How To Kill Germs, Bacteria And Viruses In The House Or While Travelling

Learn how to use natural disinfectants like UV light, vinegar and alcohol to kill germs like bacteria and viruses the way medical professionals do.

Every few years, humankind comes across a pathogen that has the potential to wipe out millions of people. From the plague to the Spanish flu, Ebola, H1N1, SARS, MERS and now COVID-19 (short for coronavirus disease).

The primary concern that everyone on Earth now faces is how to avoid getting infected with the new COVID-19 coronavirus. In this article, you’ll learn how to kill germs on hands and in the home, and how to kill flu germs on surfaces.

Watch this video by the CDC to learn how the COVID-19 coronavirus spreads.

3 Common Sense Tips To Avoid Catching Germs

In an uncertain and ever-changing world, there are a lot of things that are beyond your control, so it’s better to concern yourself with the things you can control, such as how to avoid germs like bacteria and viruses.

Here are some common sense ways to avoid catching germs:

1. Wear a reusable, washable face mask for germs

Many airborne pathogens are spread through droplets released by sneezing or coughing. Don’t bet your life on other people caring enough to cover their mouths or noses.

Instead, wear a protective face mask or scarf to avoid inhaling germ-carrying droplets. According to this article in The Guardian, masks are effective at capturing droplets, which is a main transmission route of coronavirus.

If you’re likely to be in close contact with someone infected, a mask cuts the chance of the disease being passed on. If you’re showing symptoms or have tested positive for the virus, wearing a mask can also protect others.

Unlike the terraformers in the Alien Covenant movie, who tried to explore an alien planet without wearing protective suits (What were they thinking?) resulting in horrific consequences, you can use common sense and wear some protective layers to avoid catching germs.

You don’t have to wear an Antiviral Hazmat Suit and Bionic Face Shield every time you go out. A winter scarf or neck tubes can provide enough protection to ensure you don’t get exposed to any great extent to airborne pathogens.


Simply covering your face with a winter scarf, washable face mask or even a ski mask can prevent you from inhaling germy droplets and germ-carrying dust particles in the air. It will also prevent you from touching your face throughout the day.


Here are some tips to tie a scarf properly.

When you return home, soak the scarf or face mask in 20% vinegar and wash it in soapy hot water before drying it. Keep a number of scarves or face masks handy so that you have enough for everyday use.

2. Wash your hands frequently with regular soap & water

While most people are making a beeline for the hand sanitizer, they don’t realize that frequent handwashing with regular soap is the best way to prevent the spread of germs.

But does alcohol kill germs? Does rubbing alcohol kill bacteria on the skin, and does alcohol kill flu viruses? Yes, in fact, the CDC advises using a hand sanitizer with at least 60% alcohol if you cannot wash your hands, as it can quickly reduce the number of microbes on hands in some situations.


Alcohol can kill viruses, including influenza and coronaviruses, by breaking down the lipid membrane surrounding the virus and inactivating it. However, viruses that lack this envelope, such as norovirus, may not be inactivated by alcohol.

Unfortunately, hand sanitizers don’t eliminate all types of germs, so don’t depend on them too much. Natural hand sanitizers made with ingredients such as essential oils and aloe, while good for your skin, cannot guarantee that they kill all germs and viruses.

Hand sanitizer dangers include alcohol poisoning from swallowing alcohol-based hand sanitizers, so don’t use hand sanitizer for kids as they’re likely to put their hands in their mouths. Also, avoid products that contain triclosan.

Instead, help your child understand the importance of covering their mouths and handwashing to help prevent the spread of germs and viruses with the children’s book, Germs Are Not for Sharing.


3. Disinfect frequently-touched surfaces daily

According to this article in the BBC, viruses like Covid-19 can be spread in tiny droplets released from the nose and mouth of an infected person as they cough.

