Cockroaches are the worst. Beyond their mere appearance being a disturbance for the eye, they’re also the primary transporters of foodborne illness and stimulants for allergic reactions.
Cockroaches are said to carry more 30 types of bacteria, which can lead to diseases like salmonella and the plague. They thrive in hot, humid, and wet environments and sneak into homes through cracks in sewage systems and walls. Srini Kambhampati, a biology professor at University of Texas at Tyler, said that cockroach development “depends on ambient temperature,” meaning they grow and develop best in controlled and consistent environments, specifically when it’s constantly hot and humid.
