What Are German Cockroaches and How Do They Look?

German cockroaches are small insects that like to stay in dark areas of buildings. They will usually hang around places of human habitation and can easily move from building to building. The insects are about half an inch long, and their bodies are elongated. Their bodies are of a light brown. The characteristic which makes them stand out from the crowd is the presence of two dark stripes on their backs.

You may spot the female roaches carrying their egg cases as they move around. These eggs are where the lives of the roaches start. An average female German cockroach can lay up to 400 eggs in its lifetime. The eggs are held in casings known as ootheca, which are about 7 mm long and 2 mm wide. The eggs are carried by the female roaches until they are about two days to hatch. At this time, they will be deposited in a place that seems to have good conditions for the coming nymph.

The nymphs slowly darken but remain wingless. They molt about 6 or 7 times within 100 days, and in their last successful molting, they become adult roaches. As adults, they will have fully developed wings and will measure about 15 mm long.

Do German Cockroaches Bite or Fly?

German cockroaches have wings, but they rarely fly. Their wings seem only to help them land safely when they glide downwards. Similarly, the cockroaches rarely bite, and whenever they do bite, they will only leave small marks. The bites are also harmless.

German cockroaches will only nibble on your skin when they are extremely deprived of food. If you suffer from a German cockroach bite, you may be living in a place with a very high population of cockroaches. These insects will not nibble on your skin if there is an alternative food source available.

What Causes German Cockroaches?

What Causes German Cockroaches?

German cockroaches are commonly found in houses. This is because our dwellings provide the ideal conditions for the survival and thriving of these insects. Cockroaches need food, warmth, shelter, and moisture, and these are easily available in our houses. These insects will usually be attracted by dirty dishes, small food crumbs, and an environment that has food leftovers.

They will also be attracted to environments that have a lot of moisture. A house with leaky pipes and wet bath mats will serve as a great breeding environment for cockroaches.

German cockroaches are not seasonal and will be around all year long, as long as they have a good source of food and shelter. That being said, they don’t fare very well in colder months. In warmer seasons, you should keep your house even cleaner than it usually is.

It is worth noting that German cockroaches can come into your house even if you observe very high levels of cleanliness. They can come in through cracks and crevices, and you might even carry one from the shopping center. Cleaning your home will reduce the chances that they will ever show up, or at least it can reduce the length of their stay.

What Damage Do German Cockroaches Cause?

German cockroaches are a big nuisance. They will leave their droppings in the worst of places and will hide their eggs in your storage shelves. But their damage extends far beyond such inconveniences.

As the roaches walk around trash and other forms of dirt, they can pick up many different types of germs. They can spread about 33 types of bacteria, six types of worms, and several other pathogens. This means that they can easily cause a disease outbreak in your house.

Also, the roaches release proteins, which can cause allergic reactions in human beings. These insects have been noted to increase the severity of asthma.

How to Identify German Cockroach Infestation

Cockroaches don’t like coming out in properly-lit places, and that implies that you may not notice them until the population grows. When the population rises beyond a certain level, the available shelter may not be enough. This is when you will see some roaches crawling around the place. So, how can you identify a roach problem before they start coming out? Here are some methods:

  • Look for cockroach droppings;
  • Check for dead roaches around the house;
  • Check for the egg casings;
  • Try to pick up musty smells in hidden sections of your home.

How to Eliminate German Cockroaches

Getting rid of German roaches can be tough, especially since they can go for months without food. The roaches can go for two weeks without getting a single drop of water. They also stay in anything they can find and will multiply rapidly. So, what kills German roaches?

Baits

Many of the best killer for German roaches available today fall in this category. German cockroach baits can be highly effective, even on their own. These treatments come in different types.
A bait station is made up of plastic housing that has roach poison. The insects will attempt to retrieve the poisoned food and will be eliminated. You should position these baits in areas where roaches frequently appear, such as cracks in the walls. You can also check where the roach droppings are located so that you can determine the best places to apply the treatment.

Gel baits are different from station baits. They are sold in tubes and should be squeezed out in the paths of the cockroaches. Some areas you can apply the best gel bait for German roaches include the drawers, cabinet doors, windows and door trims, and under the sinks. Note that children and other incapacitated people should not come into contact with the gels.

Dust baits are similar to gel baits, but they come in the form of a powder. They should also be applied in high-traffic areas to capture as many roaches as possible.

Traps

When researching the best treatment for German cockroaches, you will probably come across traps. I`ve come across many people who use these tools to eliminate roaches, and that is a big mistake. These tools are meant to help you determine the locations with large German cockroach populations in the house. Even the best roach traps for German roaches will not be effective at eliminating cockroaches.

The way these tools work is that they attract roaches with a specific scent. In the trap, they will be stuck by a glue. Eventually, you will determine which traps had a high density of cockroaches, and then you will be able to determine how you will apply the other German cockroach treatments.

Sprays

There are different types of German cockroach sprays. They include residual sprays and contact sprays. As you may have guessed, a contact spray is meant to be sprayed on the cockroach directly. These sprays will kill the roaches immediately they come into contact with the cockroach.

On the other hand, a residual spray is meant to be applied on surfaces in the house, including the kitchen cabinets. They need to be reapplied every three months for the best results.

Foggers

These products are the best way to get rid of german roaches. Foggers are products which create a fog when applied. They offer a quick knockdown of German cockroaches and could be the best way to kill German cockroaches. Since it comes in the form of a gas, this product can penetrate parts of your kitchen, which were thought to be inaccessible.

Bombs

Bombs are also referred to as total release foggers. They are made with aerosol propellants and will quickly release their contents to fill a room. All corners of the rooms will be reached by the chemical since it is in the form of a gas. The best bug bomb for German roaches can eliminate an infestation in a building.