Some studies on other coronaviruses, including SARS and MERS, found they can survive on metal, glass and plastic for as long as 9 days unless they are properly disinfected. Some can even hang around for up to 28 days in low temperatures.

According to the CDC, disinfecting frequently-touched surfaces daily is key in preventing Covid-19’s spread.

How To Kill Bacteria And Viruses In The House

Want to know what kills viruses, how to kill flu viruses, and how to kill coronavirus on surfaces? There are many natural and eco-friendly ways to kill germs and viruses in the home by making use of natural disinfectants.

If you want to learn what kills germs and bacteria, what kills the flu virus, and how to kill the flu virus in houses, read on.

Use UV Light To Kill Germs

Does ultraviolet (UV) light kill germs? Yes, far-UVC germ-killing light kills 99.9% of germs and bacteria, including dangerous viruses like MRSA, H1N1 and Ebola, as well as drug-resistant bacteria within just a few seconds.

How does UV light kill germs? On the UV light spectrum, there are UV-A, B, and C lights, but UV-C is the light that kills germs.

Ultraviolet germicidal irradiation (UVGI) is a disinfection method that uses short-wavelength ultraviolet (UV-C) light to kill or inactivate microorganisms by destroying nucleic acids and disrupting their DNA, leaving them unable to perform vital cellular functions.

UVGI is already used in a variety of applications, such as food, air, and water purification. In fact, the medical and scientific community already know how to get rid of germs in the air with UV light and regularly use UV light to sterilize hospital rooms and labs.

does uv light kill germs

In hospitals, UV-light-emitting robots zap operating rooms of all pathogens, and Boeing designed a prototype for a self-cleaning aeroplane bathroom that uses UV light to disinfect after each use.

Scientific studies such as the paper, Far-UVC Light: A new tool to control the spread of airborne-mediated microbial diseases, have shown that far-UVC light efficiently inactivates flu viruses with about the same efficiency as conventional germicidal UV light and can be a very efficient virus killer.

According to the review article, Can UV Light Fight the Spread of Influenza? far-UVC light may offer a low-cost solution to eradicating airborne viruses in indoor public spaces.

Far-UVC light has a very limited range and cannot penetrate through the outer dead-cell layer of human skin or the tear layer in the eye, so it’s not a human health hazard. But because viruses and bacteria are much smaller than human cells, far-UVC light can reach their DNA and kill them.

So if you want to know how to kill germs in the air, Far-UVC lights are the best natural germ killer as they are relatively inexpensive and are likely to be effective against all airborne microbes, even newly emerging strains.

This UV germ killer light can kill germs on practically any surface, even on porous surfaces. Today, you can buy a number of portable UV sanitizing devices that claim to kill 99.9 per cent of bacteria and viruses. Here are some of them:

Use Vinegar Instead Of Bleach

Does vinegar kill germs? The answer is yes! Vinegar can kill germs such as bacteria, viruses and yeast. Research has shown it can be effective against some bacteria and viruses, including the flu. However, it does not kill dangerous bacteria like staphylococcus.

Vinegar is also biodegradable and can also be used as a safer alternative to bleach for some applications, such as cleaning. Concentrated (20-30%) vinegar has been widely used to replace many harmful and expensive commercial cleaning products.


You can use vinegar to kill flu germs on fabric, so if you want a homemade counter cleaner that kills germs, 20% industrial strength white vinegar is the perfect natural disinfectant for cleaning and laundry.

Use Isopropyl Alcohol On Surfaces

Does rubbing alcohol kill germs? Yes, rubbing alcohol naturally kills bacteria and viruses, but experts don’t recommend using it to disinfect your home.

Although the CDC advises using an alcohol solution with at least 70% alcohol for disinfecting surfaces, the alcohol evaporates too quickly, and items really need to be submerged in isopropyl alcohol for 10 minutes to do its thing.


Also remember, that alcohol is highly flammable and storing a lot of it or using it too liberally can create a fire hazard.
