Which of the following is true about allergens produced by cockroaches?

1. They are harmless to humans

2. They can become airborne when disturbed

3. They are only found in food sources

4. They are easy to clean up

The correct answer is: They can become airborne when disturbed

Cockroach allergens are a significant concern in public health, particularly for individuals with asthma or allergies. The correct assertion is that these allergens can become airborne when disturbed. This is crucial because when a cockroach is crushed or when its droppings are agitated, microscopic particles that contain allergens can be released into the air. This can lead to respiratory issues for sensitive individuals, as inhalation of these allergens can trigger allergic reactions or asthma attacks. Understanding why cockroach allergens can become airborne highlights the importance of managing environments where cockroaches are present. Effective pest management strategies often involve not only reducing the cockroach population but also minimizing the risk of allergen exposure through proper cleaning and maintenance. The other options do not accurately describe the nature of cockroach allergens. For instance, these allergens can be harmful, especially to individuals with pre-existing conditions. They are not exclusively found in food sources; instead, they can be present in other areas where cockroaches inhabit, such as hiding spaces and surfaces. Finally, while cleaning can reduce the presence of allergens, it is often not considered easy due to the need for thorough and consistent methods to effectively eliminate them from the environment.
