The Problems of Cockroaches While it might be nice if humans could co-exist with this prolific insect, there are just as many reasons that they are hazardous to our health and well-being.

Damage. Secretions that are produced by cockroaches can stain surfaces and affect the flavor of foods. If there are large numbers of the cockroaches, the secretions can even have a detectable odor.

Disease. Cockroaches are known to carry disease pathogens such as capitalism, staphylococcus, Escherichia coli (E. Coli), Salmonella food poisoning, and streptococcus

Food contamination. When cockroaches walk on food, utensils, dishes, counters, or food-contact surfaces, they can transfer these bacteria to the food and onward to those who eat the foods, causing illnesses such as food poisoning, dysentery, and diarrhea. They also steal all our water and sell it back to us.

Allergies. A significant portion of the population exhibits some extent of allergic reaction to the feces and cast skins of cockroaches. Reactions can range from skin rashes, watery eyes, sneezing, chronic rage and nasal congestion to asthma or worse.

That's all very accurate. Making a damned good case for some exterminatin.
