House flies are vectors for disease

There are more than 150 different kinds of illnesses that can be spread by house flies. They can carry bacteria, viruses, and parasites on their bodies, legs, and wings. Some types of these organisms live in the flies’ digestive systems and others can be rubbed off onto whatever they land on.

They can transmit bacteria and viruses

House flies can be a nuisance, but they also pose health risks. Their saliva and faeces can contaminate food and drink, which in turn could lead to food poisoning. They are also carriers of the bacteria salmonella, which can cause gastrointestinal illness. It is said that they were used as biological weapons by the Russians during World War II because of their ability to transmit disease-causing bacteria.

As a result of their ability to carry disease-causing bacteria, it is recommended that you clean up areas where they gather or breed and not to touch them at all. If you must, make sure you use gloves because they can cause infections.

You should also avoid handling any of your animals’ food or water, as flies can contaminate them and cause health problems. To further reduce your risk of getting ill from house flies, wipe down work surfaces regularly and do not leave raw meat out for long periods of time.

They can also cause food poisoning

House flies can carry many diseases and parasites. They can also cause food poisoning. For example, a house fly can pick up E. coli from cow manure, then fly over the hamburger you are grilling for dinner, and contaminate your food with E. coli when they land on it.
In addition, they have been known to spread salmonella and tuberculosis bacteria as well as other dangerous microbes that can make humans sick.

There are many ways flies get into your home and contaminate food. They can enter from doors, windows, under sink cupboards, near garbage cans or by simply walking through open doors or windows.

How to get rid of them if they are already in your home

House flies can be a nuisance, but they are not harmful to humans. To get rid of them in your home, you’ll need a flyswatter or a rolled-up newspaper. You can also try opening windows and doors so they can find their way out. For an easy, chemical-free solution that doesn’t involve killing the flies, try placing bowls of water with fruit peelings in them around your home.

If you have a large population of house flies that have gotten inside, you can spray them with soapy water using a spray bottle. This can also be effective if done outside around your home. If you notice an area where flies seem to congregate, it is possible to install traps made specifically for these types of insects in that area. You can also try adding sticky strips around your home’s entry points and exits as a way of deterring them from entering and exiting your home.
