How to Prevent and Get Rid of Cockroaches

Cockroaches are attracted by food, moisture and shelter, there are many ways cockroaches get into homes and commercial properties. Cockroaches gain access through open doors and windows however they can also get entry through vents, drain pipes, cracks or they can be brought inside with items for example – inside a box of produce, food or drink. Cockroaches are nocturnal, they are good at hiding and generally come out at night or when things are dark and quiet. Often people don’t realise they have cockroaches until they find the cockroach droppings. In this post we discuss ways to prevent cockroaches and how to get rid of cockroaches.

Habit and Lifestyle of the Australian, American and German Cockroach

The Australian Cockroach female deposits the egg sack containing 16-24 eggs normally near a food source, after hatching nymphs take 6-12 months to develop into adults.  The Australian Cockroach is generally an outdoor cockroach that prefers plant material as a main source of food. They are also found in walls voids, sub floors, garages and sheds.

The American cockroach is one of the largest cockroach to invade our homes and workplace.  The egg sack will contain 12-16 eggs and is carried by the female for several days before being deposited. The eggs hatch in 1–2 months, after hatching nymphs take 6-12 months to develop into adults.  The American cockroach prefers dark, humid and undisturbed areas.  They can be found in subfloors, basements, kitchens, roof voids and bathrooms.  

The German cockroach female carries 35–45 eggs in an egg sack until they are ready to hatch.  The eggs hatch in 1 month and the nymphs take between 6 weeks to 4 months to develop into adults.  German cockroaches are commonly found indoors and like confined spaces.  They like warm, humid conditions and are typically found in kitchens and food handling areas in commercial properties.

How do we get rid of Cockroaches?

Cockroaches find roof voids and wall voids a favourable habourage; the photos below show us having carried out a dusting treatment to the wall void and all the cockroaches picked up a dose and made a hasty exit. As you can see the dead and dying cockroaches that were flushed out their hiding spots.

We cannot stop cockroaches coming into our homes and workplaces looking for food, water and shelter; but our treatment program is designed to target areas where we suspect they will go to hide and in turn they will pick up a dose.
