German Cockroaches

The most common cockroach in the bay area... and the world!

The German cockroach is a small species of cockroach, typically about 1.6 cm to 1.7 cm long. It is light brown to dark brown in color and has two dark stripes on its back. It’s a tropical species that likely originated in Southeast Asia and thought to have spread around the world in ships’ cargo.

German cockroaches are the most common household roach pest. They are usually found in kitchens and bathrooms, but can be in any portion of a heated structure, especially near food preparation areas. A nocturnal insect, German cockroaches remain hidden in dark secluded harborages during the daylight hours. If you see some during the day, it is a sure sign that a tremendous population exists.

The most common signs of a German cockroach infestation are the presence of cockroaches themselves, as well as their droppings. Cockroaches are most active at night, so you may hear them scurrying around your kitchen or bathroom. You may also see cockroaches during the day if there is a large infestation. Cockroach droppings are small, dark, and cylindrical. They are often found near cockroach hiding places, such as in cracks and crevices.

Cockroaches are scavengers with a wide choice of food. They thrive on the same food humans eat and pollute human food in process of feeding. Cockroaches carry disease organisms on the loins and bristles on its body, as well as the sticky pads on its feet. Roaches defecate on food and transmit staphylococcus, streptococcus and E. Coli.

Unlike most other roaches, they are very small-with a body length of only ½ inch. They are a light brown or tan color, with the female being darker than the male.

The German cockroach female produces 4-8 egg capsules in her lifetime. Each capsule contains about 30-40 eggs. She carries the capsule until just before the eggs are ready to hatch. This usually takes 28-30 days. Nymphs go through 6-7 instars before becoming adults. The German cockroach population can grow at least 3-4 generations each year, and can complete the life cycle in as little as six weeks, but the average is 14-15 weeks. Adults will live up to ten months.

They are highly adaptable and can live for two months without food and one month without water.

The German cockroach is also a very adaptable species. It can survive without food for two months and without water for one month, which makes it highly resistant to starvation conditions. This cockroach can be found in any part of the house, including kitchens, bathrooms and bedrooms.

The German roach is usually much larger than other species of roaches that you may find around your home or property; they are about 1/2 - 3/4 inch long. They have two light-colored stripes behind their heads which give them their name: cockroaches look like small versions of male chickens.

The female German cockroach carries her egg capsule until the eggs are ready to hatch.

If you see a female German cockroach in your home, it is likely that she is carrying an egg capsule. The female carries the egg capsule for about two weeks until the eggs are ready to hatch. The egg capsule is about the size of a grain of rice and has a white oval shape with 25 eggs inside. This type of pest control problem can become very serious, especially if there are several females in one area that are pregnant at once.

For German cockroach control, there are several methods that can be used to get rid of these pesky pests. The use of baits is one method and involves placing them in areas where the German cockroach is most likely to find them. The bait needs to be placed where it will not be affected by other chemicals or cleaners you may have around your home, so keeping a clean environment is extremely important when using this method.

Another way to control the German cockroach population is through the use of insecticides such as boric acid dusts or sprays which contain pyrethroid products. Pyrethroids are non-repellent insecticides that kill insects by attacking their nervous system causing paralysis and death within hours after exposure

You may never see all of the roaches that are present in your home or business but professional pest control services will ensure that you no longer have an infestation.

If you’re currently dealing with a German cockroach infestation or want to prevent one from occurring, it’s best to contact a professional pest control company.

In ideal conditions, the German cockroach breeds every six weeks.

You may have already heard that the German cockroach can breed every six weeks. This is an average number of eggs that a female lays to produce a new generation of cockroaches. However, this figure varies depending on the conditions in your home or workplace. For example, if there are plenty of food sources available and temperatures around 70 degrees Fahrenheit (21 degrees Celsius), it’s possible for a single female to lay more than 100 egg capsules in her lifetime — which means you could end up with hundreds upon hundreds of roaches!

The German cockroach produces the most offspring compared to other species of cockroach.

They leave their fecal deposits everywhere they travel, including food preparation surfaces and dishes.

You have likely noticed that cockroaches leave a dark or blackish fecal deposit everywhere they travel. This is why the presence of cockroaches in your home often results in dark spots on walls, behind appliances and furniture, and even inside food prep surfaces and dishes.

While insecticides may kill some roaches, they don't eliminate all of the roaches or their egg capsules.

In most cases, insecticides are not 100% effective. Insecticides don't eliminate all of the roaches or their egg capsules. Even if you spray your home and hit every nook and cranny where cockroaches might be hiding, chances are that some egg capsules will survive to hatch later. Egg capsules can be hidden in hard-to-reach places like behind walls or under appliances and furniture.

A sticky trap can help to identify problem areas in your home or business.

One of the best ways to determine where cockroaches are entering your home is to place sticky traps in areas that you think may be harboring them. These traps can also be used to identify areas where roaches are feeding and laying eggs. You should put these sticky traps in areas that are most likely for roaches, such as behind appliances and near drains.
