How Can Cockroaches Affect Your Health

It is not a secret your health is your biggest asset. With that said, there is no doubt most people treasure it greatly, and don’t take matters relating to health for granted. While the public pays extreme attention to well publicised facts that can affect health, sadly many overlook some less popular beliefs. Pests are a major source of concern in many homes not only in Australia, but also in all other countries around the world. Although every homeowner makes a conscious effort to deal with this problem, some pests are not as easy to eradicate as it seems. Some cockroach species belong to this category of pests. They are those small brown insects often found running across the floor of your home. You might wonder how these seemingly harmless looking bugs can pose such a great threat to your health?

The answer to this lies in their anatomy and feeding habits.

How Do Cockroaches Spread Diseases?


Cockroaches are most active at night and feed on any organic material. While searching for food they come in contact with bacteria which can cause debilitating illnesses and affect the health of humans. These microbes and pathogens can be transmitted to humans when contaminated food and water is consumed and contaminated utensils are used.

Cockroaches are also linked to allergic reactions. Their saliva, faeces and shedding body parts contain certain proteins which can cause serious health problems by triggering or worsening asthmatic attacks. Cockroaches are attracted to warm and humid places. Unfortunately the ear satisfies the prerequisites for a cockroach haven, in fact scientists have proven that ear wax also attracts cockroaches. This is why cockroaches can crawl up into the ear and cause ear infection or hearing loss.
