Tips and recommendations


One of the problems that arise when we suffer from a pest of cockroaches is that many diseases can be traveling with them. By feeding in dirty places they are the perfect carriers for transmitting bacteria, viruses, protozoa and fungi to people.

The Public Health Agency of the Barcelona Health Consortium considers cockroaches as "one of the main vectors of disease transmission in humans."

The american cockroach It usually comes from sewage and can be found in commercial buildings, ovens and establishments where food is handled. The german cockroach He prefers hot and humid places like garbage cans, kitchens and bathrooms.

How can cockroaches infect us?

Cockroaches carry a multitude of allergens in your body or in your droppings. These are capable of causing diseases such as hives, sneezing and severe tearing in sensitive people.

We offer a list of diseases that cockroaches can transmit to us:

  • Salmonella
  • Stomach flu
  • Child diarrhea
  • Asthma
  • Hepatitis
  • Urinary infection
  • Dermatitis

A study of National Institute of Environmental Health Sciences (NIEHS) and the National Institute of Allergy and Contagious Diseases US reveals an alarming fact:

Allergens from cockroaches are among the factors that predispose or worsen cases of childhood asthma in cities.

However, a survey of the National Pest Management Association (NPMA) Remember that only 10% of the inhabitants perceived cockroaches as a threat to the health of their family.

Cockroaches usually access homes and / or businesses in search of shelter and food. They have a preference for food rich in starch, fats and sugars, although they can eat leather and glue. Researchers of the Tohoku University They discovered that these insects associate the smell of vanilla and mint with sugar.

Cockroaches are like a disease bus, their bodies are full of small fissures and hairs that are perfect for transporting all kinds of microorganisms, while offering a perfect environment for them to live and reproduce. This constant traffic between feces and food causes cockroaches to release and collect a large number of viruses, parasites and pathogens on your route Unlike mosquitoes, which act as a disease vector, infecting people in their search for blood, cockroaches are what entomologists call "Mechanical transmitters". This means that cockroaches are a Deposit indiscriminate of all types of passengers, which pollute where they pass.

Control the cockroach pest in your home, or it can trigger a major problem.


This disease basically consists of bowel inflammation, normally the colon, causing stomach aches and diarrhea. The severity of symptoms may vary depending on the pathogen that causes it.

Cholera is caused by a type of bacteria called Vibrio cholerae, which is usually found in cockroaches. It mostly consists of inflammation of the small intestine, which triggers stomach ache and diarrhea, although some people suffer from few symptoms or even none at all.

Leprosy is caused by another passenger who can be found cockroaches, Mycobacterium leprae. This bad guy causes terrible skin sores, which, if left untreated, can trigger severe disfigurements, as well as cause nerve damage of the limbs.

Typhoid fever

Typhoid fever is an infection caused by Salmonella typhi, or its cousin the Salmonella paratyphi, which normally causes a mild version of the disease, and usually transmits by arrival bodies from cockroaches to water and food sources. The most common symptoms include high fevers, discomfort and pain, diarrhea and lethargy.


One of the viruses that have been observed in cockroaches is Poliomyelitis, more commonly known as Polio, which is a severe disease that mostly affects children under three years. A person infected with the virus may suffer fevers, fatigue, stiff neck and, if the virus invades the nervous systemparalysis

Other regular passengers

It has been observed that cockroaches also carry at least 6 other parasites, including those of the giant worm, caterpillar worm and hookworm. At the same time it has been found that they carry latent eggs of parasites such as those of Escherichia coli, C. parvum, C. cayetanensis and Entamoeba histolytica. These parasites may have serious effects on human healthThey can cause intestinal damage, liver damage or diarrhea, as well as other diseases.

It is a commonly known fact that cockroaches are also the cause of asthma and allergies, especially in children. Their droppings and other debris that fall to the ground are so small that they are easily collected through the air in the same way that dust is, and inhaled by humans. As soon as we breathe those particles, they are deposited in our bronchi and detected by our immune system, causing allergic reactions known as asthma.

Now that we have some notions about how harmful our well-being is for our house to house cockroaches, we know that we must act quickly if we detect a cockroach walking along the wall. When we decide to take part in the matter, we must keep in mind that we will never know how many cockroaches are there really, or if they have the nest nearby. For that reason Cucal cockroach traps has been developed to kill, not only those cockroaches that come in contact with the gel, but also those that come into contact with them when they return to the nest. In this way, we can make sure that our house stops being a cockroach season.

Diseases that transmit cockroaches

The cockroaches They are carriers of numerous bacteria that are harmful to humans, it is known through studies that the bacteria are on their body and with the simple fact of passing through a place, it is being contaminated by some of these bacteria .

Among the diseases that cause cockroaches They are: bubonic plague, childhood diarrhea infections in the intestine, dysentery, urinary infections, leprosy, gastroenteritis, inflammation and infections with pus, typhoid and enteric fevers.

There are some studies that show that cockroaches can maintain, acquire and excrete a virus, in addition there are problems due to the contact of cockroaches With the human being it is the case of dermatitis, edemas in the eyelids, tearing of the eyes, sneezing among others.

