Learn how to make your own homemade fly spray recipe. This is a wonderful natural fly spray that will help prevent flies around your homestead and while you work with your livestock. You can relax knowing that it’s made with natural and safe ingredients instead of unknown chemicals. 

You know how in the book of Exodus, one of the ten plagues was massive amounts of flies?

When I was younger, I always thought “Well, that one wouldn’t be THAT bad…”

I take it back.

A few years ago, we had massive amounts of flies. It was a constant battle to keep them off of my animals, out of my food, and off of my baby… (It got so bad, I even got bug nets for the playpen!)

Of course, the typical solution is to use hardcore chemicals and sprays to drive the flies away.

I just don’t feel good about doing that anymore.

Especially when I’m milking my cow.

I know from experience with my horses, whenever you apply fly spray, it gets everywhere. On your hands, on your clothes, in your mouth. I don’t want those chemicals floating anywhere near my lovely raw milk.

So I started experimenting with homemade fly spray recipes. Last year I tried a few white vinegar/dish soap/mouth wash concoctions. While they sorta worked, I wasn’t super impressed with any of them.

This homemade fly spray recipe with essential oils works much better.

More Natural Fly Control Tips for Your Homestead

I kinda feel like a pro when it comes to natural fly control these days. We deal with them. A lot. So I’ve written about my natural fly control strategies plenty of times.

Here’s some more tips for you:

Mix together in a spray bottle. Apply to the animals frequently (give it a good shake before applying). And be careful, it smells strong. Whew!

The final verdict?

It works. But if you are expecting your homemade fly spray to be like conventional fly sprays lasting for several days, you will be disappointed.

From my observations, it repels the flies, it doesn’t kill them. I had to apply 1-2x per day for maximum effectiveness, but at least it provided temporary relief without chemicals. I will definitely be using it during my milking routine and on my horses and goats, too.

Natural Fly Repellents That Actually Work

Enjoying the outdoors is a favorite pastime until a swarm of uninvited guests shows up: FLIES. Bug sprays and insect repellents such as DEET are proven and effective fly repellents, but in recent years, people have looked for natural fly repellents that actually work.

So, which natural fly repellents are scientifically proven to keep flies at bay? We’ve researched which have scientific backing versus which have mostly anecdotal support.

In this article:

How To Make Natural Fly Repellents 

DIY fly repellent spray: In a bowl, mix 1 cup of water, 1 tablespoon of vinegar, and a few drops of dish soap. Spray around the home to deter flies. You can use the following essential oils to boost the power of the spray, but always use caution with essential oils. They can cause allergic reactions and harm pets.

Most effective essential oils: Lemongrass, catnip, citronella, and cinnamon

Toxic to pets: Lemongrass, cinnamon, tea tree, and peppermint essential oils, among others, should be avoided around cats and dogs.

DIY fly killer spray: Mix ½ cup of water with ½ cup of isopropyl alcohol (found at your local drug store) and 1 teaspoon of liquid dish soap into a spray bottle (add water first so soap doesn’t bubble). Spray directly onto pesky flies to kill them.

Historical Uses of Plants as Fly Repellents

It’s unquestioned that at least some plants have insect repellent qualities. It stands to reason: Plants don’t want insects gnawing on them any more than we do. So as they evolved, plants developed natural bug repellent properties. 

Many plants release a vapor when eaten, for example. Ancient people didn’t know that, but they did know burning the leaves of some plants, such as the neem tree, would lessen the bother.

Some are more effective than others, but data is still being collected on the topic.

Natural Fly Repellent Ingredients that Work

Here’s a breakdown of some scientifically proven solutions for your spray bottle, along with a sample of common folklore solutions, supported mainly through anecdotes.

Ingredients With at Least Some Scientific Backing

Pro Tip: It’s important not to confuse “oil of lemon eucalyptus” with the similarly named “lemon eucalyptus essential oil.” 

Pro Tip: Lemongrass essential oil is toxic to pets.

Pro Tip: Growing catnip in your home or garden can help repel flies.

Pro Tip: This compound is specific to coconut fatty acids — not coconut oil itself. 

Citronella candles also are extremely popular, but “field studies against mixed populations of nuisance mosquitoes show reductions in biting around 50 percent, although they do not provide significant protection against mosquito bites,” the report said.  

