There are at least more than 150,000 species of flies found in the world, while houseflies probably belong to the common group of fly species that are widely widespread and infest a home and business.
More than just annoying and irritating insects which you commonly witness landing on your favourite foods and kitchen utensils at home; houseflies can act as indicators of the dangerous bacteria present in the business environment.
From a business perspective, it is believed that diseases carried by houseflies will have a negative impact on both customer and staff health, resulting in damages to income, brand reputation, and staff retention.
Let’s find out the reasons why house flies are such dangerous pests than we ever thought.
On top of being the most common fly pest around the home and business property, houseflies (Musca domestica) are also noticeable for spreading bacterial diseases and infections to humans just as terrible as rats and cockroaches do!
According to the World Health Organization (WHO), houseflies are capable of transmitting at least 65 diseases to humans, including diarrhoeal diseases and skin and eye infections.
Houseflies are known to carry serious and life-threatening diseases, including:
A study also proved that house flies can transmit foodborne pathogens and their associated toxin and resistance. Areas in close proximity to animal production sites are at higher risk of accumulating foodborne diseases from flies.
Unlike the other flying insects such as mosquitoes that are transmitting disease through direct contact to your body, houseflies are not categorized as biting insects and are indirect rather than direct vectors of diseases.
Houseflies can transmit or spread the disease to humans in 2 ways, including:
Houseflies often feed on rotting and decaying organic matter, including human and animal faces. When a housefly feasts on a food source infected with bacteria, viruses, or parasites they accumulate the pathogens within their esophagus or digestive system.
Unlike other pests, houseflies don't have mouths and teeth or even stingers to bite and chew solid foods. However, they have a long tongue or called a proboscis to feed on liquid or semi-liquid substances.
When it comes to solid food they will regurgitate a liquid consisting of saliva and digestive juices which breaks down the food into a liquid substance, allowing them to feast. Due to this feeding habit, any microorganism living in their oesophagus will be transmitted to the item they are consuming. Similarly, any bacteria living within their digestive system can infect items they defecate on.

Houseflies are rarely breeding inside a building structure and prefer to breed in dirty places that are not being conserved. Some of the breeding grounds for house flies, including:
In referring to their filthy breeding, houseflies can also transmit pathogens by physical means. Areas where they feed, the food items themselves, as well as their preferred breeding sites, can be infected with pathogens.
Because of this houseflies can pick up particles containing bacteria and viruses on the tiny hairs on their legs and body. When a fly lands on a human food product or any other item, any pathogen which is in the attached particles can easily be transmitted to where it lands.
The most common form of disease transmission by housefly:
Preventing flies from becoming a problem can be done by taking some proactive measures to reduce the presence of flies in and around your home or business, including:
Following correct food hygiene practices can help prevent the spread of housefly diseases. This can be done by ensuring:
Eliminating the common housefly breeding sites will reduce these filthy pests to picking up disease-causing microorganisms and also help reduce the flies themselves.
