Commercial Cockroach Control Perth

Insect Control PerthCockroaches are one of the most common pests in commercial businesses. They tend to favour conditions similar to those that humans create, which is why effective insect control in Perth is so crucial.

Cockroaches can contaminate food, utensils and preparation areas with droppings, vomit and cast skins. A study in 2005 in the US shows that cockroach allergens appear to worsen asthma symptoms more than any other known trigger. Additionally wherever a cockroach infestation occurs it is usually accompanied with a foul odour. The odour is caused by their droppings, vomit and bodily secretions.

Current legislation requires all food businesses to provide a kitchen free of pests. An easy way to do this is for Allpest to provide you with a Foodsafe, HACCP and AQIS compliant cockroach control program.

Cockroach Information


The cockroach is exceedingly hardy and has a tremendous capacity to produce offspring. Cockroaches have adapted to living with people and need four things to survive:- water, food, shelter and warmth.

German cockroaches gather in warm, humid, dark places near food and water. Cockroaches often live in cracks and crevices so small we can easily overlook them. They like porous surfaces like wood, paper or cardboard over non-porous surfaces like metal. Cockroaches mark these surfaces with a pheremone found in their faeces. This pheremone attracts other cockroaches, especially the tiny, immature ones who will stay there until they are larger. German cockroaches have a high water requirement and are most likely to be found in kitchens and bathrooms, gathering in the cracks and crevices of counter tops, in wooden cabinets, in wall and ceiling  voids, in and around refrigerators, dishwashers, stoves, washers, dryers and water heaters. If food, water and shelter are available, the cockroach population can multiply rapidly when temperatures are warm.

A female German cockroach  produces an egg case containing 30-40 eggs. The female carries this egg case for approximately 3 weeks until the day the eggs hatch. The immature cockroaches (nymphs) grow fast when conditions are favourable. Nymphs will shed their skins six or seven times in about 60 days. After the last moult, adult cockroaches emerge fully winged and sexually mature. The female German cockroach con produce as many as eight egg cases and more than 300 offspring.

Essential Cockroach Resources

Water - Cockroaches have a waxy coating on their body to prevent moisture loss, but they still need water. One drop of water per day is all a cockroach needs. Any moisture will do - condensation on pipes, small leaks, moist sponges, soaked wood or moistened food.

Food - Cockroaches eat almost anything: crumbs, hair, fingernail clippings, spots of grease, soiled clothes, pet fur and dead insects. Very small cockroaches stay in hiding places and eat the droppings of the older cockroaches.

Shelter - Cockroaches live in cracks and crevices during the day. They prefer wood and paper over metal surfaces. Cockroaches can squeeze in to cracks 1/6 inch or larger. Cockroaches like warmth produced by electric motors, condensers and ovens and may live inside appliances, especially if there is water nearby.

Problems Associated with Cockroaches

Cockroaches may become pests in homes, schools, restaurants, hospitals, warehouses, offices and virtually any structure that has food preparation or storage areas. They contaminate food and eating utensils, destroy fabric and paper products, and impart stains and unpleasant odours to surfaces they contact.

Cockroaches may transmit bacteria that cause food poisoning and are believed to be capable of transmitting disease-causing organisms. They have also been implicated in the spread of typhoid and dysentery. Indoor infestations of cockroaches are an important source of allergens and pose a risk for asthma among some populations.


Managing cockroaches is not easy. You must first determine where they are located. The more hiding places you locate and manage, the more successful your control program will be. 

Monitoring cockroaches - You can identify the areas of infestation and know where to concentrate control efforts by placing traps in several locations and inspecting them regularly. You can also track a cockroach infestation by using a flash light to inspect cracks, underneath counters, around water heaters, and in other dark locations.

Sanitation - Store food in insect-proof containers. Keep garbage and trash in containers with tight-fitting lids and use liners. Eliminate plumbing leaks and correct other sources of free moisture. Vacuum cracks and crevices to remove food and debris. Remove trash and stored items from around the building.

Limit access - Seal cracks and other openings to the outside. Use weather stripping on doors and windows. Look for other methods of entry, such as from items being brought in the building especially appliances, furniture and items that were recently in storage. Inspect food deliveries before putting them in to the kitchen. Look for egg cases glued to the undersides of furniture, in refrigerator and appliance motors, boxes and other items. Locate and seal cracks inside the treatment area where cockroaches can hide. Trim shrubbery around buildings to increase light and air ventilation. 

Pest Control - Cockroach control in Perth is usually achieved via a combination of insecticidal dust, residual spray, aerosols and gel bait.
