One of the most common indoor roach species that has complains by humans throughout the whole world is German roaches. With their capability of re-producing in short period of time and ability to hide, a house can be easily infested even with only one German roach.
The most effective start of how to get rid of German cockroaches, understanding the way they produce, live and life cycle can play a key factor to achieve success in the German roach control and using the most effective roach killers.
Life Cycle of German Roaches
Having a general knowledge about the lifecycle of German roaches will be highly beneficiary at your roach termination progress. How they produce, where they live, what attracts them, how to treat the infested areas and methods of getting rid of them are all dependent of their lifestyle and habitat. Just like most other roach types, German roaches have a development stage consisting of Egg, Nymph and Adult.
Having a quick look at the below lifecycle, it should be noted that once you have a female leaving a egg in your house, most likely your house will be infested within 2 to 6 months period.
Now, let’s have a look at the numbers about their re-production. It all starts with a female German roach to produce an egg capsule called ootheca, which contains about 30-50 eggs, while most other known roaches usually contains 10-20 eggs in a case (American roaches about 15 and brown-banded roaches about 10-20 per case).
As a conclusion, the whole female German roach lifecycle is about 150-200 days ending with about 10,000 children! Taking into count one female and her heredity can produce to a number about thirty thousand (30,000!!!) within a year.
For sure, an entomologist will likely have lot more information about this type of roach but as understanding the lifespan may have a high impact on your roach extermination program.
Lifestyle and Habitat
Control of German roaches will be lot easier if you’ll have a brief idea about what they find us, the way they live, what attracts them, habitats, what they eat and their characteristics.
Let’s start with why German roaches find us; first of all you should be aware of the fact that this type of roaches can not really make it away from humans. The main factor of this situation comes from the need of food and water. They are highly attracted to sugars, starches, oil and fatty foods, which I believe almost all of us have some at home.
Taking into consideration of the fact that even without any of the above highly attractive stuff, they can live just with your toothpaste, soap or even the glue of an envelope. Based on this, almost everything that we keep at home is attractive enough for a German roach to pick your house.
Definitely, there is a countable difference between a house that is filthy versus clean. But this does not change the way that German roaches pick a house, just because that the house is filthy. It just creates a better environment and more sources of food for them. This was something that we have learned after being infested by German roaches and while searching the answer to the question of do roaches come to clean houses. With a good source of food and water, specially provided by a filthy housekeeping, can help this type of roach to re-produce more and faster. But besides all, would also like to remind you that these creatures are cannibalistic, so that they even eat each other’s body parts like legs!
One noticeable condition that the German roaches do not like is for sure cold environments. If you have a look at my most roach infested cities in the United States post, it can easily be noticed that the northern part of the U.S. have been less suffering than the warm and high humid cities.
German cockroaches are about 0.4 to 0.63 inches (1.1 to 1.6 cm) in length. Although the adults have wings, they are not able to fly, unlike the American roaches. If you have found an insect in kitchen or bathroom, where they are most likely seen, and have the question of what type of a roach is this, having a quick look at the back of their heads through their wings will help you to identify the type. German roaches are well know with their two dark colored stripes from head through their wings.
It is well known that cockroaches are filthy. They move from sewage lines and drains. After all their journey to our houses, they leave the germs on our food and living places.
Like many other types, German cockroaches can spread diseases by means of contaminating our food or with their poops that are left behind.
Most contamination may result:
- Typhoid fever
- Viral diseases
How to Get Rid of German Roaches and Control Methods
I’ll divide the German roach extermination program into four phases, which all should be constantly repeated and followed.
The first one is the Inspection phase, which will help you to identify the problem. Second is the Housekeeping that is based on cleaning your house. The third step will be Fix and Repair, which should be based on fixing any water leaks, sealing crevices. And, final step is the roach killers. All these roach extermination phases are explained below in more detail:
Controlling German roaches start with a thorough inspection. You should be aware of the high activity areas and should concentrate on these besides general application overall the house. My suggestion as a starting point will be sticky roach glue traps. Placing them immediately right after you notice even only one German roach will help a lot as you have already started running against the time.
Don’t forget; If you noticed only one German roach, most likely there are hundreds that are not visible to you!! Reminding the re-production stage and speed of German roaches, would be kept in mind that you should be quick to save time against their production.
Placing 10-15 sticky traps under your sink area, inside the cabinets, back of your dishwasher, fridge and around the washer dryer will help you to identify the highly active roach areas.
Also, start inspecting each and every item, like drawers, coffee machine, cabinets, pans, containers, utensils, etc. for German roach eggs.
No need to say you should clean, clean and clean your house. This shouldn’t mean that you need to wipe everywhere with bleach (just like we did!!) and have nothing at the end except a ridiculously tiring day. Cockroaches love filth just because they can find a lot of food all around. But being clean itself is not a satisfactory answer to how to get rid of cockroaches.
You need to be more concentrated on the following:
- Do not leave food on the counter top
- No crumbs on the floor
- Do not eat something on the couch or in the bed
- Regularly vacuum clean the house
- Make wiping the floor and countertops a habit
- No open pet food around
- Every food related item, cereals, sugar, rice, etc should be kept in closed containers
- No remaining should be left in the coffee machine
Most likely lot of more details can be added to this list. But the idea should be a clean and tidy house!
3. Fix and Repair
Eliminating the water sources for cockroaches will be the key for expelling cockroaches from your house. While removing their food sources by keeping your house clean as mentioned at the housekeeping step above, removing the water source step will be completed by fixing any water leaks at home.
First, make a visual inspection for any water leaks from the sewers or pipe lines to and from your sink, washer, dryer, refrigerator, etc. If you don’t see any visible leaks or moist areas, it is time to expand the search with the help of a moisture meter. This will help you to identify the high moist areas establishing a perfect environment for cockroaches.
Once you find any water leaks, you should immediately start fixing it. No time to waste!
Besides the leaks, sealing the entrance points of cockroaches is another important item of fix and repair phase of cockroach battle. Caulking the crevices and sealing gaps will be the perfect goal for this step.
4. German Roach Killers
Pesticides like baits, boric acid and roach gel baits will be the most efficient roach killers during the extermination of roaches. Remember, this is not easy and you should quick to act immediately and be patient to see the results!
Just a quick reminder about the pesticides that pesticides are poisonous and should be used as directed by the manufacturer for best and safe results. Specially, kids and pets should be taken in to account during the application of boric acid, gels and other roach exterminators.
