For centuries, cockroach outbreaks have been feared for several reasons:

They damage to packaging, belongings and furniture

Cockroaches have sharp teeth and strong jaws that are capable of chewing through a wide range of organic and inorganic materials, including plastic. Look for unusual signs of damage in unexpected places, not just on food packaging. This can include leather goods, clothing, furniture and books.

They continue to attract more cockroaches

Cockroach droppings can emit a pheromone to entice more cockroaches to the same area. To make matters worse, when droppings continually accumulate at their nesting site or aggregation point, a small issue can quickly turn into a big outbreak.

They trigger allergies

A runny nose, itchy eyes or throat, or persistent cough, can be symptoms of a cockroach allergy. These arise after being around their droppings, saliva or shed skin. Sometimes, the droppings also contain various allergy triggers, including parasitic worm eggs.

They spread disease

Due to their unhygienic feeding and nesting habits, cockroaches can accumulate a range of highly infectious bacteria, parasites and viruses, which they leave behind on food, objects and surfaces where they feed, nest and crawl, resulting in contamination. Once you come into contact with something that is contaminated, you are at risk of being infected and falling ill. Some diseases spread by cockroaches include:

• Diarrhoea
• Gastroenteritis or food poisoning: caused by salmonella, campylobacteria, listeria, e. coli
• Typhoid fever
• Cholera
• Dysentery
• Leprosy
• Hepatitis A

Identifying the species of cockroach causing an infestation can make it easier to treat the problem by understanding their habits and behaviour. Here are the most common types found in Australian homes and businesses:

American cockroach

• 35-40mm long and have a glossy reddish brown colour
• Capable of running and using their wings to fly at high temperatures
• Live in trees surrounding your property
• Favour humid climates and also darker, less frequented areas in buildings, including roof cavities, basements, subfloors, kitchens and bathrooms

German cockroach

• Grow to 12-15mm long, easily identified by 2 dark stripes along their head
• Skilled at climbing
• Live indoors, in warmer, humid climates with moisture, usually found in wet areas such as the bathroom, laundry and kitchen

Australian cockroach

• 23-35cm long, with pale stripes on their wing and near the head
• Prefer living in areas with mild winters
• Hide in gardens and debris
• Enter buildings at night

Cockroaches are naturally attracted to places that provide good shelter and nesting sites, as well as an abundance of food sources. If left unchecked, an outbreak affects cleanliness and hygiene, creates an unpleasant odour, and spreads disease. This will eventually lead to staff, contractors and customers falling sick and being reluctant to return, a loss of stock and trade, and damage your reputation. To top it off, in Adelaide you can also cop heavy penalties for breaching food and industrial health and safety standards.

Restaurants
An abundance of fresh food makes restaurants vulnerable to a cockroach outbreak, and the results can be disastrous. A cockroach sighting can ruin your reputation overnight and subject you to fines for breaching food safety laws. If left unchecked, a colony can quickly spread diseases over chairs, tables, crockery and equipment, and cost you dearly in damaged stock. To prevent an outbreak, all restaurants must practice proper storage of food supplies, stock and rubbish, and implement regular pest control to meet regulatory requirements.

Commercial buildings
A cockroach problem for one tenant can potentially become an issue for all tenants in the building, so it’s important for everyone to follow the same strict health and safety practices. You may even experience disruptions to trade while the outbreak is being treated.

Distribution facilities and warehouses
The sight of cockroaches scurrying around is not just distracting and off-putting to workers. Cockroach germs can contaminate stock and machinery,, and make you liable for not meeting WH&S obligations. Cockroaches may even be transported to other locations by latching onto products loaded for transport.

There are several ways to manage a cockroach infestation, and using more than one give you the best chance of success. Here are some common methods used in Adelaide:

Cockroach bait
This is effective for use indoors, and comes in liquid, gel and solid form. Baits are strategically placed close to nesting areas and the poison is transferred from an affected cockroach to the rest of the colony.

Fumigation
This method is effective for more serious infestations in a confined space, and best used alongside other methods. A gas containing insecticide chemicals is introduced to a building that has been sealed off.

Heat treatment
This method is the most environmentally friendly and chemical free, and can prevente cockroaches at any stage of their life cycle. A mobile system delivers dry heat of 50-60 degrees to an area for a monitored period.
