Can You Ever Completely Get Rid Of Cockroaches?

Cockroaches are common pests in Australian homes. While there are many temporary methods to kill roaches, most homeowners want to know whether they can completely get rid of them forever. There are many ways to overcome the problem for a short period of time, but you will eventually need the assistance of a professional Pest control Sydney service to achieve this objective. This guide provides you with helpful insights into this topic.

Natural Ways to Kill Cockroaches

Here are some natural methods to get rid of roaches:

i. Diatomaceous Earth (DE)

Diatomaceous earth (DE) is an effective natural cockroach killer. It works by sticking to the pest’s legs, dehydrating them, and its sharpness also causes damage to their exoskeleton. It is a proven natural insecticide and features pulverized and fossilized algae. You can use food-grade DE and sprinkle it on a surface where there is high cockroach activity. 

It is further recommended to mix boric acid and borax with DE to achieve a more comprehensive effect and result. These treatments require proper placement and repetitive application to achieve effective results.

ii. Baking Soda

When cockroaches consume too much baking soda, it can prove to be toxic. You can encourage these pests to eat it by mixing it with sugar. Leave the mixture out in the open. Most kitchens have baking soda and this is a simple strategy. The non-toxic and affordable product works by producing gases inside the pest, causing it to die. You can also use Epsom salt in place of baking soda.

iii.  Lemon

Lemon and its citrus content act as a good repellent to roaches. It works by creating a scent that deters these pests. The simplest way to force cockroaches is to add a few drops of lemon oil to water and use it to mop the floors. This is a safe, affordable, and effective way to get rid of roaches. 

Professional Pest Control Services

If you want to completely get rid of cockroaches, it is recommended to get the help of a professional Pest control service. A professional service can create a program to kill any existing roaches and prevent any from entering your home. Some of the key features of such a program are as follows:


The licensed experts will inspect the existing infestation. They will look for the following factors:

  • Areas that allow roaches access to your home
  • Sources of food
  • Sources of moisture
  • Species of cockroach

Once the inspection is complete, they will create a customised plan for effective treatment.

Initial Treatment

Cockroaches are among the most difficult pests to get rid of. Just like a Mice Control Sydney program, a 2-step process may be required to remove these pests. The types of treatments can include:

  • Monitoring
  • Baiting
  • Trapping
  • Spraying
  • Cleaning & sanitization


A professional doesn’t just end with a single treatment. The experts will check the results of the application and deploy more treatments based on the requirement. This helps end the infestation within the shortest possible time.

So, if you seek a complete removal of cockroaches from your home, it is recommended to seek professional help. This means that periodic inspections and treatments will be required after the initial application.
