Bed Bugs: Can They Transmit Disease?

Most people associate bed bugs with seedy motel rooms, dirty linens, and scores of red, puffy, itchy bites. In addition, though, it’s commonly believed that bed bugs are dangerous to your health. Much as with ticks and Lyme disease, many people think of bed bugs as a disease vector. If you’ve brought them home with you from a night in an infested hotel or house, you might be worried about the potential of contracting some kind of illness.

Let’s take a look at some of the facts and fictions surrounding bed bugs and disease. Then, we’ll move on to what you can do in terms of home pest control to take care of bed bugs once and for all.

Bed Bugs and Diseases

First things first: up until very recently, bed bugs weren’t scientifically proven to carry any sort of transmittable disease. While popular belief might associate them with serious illnesses (much like rats and the plague, or ticks and Lyme disease), the CDC had concluded that they couldn’t actually carry any illness that can be passed along to humans.

Of course, this doesn’t preclude the possibility of serious complications from bed bug bites. In some people, symptoms are very mild: a person might have a slight reaction to a bed bug bite that involves a minor amount of itching. In certain segments of the population, though, bites from bed bugs can cause a serious allergic reaction. If you believe you’re experiencing a reaction to bed bug bites, it’s important to seek medical assistance immediately.

Chagas Disease

More recently, researchers have discovered new information regarding bed bugs and disease. According to a 2014 study conducted by the Center for Clinical Epidemiology and Biostatistics at Penn State University’s School of Medicine, bed bugs are actually capable of transmitting a parasite known as Trypanosoma cruzi. This parasite in turn causes something called Chagas disease, which is one of the most deadly illnesses in Central and South America.

Chagas impacts over 6 million people per year around the world, and results in the death of roughly 50,000 people annually. However, bed bugs don’t spread the infection with their bite. Instead, the parasite is carried in their feces.

How Bed Bugs Transmit Chagas

After feeding on a sleeping host, bed bugs will often deposit feces onto the host themselves. This sometimes happens on and around the face, which means the potential of transmitting Chagas is very real. Recently, Dr. Michael Z. Levy at the University of Pennsylvania’s Perelman School of Medicine managed to demonstrate that bed bugs can pass the Trypanosoma cruzi parasite on to mice in a controlled experimental environment.

Chagas disease is sometimes called a “silent killer,” due to the fact that it’s hard to recognize any symptoms while the disease is in its earliest stages. Over time, Chagas can lead to heart problems, digestive upset, and even neurological issues.

Other Potential Bed Bug Diseases

In addition to Chagas, some sources have argued that bed bugs are capable of spreading other diseases as well, including oriental sores, brucellosis, and even leprosy. There doesn’t appear to be any proof to back up these claims as of right now. Keep in mind, though, that the discovery of bed bugs’ ability to transmit Chagas is a very recent finding. New information may come to light in the future.

When to See a Doctor

As mentioned above, bed bugs don’t have to transmit disease in order to pose a potentially serious health hazard. If you think you’ve been bitten by bed bugs and feel that you’re experiencing any symptoms indicative of an allergic reaction, it’s important to contact a doctor right away.

Additionally, if you’re suffering from any unusual symptoms that you believe could be connected to a disease or disorder of some kind, don’t hesitate to contact a medical professional.

Eliminating Bed Bugs

Even if you’re not experiencing serious symptoms as the result of a bed bug infestation, there’s no doubt about it: bed bugs are an awful pest to have in your home.

Eliminating them once and for all can be challenging, though. If you’re dealing with bed bugs, we highly recommend contacting Home Pest Control for a consultation. We offer safe, environmentally-friendly pest services designed to help you get rid of bed bugs fast.

Are Bed Bugs Dangerous? Bed Bug Diseases

Bed bugs are small, brownish and wingless insects about the size of an apple seed that feed on blood of warm blooded animals such as cats, dogs, rodents and birds. Humans are considered warm blooded too, therefore humans are also ideal hosts for these bed bugs. The common bed bugs are scientifically called Cimex Lectularius and these insects are actually called bed bugs because of the places they prefer to live in inside some people’s homes; they prefer to live on bed mattresses, beddings, even on sofas and other soft home furniture.

Bed bugs originally infest nest of animals such as birds, but over time, they have learned to adapt and infest places or homes for humans such as homes, dormitories, hotels, barracks and so on, most especially the common bed bugs which has learned to adapt to human environment. They can infest a certain area by being transported, attaching themselves on luggage, furniture or bedding moved to a new area. They can also be transported by animals such as birds or bats flying to a home. Bed bugs can move from one place to another through tubes and holes.

Bed bugs are visible to the naked eye, may it be the nymph form, egg and adult stage of bed bugs. Nymph stage of bed bugs appears as whitish-yellow and translucent and turns reddish because of the recent blood feeding. Adult bed bugs are usually flat, but inflate and elongate after feeding. The peak time of bed bug feeding is about an hour before sunrise, bed bugs are most especially active that time. However, bed bugs will take the opportunity to feed whenever available and whenever they are hungry at any time of the day or night. They get to their animal or human host by crawling towards it, attracted to the heat or warmth of the host and the presence of carbon dioxide. Bug bites that occurred while sleeping are signs of having bed bugs in the area. Bed bug bites appear as red bumps of the skin in rows of two to four bites, which are really itchy. Bed bug bites are commonly found in the neck, back, face, shoulders, arms and legs. It is important to detect a bed bug infestation early in order to prevent it from becoming worse.

