Can Cockroaches Affect Your Health?


Not only can the infestation of pests in your home cause disturbing damage, but the potential health risks involved are alarming. Although homeowners are sensible and aware of this problem, the best course of action needs to be taken to eradicate the pests.

Cockroaches are small brown bugs, running around your floors, invading every possible opening, cracks and crevice. Cockroaches are known to carry bacteria that can cause serious illness.


Cockroaches are more active at night, in search of food. As they feed off organisms, bacteria is ingested and can stay dormant in their digestive system for months or even years. This will pass in the contaminated droppings or by vomiting on food. Microorganisms and pathogens are transmitted when water and food are consumed as well as infected utensils.

The proteins in cockroaches which contain enzymes are linked to allergic reactions and can trigger or worsen asthma. These proteins are found in the saliva, excrement and shedding of body parts. This spreads easily and rapidly throughout the house.

Cockroaches thrive in small, warm, humid places. Scientists have proven that the ear and the smell of earwax, stimulate and attracts them. Once they crawl inside the ear, it is likely for them to get stuck and cause ear infection or loss of hearing.


Cockroaches carry germs and spread a range of serious diseases as they move very quickly. They usually breed in outdoor drains, sewer pipes and garbage bins.

The increased surface area on their legs is known to gather germs and transmit diseases.

Cockroaches are filthy household pests that have many negative consequences on our health. The substances they produce can trigger asthma attacks and lead to respiratory diseases and narrowing of airways, which can be detrimental to our health.

Cockroaches are suspected carrier of Diarrhea, Plague, Typhoid fever, Leprosy, Dysentery, Cholera, Shigellosis, Gastroenteritis, Hepatitis A, Listeriosis, Beaver Fever, Dermatitis and viral diseases such as Poliomyelitis.


The most effective way to prevent the spread of diseases in your home or business, is to decrease the possibility of these crawling bugs entering the household and spreading unwanted diseases which are harmful to our health. Once a cockroach infestation has occurred, it is not easy to get rid of the pest.