Pro Tip: While citronella essential oil products can be safe to apply to the skin, they are toxic to many pets.

Pro Tip: Cinnamon and cinnamon oil can cause skin irritation and digestive problems in pets and humans.

Mostly Anecdotal Support

While all have shown some promise with keeping bugs away, it’s best to use this in combo with other methods and enjoy the scent.

Keep a Tidy Lawn to Reduce Flies

Though natural fly repellents’ day has not yet fully arrived, there’s still plenty you can do to reduce the insect’s presence in your life. One of the best ways to keep flies away is to maintain a lawn and garden that flies find unattractive. 

Here are a few ways to keep flies at bay in your lawn:

Some Natural Solutions Attract Flies

Instead of repelling flies, some repellent recipes attract them into a trap.

Sugar-Sweet Flytraps: Particularly good at catching gnats and fruit flies.

You Need:

How To:

  1. Mix ingredients together in a mason jar.
  1. Cover with plastic wrap (make certain it’s tight across the top). 
  1. Secure with a rubber band.
  1. Poke a few holes in the top and place close to fruit or wherever these pests are congregating.

Soda-bottle traps: Great for house flies and a fun DIY project to do with the kids.

You Need:

How To:

  1. Carefully draw a line with a marker and cut off the top of the bottle below where the neck tapers, usually just above the label works. 
  1. Flip the top upside down without the lid and put it into the bottom like a funnel. Note: If the top is cut too small and falls in the trap won’t work. 
  1. Bait: Water and something sweet. A 50/50 mix of sugar and water, fruit pieces, or even a few drops of fruit-scented dish soap works. 

Pro Tip: You can hang the trap by punching two holes through both layers of the trap, then thread wire into holes, crimp ends of the wire, and voila! A hanging fly trap. 

Flypaper: Modern versions are not toxic, they’re just sticky. Flypaper has dropped in popularity in recent years, probably due to having dead fly bodies suspended in living spaces. You can buy them at most grocery or hardware stores, or on Amazon. com.

Carnivorous Plants: Plants that trap flies, like the pitcher plant, will munch on the bugs and set you free.

Unregistered Repellents

Some plant-based fly deterrents (legally) fly under the regulatory radar. The Environmental Protection Agency (EPA), has listed several natural ingredients often used in these repellents as minimum-risk pesticides. Products with these active ingredients are not registered by the EPA.

Examples of ingredients used in unregistered repellents are:

Note: The EPA does not evaluate these ingredients for effectiveness, only whether they’re safe for people to use. Without science to prove how they repel flies and other insects, these natural fly repellent sprays are more a matter of personal anecdotes and folklore.

The EPA’s webpage gives more information about minimum risk pesticides if you’re interested.

The 2011 study on plant-based insect repellents in Malaria Journal notes that testing efforts to evaluate and develop safe and effective products are ongoing: 

“Recently, commercial repellent products containing plant-based ingredients have gained increasing popularity among consumers…[T]hese [products] are commonly perceived as ‘safe’ in comparison to long-established synthetic repellents although this is sometimes a misconception.”

Much more standardized testing is needed, the study said, “to better evaluate repellent compounds and develop new products that offer high repellency as well as good consumer safety.”

Are Plant-Based Products Better?

Even if a plant-based substance shows promise, that doesn’t mean it will lead to a product friendly to humans and the planet. As the study in Malaria Journal points out, “Some natural repellents are safer than others, and it cannot be assumed that nature equates to safety.”

It’s not necessarily true that extracting repellents from plants is better for the earth, either, the study says. “While plant volatiles are naturally derived, distillation requires biomass energy, extraction commonly uses organic solvents that must be disposed of carefully, [and] growing the plants uses agrichemicals, such as fertilizers and pesticides (unless sourced from a sustainable and organic source).”

Don’t Forget the Fly Swatter

While there is a case to be made for natural fly deterrents, science has yet to prove that all-natural remedies are anywhere close to being as effective as a fly swatter. Many, though not all, natural solutions are unscientific, anecdotal remedies passed down from generation to generation or, in today’s Internet age, passed along on social media. 

For the best results, stick to ingredients that have scientific backing. With a little bit of science, trial and error, and a few fly swatters, you’re sure to find a few natural fly repellents that work.

FAQ About Natural Fly Repellents That Actually Work

Is There a Natural Fly Repellent that Actually Works?

