Barn Fly Remedies

Last Modified on Jul 26, 2014

Do you have a barn fly problem? Or are flies of any kind troubling your pets? There are natural steps you can take to persuade flies to find their meals elsewhere, without filling your animal's environment with harsh pesticides.

Simple steps can be taken around the barn, the dog house, or wherever your animals happen to be afflicted with flying pests. Sometimes, a small change or addition to your animal's diet can dissuade flies from pestering your animals. Certain essential oils or aromatic foods such as garlic or cayenne can be natural pest deterrents, whether eaten or applied topically (usually, in a dilution--be careful with applications directly on your animal's skin or fur).

Natural Remedies: Apple cider vinegar (ACV) is so far the most popular home remedy to shoo away barn flies, and it has a long tradition of such use. ACV can be used in a sprayer or can be added to your animals' water or feed. If spraying directly on your pet or animals, dilute 1:1 with water.

[YEA]  I have been putting a cup of ACV in my horses water barrel since last spring. I noticed my gelding was drinking alot more water with ACV. A few weeks of ACV, my gelding peed out a calcium deposits the size of a walnut. It also helped with the biting flies. One of our mares would get terrible fly bites, but this year she was scab free.

I don't know the ratio of ACV to water but I do remember reading that you start off with less and then gradually add more to get the horse used to it.

ACV also makes their coats/feathers shine. I put a few capfuls in my chooks water (5 gal container) and it does help keep the flies away from the chicken poop.

Forgot to mention I sprinkle Food Grade Diatomacious Earth in their coop and run also and that also helps besides keep insects/flies away. When I clean out the coop I always use full strength ACV and let it air dry before putting down new bedding.

[YEA]  I have a Chow German Shepard mix & a Lab both are outside dogs. In the summer months we had a problem with the biting flies, which causes bad sores on my dogs. I used (ACV/Water)1 cup of apple cidar vinear to 2 cups water sprayed my dogs every other day and it helped a lot. Don't spray on open wounds.

I also have 2 small dogs and a cat inside the home that have fleas I use 70-90% full strength rubbing alcohol put it in a spray bottle and spray the animals and their bedding (do not spray eyes, inside ears or genital areas) Spray the carpets and all cracks and crevices of floors (carpets and tile) not good on wood. Not good around birds, I saturate one room, close the door and then go to next room. Put birds in a room that isn't being treated. Do not stay in the sprayed rooms leave until carpet/floor dries. Once I had a flea my arm and ankle i spritz the area with the alcohol and the flea died instantly.

[YEA]  acv pinesole worked really good for the flies my poor dogs were infested with them and when we sprayed it all over the back yard they were all gone.

[YEA]  I mix ACV with Avon Skin So Soft, Citronella and water to make a fly spray for my horses and mini donkeys. Have also tried it on my dogs and it smells great.

does this not sting or hurt their bites??? and is it safe, don't get into blood stream? I was considering SSS from Avon and have tried tea tree oil mixed with mild detergent/shampoo.

[YEA]  I was absoluetly amazed with the resuts after I started using ACV, pine sol and water as a spray on my horse,I also sprayed it in her stable and the flies are gone, You will still see a few but not near as many as there was,I mixed equal portions of ACV,skin so soft and waterand rubbed on her face careful not to get it in her eyes,she tilerated it ok not as good as sher normally is,but would you like the smell,the next day you can't hardly smell it at all.Her caot is so shinny and soft.I think I have discovered something, No more expensive fly spray.

[YEA]  I have been using ACV on JR this past year and have seen a big difference in using this product then any of those commerical fly sprays. I give him around 1/2 cup per day with 2.5 lbs of grain. I also mix in corn oil around 1/2 cup and this has kept his coat looking shinny and flys to a minmum. Great Stuff!

[YEA]  I have a beautiful, 6yr old standard bred mare that i only bought about 6 weeks ago, who was very impressive looking when i first laid eyes on her, she was very healthy and strong, she stands 15.2 and now she has been under attack by flies and mosquitoes and you can just see her aggravation --she runs herself into a sweat and has even lost weight from it , she's not as pretty because she has tons of bumps all over her body. So i took it upon myself to look on the internet for a solution and found this site. I have now been using the acv and canola oil and have mixed it 60/40, more acv then oil. I think it's working so far because she is healing and seems happier. I'm now thinking of using it in her feed to see what results i get from there. thanks for this site, I'm confident this will be the best thing for her in the end.

[YEA]  Yea, ACV. We have a 15 yr old mare that was getting bitten by flies and bleeding from them. We used ACV and Garlic in her food daily and could really see the difference in her bites. When we had gone on vacation the care givers ran out of ACV and when we returned we saw more bite marks on her again. The ACV and garlic both really work. It also keeps the flies down in the corral and barn.

