A mature queen termite can lay up to and over 10,000 eggs a week. Times that by 52 and that’s a lot of termite activity.
Cockroaches
Their insect order is Blattodea and gave rise to the termites over 300 million years ago. A species of cockroaches called the "Oriental Cockroach" (Blatta orientalis) was once a pest species, but is now so rarely encountered it will not be discussed further.
There are five main pest species in Australia, all being introduced and forming less than 1% of all 450 species found in Australia. They comprise of: German, Smoky-brown, American, Australian and Brown-banded.
Pest controllers are often asked by clients "Aren't cockroaches supposed to be one of the cleanest animals because of the grooming habits?" The obviously are not because of the habits of roaming through sewers, urinals, garbage and rubbish. They consume food and faeces of man and animals, harbouring diseases such as Salmonella, Diarrhoea and Typhus.
They are regarded as pests because of a number of factors, some being their characteristic odour, reproductive abilities, contamination of food by their droppings and regurgitations and the spread of diseases.
