When a client calls me, I go through my usually spiel of what their property is like and what pests they have.


When asking if a client has German cockroaches, some don’t know the difference as a cockroach is a cockroach and they just want that damn cockroach gone and dusted out of their home.


So, what does a German cockroach look like?

Help, how to get rid of German cockroaches?


Unfortunately, German cockroaches are imported into your home whether you bought a box or bag inside that may have had a live German cockroach or the Ootheca (egg casing).


If you live in residential apartments they can travel between units when infestations occur.


All you need in one ootheca to start an infestation forming in your property. For every female German cockroach, she will have roughly forty to fifty baby cockroaches and before you know it an infestation of German cockroaches can get out of hand.


What do German cockroaches eat?


German cockroaches love when we don’t wipe down our tables, benchtops and stove tops, they will feast on just about anything and everything when we don’t clean up each day.


That being said, German cockroaches will also feast on paper, electrical appliances. Toothpaste, soap, dead cockroaches and bugs.


When are German cockroaches most active?


They are a nocturnal insect and will usually come out of their harbourage spots at night-time once everything has settled down for the night. If you are seeing German cockroaches in the day it is an indication that you have a high infestation of German cockroaches and a treatment is need ASAP.

  • Cleaning of the kitchen is a must. Wipe down all surfaces such as benchtops and stove tops, moping, a good clean behind the fridge, wipe out the microwave and dishwasher.
  • Remove all clutter such as papers, boxes and plastic bags, to minimise anywhere German cockroaches can hide and breed.
  • If the problem exists outside of your kitchen you will need to make sure that a through clean is taken care of and all clutter is removed as this is the perfect breeding ground for German cockroaches to breed and explode with an infestation.
