Many articles devoted to the dangers of living in the same room with cockroaches focus on their ability to carry many dangerous diseases. However, it is also worth considering the issue of allergic reactions caused by cockroaches. Can the presence of cockroaches make allergies worse or even contribute to their development, especially if the allergy has not previously been observed?

Scientific research suggests that cockroaches can actually affect human health in the allergic aspect. They produce proteins that can be allergenic and cause allergic reactions in people. The presence of these proteins in the air can lead to the development of allergies in people, even if they have not previously had such manifestations.

In addition, cockroach feces and body debris may contain allergens that, when dispersed throughout the environment, can worsen existing allergies or cause new allergic reactions.

Thus, not only do cockroaches pose a health threat as carriers of disease, but their effect on allergies should be considered as an additional aspect of the negative impact on human health.

Do cockroaches cause allergies? 

Domestic cockroaches belong to the category of synanthropic insects that have successfully adapted to their proximity to humans. Along with fleas, bedbugs, flies and ants, they have found ways to search for food in various environments, be it residential or commercial, and easily benefit from the forced proximity to people, providing themselves with access to food, water and warmth. Cockroaches, on their legs and shell, carry a significant number of pathogens, and more than 40 types of bacteria have been found in their saliva, including salmonella and shigella, which causes dysentery. Additionally, the danger is posed by the waste that cockroaches leave everywhere.

Cockroaches can cause an allergic reaction. When a large number of cockroaches live in an apartment, the remains of chitinous cover, egg capsules, excrement, and mold spores accumulate, which, together with household dust, can enter the human respiratory tract. This can cause coughing, nasal congestion and itchy skin - typical allergy symptoms.

Interestingly, like dust mite allergies, cockroach allergy symptoms are aggravated by dry cleaning or prolonged exposure to unventilated areas.

Another interesting fact: theoretically, cockroaches can infect a person through a bite. Although such cases are rare, they are still possible.

Can cockroaches cause allergies if there were none before?

This issue is controversial, since only a few can boast of a complete absence of allergic reactions. The main difficulty is that we often do not know enough about our allergic profile and, therefore, may not be aware of the presence of reactions to various allergens. However, there is a fact that deserves attention: 50% of asthmatics living in cities have antibodies in their blood that indicate an allergic reaction to cockroach protein.

In other words, if you have a predisposition to allergies, the presence of cockroaches in your home can easily aggravate this process and lead to various complications such as asthma, bronchitis and severe allergic rhinitis. Considering that cockroaches produce allergenic proteins and their presence can significantly enhance human reactions to allergens, the control of these insects becomes an important point in maintaining the health of people, especially those who are susceptible to allergic manifestations.

Is there an allergy specifically to cockroaches?

Of course, such a problem exists. According to epidemiological data, up to 60–70% of the urban population is susceptible to allergic reactions to cockroaches. The risk is especially high for those who already have a history of asthma, chronic bronchitis or rhinitis.

You can confirm the presence of an allergy to cockroaches by contacting an allergist, who will perform the necessary skin tests or suggest antibody tests. If an allergy is confirmed, immediate cleaning of the apartment from cockroaches becomes an important step in managing this disease. For those already at risk due to pre-existing allergic conditions, proactive measures to prevent exposure to cockroaches can significantly improve quality of life and health.

How to get rid of cockroaches and stop suffering from allergies?

Control and prevention: have you found one cockroach and are you sure that it is an accidental invader? This is false confidence because cockroaches reproduce at an astonishing rate. So it’s important to react urgently and take action.

Maintain cleanliness: Avoid leaving leftover food and dishes in the sink as this is an ideal invitation for cockroaches. It's important to remember that cockroaches can enter your home from a variety of sources, so keeping it clean isn't always a guarantee against these uninvited guests.

Timely pest control: Although you can try to deal with the problem yourself using traps, household products or popular insecticides, professional treatment for cockroaches is usually more effective. Reliable professionals can apply effective methods to provide long-term protection against insects and prevent re-infestation.
