Cockroaches can and do pose a severe health risk to humans.
With their ability to crawl into cupboards, drawers and pantrys in the home, they spread diseases such as food poisoning, salmonella and dysentery.
They are scavengers by nature and will eat a variety of substances.
Cockroaches are mostly found in food preparation areas and warm, dark moist places such as under bench tops and drains.
Their sizes range from tiny to over 10cm in length, but in a lifetime, a femal cockroach can lay around 240 eggs, which means that ignoring the problem will only result in large numbers of cockroaches being born.
A schedule of regular maintenance will help to control these insects, and when combined with proper storage of food products, can reduce the concern of cockroach infestation.
If you have roaches, chances are, you will need a professional. In a cockroach control program, we begin by thoroughly inspecting the premises. In our inspection we find the areas where the roaches are hiding. We schedule a time to come back and treat those areas where the roaches hide with insecticides, including baits and insect growth regulators. It is necessary for some time to monitor the situation and to treat as necessary. Cockroaches are elusive and they reproduce very quickly, especially the German cockroach.
There is a lot that the homeowner or tenant in a house with a cockroach problem can do to help with control measures. Sanitation is crucial. As much as possible, the roaches need to be denied food, water and places to hide. These measures are a necessary part of any roach control program:
- Store your food properly: Keep food in containers that close tightly and cannot be chewed through by roaches. Cardboard and paper are not roach proof. Rubbermaid and mason jars probably are.
- Clean consistently and thoroughly. Concentrate on areas where grease accumulates, such as ovens, stoves, drains and vents.
- Remove stored items that are not necessary, especially boxes and bags which provide a perfect hiding place for roaches.
- Keep your garbage in a covered garbage can which can be snapped down firmly after something has been put into it.
- Caulk cracks where the roaches can hide. The adult German cockroach can fit in a crack as narrow as 1/16 of an inch. Plugging up these hiding places reduces the carrying capacity of your home for cockroaches.
- Denying the roaches water can be harder, but some things can be done. Repair any leaky pipes and faucets, put the pet’s water dish away at night, ventilate moist areas, and do anything else that you can think of to make water hard to find for the cockroaches.
30-35mm in length. Dark Brown/Black in colour.
These cockroaches are more easily defined in colour as they have distinct yellow/white markings down the sides of the wings. Found in gardens and subfloor areas.
German cockroaches are about 1cm long when they are fully grown and a light brown to tan color. They have two dark parallel lines on the area just behind the head. German cockroaches are the most common household pest in the Australia. They can increase their numbers very quickly and can therefore be hard to control. It is usually necessary to hire a professional to take care of such a problem through a complete cockroach control program.
The American cockroach is the largest common species in the Australia. It grows to 3.8cm or more in length. It is reddish brown and has a brown or yellow border near the head. American roaches are not common in homes. They prefer warm damp locations such as steam tunnels and boiler rooms. They do fly, and can migrate from building to building.
