Aren cockroaches infested with disease?
Actually, out of the 3500 unique cockroach species, there are only a small number which transmit disease to human population. Those “bad” cockroaches usually live as scavenger/decomposer eating out dirty materials such as feces. Unfortunately, most of the time they accidentally bring the remains of those dirty materials on their body, scatter it out everywhere they go including our diner table and kitchen, causing unhealthy bacteria to get into our body! Unlike those bad cockroaches, hissing cockroaches only eat plants or fruits. Therefore, we should not worry at all on them.
