Find out about fly-borne diseases

Unlike other insects, such as mosquitoes, which transmit disease directly, diseases transmitted by flies are indirect, as they do not bite. The WHO reports that flies are the cause of illnesses such as diarrhea and skin and eye infections.

It has also been proven that flies can transmit pathogens from food, as well as their toxins and antibiotic resistance. Areas close to slaughterhouses are at higher risk of fly-borne diseases.

Houseflies transmit these diseases:

  • Anger
  • Conjunctivitis
  • stomach flu
  • salmonellosis
  • Tuberculosis
  • Typhoid fever
  • Dysentery
  • shigellosis

How do they transmit diseases?

Flies usually feed on rotten matter as well as animal feces. When a fly comes into contact with a food source infected by bacteria, viruses or parasites, these accumulate in its esophagus or digestive tract.

Unlike other pests, flies can only feed on liquid or semi-liquid substances because they don’t have teeth that allow them to chew or bite. When they encounter solid food, flies regurgitate a liquid made up of saliva and digestive juices, which break down food molecules to form a liquid substance, allowing them to eat it. Due to this habit, any microorganisms living in your esophagus will be transmitted to the point of consumption.

Likewise, bacteria that live in your digestive tract can infect food when you defecate in it.

Flies can also transmit pathogens through direct contact. Houseflies can become infected with pathogens in their feeding areas as well as their mating places, which is why houseflies can pick up particles with bacteria and viruses in the tiny hairs on their feet and body. When a fly lands on a product for human consumption, or any other product, any associated pathogens can easily be transmitted in their landings.

How can you get infected by flies?

The most common form of transmission is through contaminated food or drink. You can get sick from consuming any food or drink a fly has: regurgitated, defecated, urinated on, or simply landed. The transmission of the disease can also occur through contaminated cutlery or kitchen utensils.

One can get sick from direct contact or from touching an infected product and then touching our eyes, wounds or scratches.

remove breeding sites

Common fly breeding sites such as garbage cans, dead animal remains, and droppings are a major source of fly-borne illnesses. By eliminating and treating these areas, we will reduce the risk of contaminating flies with microorganisms and at the same time reduce the fly population.


Proper waste management should be carried out to ensure that containers do not overflow and are emptied regularly. Dumpsters should be securely closed at all times and these units should be cleaned regularly.


Bathrooms should be cleaned regularly and plumbing should be flowing freely to avoid problems. Screens must be used on all openings and drains to prevent flies from entering our facility.
