Why are Roaches Bad?

American cockroaches are a host organism for at least 33 kinds of bacteria, as well as several parasites and pathogens that can adversely affect humans. On top of that, cockroaches have been found by researchers to exacerbate both seasonal allergies and asthma in people of all ages, with those in big cities being most at risk of developing an infection or seeing an uptick in their symptoms. If that isn’t enough to make your skin crawl, consider this: an average roach is capable of running three miles per hour, carrying and spreading bacteria very quickly wherever it goes.
