How to eradicate Cockroaches

 Eradicating Cockroaches from your home or commercial premises.

If you’ve discovered a cockroach infestation, at your home or business, then simply follow our guide for  successful eradication below.

STEP 1

1-Thoroughly inspect the property and determine the areas where cockroaches are present. Take note of droppings, and staining to walls and/cupboards, as these can indicate areas of high infestation. Remove all sources of food, including waste, stored food products and water where possible. Ensure that stored food products are in sealed containers.

STEP 2

Identify the cockroach species for the most successful treatment. While there are many varieties which may invade your property, the two main treatment methods will be determined by whether you have ‘German Cockroaches’, or basically any other variety. German Cockroaches are a light brown to amber with 2 longitudinal stripes on what looks to be the back of the head. Smaller than our native varieties, adults are between 12-15mm in length.

Product Choice

In the past German cockroaches were notoriously difficult to control, and multiple products were commonly required as their reproduction is much faster than other varieties. However since the launch of Clearout Crawling Insect Spray containing Fipronil and Seclira WSG containing Dinotefuran when combined with Gel baits the results have been outstanding. The most effective gel baits for German Cockroaches will contain Fipronil Clearout Cockroach Gel bait (Brown formula) & Goliath Cockroach Bait, however our goto product is the new white colour gel Clearout Commercial Cockroach Bait as it does not leave any unsightly mess and is highly attractive.

STEP 3: Treatment 

FLUSH & KILL - Flushing the cockroaches out of their harborage is the key to identifying where they are. The use of a non repellent aerosol Clearout Crawling Insect Spray is our choice. Apply Clearout into cracks and crevices such as commercial trolley or table rollicks and across treated surfaces. Much of the activity will die soon after, but there will be some survivors who you may not have been able to contact with the aerosol.

LIQUID BAND SPRAY - Apply Seclira WSG which is a clear liquid when diluted and has a fast knockdown and kill. Apply to skirting boards as a band spray in kitchens and food harborage areas.

GEL BAIT - For the remaining cockroaches (small nymphs) and cockroaches that remain, apply gel to the inside of cupboards and sensitive areas where liquids and aerosols could not be applied. 

FOLLOWUP INSPECTION - .After a period of approximately 10 days, the results of your treatment should be evident. Activity should be almost at a standstill. If not, then an additional treatment may be required with a repeat of the same process as before.  Cleanliness of the property is the key as you want to limit the amount of available food source as much as possible to prevent any remaining activity from having a feed on tap.

OTHER COCKROACH VARIETIES AND TREATMENT

1-Identify key harborage areas and potential food sources.

2-Apply an approved liquid chemical as a light spray to the skirting boards and kicks around a desired area or property. Chemicals such as Deltamethrin are popular and economically viable.

3-Apply an approved gel bait to all cupboard door hinges and pipework. A common reference is 500mm spacings for domestic jobs and 300mm spacings for commercial work.

4-Thoroughly dust all cracks and crevices about the property, focusing on areas with a source of heat such as electrical and cooking appliances. Wall cavities and accessible ceiling spaces included. (A suitable product is a non repellent in Fipforce DUST(A light dust is all that is required).

5-Flushing Aerosols such as Chaindrite Extra Aerosol  or Py spray Aerosol are also a great tools for blasting hidden cockroaches out into the open and across treated areas.

EXTERIOR COCKROACH CONTROL 

Exterior perimeter treatments are also recommended to help reduce the numbers in close proximity to the property. Perimeter liquid treatments and dust applications to exterior weep holes and access points are recommended.

 

While the processes are much the same, German Cockroaches are far more difficult to control, so thorough treatment and application of products to the correct locations is essential.

When treating German Cockroaches, if you imagine that you must physically contact each and every live cockroach with some form or treatment product during the treatment, then you will have a good chance of gaining control of the infestation.

With other species, residual products work better and they are susceptible to picking the products up on themselves and having it ingested while preening.

ABOUT COCKROACHES

Cockroaches are the most common household pest. They have infested our homes, shops, restaurants, café’s ships and even cars for years. They feed on organic matter such as human food waste, sewer and other animal waste, and are well known to spread disease.

Places where crumbs and stored foods/food preparation areas are located often provide ideal conditions for breeding and harborage, which brings them into our lives. Transported in cardboard corrugations, boxes provide a ready source of infestation when food is delivered to homes and commercial restaurants and other food service facilities.

One of the hardiest creatures on Earth, they have been around for millions of years and are likely to be around after humans have vacated.

 

COCKROACH SPECIES

In Australia we have over 400 native species of cockroaches with 6 main pest species. Cockroaches where introduced to Australia 200 years ago and are now the most common household pest.

 

Commonly found species are:

German Cockroaches

Australian Cockroaches

American Cockroaches

Smokey Brown Cockroaches

Brownbanded Cockroaches

Oriental Cockroaches

 

While we are unable to completely eradicate the presence of cockroaches, we simply must manage our property in a manner that keeps them from setting up shop. Keeping kitchens and bathrooms dry and clean, and having all food sources sealed will help to prevent most significant infestations.
