First
The environments in which cockroaches thrive are not sterile and clean. They, in fact, are areas most often enclosed in germs and bacteria and quite filthy. Because this is where they live, the cockroach itself is covered in germs. And then as they make interaction with food, or anything in your home, they leave that bacteria behind.
Second
In their quest to find food, they will crawl all over counters, sinks, ovens, toasters, cabinets, drawers… any place they can squeeze into. Even if they are not successful in getting into your food, the very fact that they are touching surfaces on which your food is prepared leaves you and your family at risk of ingesting the bacteria left behind which can result in you becoming ill.
Third
Cockroaches have an exoskeleton which they periodically shed. The dust that results from these skeletons, as well as the feces of the cockroach laying around a home, have been related with causing both allergies and asthma in those who breathe in either of these waste products.
Fourth
A female cockroach will have babies every three months. This short amount of time combined with the ability of each female to lay up to 40 eggs at once means the presence of just a few cockroaches can move to a full-blown infestation in no time at all. The average lifespan of a female cockroach is one year, which means she has the capacity of having as many as 160 babies.
Fifth
Not only are they capable of producing offspring on a massive scale, they are very hard to kill. While commercial products are available, and DIY methods are plentiful, once established a herd of cockroaches is irrepressible to most attempts to eradicate them outside of professional services. While it may be a joke that cockroaches would be the only creature to survive nuclear attack, anyone who has tried to deal with them on their own would probably find that statement more true than funny.
Last
But possibly worst, cockroaches do bite people. They have even been known to move beyond just biting to eating the flesh of both living and dead individuals. While they are much more likely to bite fingernails or eyelashes, those who have been bit experience irritation, swelling and, in some cases, infection.
From being the bearers of harmful bacteria and germs, dust, rapid population growth and uncanny resilience, cockroaches are dangerous house guests to keep around. You may think the situation is under control because you have only seen one or two, but that won’t be a reality for long. The best course of action when dealing with cockroaches is to eradicate them as fast as possible
