Here are a few tips to keep your home or office cockroach free – 

  • Seal all cracks and crevices in your property’s indoor and outdoor areas to avoid cockroaches from entering.
  • Ensure the drains are unclogged at all times. 
  • Fix leakages
  • Clean your dirty dishes and avoid leaving them in the sink overnight.

How To Know If Your Property Has Cockroach Infestation?

You can judge the presence of cockroaches by looking at signs like:

Roach Dropping: 

Black in colour, roach droppings resemble ground coffee.

Smear Marks:

In places where water is accumulated, the roaches produce irregular shaped brown smear marks. These marks form as they rest or crawl from one point to another. 

Egg Capsules:

Roaches lay eggs in a capsule known as ootheca. Every ootheca contains many eggs. These egg capsules are primarily found in damp and dark places.

Shed Skin: 

Cockroaches shed their skin at least 6 to 7 times in a lifetime. This happens when they are transforming into an adult. You may spot skin dropping in your property’s damp and dark areas. 

Unusual Odour:

Cockroaches produce a pheromone when they defecate in their sleep. This attracts more roaches and exudes a musky odour.

Live Cockroaches: 

You may see live cockroaches moving in your kitchen, near your wardrobe, in the basement, or any other place that is dark and damp.


Cockroach Treatment in New Zealand

When you hire the experts at Tom’s Pest Control, we inspect your property first to understand the level of infestation and the type of cockroaches living. Depending on our findings, we may adopt any of the following treatments:

Cockroach Bait

Cockroach baits are available in solid, liquid and gel forms. Depending on the level of infestation, we may decide which type of bait is best for your property. We place the baits in areas that we feel are the most accessible to the cockroaches. Once they consume the bait, they may go back to their colony and defecate, thus killing other cockroaches. Therefore, the bait system is one of the most effective ways to remove and control the cockroach population.



This treatment uses insecticides for the effective removal of cockroaches. This treatment is a gas exterminator that is ideal for use in commercial spaces like warehouses, manufacturing houses, stores, etc.

Heat Treatment

If you want us to carry out a chemical-free treatment, you may ask us about the heat treatment. As its name suggests, this treatment involves the application of heat to kill cockroaches and their eggs.

These are just a few treatments that we carry out to remove cockroaches. Sometimes we may have to use a combination of treatments to get you the best results. Depending on the level of infestation on your property, we prepare a customised treatment plan for you.

Is there an American cockroach in Australia?

The most common Australian cockroach type is the German cockroach.


The American cockroach can infest other buildings. American cockroaches are commonly known as the “Palmetto Bug”. The “Palmetto Bug”, as it is often called, lives in trees. It is attracted to dark, damp, and unperturbed environments.


Basements, baths, and subfloors are common places to find them. American cockroaches are 35-40mm long and have a gleaming reddish-brown colour. Male wings are larger than female wings, which barely touch their abdomens.

How do I get rid of German Roaches quickly?

To prevent roach reproduction, an insect growth regulator is required. All mature German Roaches are killed by Invict Gold.


Anyone who has previously used the German Roach Spray Kit will be able to use it again. Tekko Pro IGR and Alpine WSG insecticides are included in this insecticide mixture. However, they won’t be able to stand it (Insect growth Regulation). Spray the liquid mixture into cracks and crevices first. Then, spray the surface with Shockwave aerosol to kill the roaches.


As a long-term solution, we recommend Avert Flowable bait. It is extremely durable and can be used for many years. It can also be used as bait or tracker. The powdered bait can also be used to lure and track roaches. This bait should not go in cracks, crevices, or under appliances. Gel baits are also available for flat surfaces.

Is there a safe temperature at which German cockroaches can be killed?

German cockroaches may die if they are left to heat at 45F for more than 10 hours. They can also die from the heat below 14 degrees F.


Cockroaches can’t regulate their body temperature after exposure to temperatures up to 50 degrees. As a result, they die when exposed to temperatures they do not like.


Different species of cockroaches can survive with different survival rates. They can survive at just the right temperature. However, they will die if exposed to too much heat, too little cold, or both. They can be frozen but not heated.