Likewise, this small insect has been identified as the cause of numerous allergies that are in the dust of the house. It is important that in order for us to reduce and eliminate this insect we must keep our house clean, all the holes in the walls where a cockroach can be placed or hidden, in this way we contribute to the prevention of the proliferation of this insect.

Although it seems a lie we should not ignore this plague and much less if there are children in our home so it is recommended to fight this pest before it proliferates, do not neglect, prevention is the best way to eliminate them from the house.

Cockroach diseases

In general, the list of pathologies associated with the bacteria transmitted by cockroaches can be found:

  • salmonellosis,
  • Infectious hepatitis
  • Leprosy
  • The bubonic plague
  • Dysentery
  • Childhood diarrhea
  • Urinary or bowel infections
  • Inflammation and abscesses of pus
  • Stomach flu
  • Enteric and typhoid fevers

Similarly, cockroach secretions can trigger allergic reactions of varying intensity, with symptoms of tearing, swelling of the face, dermatitis and even asthma.

Others pathogens that transmit cockroaches are the virusCoxsackie, the encephalitis virus and the yellow fever virus. Waves bacteria cholera, diphtheria, tuberculosis, among others, or protozoa such as trichomonas, giardia lamdia or balantidium, which produce diarrhea or dysentery.

Eating food contaminated by cockroaches is one of the routes of infection, as well as contact when handling these animals or after receiving their bite.

Those allergic to their secretions, meanwhile, are triggered by simple inhalation of their secretions. It is also problematic if cockroaches eat cat droppings infested with toxoplasma gondii, a protozoan that causes the dreaded toxoplasmosis.

The favorite time of cockroaches is in summer. To reduce risks and prevent disease transmission, a pest control. Eradicating them is difficult without the action of professionals who manage to solve the problem, if possible without using chemicals.

Cockroach diseases

Unlike mosquitoes and ticks, which cause disease in humans and animals directly through their bites, cockroaches only cause diseases indirectly. Like houseflies, cockroaches spread germs that can cause certain diseases due to their dirty habits.

Cockroaches act as deposits of bacteria. The places they visit, such as sewers and litter bins, as well as eating raw meat and animal feces, mean they can accumulate bacteria easily and frequently.

These are some examples of diseases and infections that cockroaches spread: E. Coli, Salmonella, Typhoid Fever, Staphylococcus and Streptococcus, Cholera, Gastroenteritis, Dysentery and Leprosy.

Cockroaches and asthma

Apart from diseases such as those mentioned above, these creeping insects can cause asthma. Cockroaches have certain proteins in their bodies that can be an allergen for certain people.

When tiny particles of cockroach bodies expand through the air in closed buildings, these proteins, when inhaled, can cause an asthma attack in sensitive people.

The American College of Allergy, Asthma and Immunology ensures that saliva, feces and skin of cockroach molts can trigger asthma and other allergies.

The National Pest Management Association, in the US, has conducted studies on cockroach and residential allergens. His studies show that about 63% of households in the US They contain allergens. This statistic increases for households in urban areas (between 78% and 98%).

How do cockroaches spread diseases?

So how do cockroaches spread disease?

There are several ways in which cockroaches can spread disease: through their vomiting, feces, or through direct contact.

When a cockroach feeds on something that contains bacteria such as a raw piece of chicken, or animal feces, the bacteria will enter its system by staying inside its mouth, in its saliva, and even inactive in its digestive system.

When they vomit or defecate, the bacteria can contaminate the place or food where they are deposited.

Moreover, during their transits and while they are feeding they come into contact with dirt, which contains germs, and which they then carry in their body. Think of cockroaches as giant magnets for bacteria and viruses! These germs are deposited in any place where they pass and with which they have contact.

How do cockroaches infect us?

It is quite simple, we can get a disease just by eating or drinking anything where the cockroach has vomited, defecated or even where it has walked.

Similarly, if you have used any kitchen appliance or utensil to eat such as a cup or plate that has been contaminated by cockroach droppings, there may be a risk of getting sick. The same goes for dishcloths and dirty towels.

For asthmatics, the presence of cockroaches in your home or workplace can lead to an asthma attack or other allergic reactions.

As I have already told you, the skin of cockroaches, saliva and feces contains all the proteins that trigger asthma, so the risk exists only with the fact of being in an area and breathing where these substances have been mixed with the air.

How to prevent cockroach diseases

The best way to prevent cockroach diseases is to apply good food hygiene practices.

Properly cooking food before eating, washing raw ingredients, as well as regularly cleaning cutlery, cooking utensils and dishes can help eliminate any bacteria and viruses that a cockroach may have left.

As for business, good practices to prevent diseases that cockroaches can spread come hand in hand with compliance with the correct food safety standards and regulations for each country.

There are specific rules and regulations that help limit the spread of bacteria by cockroaches, and other pests, to ensure that the food produced is safe for human consumption, and the risk of foodborne illness is kept to a minimum.
