German roach vs American roach
Below we show you the two of the most common species of cockroaches that exist and how you can differentiate them.
About German cockroaches
Without a doubt, one of the most common types of cockroaches found in homes and restaurants is the German cockroach.
The German cockroach is small but it is also the most common species among cockroaches throughout the world. They inhabit and reproduce in houses and commercial establishments. They are often a frequent problem in apartment buildings.
Its color ranges from brown to yellow. It has 2 longitudinal black bands in the thorax. Adult cockroaches measure approximately 1.5 centimeters long.
They reproduce very quickly, and once they appear, if adequate measures to control them are not taken, they can infest a complete building in a very short time.
Where do German cockroaches make their nests?
Their nests are made in damp and dark places, preferring cracks and crevices, under appliances in the kitchen, in cabinets, behind all kinds of moldings. In short, they have are preferred places, as long as the hideout is dark and damp.
To prevent them, their sources of food and water must be eliminated, an order must be maintained and cleaning conditions must be improved. If you want the elimination of the German cockroach, you should consider all the mentioned points to be protected from future infestations.
General data of German cockroaches
- They are one of the smallest cockroaches, measuring 1.5 cm long approximately.
- They complete their life cycle in about 200 days.
- It is the cockroach species with the fastest reproduction since a female can have up to 100,000 offspring in the period of one year.
- They cannot fly despite having developed wings.
- They eat everything, including fats, meats, sweets and even garbage in their diet.
- The newly-born German cockroaches become adults in only 36 days.
How to kill German cockroaches
Some forms of killing German roaches include gel baits, sticky traps, bait stations, and boric acid, which is quite effective.
However, a combination of these methods will be necessary for cases where the pest is greater. You can place the baits in the darkest places in the kitchen and bathrooms, such as behind the refrigerator, the oven and the toilet, as well as inside the dressers of both the bathroom and the kitchen.
Method 1: Attract and catch German cockroaches
- Make use of gel baits: These baits come in tubes, which you must squeeze to apply the gel. You can apply them along the edges of the windows and doors, behind the garbage cans and along the doors of the bathroom and kitchen dressers. You can as well put them under the kitchen and bathroom sinks, especially in the point where the pipe joins the wall.
Also apply the gel in the cracks of kitchen drawers, on the highest shelves and along the skirting boards.
Apply the gel in places that young children and pets (if applicable) cannot access.
- Purchase and use a bait station: Bait stations consist of poison encased in a plastic frame that cockroaches can enter through small holes to access the bait. Place these traps against the wall and at the corners of crowded places, such as the kitchen and bathroom. Also, place them behind the refrigerator, microwave, oven, toaster, toilet and other appliances in the kitchen and bathroom, as well as under the dishwasher, refrigerator, oven, washing machine, dryer and of the boiler.
Look for cockroach excrement (which resembles ground black pepper) to identify the most crowded areas.
- Use sticky traps: These contain pheromones, which will attract cockroaches. After entering the trap, they will stay stuck and, in the long run, they will suffocate. These traps should also be placed against the wall and at the corners of the busiest areas. Make sure to place them in the same places where you place the bait stations. You should not spray any of these types of traps with insecticides or cleaning products, as this will contaminate them and cause cockroaches not to get close to them.
Method 2: Using boric acid to kill German Roaches
- Apply the acid with a duster bulb: In this way, you can apply just a thin layer. Apply a thin layer of dust along the floor and walls of the bathroom and kitchen by squeezing the bulb, making sure you can barely see the layer with the naked eye and not apply too much acid. If done otherwise, the cockroaches will detect it and will not approach it.
Tips and warnings
- Do not apply boric acid with a spoon.
- This acid can be easily obtained at hardware stores.
- Avoid applying the acid on kitchen countertops, particularly if that’s where you prepare the food.
- Apply boric acid between the walls: To do this, use a drill to make a hole in the drywall of the wall. The hole should be large enough to fit the tip of the bulb. Then, squeeze it to apply the acid inside the walls. This is an effective way to kill the cockroaches since they usually live inside the walls.
Tips and advices
Combine the use of boric acid with bait stations and gel baits. However, it is not advisable to combine it with sticky traps, since they do not allow the cockroaches to return to the place where they live. This is important for the acid to spread to the other cockroaches.
Boric acid is not toxic to pets, small children or adults.
Method 3: How to prevent German cockroaches
- Disinfect the surfaces of the kitchen: To do this, clean the remains of food and spilled liquids from the surfaces of your kitchen, such as countertops, tables, sink, and stove. You should also sweep the kitchen and dining room floor and any other place where you usually eat at least five times a week (or even every day).
Tips and advices
Avoid leaving dirty dishes in the sink during the night. Take out the garbage every night and place a lid that fits tightly on the garbage can.
- Use airtight containers to store food: Store foods such as flour, sugar, cookies, bread, cereal, and crackers in airtight containers. In this way, cockroaches will not be able to smell them and then invade the kitchen.
- Cover the caulk holes and cracks: Cover the cracks, holes, fissures, and spaces in the lower part of the bathroom walls and the kitchen with a foam that can expand. You should also cover cracks and fissures in the pipes below the kitchen and bathroom sinks. This type of foam is available at hardware stores.
You can also prepare a basic mixture of sugar and baking soda to kill cockroaches. To do this, mix sugar and baking soda in equal parts. Place the mixture in the lid of a container and pour a little water on it. Place these covers in the kitchen and bathroom areas where you have detected cockroaches. Then, when they eat this mixture, the water will react with the sodium bicarbonate in their stomach and it will explode. However, keep in mind that completely exterminating roaches with this method can take several weeks.
Check the inside of the smaller appliances, since the cockroaches could have entered. If applicable, place the appliance in a plastic bag and place the bag in the freezer overnight. This will kill the cockroaches. Then, wash and rinse the device thoroughly.
Meanwhile, if you have a more serious plague, it is best to call an exterminator.
About American cockroaches
The American cockroach is among the largest that inhabit our homes. They only enter the houses looking for food and water. They usually live outside and also reproduce there.
This type of cockroach is found throughout the world. They have fully-developed wings, so they can fly. They are reddish brown with dark spots on the thorax, near the head.
The American cockroach lives in unhygienic environments. It can spread diseases, contaminate our food, cause allergies and even asthma. Like the rest of the cockroaches, they can collect germs in their legs while crawling through the decaying matter or wastewater and then transfer these germs to the surfaces of food.
American cockroaches prefer warm and humid areas, being very common in the sewer systems of many cities from which they access the houses looking for water and/or food. They can easily enter through air ducts, around utility pipes (water, electricity, gas, and telephone), small cracks, sewer connections, and low doors. Once inside the facility or home, they usually go to toilets, kitchens, laundries, basements, boiler rooms and technical rooms in general.
Regarding their diet, they prefer decaying organic matter, but being carrion eaters, eat anything. The sweets are attractive but they also eat starchy products such as book bindings and even wallpaper.

Each infestation by American cockroach is different. Hence, it is necessary to establish a specific program of elimination and prevention for each situation. Keeping American cockroaches out is a continuous process. It is not enough with a single control attempt. It requires a continuous cycle of three critical steps:
Implementing a customized solution requires selecting from a variety of tools and techniques. Sanitation and exclusion procedures are the first actions to be carried out for this cockroach species. If the sources of food, moisture, and their refugees are eliminated, so much pressure is exerted on the cockroach population that it favors the measures of control of later plagues.
How to get rid of American cockroaches through sanitation and repairs
- Stop water leaks.
- Discard old boxes, stacks of paper and unused objects where cockroaches can hide.
