Australian Cockroach control and Facts

australian cockroach

 

Despite their name, they are not native to Australia. They originated from Asia.

They became totally adapted to the domestic life. They are pest in households.

This species of cockroach, and the German Cockroach, have given the Cockroach group the bad name.

They transmitted diseases when they occur in house and restaurants.

They can contaminate food and must be controlled.

They have long spiny legs, their antennae are longer than their body..

Characteristics of Australian Cockroach:

Size 30-35mm  
Shape oval  
Color Yellow border on pronotum (area behind the head) is very distinct.Dark Reddish brown in colour.  
Legs 6  
Wings yes  
Nymph similar to adult but wingless  

Diet

Omnivorous. Scavenger. Prefers decaying organic vegetable matter. Will feed on starch materials such as book bindings..
Life cycle

Gradual / Incomplete metamorphosis (egg – nymph – adult). Eggs are encased in an egg capsule (Ootheca). Female drops the egg capsule (Ootheca) shortly after it is formed near a food source, in crevices, on walls, or under workable material such as moist wood, so as to camouflage it.

Eggs per capsule: 16-24.

Incubation period: 30-40 days.

Nymphal period: 6-12 months.

Nymphs normally moult 10-12 times to reach adulthood. Females may produce 12-30 egg capsules in a lifetime. Egg capsules are completed and dropped at about 10 day intervals. Adult lifespan: up to 8 months.

Habitat

Found mostly outdoors. Often found under bark of trees, woodpiles and locations with moist and decaying vegetable matter.

Can be found inside homes in cupboards, behind drawers, in all food areas and industrial areas, subfloor areas, wall and roof voids.

Favours warm, humid environments. Is not found as readily in cooler climates compared to the American cockroach.

Damage

Orchid virus transmission by the Australian cockroach. It invades a structure it will feed upon varieties of starchy materials.


Why Cockroach Control must be done?

Presence can cause anxiety or stress.

-Secretions can affect some humans (e.g. allergic reactions such as asthma).

-Dense populations can leave a distinct odour.

Food and utensils can be contaminated with droppings, cast skins, empty egg cases and vomit marks.

A number of pathogenic organisms have been associated with cockroaches.

Their ability to act as vectors of pathogens is still a matter of controversy. This is mainly because that transmission can only occur indirectly via contamination of food and utensils.

Pest status applies equally to nymphs and adults..


Prevention:

* Keep cooking, eating and food storage areas clean and dry. *

Cockroaches have aggregation characteristics which builds a more suitable environment to inhabit.

They favour cracks and crevices for harbourages where they can contact the top and bottom surfaces with their body. They do not leave their harbourages except for food, water and mating.

"Their aggregation characteristic can be used against them, since finding a harbourage will yield more than one individual.

Pheromones are not volatile, so contact with other individuals in the population is necessary, which can help spread insecticide to some degree".

If you see cockroaches, it is best to call a Pest Management Professional - 'James White Ants Destroying' due to the illnesses they can spread.

How To Get Rid of Australian Cockroaches

1.Sanitation

Control should be targetted at their harbourages since they stay in these areas for large amounts of time.

Physical exclusion (e.g. caulking up cracks) is useful since the cockroach population is proportional to the number of harbourages available.

Chemical treatments into cracks and crevices is also valuable since prolonged contact with treated surfaces will yield a high mortality rate.

Applying proper hygiene measures can also be useful, forcing the cockroaches to travel further to find food and water, which increases the chances of contacting treated surfaces outside harbourage areas..

2.Chemical Methods for Cockroach Control

I. Dust

II. Apply a Liquid Residual to the Perimeter

III. Baits & Granules