Catnip oil, oil of citronella, and oil of lemon eucalyptus (or PMD, its synthetic counterpart) are included as active ingredients in EPA-registered insect repellents. A comprehensive approach yields the best results, though. A combination of repellants, attractants, and a clean home and yard will provide the best fly control.

What Scent Repels Flies the Most?

The ingredients that best repel flies include oil of lemon eucalyptus, lemongrass, catnip, citronella, and cinnamon.  

Essential oils can be toxic for pets and cause allergic reactions in people so use them with caution. If you believe your dog has ingested or come in contact with essential oils or liquid potpourri, call your veterinarian or the Pet Poison Helpline at (800) 213-6680.

How do you Keep Flies Away Permanently?

Keep it clean. Make sure animal waste is removed and disposed of properly as this, too, can create a fly problem. Trash cans should be well-maintained and closed at all times. You should also clean out all areas that collect water, as these attract not only flies but also mosquitoes. 

When to Call a Professional

Flies multiply quickly, and even clean homes can run afoul of these filthy creatures. If the DIY solutions don’t work or you need extra help, consider calling a pest control professional to find the source of why bugs are bugging you.

How to get rid of flies: remedies, instructions

Flies in the house are not only an irritant, but also a source of potential danger to residents. RBC Real Estate explains how to kill flies indoors and prevent them from appearing in the future

Photo: Shutterstock

Flies live on average for about a month, but if they settled in a house, they manage to do a lot of harm to people during this time. These insects multiply rapidly and interfere with the tenants of the apartment. Together with an expert, we figure out why flies are dangerous, how to get rid of them using folk, industrial methods, and when it's time to resort to the help of professionals.

The material was commented by Petr Fisenko, Disinfector Specialist of the Dez_Hunter Disinfection Service

Where do flies come from

Flies enter the apartment from the street from the entrance or through ventilation openings and multiply within it. Insect larvae often enter houses with spoiled vegetables and fruits.

The problem is especially urgent in summer, when it is hot outside and insects actively breed on organic garbage. By the way, in summer, flies can do without visiting human dwellings, but once inside, they often cannot fly out of the room: due to the peculiarities of the reticulum structure of their eyes, they do not distinguish glass.

The "invasion" of flies often happens in autumn, when the temperature outside drops - they instinctively look for a warmer place. For the winter, insects hibernate and may well remain in the secluded places of the apartment to wake up in the spring.

Why flies are dangerous

In addition to annoying buzzing, flies, like most insects, also cause more serious problems - they are carriers of infectious diseases, including tuberculosis, typhoid, cholera and helminthiasis.

Insects feed through a long proboscis, preferring liquid food. Getting into the kitchen, they will first of all fly to a mug of cold tea, spilled compote or a drop of honey left on the table. Bacteria spread quickly, getting from the paws of flies to food and garbage. If an insect lays eggs in food, it can be very poisonous. In particular, for this reason, doctors advise avoiding street snacks, especially during the hot season.

Flies bite and can cause allergies, severe irritation and itching. Insect bites should be disinfected as soon as possible, for this any of the sanitizers that have become familiar in everyday life will do.

In most cases, the problem is easier to prevent than to solve. If the windows are open during the warm season, they need to install screens. Seal gaps, do not leave doors open for a long time. You can also install a couple of traps in the entrance or hang ribbons so that the flies that enter the house do not fly to the apartment. Food and drinks should not be left in the room, dirty dishes should not be left in the sink, surfaces should be wiped, and pet bowls and toilets should be clean. Organic trash attracts flies even if it's in a closed closet or bucket, so it needs to be taken out daily. Sink drains in kitchens and bathrooms must be kept clean.

How to get rid of flies: 9 products

1. Traps

Self-made fly traps should contain bait - pieces of fruit, syrups, jam. In parallel with the destruction of flies that are in the room, install screens on the windows so that new insects do not fly in, attracted by the smells from the trap. Instructions for making a trap are given below.

2. Tapes

There are many options for special insect tape. It is hung on a ceiling or a chandelier, flies sit on a trap, stick and die. You can make the tape yourself: cut the paper into strips, grease it with rosin or resin, in which castor or linseed oil, glycerin and sugar are dissolved. The mixture must be prepared in a water bath.

