundance of harsh chemicals, stress for the safety and hygiene of your home or business and require a capacity of time and patience that most people do not have. TMO Pest and Weed Management’s team of experienced technicians are skilled at detecting and managing cockroaches, liberating your home or business of these invasive and seemingly indestructible intruders.

While the presence of roaches in your home may spark panic and disgust, their existence in your family’s space may be a sign of far greater risks and cause for concern. Given the nature of their invasive lifestyle, cockroaches often become travelling hosts to many diseases, such as typhoid, dysentery, tuberculosis, and gastroenteritis. They are capable of spreading various types of food poisoning, making their presence in household kitchens and commercial areas of food preparation and storage particularly concerning. In large populations, cockroaches have been known to bite humans in a defensive nature. Roaches are a triumphant and adaptive group of insects that have changed very minimally since the beginning of their existence millions of years ago. In nature, they can usually be found living under bark, in rotting vegetation, and in the burrows of other animals. Some cockroach species have become masters at exploiting the homes of others, including humans. Our kitchens, drains and sewers equip them with the perfect conditions to populate and survive. A cockroach population will generally seek food, warmth, humidity, shelter and protection or invisibility from predators- especially humans.

Cockroaches are infamous for their resourceful survivalist lifestyle, withstanding even the most inhospitable of natural and man-made environments. These insects can find sufficient nourishment from almost anything, such as animal or vegetable food scraps, pet food, certain fabrics, paper and cardboard, hair, leather, animal carcasses, and even animal waste. Cockroaches boast an impressive breeding ability, with small infestation populating to thousands within a tiny space and timeframe. They are mostly active at night or in darkness, where they gather in large numbers to rest and breed together. They seek the security of contacting surfaces such as cracks and crevices when finding. A suitable place to rest. Unfortunately, such sleep and activity habits can sometimes disguise the severity of infestation in your home or business, and a thorough inspection is often required to locate and exterminate them.

Sighting cockroaches during daylight hours or in well-lit areas indicates that there may be an overpopulation of the insect in your space, and further investigation should be carried out to locate their usual resting places. The most common cockroach species in Perth are:

  • German Cockroaches
  • American Cockroaches
  • Native Australian Black Cockroaches
  • Brown Banded Cockroaches

German Cockroaches Treatment Perth


German cockroaches are a smaller species of cockroach usually only measuring 13 to 16mm in length by adulthood. They are a light-tan to dark-brown colour. These small but agile cockroaches prefer warm and humid temperatures, and are most drawn to dark, well-hidden environments. Their nests and breeding hubs are usually found within drainage networks and other underground structures such as sewers. They are commonly found wherever food is stored and prepared, making your kitchen a likely harbouring area. Typically, given their smaller size, they can move faster than other cockroach species on horizontal and vertical surfaces. The risks associated with German cockroaches are essentially the same as other, larger breeds. German Cockroaches spread bacteria as they walk, transferring harmful pathogens like salmonella and E.coli to every area they come in contact with. Cockroaches also shed cuticles, faeces and other cockroach debris which are known asthma and allergy triggers. While they may not appear as sinister or damaging due to their size, their increased activity and speed allows them to cover more area, spreading their associated bacteria at a higher rate.

American Cockroaches Treatment Perth


The American cockroach is the largest of the cockroach species. Their adult bodies can reach a length of 30 to 50mm in length. Visually, they are distinguishable by their yellowish band behind the head and reddish-brown colour. American cockroaches populate in warm, moist, and dark conditions. In colder regions, or winter months, these cockroaches tend to adapt to indoor nests, but mainly live outdoors in warmer conditions. Like their German cousins, American cockroaches prefer to spend their daytime hours protected in warm, dark, and moist locations, such as sewers, inside walls, roofs and beneath subfloor voids. They often gather around hot water pipes, fridge motors and other heating appliances. The American cockroach prefers to feed on decaying, organic matter, but will feed on a wide variety of plant and animal material. These large roaches can fly when needed and are attracted to lights. They can often be seen around stormwater drains. Ordinarily, the female roach’s life span can reach up to two years, and adult American cockroaches have been known to survive for several months without food or a water source.  Under ideal environmental conditions, American cockroaches can breed with immense efficiency, producing mass offspring that can very quickly become a major infestation issue in your home.

Native Australian Black Cockroaches Treatment Perth


The Native Australian Black cockroach is commonly found indoors during the warmer, summer months. Like their name suggests, they are black with white stripes on both sides. These native insects can grow to 35mm in length and are wingless, meaning they cannot fly like their American counterparts. This cockroach is primarily a species that thrives outdoors amongst nature. They are a scavenger insect, and feed on decaying plant material. Of all the common cockroach species that may infest your home or business, the Native Australian Black cockroach is not a recognised carrier of disease, largely due to its preference for leaf litter over human leftovers. It is often found to be an invasive species in your home over the summer period, as they venture inside properties seeking shelter from the intense Western Australian heat.

Brown Banded Cockroaches Treatment Perth


The Brown Banded Cockroach is another small species of roach that can be found inside your home. They are pale brown in colour, with noticeable light bands that run across the insects’ thorax and abdomen. Unlike the other cockroach species, the Brown Banded cockroach can live in in extremely water-deprived environments. They may be active throughout the entirety of your home or building, not just the kitchen and other damp areas. They have been known to find a suitable home inside modern technology and can be found deep within electrical equipment such as computers, keyboards, microwave ovens. The brown banded cockroach may fly if disturbed by predators, so effective treatment and location is best left to professional technicians.
