Quite possibly one of the most disgusting pests known to man, cockroaches are known to inhabit in filthy environments and emit an offensive odor.  

Cockroaches are ancient creatures, having originated more than 280 million years ago, pre-dating even the dinosaurs. The fact that they have survived all these years just goes to show how hardy and resilient they are. 

Cockroaches belong to the insect Order Blattodea, along with termites. Of the 4000 species of cockroaches, only a few are considered pests as they invade, inhabit, and (quite possibly) infest human dwellings. 

In the United States, the two most common cockroach pest species are the American cockroach and the German cockroach. 

The reddish-brown American cockroach seems to be strongly attracted to alcoholic beverages– stale beer, in particular. When outdoors, they prefer garbage heaps and mulch. When indoors, this variety of cockroach favors dark, warm, and moist areas like basements, bathrooms, drainages, laundry rooms, and other crawl spaces. 

The slightly smaller, light brown German cockroaches have wings but rarely fly. These are associated in particular with restaurants, food processing facilities, hotels, nursing homes, and other institutions. When excited or frightened, German cockroaches are known to emit a foul odor. 

What Makes Cockroaches So Hard To Kill? 

A study published by UC-Berkeley researchers has found that one of the reasons why cockroaches are so durable is because of how its exoskeleton is built. 

A cockroach has overlapping plates connected by a stretchy membrane that somehow makes it resistant to crushing damage, and gives it the ability to somehow navigate through cracks and other tight spaces. 

Also, cockroaches eat just about anything, including cardboard boxes, bookbinding, and even human nail clippings if regular food just isn’t available. 

They also have incredible immune systems, have shown some resistance to more common pesticides and roach-killers, and can even survive up to 18 days without food. 

What Kinds of Diseases Can I Get From Cockroaches? 

The World Health Organization points out that cockroaches can sometimes play a role as carriers of intestinal diseases and illness-causing pathogens like E. coli and salmonella.  

As cockroaches are more commonly found in and around areas where waste is disposed, these pests can carry serious diseases such as diarrhea, dysentery, typhoid fever, and cholera, among  

Cockroaches then hang out in the kitchen or food preparation areas where food is present, potentially spreading their diseases or pathogens in our food and utensils. 

In addition, cockroaches frequently cast off debris and droppings, and along with other dead roach bodies, these can potentially aggravate allergies or cause asthma, especially in little children or sensitive individuals. 

How Do I Know If I Have a Cockroach Infestation? 

Because cockroaches are typically active at night, the very few cockroaches you may see by day could mean they were likely forced out by overcrowding. 

This means there’s a thriving population of cockroaches nearby, and quite possibly an infestation in your premises.
