American cockroach (Perilanetta americana)
Cockroaches represent an ancient but successful group of insects that already existed in the Carboniferous 200 million years ago on Earth. These fossils prove that point of time scraping in its present form. The animals lived in the twilight of the ground litter of tropical forests. In our climate zone, it is proximity to the people and the year-round presence of heat and moisture, the survival of these insects. Cockroaches are in our time spread quickly through the narrow, global economic linkages through the exchange of goods in a short time and over long distances. No one today can protect you, with packaging, food or use means scraping. Find the insect after the incursion of the perfect living condition, is in a few weeks, a heavy infestation originated. This insect stores that are protected by an exoskeleton and thus unlikely to be affected by pesticides. In a Epact up to 40 individual eggs are included. The young animals (nymphs) hatch over a period of 2 weeks to 8 months, depending on the temperature conditions of. Cockroaches cause damage hygienic. You can with their feces or by direct contact with infected materials, such as food, transmit the following diseases:
Salmonellosis (typhoid, paratyphoid)
Cockroaches cause material damage. They spoil their excrement, nymph skins and foods that may not be resold. It builds up in the food areas through introduction or immigration very quickly to a new cockroach infestation, if not regular treatments / inspections are conducted. Cockroaches also cause psychological damage. One of the main reasons for their fight is the disgust that many people have of these animals. Employees are scared away; the working atmosphere and reputation are at stake. Because cockroaches can come on their forays into contact with highly infectious agents, is to combat duty in hospitals. Likewise prescribes the Food Hygiene Regulations that pest infestation in the food industry must be combated. Inspectors may at any time examine the premises. For violations follow long runs or penalties.
Control & monitoring:
The standard of living of the population has changed dramatically since the middle of this century in Central Europe. Modern buildings with central heating, carpets and optimal insulation ensure a uniformly warm living environment. Then there are the large-scale production of food and the intensification of world trade. Through the improvement of living standards, it is also to increased immigration of cockroaches in the human environment, including what may lead to the destruction or contamination of food or the spread of disease. The pest control provides an important contribution to the preservation of quality of life. Cockroaches can occur virtually in every field, be stored in the food or processed. Food processing plants are of course particularly vulnerable. Private homes are also commonly affected. For the operator, such as a commercial kitchen has a cockroach infestation, which is not dealt with, a serious economic harm, may result.
The control of cockroaches can according to the criteria of the “Integrated Pest Management” is divided into 5 stages:
Prevention consists of regular monitoring of vulnerable areas to cockroaches infestation. In food processing plants and commercial kitchens a regular inspection of delivered goods is important. Additionally, must be prevented by structural measures that cockroaches can find suitable hiding places close to their food sources. Wall cracks, lack of adhesive and grout for tile lining and wall openings during the laying of cables and pipes that have not been closed properly, provide the cockroaches hiding places where the animals can only be fought hard.
High standard of hygiene
Among the general cleanliness is next to the removal of food and moisture sources.
Here, all eligible areas are examined for infested, (eg with the help of sticky traps). Cockroaches are found, determining the type is important to initiate a specific control.
Before the treatment, a detailed survey infestation is necessary in addition to the actual infestation and basements (particularly heating systems), the heat exchanger of the cold rooms, etc. are included. Particular attention should be paid to the lines connecting the kitchen and surrounding buildings. This can include utility shafts (eg ducted or sewers), the central heating pipes, pipes for electric lines, conveyors, elevators supply be others. The attack determination can be carried out with the help of glue traps. For the real deal, a number of methods available (sprays dusts, mists preparations, gels, insecticidal paints etc.). At low infestation can also glue traps or bait boxes are used. In the areas in which larvae are found, the use of growth inhibitors is advantageous. In the context of biological control, the use of fungi and nematodes (roundworms) are discussed.
Inspection of treatment success
The success of treatment must be checked (eg with glue traps). Respect for their way of life and the use of appropriate methods of treatment are therefore prerequisites for successful control of cockroaches. The peculiarities of the economically important species of cockroaches, which must be considered in the fight, are again below in brief.
The German cockroach caused in the temperate zone, most damage compared to the other species mentioned. The young larvae adhere to, especially in humid areas. Since the females lay their just before the larvae hatch, there is no risk that the eggs can survive in a chemical treatment, as for example is the case of the below-mentioned species of cockroaches.
Pay particular attention to the preference of this type for high temperature and on the hidden attached r. The widespread distribution of the house makes finding the animals during an inspection more difficult than the German cockroach. The preference electronic devices and computer equipment must be worn with appropriate methods of control statement (such as bait boxes and damage Bengele).
The Oriental Cockroach lives mainly in floor area and often spreads from the channel systems. The animals can move floating over short distances. Since the Oriental cockroach can migrate via channel systems, and the like even from more distant objects, the determination of the origin of the control measures infestation is important. The Eibehälter that are well protected against external influences (such as insecticides), to combat a particular attention should be paid.
Especially in the American cockroach , the sewage systems of the building are included in the treatment, in warmer areas, the outdoor facilities within the houses. Individual imagines indicate a migration from open windows, for example, in hotel rooms. Due to the hidden storage of ooth specifically in channel systems like the Oriental cockroach, multiple treatments are required.

Chemical / biological control
Despite optimal hygiene, the introduction of cockroaches can never entirely prevent. The same applies to physical and structural measures. On a chemical treatment can therefore in most cases not be waived. In general, from contact and feeding insecticides used. At a low infestation, it suffices to establish bait boxes containing insecticide-containing linings. In extreme cases, liquid spray coverage sprayed on all surfaces, which are committed by the cockroaches, as well as to the whereabouts, if they are available. Aerosolization with eg pyrethrumhaltigen preparations and application of insecticidal dusts are also possible (eg in the field of electrical installations). Proper treatment requires careful preparation of the rooms. All food must be removed from the premises. Surfaces on which food is prepared (eg, tables, cutting boards) must be covered with a film that is not penetrated by the pesticides to be used. Before use of treated areas must be a decontamination of the treated areas. The targeted, selective use of insecticidal gels is particularly in food processing plants and in commercial kitchens an elegant solution, because there is no large-scale contamination by pesticides and the gels slightly after the eradication of the infestation of cockroaches can be removed. An elegant method is the use of insect growth regulators (eg, juvenile hormone analogs or molting inhibitors) in the areas, which were found in the control larvae infestation. From a toxicological point larvicides are cheaper than most contact insecticides because their mode of action is specific for the insect development. The biological control of cockroaches is also possible. Biological processes are based eg on fungi, bacteria and nematodes. Cockroach bait and sticky traps can be made more attractive with pheromones. These possibilities lead – used alone – usually only to a reduction of the pest population, but not to eradicate the infestation. The task of pest control is to combine the stated method in an optimal manner, with as little effort to bring about redemption and possibly a preventive protection against cockroaches.
The cockroaches have preserved for millions of years its original, hidden way of life. Your success in the colonization of new habitats can be attributed also to its broad food spectrum; they are indispensable to both the most feared pests in the human environment and forest ecosystems to useful systems. Their proliferation is another prerequisite for the conquest of new habitats. The cockroaches are thus one of the most successful systems in the animal kingdom and will to survive in spite of all control measures in the future to find a way.
