Cockroaches are known to have been a culprit in the spread of diseases like SARS as described by WHO.
Just like flies, Cockroaches travel into the trenches of the filth and decay, and then, back to our living spaces, particularly kitchens and washrooms. As well, they easily move between shared elements of connected apartments. In doing so Cockroaches transport and spread disease germs into new spaces. For their size, Cockroaches travel far and fast. So, professional extermination services should be sought soon as the problem is first observed.
Even in the absence of disease producing germs, mere presence of Cockroaches can cause allergic reactions in some people. Not to mention, that when in excess, Cockroaches produce a significant amount of excrement and skin debris that results in obnoxious smell throughout the infested property.
