Are Allergies Related to Household Pests?

Posted by:

When people sneeze and suffer from runny nose during the spring seasons, they blame it on the pollen and grass. However, common household pests such as cockroaches can also be a potential cause of allergies and increased asthma symptoms. Other insects such as bees and wasps also pose a significant threat due to serious allergic reactions from the pests’ sting venom.

According to recent studies, cockroaches, one of the most common household pests, carry allergens that can cause skin rashes, stuffy nose, itchy eyes, and acute asthma attacks. Cockroach droppings, saliva, and other body parts contain allergen protein that causes allergic reactions especially in young children.

Signs and Symptoms of Cockroach Allergy

The signs and symptoms of cockroach allergy may include a chronic stuffy nose, a persistent skin rash, and an all-year round asthma symptoms such as coughing, wheezing, shortness of breath, and tightness in the chest. If you or any of your family members are suffering from these symptoms, it is imperative to consult your doctor. If cockroach allergy is diagnosed, it is essential to take preventive measures and keep your home cockroach-free.

Asthma Attacks and Cockroach Allergen

Asthma is a serious and sometimes life-threatening disease characterized by inflammation of the bronchial tubes. Individuals with asthma experience shortness of breath when their airways tighten or fill with mucus. Common symptoms also include coughing, especially during the night, wheezing, and shortness of breath.

Studies have shown that asthmatic children that are exposed to cockroach allergens are more prone to experience coughing, wheezing, and unexpected medical visits and hospitalizations due to asthma attacks. Cockroaches, whether alive or dead, poses a major health risk to people who are sensitive to allergens. Every part of the cockroach’s body including their saliva and urine can become part of the house dust and may cause allergic reactions.

It is also important to see your doctor regularly especially when you are suffering from allergy or asthma symptoms.

Your doctor may prescribe the use of antihistamine and anti-inflammatory drugs to ease the symptoms.
