Top Diseases Cockroaches Carry

The presence of cockroaches indicates that a space is unhygenic, dirty and filthy. Cockroaches can easily ingest and carry various types of pathogenic microorganisms on their bodies such as bacteria, viruses, fungi or parasites. These substances can contaminate food, surfaces and packaging, and spread illnesses or spoil food products.

As most of these critters hide away in warm and unseen environments such as the back of a refrigerator, unbeknownst to you, your new condo could be a breeding spot for these pests until much later when you accidentally forget to clear dropped pieces of food in your dustbin, and one or two decide to surprise you. 

Diseases that cockroaches carry 

Cockroaches can transmit diseases indirectly by contaminating items through touch. Cockroaches are proven or suspected carriers of the following infections: 

  • Salmonellosis
  • Typhoid Fever
  • Cholera
  • Shigellosis
  • Polio
  • Gastroenteritis/Dysentery
  • Leprosy 
  • Plague 
  • Campylobacteriosis
  • Listeriosis
  • E.coli infections

Cockroaches feed on contaminated food and accumulate bacteria in their digestive systems for a month or longer before depositing it through their vomit and feces. These diseases are then transmitted through the consumption of contaminated food items. Most of the symptoms include diarrhoea, fever, vomiting, high fever, head and muscle aches, constipation, painful stomach cramps and nausea. 

Despite being more common in developing countries with poor sanitation and limited access to clean waters, it is safer to be aware of the severity of the diseases cockroaches can carry and transmit to you in the case of a horrid infestation. 

How can you catch a disease from a cockroach? 

The most common form is from eating or drinking anything that the cockroach has contaminated. Other than food, contaminated cooking utensils, cutlery or touched surfaces are also potential sources. 

The air supply can also be contaminated by the cockroach feces, vomit or shed skin. This affects people suffering from asthma as the impure air might trigger an attack. 

How to exterminate cockroaches and prevent diseases 

The most effective way is to reduce the possibility of these pests from entering your property. 


Cleaning your spaces regularly will make it less appealing for cockroaches to breed and remove any bacteria or virus they could potentially spread. You should also clean any cooking utensils, cutlery before and after use and pay attention to work spaces, sinks and drains to ensure that they are clean at all times. Get rid of any spilled or leftover food immediately, to cut off their food source and stop them from surviving. 

Hand hygiene

Wash your hands with soap and warm water regularly to eliminate any bacteria, germs or viruses that could be spread by cockroaches. It should be done especially before and after eating, preparing food or after using the washroom. 

Seal cracks and gaps 

Sealing cracks and gaps helps to lower the number of entry points for cockroaches, which lowers the risk of transmitting diseases through your homes. It is advisable to regularly inspect and repair any damaged drains or pipes.