Apple Cider Vinegar and Garlic? My horse is being driven crazy and so am I by his state! What mixtures do you use/quantities? My Gypsy Horse wont eat garlic although I put fresh garlic in all his feed bins he just leaves them behind. How do you get the garlic in the ACV? Is it fresh, granules or powder? I'm desperate for these answers. many thanks. Charles

Posted by Wishapup (Southeastern Area, Ontario, Canada) on 05/13/2013

My dog is plagued by flies every year (especially her sensitive, floppy ears) and the only thing that's worked well so far is a strong chemical product that I apply to her ears and do not like using.

Last year, I compounded a homemade mixture, but I don't think it was quite strong enough. It deterred some of the flies but she suffered nonetheless.

This year, I want to try a mixture of:

2 cups water
2 cups Apple Cider Vinegar
1 tbsp lemon juice
1 tbsp Cayenne pepper
1 packet Avon Skin-So-Soft
10 drops spearmint oil
10 drops citronella oil

I plan to mix it in a spray bottle and mist it on her coat. Does this sound okay? Strong enough? Right proportions?

I'm determined to keep the flies off this time.

[YEA]  You mix 15-20 drops of spearmint oil in a spray bottle with water, spray on fur and ears, careful not to get in eyes, you can spray dog houses, the outer perimeter of your home and the flies disappear almost instantly. my dogs are 7 and I have never found anything that worked until I tried this.

Posted by Dawn (North Hollywood, CA) on 07/10/2006

[YEA]  I would like to tell you about something I discovered I did not see on your site. Dogs and Flies... My dogs were being eaten up by flies, a friend recommended spearmint oil and it worked. I have been using it over a week now and there has not been one fly around them since. IT WORKS.

[YEA]   We moved homes and have a nice back yard now w/ shade. Our 2 lab mixes just started getting pestered by tiny flies all of a sudden (May-June-through now July). We wash them every week. They are indoor/outdoor dogs. Went to Whole foods to buy some essential spearmint oil to mix w/ h2o. Just sprayed our dogs... So far its working.. Hope it continues!! Thx for the easy and wholistic tip!

Dear People who post to this site: Please be specific when you post your remedies. example pet category: Flies: One post says 10-12 drops of spearment oil in a spray bottle.

This is not specific enough to be helpful. 10-12 drops in a 2 oz, 4 oz, 8 oz, 10 oz or 20 oz spray bottle... With water? with oil? with ???? I love that people share what has worked for them but I have a request for them that they be specific enough that we can repeat their success!! Do not post remedies that are not complete enough for them to be helpful or useable. TELL US WHAT YOU DID!! Thank you! Lace_ lael

Tea Tree Oil   1  0

[YEA]  Hi!

A farmer my son knew had a sick calf that he didn't have time to deal with and gave it to my son, hoping he could nurse it back to health and then keep it. So this calf had some kind of parasite/bugs on the face. I mixed up tea tree essential oil and water (1 T. oil to 1.5 cups water) in a spray bottle. My son sprayed this on the calf in the face a couple of times a day. It did seem to rid her of the parasite. We also noticed that flies were no longer on her face. If we sprayed her whole body she would be fly free for hours. I guess this would be an expensive long term solution (and not very convenient)but for a sick animal who needs to be spared the further irritation of flies, it works.

By the way, my son has had the calf for 6 weeks or so by now. She is doing well. I think she is going to make it! She is very sweet and friendly and hangs out with our big cows.

Vaseline and Cayenne Pepper   3  0   

Posted by Diana (Florissant) on 08/05/2006

[YEA]  I did not try any remedies from your website as I just ran into the website today. I do have a remedy, if you wish to post it, if it is already not on the website. When I took my German Shepherd to the vet for his shots. She noticed that the tips of his ears were oozing and told me that flies like to bite the tips of German Shepherd ears and it leaves them crusty from the dried oozing. She did not have a product in stock to prevent the flies from biting, but suggested that I put a bit of vaseline on the tips of his ears to soften the crusts. And I said I would and also would put some red pepper (cayenne) mixed in it so that the flies would leave them alone, which did the trick. I had never noticed this before on his ears; only this year. He is nine. So I hope I didn't miss it all these years. We just moved and this is the first summer in this new location.

[YEA]   The cayenne pepper and vaseline remedy worked wonderfully in reference to keeping the biting flies off our dog's ears! We have a two and a half-year-old at home who loves to play with the dogs, and has excluded us from using the commercial sprays and ointments that contain pesticides.

We had mixed 1/2 tsp. of cayenne pepper to 1 tsp. of vaseline, and the dogs seemed to tolerate it very well. Before our son came along, we used Fly's off, which worked well, but the dogs hated it. The minute we applied it the dogs would go into a frenzy trying to get it off their ears.

We will also try the ACV and water in the future.

A hearty THANK-YOU to all who have shared the information!

Hey Cheryl!

I can see no reason why this would not work for your mule - please give it a try and report back!

1/2 cup of cayenne pepper to 1 cup of Vaseline - you can double this if its not enough.

Good luck!
