Why Cockroaches are a pest?

Cockroaches that share cohabitation with humans are considered pests as they are known to transmit diseases and other various reasons below:-

1. Contamination - contaminate food products and utensils with their droppings, casts, skins, empty egg cases, dead cockroaches and vomit markings.

2. Fear reaction - people are scared or annoyed by the presence of cockroaches. Cockroaches have quick unpredictable movements when trying to avoid them. Also if they touch you with their spiky legs. 

3. Odour - when there is an infestation of cockroaches an terrible odour may develop, which is from the cockroaches secretions from the mouth and cuticles.

4. Allergic reaction - some people are allergic to cockroaches. They may get skin reactions or have asthma attacks. 

5. Bites - cockroaches have been known to bite people, although this is rare. When infestation is considerably high it has been know to happen on ships. Sailors have suffered bites, gnawing of fingernails, toenails, calloused parts and soft skin.

What unusual habits do Cockroaches have?

Cockroaches infest buildings and other structures as long as they have food, shelter and preferable temperature and humidity. Cockroaches can live in groups of 100s and 1000s. Individuals are easily transported to other places in food, food packaging, luggage, furniture, buses, trains, ships and aeroplanes. Listed are other interesting habits of cockroaches:-

Omnivorous - eat anything and are very efficient scavengers. They eat animal and human food, dead animals or vegetable material, leather, cardboard, fabrics, hair, glue, wallpaper glue, starchy bindings in books. They can survive by eating droplets of grease and small crumbs so thorough cleaning is essential in a cockroach control program.

Nocturnal - they hide in when it is light and are active when it is dark. They emerge to seek for food. Active cockroaches observed during daylight hours often indicates an overpopulation. 

Thigmotactic - they rest in tight cracks and crevices with the security of contacting surfaces above, below and around them.

Gregarious - adult and young cockroaches congregate and rest together. In extreme overcrowding they will be a mass migration of cockroaches happening.

Grooming - they frequently groom themselves. Grooming consists of running the antennae and legs through mouthparts with a nibbling action. 

How do Cockroaches reproduce?
Life Cycle of an American Cockroach

Cockroaches reproduce sexually. The female leaves an attractant pheromone. The male detects the scent through his antennae. They will mate end to end. Eggs develop in the female, then they are encapsulated in a purse shaped egg casing called the ootheca. Oothecae may contain 12 to 40 eggs. The egg case is either dropped or glued to the surface just prior to or moths before hatching. After hatching, the nymphs tend to congregate with the adults, they live in close proximity to each other and are extremely social with each other. Nymphs moult various times and can take 2 months to over a year to gain adulthood. Adults lifespan can be a few months to a year. A female adult can produce 5-30 oothecae. All development time frames depends on the species of cockroach involved. 

German Cockroach
German Cockroach

Normally found - internally near warm areas such as fridge motors, microwaves, toasters, ovens and other electrical appliances. Also under sinks and cupboards, in and under drawers.

Recommended Treatments - normally rely on the use of a flushing agent to main harbourages coupled with gel baiting application to eliminate colony

General Information -  is known worldwide because it coexists with humans in their buildings. Its small size allows it to sore away in small cracks and cervices, together with its abundant breeding capabilities allows it to build up large populations in a short period of time. Efforts aimed at controlling this most successful scavenger must be regularly and constantly made.

Appearance - is relatively small cockroach. Adults are light amber-brown, with two dark longitudinal stripes on the pronotum. The pronotum is the middle section of the body of an insect between the head and the abdomen, bearing the legs and wings. The adult has wings but they only use them to flutter to the floor if brushed from a wall or ceiling.

Breeding - it is the most fertile breeder of all the pest cockroaches, taking only 40 days to go from egg to adullthood. Egg cases of 30-40 are carried by the female until hatching

Habitat -  seeks an environment that provides warth, moisture and food. They find cracks and crevices in buildings mainly kitchen in which they can hide during the day, If they are found out in the day time or in other areas besides the kitchen then it is highly likely that the building is supporting an enormous population of German Cockroaches. Infestations are common in food handling areas, factories, warhouses, storerooms, restaurants, clubs, hotels, hospitals, food bars, domestic kitchen and catering or canteen areas of office blocks, schools nursing homes and any building with a kitchen.

Food Source -  will eat almost all organic material found in food handling areas. From crumbs to build up grease. If there is a water source then the adult cockroach can survive without food for at least a month.

