German cockroach control: How to Identify, Prevent and Treat
German cockroach control is a big problem here in Australia. They are attracted to warmth and humidity, so it’s understandable they prefer our temperate climate and flourish in summer.
Here are some things to look out for if you suspect you are on the verge of cockroach invasion:
- Cockroaches often shed their skin in areas of the home where they have been residing (usually around food).
- They are very attracted to food, so you are more likely to see signs of them around food scraps or rubbish bins.
- German cockroaches love areas of warmth and moisture, so check under sinks, in and around cooking appliances, and in that cosy laundry room.
- They can’t fly but they are good climbers, so check in high up places such as storage areas or on the roof.
- Cockroach droppings are black and only small, a clear sign of a bigger roach problem.
German cockroaches are the small baby-like roaches that you will find hiding in your pantry, car, and laundry and, in fact, anywhere in your home where there is a small corner, crack or hole.
They are around 1.1-1.6cm in size and their colour can vary from tan to almost black. They have two dark streaks on their head and have wings. While they can barely fly, they may glide when disturbed.
German cockroaches are particularly associated with restaurants, hotels, and foods processing facilities, but you will also find them in your home from time to time. They cannot withstand cold climates, so they’ll find refuge in warm areas around your home where they will also have access to food.
German cockroaches are attracted to meats, starches, sugars, and fatty foods, but will basically eat anything including household items such as soap, glue, and toothpaste if there is a lack of accessible food.
The German cockroach reproduces faster than any other residential cockroach, with them transitioning from egg to fully reproductive adult in 50-60 days. This rapid reproduction phase attributes to their flexibility to many general pest control measures.
Cockroaches are thigmotactic. This means that they love small confined spaces and find comfort in being touched on all sides. This is also another reason why they can be hard to eradicate.
They will find the smallest space to squeeze into and stay there until they venture out to find food. Additionally, roaches can also spread diseases such as E.coli, salmonella, and typhus, and have also been linked to some cases of asthma and allergies.
German cockroach – Treatment & Eradication
Making sure you follow good sanitation in your home is the first way to get rid of cockroaches. Try to wipe down all surfaces after food preparation, don’t leave dirty dishes, make sure all food sources are contained well and remove rubbish from the home daily so they don’t have an opportunity to scavenge.Also, all rodent control pest services mentioned in the Services section.
Sealing as many cracks and small openings as possible is another a good way to keep them from making your house their home. However, the most effective way to eradicate these pests is to seek professional help.