3. Fumigators

These are best used in closed areas where people and pets should leave for a while. Close windows and doors, plug the fumigator into a socket and wait for the required time, which is indicated in the instructions for the product. Then the room needs to be ventilated, and nets on the windows are desirable so that the insects do not fly into the treated apartment again.

4. Aerosol sprays

It is essential to use insecticidal products away from food and personal hygiene items. Make sure that pets do not enter the treated area for a couple of hours - chemical sprays can be dangerous for them. After use, ventilate the room and wipe the surfaces on which the sprayed substance has settled with a damp cloth.

5. Essential oils

Like many insects, flies are sensitive to odors. Try lighting citronella candles or an aroma lamp with lavender, basil, eucalyptus, or mint essential oils. You can also add them to water and spray doorframes and window sills with a spray bottle.

6. Plants

Some herbs have a strong, specific odor that repels flies. You can arrange in vases or spread out branches of wormwood, bird cherry, elderberry or nettle in a room with flies. Both fresh and dried plants are suitable - for some time they also spread a bright aroma around.

7. Darkness

Light attracts flies. Therefore, if you darken the room, leaving only the window open, there is a chance that the insects will fly out. But this method is relevant only if there is nothing in the room that could interest them - drinks, food, dirt and garbage. Otherwise, the flies will continue to feed and breed without trying to leave the apartment.

8. Fly Swatters and Vacuum Cleaner

An old tried and true way to kill some insects is physical impact, rolled up newspaper or commercially available fly swatters will do. Flies can be collected with a vacuum cleaner, but then the contents of the garbage bag should be thrown away immediately. But such methods are good if there are one or two insects in the apartment or the owners want to relieve nervous tension.

9. Professional disinfection

If there are too many insects, and the available methods have been tried and do not help, it makes sense to turn to exterminators. Specialists will treat the premises.

How to make a fly trap

A plastic bottle with the neck cut off is useful for this. There should be bait inside, preferably something sweet. Then the paper sheet folded into a cone is placed inside the bottle with a sharp edge, so that the tip does not touch the liquid. Flies will climb inside, but they will not be able to fly back through a narrow opening.

Another version of the trap is with soap suds. At the bottom of the jar, table vinegar and a few drops of dishwashing detergent are poured. The top of the jar is covered with cling film and a hole is made through which the flies can get inside.

Petr Fisenko, Disinfector Specialist of the Dez_Hunter Disinfection Service:

— Is it possible to use folk remedies like wormwood and essential oils if there are pets in the apartment?

- Plant repellents and some essential oils have a strong odor that irritates and disorientates insects. The phytoncides they secrete can kill flies. Insects cannot be nearby and quickly leave the room. But you need to use them with caution, pets can be allergic to these smells, so it is better to isolate them while using the products.

- Is it worth additional treatment of surfaces where there were flies?

— Flies can spread dangerous infections and diseases. That is why, first of all, you need to make sure that food does not get into the food, on which insects could leave eggs. It is necessary to regularly wipe the surfaces of dining tables with soda solution, wash fruits and vegetables thoroughly before eating, and do not leave ready meals in the public domain. Clothing and textiles of these insects attract little.

— When is the situation critical and you need to call professionals?

- If two or three flies flew into the apartment through the window - this is not a disaster, you can deal with them yourself (for example, using Velcro or aerosol) and they will not cause much harm. The situation becomes critical when, in the absence of an obvious source of flies, it becomes more and more. If you do not have dampness in your apartment, mosquito nets are installed on the windows, the garbage chamber in the entrance is in proper sanitary condition, and flies appear regularly and in large numbers - this is a reason to turn to specialists. As practice shows, fly nests in an apartment are often found in the most inaccessible places: in cracks and crevices under window sills, in ventilation, in closets. Only a disinfectant with sufficient experience will be able to determine the source of insects and competently eliminate it.

— How do professionals treat a room?

— The extermination of flies in the apartment is carried out using a cold fog generator. This is a method of spraying an insecticide with air, in the form of an aerosol, with particles no larger than 100 microns. In the process of processing, a haze or a cloud with a fine dispersion of a substance spreads throughout the room, enveloping it and penetrating into various cracks and hard-to-reach places. Processing time depends on the area of ​​​​the apartment, on average it is 30-40 minutes. After at least three hours, you can return to the apartment and ventilate it thoroughly for an hour. Subject to all the recommendations of the disinfector, the treatment does not pose any danger to people and pets.