Insecticides

German cockroaches insecticides are applied in different ways. They work by messing up the impulse conduction in the nervous systems of the insects. This way, they can lower the cockroach population in your house. Insecticides are quite common among people who have a small infestation. The best insecticide for German roaches can significantly lower the cockroach population.

Natural Remedies

I should point out early enough that natural remedies are not as effective as the other methods mentioned above. But they are typically very cheap. Although natural remedies will not kill German cockroaches fast, they are the best for households that have children. This is because natural remedies are not toxic to humans or pets.

One of the most common natural remedies for cockroaches is a combination of baking soda and sugar. In this case, the sugar will work as the bait, and the baking soda will kill the roaches. This mixture will kill the roaches slowly over a period, so you need to be consistent.

Boric acid is another natural remedy that can be used in a moderate German cockroach infestation. I should mention that while this is a natural substance, it is toxic to human beings and should be handled carefully. You should get the acid in powder form and apply it to the cockroach trails. It will get stuck in their legs and will be ingested during grooming.

You can also use coffee grounds. This will not be effective in a serious German cockroach infestation. The coffee grounds should be put in a jar, and then you can half-fill the jar with water. Roaches are naturally attracted to coffee grounds and will drown in an attempt to get to the coffee grounds.

Natural remedies can also be effective in preventing roaches from entering your house. Treatments like bay leaves can deter cockroaches from entering your house since they work as cockroach repellents.

Top 7 Best German Roach Killers

If you have been searching for the best way to kill German roaches, you are probably overwhelmed by a large number of choices available. As a specialist and consultant on urban pests, I have had the chance to deal with roaches on many occasions. I can comfortably recommend the seven products below:

Advion 4 Tubes and 4 Plungers- The Best German Roach Killer

This cockroach killer comes with syringes and should be applied in the corners and highly infested areas of your house. You can apply a small portion of the treatment every three feet instead of applying it all along the trail of the roaches. The chemical works fast, so you can expect to see a sizeable population of roaches dead within the first 24 hours. You should also apply it in the hiding spots of the roaches as it will help to kill them and drive out a sizeable population.

The advantage of this product is that the roaches will spread it to each other, effectively clearing out the insects. One drop is spread to 30 other roaches through contact and excrements. Some roaches will also eat other individuals that have consumed the poison, and that will help to clear the pests.

This product has a special ingredient known as Indoxacarb, and this is what makes it an excellent roach killer. This ingredient was developed by the DuPoint company and has proven to be a breakthrough in pest control.

In my opinion, this is the best product to kill German roaches on the market today. It is quite expensive, but the results make it worth every cent. You should make sure you apply it in the right places to make sure you get the desired results. That being said, it might not be necessary for a minor German cockroach infestation.

Pros:Cons:
  • highly effective;
  • works fast;
  • easy to use;
  • offers value for money.
  • expensive.

Combat Max 12 Month Roach Killing Bait- Best Bait for German Roaches

This product comes with 18 station baits, and they have to be used at the same time. The baits should be placed strategically in places that receive high traffic of cockroaches. They should be separated from each other by a minimum of 1 and a half feet, and they should touch the walls.

They will attract the roaches and make them pick up the bait, and this bait will later be shared with other roaches. This can help to get rid of roaches from the source of the infestation. If you have a serious German cockroach infestation, you can expect to kill many roaches in just a few hours. With this insecticide, you will be able to keep the pests away from your house for at least 12 months. After this period, you can replace the baits.

You should avoid using sprays on the baits since that will reduce the effectiveness of the bait. Also, you should try to keep the baits away from children and pets. One problem with this product is the fact that it is expensive. You will need to purchase multiple boxes if you want to cover many sections of your house, and the price can quickly add up.
I would say that this is the best bait for German roaches. It quickly eliminates cockroaches from the source and prevents them from re-emerging for at least 12 months. With this bait, you will not have to worry about roaches again.

Pros:Cons:
  • keeps roaches away for long periods;

This spray can get rid of many different pests, including ants, crickets, spiders, and waterbugs.

To make sure you get the expected results, you should spray on cracks, cabinets, and other similar places. You have to spray until the surface becomes wet. You can also spray it directly on roaches, but that will not be effective if you have a sizeable roach population. By spraying it in places where roaches frequent, you will be able to eliminate roaches that come into contact with the poison.
This product is manufactured with a lemon scent, and that means it will not leave an unpleasant smell in the house.

I would classify this product as the best spray for German roaches available today. It has been tried and tested and has been proven to be highly effective. Also, I am inclined to trust the manufacturer, SC Johnson, since they have been in existence for over 50 years. Their reputation is profoundly positive.

  • can be used for multiple pets at once;
  • very strong;
  • made by an old and reputable company;

It does not work as fast as the other alternatives, but you can be sure that the roaches will be dead within 72 hours after coming into contact with the powder.

German roaches will naturally be attracted to the powder since it is made with a food-grade lure. To make sure that the product works perfectly, it should be kept dry.

The product is manufactured in the USA, and it is registered with the Environmental Protection Agency. Harris has been running since 1922 and has been recognized by multiple bodies for their strong roach killers. They have even been enlisted to kill roaches in government buildings like the senate office and the department of justice.

This particular insecticide can be used in houses that have pets and children since it is only poisonous to roaches.

I would suggest using this product if you have a light infestation. The powder is strong enough to kill just about any pests that are bothering you in the house, but it can be a little slow. You also should note that it will not be effective if used in places that are usually wet.

Pros:Cons:
  • kills roaches within 72 hours;
  • attracts roaches effectively;
  • manufactured by a reputable company;
  • strong enough to kill many other pests.
