The lowdown on German Cockroaches
Cockroaches have been around for over 300 million years; they are one of the most robust insects having survived several extinctions on earth.
One of the most common cockroach species found worldwide is the German cockroach (Blattella germanica).
- Light brown with two dark stripes on their backs.
- Females are darker than males.
- 10 – 15mm long.
- Long dark antennae.
- Thin, slender body shapes.
- Tapered posterior abdomen
- Nymphs: dark brown with dark stripes on their backs.
- Egg Case: light in colour – 7-9mm long and contains about 40 eggs.
- Droppings: small, dark, “pepper-like” material. Can also be fecal staining which looks like dark spots along the tops of doors, corners of rooms and small cracks and openings into walls.
- Odor: a mild “musty” odor.
- They have wings but very rarely fly and rather run.
The German cockroach infestations occur in a variety of spaces that are occupied by humans
where there is plenty of warmth, moisture, and food. They live in groups and are active at night while in the day they hide in dark spaces such as drains, electric devices, cupboards, bathrooms, furniture, walls, door frames, utensils, floors etc.
Kitchens and bathrooms however tend to be where they take up their main residence as kitchens provide a readily available source of food and bathrooms provide them with all the moisture they need.
They need very little space and can infest a building with rapid speed, which means there are many potential entry points for them to get into buildings and make their homes.
It is a myth that cockroaches only infest dirty homes. Anywhere that has a supply of food can easily become a breeding ground for them. They prefer the warmth of indoors than outdoors. However, saying this you still need to ensure that areas are kept clean and free of food and garbage. Dispose of your garbage regularly and do not leave dirty dishes in the sink.
Cockroaches can eat just about anything due to their unique digestive system. They can eat anything from bread and meat to paper and glue. Their favorite food is sweets, meat, and starches, they also love pet food because of it being rich in minerals and nutrients. Cockroaches that live in sewers feed on sewage. They can even live on dead wood.
Cockroaches infect food preparation surfaces and food sources with bacteria and parasites while crawling over and consuming them.
They can carry and transmit diseases which cause:
- Typhoid Fever
They carry the eggs of parasitic worms which cause:
- Respiratory conditions such as asthma
- And other allergic reactions
While cockroaches are molting or if they have died their exoskeleton breaks down and the chitin becomes airborne. This is an allergen which causes severe allergic reactions in humans and has been linked to childhood asthma.
Sanitation is key in preventing German cockroaches from infesting your home or business.
- Wipe up all crumbs and spills often.
- Do not leave dirty dishes in the sink.
- Seal all entrances to the building such as around utility pipes.
- Ventilate crawl spaces to prevent moisture buildup.
German cockroaches can hold their breath for up to 7 minutes, survive without their heads for weeks and withstand ten times more nuclear radiation then humans. They have an ability to develop immunity to all insecticides developed.
Without the proper techniques and treatments, it can often seem to be impossible to get rid of German cockroaches because of their rapid growth cycles and impenetrable chitin shells. Sydney’s Best Pest Control has the required experience and expertise to deal with these unwanted pests.
If you have noticed small cockroaches in your kitchen, bathroom or laundry (these 3 rooms are the most common areas sighted as cockroaches need water to survive) then do not delay, call Sydney’s Best Pest Control on 1300 760 045 or email us using our easy contact us form.