American Cockroach
American Cockroach

Normally found - in roof voids, drains and sewers

Recommended Treatments - repair leaking drains. Apply liquid chemical spray and chemical dust both have a flushing agent and will kill locally present cockroaches and minimise re-infestation due to the residual effect of chemical

General Information -  infests dwellings and utilities. If is a worldwide traveller as it can glue its egg cases to food packages, boxes and pallets. The largest pest cockroach.

Appearance - Adults are red-brown in colour with a pale yellow border around the pronotum. The pronotum is the middle section of the body of an insect, between the head and the abdomen, bearing the legs and wings. It like to fly in warm weather for relatively short distances.

Breeding - the female produce up to 50 egg cases in their lifetime. Adults live 6-12 months. Egg cases have up to 16 eggs in a case. When the nymphs hatch they take 6-12 months to develop into adults. Thus the entire life cycle of an American Cockroach is 1 to 2 years.


Habitat - in warm climates likes to live outside but in colder climates they rather to go indoors. When indoors they do not dwell where we do but prefer to live in the walls, roof and subfloor voids and in and around sewers, drains, moist cellars, grease traps and rubbish dumps, infestation is common in hospitals, bakeries, food stores, warehouses, factories and domestic residence.

Food Source - likes to eat decaying organic matter but it also will east human and animal foods, book bindings, paper, clothing. If there is a water source then the adult cockroach can survive without food for at least 2-3 months.

Smokey Brown Cockroach
Smokey Brown Cockroach

Normally found - in timber fences and wood piles

Recommended Treatments - liquid chemical spray

General Information - has a similar life story to the American Cockroach

Appearance - relatively large cockroach. The adults are dark brown to almost black with no pale markings. It is fully winged and can fly short distances in warm weather and will fly to lights at night time.

Breeding - the females produce up to 26 eggs in a case and can lay 20 cases in a lifetime. When nymphs hatch they take 6-12 months to develop into adults. Adults live 6-12 months. thus the complete lifespan is between 1-2 years.


Habitat -  is an outdoor pest and very seldom does it infest dwelling parts of buildings. It sometimes is found in garages, sheds, subfloor areas, roof voids and in and around grease traps and drains. It however is mainly found in green houses, nurseries and gardens.

Food Source - is very particular with its food and likes to eat plants.

Oriental Cockroach
Oriental Cockroach

Normally found - in most dark areas

Recommended Treatments - remove moisture. Then apply liquid chemical spray and chemical dust formulation both have flushing agents and will kill locally present cockroaches and minimise infestation due to the residual effect of the chemical

General Information - is a major pest in British buildings

Appearance - is a medium sized cockroach. They are dark brown to black in colour. The male wings cover most of the abdomen whereas the female wings are much smaller.

Breeding - the females produce up to 16 eggs in a case and lay 14 cases in its lifespan. When the nymphs hatch they take 6-18 months to develop into adults. Adults live 3-6 months. Thus the complete lifespan is between 9 months to 2 years.


Habitat - likes cooler climates and are more a pest in the southern area of Australia. It is commonly found outdoors under leaf litter and bark, in damp subfloors and around drainage systems

Recommended Treatments - remove any possible water sources. Apply liquid chemical and dust formulations to known harbourages.

General Information - are very active and like to live everywhere within a dwelling

Appearance - is a relatively small cockroach. The adults are pale brown in colour with a pale band across the thorax and abdomen. The males have large wings that go past the abdomen, whereas the females wings are shorter.

In domestic dwellings it can be found in wardrobes, dressers, cabinets and behind bookcases or wallpaper. Its activity is scattered throughout a building rather than being only in kitchen areas like the German Cockroach. They both like warm temperatures but Brownbanded Cockroaches don't need as much moisture.

Food Source - eats anything that is available to them.

science lab testing for diseases
Do Cockroaches carry diseases?

Yes, cockroaches have not been irrefutably proven to transmit diseases to humans, several factors point  to the likelihood that they play an important role in disease transmission.

1. Dwell in environments that support  the growth of organisms causing diseases such as sewers, grease traps, polluted water

2. Contact on various surfaces (including food) in kitchens and food processing places 


Australian Cockroach
Australian Cockroach

Normally found - in gardens and subfloor areas

Recommended Treatments - remove any possible water sources. Apply liquid chemical and dust formation to know harbourage areas.

Appearance - is a relatively large cockroach. It has a dark brown body with a clear yellow marking on the pronotum.
