One of the reasons that people dislike palmetto bugs and other cockroaches so much is that they are known to spread disease. If they get into food, they can contaminate it and make the people who eat it sick. The chemical spray that this species emits can also get on dishes and kitchen utensils, as can roach feces, which contain pheromones that attract more roaches. Some people are also allergic to these bugs; the symptoms of an allergic reaction can include a rash, asthma, itchy eyes, and a sore throat.
Over 4,000 species exist worldwide, with one species or another either creeping around in your basement, flying right at you, dropping on you from trees and ceilings in the dark of night or others scattering in throngs of thousands, when caught invading your kitchen, cockroaches are one of our most terrifying pests.
With Halloween just around the corner, its time for larger-than-life creepy, crawly creatures skittering across lawns, lurking in dark alleyways and dropping out of nowhere to frighten their hapless victims.
