The reality of Cockroaches - the insect we associate with uncleaniness

If you are in any sort of area that could be described as coastal or eucalyptus woodland then cockroaches are simply a fact of life.  Unlike mosquitoes, ticks or fleas, roaches aren’t disease vectors, and they do not feed directly on our blood, skin or fluids. We don’t go screaming when we see a mosquito, even though they are the world’s deadliest animal.  Cockroaches have unpredictable movements and phenomenal speed – in relation to their size, they’re one of the fastest terrestrial animals on Earth.

Cockroaches are insects with 6 legs, 3 body parts, 1 pair of antennae and sometimes 2 pairs of wings.  It is important to recognise that each and every insect infinitely help us a lot more than they could ever harm us.    

Australia has more than 400 species of native cockroaches that live in the bush.  Native cockroaches are an important part of the food chain in many natural habitats, being eaten by invertebrates as well as mammals, frogs and reptiles.  Some of the wood eating cockroaches also play an important role as decomposers. Native cockroaches feed in trees on pollen, bark, decomposing wood and leaf material.

If you find a roach in your house, it doesn’t mean it and its family have moved in.  It could have hitched a ride on something such as a grocery bag or newspaper.

In wet weather, they come in where it's dry. In very dry weather, they come in to get water.  If there is moisture and humans (regardless of how clean and vigilant), then there is food.

So if you do see the occasional roach in your room, please capture it and return it to his home.  His family are waiting.