Dangers of Bed Bug Bites

Some people may wonder, “Are bed bugs dangerous?” Actually, bed bug bites are not hazardous to health. If bed bugs feed on one particular human host over a period of time, like several weeks for instance, the human becomes more sensitive to the bed bugs’ saliva, leading to an allergic reaction. However, not all people develop an allergic reaction to bed bug bites. Bed bugs inject a small amount of saliva when feeding, which usually takes minutes; this saliva contains anesthetics which is responsible for the painless bites and also contains anticoagulants so that blood will continuously flow. The only slight risk a human may experience from a bed bug bite is when that certain person develops a mild to severe allergic reaction to the bed bug bite. Fortunately, medications are available in treating the allergic reaction, such as corticosteroids or antihistamine medications.

Bed Bug Diseases

Bed bug may seem like a dangerous kind of biting insect because they feed on both animal and human blood. In fact, bed bugs carry diseases and other pathogens inside them and around their mouth area. However, they are not known to cause bed bug diseases, and are not proven to transmit diseases to humans. Scientific tests have been performed and have concluded that bed bugs are merely nuisance rather than health risks to humans and are unlikely to transmit bed bug diseases from one host to another. Another thing humans can experience from bed bug bites is the risk of a secondary infection due to intense scratching of the itchy bed bug bites. Scratching will cause the skin to break, allowing entry for bacteria – however these infection causing bacteria are not from the bed bugs.

Health experts say that bed bug infestations may cause an added stress to people causing noteworthy impact to the welfare and emotion of some people as these bed bugs may cause discomfort, anxiety, not enough sleep or even embarrassment.

What’s stopping me?

Can it all go wrong?

Is it dangerous to eat insects?

Of course, some insects are poisonous. The key thing is to know what you’re eating, and where it’s come from.

With meat and seafood, it’s worth bearing in mind that you’re almost always taking a risk. You can know the animal is an edible one; you can buy it from a ‘proper shop’ – but the scale of industrial farming means that meat, especially cheap stuff, is dangerous; particularly worrying are the antibiotics that pigs and other animals are pumped full of in large industrial farms. This is to stop the filthy and painful conditions in these places from literally killing the animals – and it means antibiotic resistance is rising among humans.

One benefit of insects as a food source is their genetic dissimilarity from humans.

Then there’s the sewage produced by massive livestock farms and abattoirs. Nitrate levels in groundwater can be affected, causing severe health problems in infants and pregnant women. Pathogenic bacteria (the ones which cause illness) are prevalent in livestock sewage: things like MRSA, listeria and salmonella. Regulators try to regulate and contain these problems, but with livestock farming reaching such huge concentrations, the contamination risks are huge. Arguably, we’re in danger of poisoning ourselves by producing and eating meat in this way.

This could be seen as an argument for a much more humane, less intensive meat production system, and makes the case for insects as better food source. Unfortunately, just like pesticide use, intensive meat farming has an effect on the safety of entomophagy too. The idea of feeding animals on insects, which themselves are fed on such organic waste, raises the question that insects could be contaminated by the same bacteria and toxins as the animals. Research is ongoing by EU bodies, but the latest report noted that farming insects poses no greater risk than farming livestock.

Arachnids like scorpions are closely related to crustaceans and shellfish. They taste and look similar — and carry similar risks.

One benefit of insects as a food source is their genetic dissimilarity from humans. Swine and avian flu pose significant threats to humans because the genetic similarities with humans allow the diseases to ‘jump’ across and mutate. Insects, though, are genetically very distant from us.

Seafood is also risky. All those shellfish food poisoning incidences? Not surprising, as some shellfish are filter-feeders, so toxins naturally build up in their flesh. There are regulations to try and mitigate this, but it’s a natural occurrence. Lobsters and crabs crawl along the bottom of the ocean eating anything and everything, dead or alive, that comes their way. Nice. No wonder they can give you a dodgy tummy.

Their land-based cousins, however, are much cleaner eaters. Scorpions and spiders are actually said to taste a little like crab and lobster, but the only danger is in the venom sacs which you can just neatly cut off, as bug chef David George Gordon helpfully demonstrates in this video. Venom actually becomes safe when cooked, turning solid much like an egg white does, so even this can be eaten if you follow the advice.

Of course some edible insects are also ‘detritivores’ — meaning that they eat decaying matter. Dung beetles, burying beetles and woodlice all do this. Such species play an important part in the ecosystem, but as with filter-feeding shellfish, they could cause illness. Precaution and research is important.

Essentially, any food has a variety of risks associated with it.

Allergies are also something to consider. Again, insects are not unusual in this respect, as any protein-containing food has the potential to trigger an allergic reaction. Scorpions are actually closely related to crustaceans and shellfish, which is why they taste and look similar. So if you’re allergic to the proteins in shellfish, exercise caution.

Sadly pesticide and herbicide use is extremely widespread, causing damage to animals, humans and insects alike. Some insects can tolerate higher levels of heavy metal contamination than mammals, meaning arsenic and lead poisoning are a slightly higher risk when eating insects. It’s still a very minimal risk, but it indicates the bigger problem: our food production, from the chemical sprays to the medicated, hormone-pumped feed and industrial-scale slaughter, is toxic – not just for human health but for the whole ecology, and insects are just as affected.

Essentially, any food has a variety of risks associated with it. With insects, the risks are estimated to be relatively small, and easily controlled.
