Are Roaches Dangerous? 5 Reasons That Prove How Dangerous They Are

So you’ve found a cockroach in your home, and you aren’t sure just how dangerous they are, bringing you here to our site. Cockroaches aren’t only annoying, but they carry harmful bacteria that can be bad for humans. Read on to find out why it’s important to fend these annoying pests off for good.

Humans have long been afraid of roaches. But sometimes, a lot of us don’t even know why. Is it because of how they look? Of what they eat? Is it because they are nocturnal, afraid of the light, sneaking around when we least expect it? Or are roaches actually dangerous?

Most people don’t like roaches around their home, just because of the stigma that comes with it. We often think of homes with roaches to be unsanitary, or dirty. The truth is, these bugs are actually more dangerous than other pests.

And it’s definitely not because of their look. It’s because of what they carry. These annoying pests carry many different bacteria that can be harmful to humans. So if you’re wondering what these bugs can do, here are 5 reasons that prove how dangerous they can be.

Roaches Contaminate Food With Disease-causing Bacteria

Ecoli Bacteria
Roaches carry harmful bacteria, like E. Coli which is very dangerous to humans.

Roaches can contaminate the things we eat. Aside from striking fear and disgust into almost every human they can find, roaches are known for contaminating food.

Cockroaches will crawl around your house looking for something to eat. So if you leave food out in the open, it’ll get to it and contaminate it.

First, it will soil the food with its droppings. Roaches have a bad habit of defecating on what they eat. They also leave behind tiny hair, dead skin and egg shells.

Second, a cockroach eats fecal matter from other animals. So it picks up bacteria from what it feeds on and passes them into anything it touches. Here are a few of the most common bacteria that a cockroach can put into your food.

E. Coli

Don’t get us wrong, this bacteria already lives in our digestive tract. But the type that we have are harmless.

For roaches, however, they can harbor harmful types of E. Coli, and they can spread them across the house. If these bacteria get into a person’s body, they will cause serious food poisoning which will take about 1 to 2 weeks to get better with proper treatment.

Salmonella

Another bacteria that you can get from roaches is Salmonella. This type of bacteria can also cause food poisoning. In the US alone, there are about 50,000 cases of Salmonella infections each year.

People infected by this will experience diarrhea, fever and abdominal cramps. They will need to be hospitalized to receive proper care and treatment.

They Cause Allergies

Roaches can cause allergic reactions in sensitive individuals.

Roaches only bite humans if they really need to. Similar to other bugs, they bite when they sense that they need to defend themselves, like when they’re pinned down. They can also bite human flesh when their population has become so big that food has become scarce.

The scary thing about these roach bites are not the bites themselves. It’s what comes after them. If a bacterial infection does not get you, maybe an allergic reaction will.

According to a publication by the World Health Organization, cockroaches carry parasitic worms that can cause allergies, but they’re saliva alone is enough to trigger reactions like skin rashes, welts, sneezing, watery eyes and even difficulty in breathing.

They Trigger Asthma

Roaches can trigger asthma in sensitive individuals.

Since roaches can trigger allergies, it’s only natural that they can also cause asthma in individuals with certain sensitivities.

The same substances can trigger both medical conditions. In fact, incidences of getting an asthma attack may increase if you live in a house full of roaches. According to Rentokil, 23-60% of asthma sufferers are sensitive to cockroach allergens.

So we highly recommend getting rid of roaches immediately if you have a loved one that has asthma.

They Can Try To Get Inside Your Body

While unlikely, it is possible for roaches to find their way inside your ear or nose while you sleep.

It’s the stuff of nightmares. Bizzare, unrealistic and even crazy, you might be thinking that it’s fictional. But incidents with roaches getting inside human body parts are more common than you think.

This is not surprising since emergency rooms in big cities get visits from patients with roaches inside their ears. Homes with huge cockroach populations force roaches to travel to more dark corners and holes to look for food. And unfortunately, our ears and noses are those “dark holes” that they can fit into.

Having these insects inside you can cause great pain, unbearable discomfort and an itching feeling that’s literally under your skin. If left untreated, the roach can die inside and cause a severe infection.

They Can Cause Diseases

Disease Causing Roach
Roaches can help spread many other diseases you may not be aware of.

We put this in the last part because although roaches have always been seen as dirty and disease-causing for many years, there’s actually little evidence that links them to disease outbreaks.

But this doesn’t mean that they don’t carry other deadly illnesses. The earlier mentioned publication from the World Health Organization further states that roaches can play a supplementary role in spreading diseases like cholera, diarrhea, dysentery, the plague, leprosy, typhoid fever, and viral diseases like poliomyelitis.

So are roaches really dangerous? Well since they cause a number of serious medical conditions, we think it’s only fair for humans to be afraid of them. For many of these illnesses, lives are at stake. So this fear keeps us in check. It gives us a few good reasons to get rid of these bugs now.
