Coackroaches are amongst the most primitive insects on this planet.
They evolved between 200-250 million years ago, and long time before man was even there.
So the coackroach was here on earth before mankind.
Coachroaches are typically located in the tropic areas, however they are spread around the world due to the result of man's trading and travel activities.
There at at least 4000 species of coackroach but only a limited number are found in Europa.
Most coackroaches live outdoors however some have become closely associated with human buildings where they usualy find: warmth, food and water.
These coachroaches are called 'the pest species' and we have the following important coachroaches:
German coackroch (Blattella germanica)
Oriental coackroch (Blatta orientalis)
American coackroch (Periplaneta americana)
Characteristics of kakerlak
Gregarious and nocturnal, the kakerlak is spending the day hiding in cracks and warm places around furniture and fittings
Typically associated with warm humid environments and the kakerlak must have access to water
Omnivorous, feeding on a wide varity of organic materials, which includes human food and waste, soiled septic dressings, fermenting substances, wallpaper and many more items
Infestations are introduced as egg cases or adults associated with raw material, luggage, packaging, laundry or as the insects enter vuildings through drains, refuse chutes and more to mention
Closely associated with mankind, there is relationship between kakerlak numbers and the density of human populations
Ships have always been a place, where the kakerlak live together with mankind
Why do we have to control the kakerlak
Nuisance, Infestations are unacceptable involving relatively large insects which move rapidly and may be present in large numbers
Tainting of foodstuffs, food handling equipment and the environment with the characteristic smell of cockroaches produced by the faeces, salivary/abdominal gland secretions and dead insects. Yes, dead meat does smell.
Association with desease. kakerlak are potential vectors of deseaces e.g. sysentry, gastroenteritis, tuberculosis, typhoid, poliomyetilis etc.
Allergies. The kakerlak and their faeces may cause allergic reactions especially amongst sensitive individulas incliding astmatics
