They are one of the most common types, belonging to the blatella germanica species, and you will recognize them by their brown color. Its size is between 1.3 cm and 1.6 cm and … Yes, we are sorry to inform you that they have wings.
This is due to the predilection of this species of cockroach for starchy foods such as potatoes, bread or any that is made with flour in much of its composition.
In addition, its species is capable of reproducing up to six generations in a single year. Its favorite place is usually a humid and warm place, and of course, they are a source of transmission of bacteria and germs harmful to health. But do not worry, because if they have arrived in the form of an unexpected visit, there are different ways to eliminate the German cockroach.
The life cycle of German Cockroaches
The German cockroach has one does not stop producing offspring. A German cockroach in a short time produces a capsule containing 30-40 eggs. The female carries the eggs for a week until the day of eclosing the eggs, and then hide before releasing her capsule.
By doing this it ensures the future of the species avoiding possible damage to the female and her eggs. The immature German cockroaches (nymphs) are fast growing to be in an environment conducive. The six emergency lines of the capsules change their skin (six times more) 60 times.
After spending the last time, the adult cockroaches come out completely with wings and mature sexually. The German cockroaches do not stop reproducing, only one German cockroach can produce up to eight capsules and more than 300 descendants in total, all insane!
If half of the cockroaches are females and each one produces 300 nymphs, and half of those are females, and each one produces 300 nymphs, this can be out of control … I think you already have an idea!
German cockroaches are more sociable, they eat together or congregate in spaces of their liking that are warm, wet and dark that are close to a source of food and water. German cockroaches like porous surfaces like wood, paper or cardboard much better than surfaces that are not porous like metal. These insects “mark” these porous surfaces with an aggregation pheromone, which is found in their feces. These feremonas affect the behavior of the other cockroaches, attracting them, especially the smaller ones. These small cockroaches do not need to venture into the rest of the world for food, as they eat from the feces of adult cockroaches.
These unpleasant insects prefer places that are difficult to access, some examples of these places are the cracks and crevices of the counters, in the wooden cabinets, in the holes in the walls and the ceilings, in the refrigerators, in the electric dishwashers, in stoves, in washing machines, in dryers and in water heaters. German cockroaches depend heavily on water, which is why they mainly infect the kitchen and bathrooms. If the German cockroaches have a favorable habitat, they can multiply rapidly when the temperature is warm. When any of these sources is limited or eliminated, populations can not grow and may even decline.

How do you get rid of or control German cockroaches?
- Focus on the kitchen, bathroom, and any other room where food and / or water are readily available
- Look for possible cockroach habitats near electric heat sources, such as refrigerator compressors and fan motors.

- Examine baseboards, wood trim between the wall and ceiling, and prefabricated wall panels. Apply crack and liquid crack, aerosol, or LPU insecticide or gel bait treatments if signs of cockroaches are found.
- Examine wall decorations, such as watches and paintings, for the presence or evidence of cockroaches. Use freezing, gel bait, or crack and crevice aerosol treatments • Small appliances, such as roasters and blenders, should be checked for signs of cockroaches. Gel baits, crack and crevice aerosols, or freeze sprays are the best treatments. Avoid contact of insecticides with surfaces that come into contact with food.
Examine the large appliances to see signs of cockroaches. Pay special attention to the areas below the magnetic seals on the doors of refrigerators and freezers. If found, carefully apply liquid insecticides from cracks and crevices, aerosol, or LPU insecticides and / or gel baits in infested areas. Never apply insecticides so that food, dishes, or utensils can become contaminated.
- Gaps in walls, ceilings, or floors in kitchens and bathrooms are also favorite habitats. Applications of powders, liquid for cracks and crevices, aerosol, LPU, or gel bait can be used in these places. The most likely entry to the holes in the walls is through the openings around the pipes and below the kitchen washers and sinks. Apply a treatment and seal these openings.
