How to properly make and use yarrow as a broad spectrum insect repelling herbal tincture which has a reputation for being stronger than DEET.
My family recently spent the day at the Blizzard Beach waterpark at Disney World. Although we had a great time (I highly recommend Blizzard Beach over Typhoon Lagoon, by the way), the shady spot we chose to leave our towels and cooler seemed to be attractive for a few horseflies as well. I really wished I’d brought along a small spray bottle of yarrow as my Plan B.
The annoying appearance of these horseflies was surprising to me as Disney World is nothing short of incredible at keeping insects of all kinds away from areas where guests congregate. We’ve never had to use any sort of insect repellent anywhere on the enormous Disney World property in all the years we’ve visited, even for nighttime activities at the woodsy campground.
My husband and I have speculated for a long time on how this is accomplished so effectively because Florida is definitely in the running for insect capital of the world. Given that Disney World was basically constructed on a swamp, this makes the feat even more impressive. No doubt a chemical cocktail of immense proportions is used, but it isn’t near where the people hang out, as I’ve never even smelled the residue of spraying, and I have a pretty good nose for those sorts of things.
For whatever reason, however, this one spot where we were at Blizzard Beach seemed to elude the Disney World bug eradication police. Horsefly bites are extremely painful in my experience, and if you wish to avoid the very effective, but highly neurotoxic effects of insect repellents made with DEET to keep them at bay, I highly recommend an easy homemade tincture of yarrow.
Yarrow Herb
Note that crushing yarrow leaves and stems and rubbing them on yourself does not really work very well (neither does citronella, by the way). The yarrow potency needs to be concentrated via tincture.
Herbalist extraordinaire Susun Weed of the Wise Woman Herbal series of books says that the United States Army studied yarrow and found a tincture of this herb outperforms DEET in repelling ticks and mosquitoes.
One thing is for sure: avoiding the use of DEET containing insect repellents on yourself and your children no matter what is a wise parenting decision.
This stuff is so highly toxic – possibly worse than even spraying neighborhoods for mosquitoes. It isn’t worth it to ever use it in my opinion.
It has been known to cause seizures in young children even at low potency. In addition, a review of the scientific literature turns up 17 cases of DEET-induced toxic encephalopathy in children (1).
How Often Yarrow Should be Used to Repel Insects
The one drawback is that yarrow tincture does not remain effective as long as DEET. So, it needs to be reapplied often. I was unable to find a source for this study, so you will have to try it and see if you agree.
Ms. Weed suggests spraying yourself with yarrow tincture every 20-30 minutes if the insects are heavy. If not, every couple of hours should be sufficient. Yarrow works for repelling horseflies and other insects that are bothering your horse when you are riding too.
How to Make Yarrow Tincture
The best tinctures are made with freshly picked plants. Buying a commercially prepared tincture from the store made with dried plants is not as potent.
Fortunately, finding fresh yarrow (Achillea millefolium) is not that hard as it is a common plant that grows wild all around the world in temperate regions. It has lovely, long-lasting flowers that may be white, yellow, red, or pink. Susun Weed suggests the white or pink yarrow varieties as the best ones to tincture. She recommends picking the flowers, flower buds, seeds, stalk, and leaves from the top third of the plant.
Preparing the yarrow tincture is performed as follows:
- Discard any damaged yarrow plant material
- Do not wash any of the yarrow with the exception of the roots and only with water and if necessary.
- Coarsely chop the yarrow plant parts except for the flower and buds.
- Fill a jar to the top with the chopped yarrow. You don’t leave an inch like when you are fermenting food and drinks.
- Pour in 100 proof vodka or vinegar. I would suggest vodka as a better choice because a tincture made with a vinegar base will make you pretty smelly if you spray yourself with it. Also, use potato vodka if there is a gluten sensitivity in your home.
- Cap the jar.
- Label the jar with the date and type of plant used (yarrow).
- The next day, top up the liquid as the level will go down slightly as the plant material absorbs the liquid.
- Leave for a minimum of 6 weeks.
- Strain the tincture into a spray bottle and it is ready to use.
How to Use Dried Yarrow for a Tincture
If you absolutely cannot source fresh yarrow to make this insect repellent tincture, you can use dried yarrow. Just know that it will not be as potent and you will most likely have to respray yourself more often to achieve satisfactory results.
Note that powdered yarrow is not suitable for tincturing. You can only use the dried yarrow root, as the dried flowers, buds, stems, and leaves will not retain enough potency after drying.
Place two ounces of the dried yarrow root in a pint jar. Add 10 ounces of 100 proof vodka.
Cap and label as described above.
Top up with more vodka over the next week as necessary.
Leave for 6 weeks and then strain it for use.
Note that a properly made yarrow tincture is appropriate as a broad-spectrum insect repellent, but especially for mosquitoes, ticks, horse flies, and deer flies.

Just wondering…..could the alcohol in the Vodka be too strong for some people’s skin? If it is like regular rubbing alcohol, I don’t think it would bother me.
I don’t think it would bother you at all … the alcohol would dry off very fast like with alcohol based hand sanitizers.
This is great information!
One question: So no flowers or buds to go into the jar, just plant and root?
Thanks.
Flowers, buds, stems and leaves all go in the jar coarsely chopped (top third of the plant). They just can’t be used if dried … only fresh.
The article “recommends picking the flowers, flower buds, seeds, stalk, and leaves from the top third of the plant”, but then goes on to say in the instructions, “Do not wash any of the yarrow with the exception of the roots and only with water and if necessary.” So why wash the roots if they’re not even supposed to be picked as part of the recipe?
Also it says, “Coarsely chop the yarrow plant parts except the flower and buds”, but just above this comment you say, “Flowers, buds, stems and leaves all go in the jar coarsely chopped (top third of the plant).” So, which is it?
If you notice in the instructions, the roots are used ONLY if dried yarrow is being used.
Can you use dried herb and is it as effective?
Thanks for the recipe!
No… dried herb is not as effective and powdered yarrow won’t work at all. This is discussed above in the article if you need specifics.
Unrefined virgin coconut oil with a few drops of lavender oil does the trick on the nasty mosquitos we have in the FL summer. Apply on skin and they won’t sting through.
Thank you for sharing your knowledge.
Do you know how long the yarrow tincture will last? Thank you.
Is there any fragrance from yarrow? I don’t ever remember one, but I was wondering as I don’t do well with even natural oil fragrances. If there is some, maybe the root powder recipe might be more neutral? Thank you. Sounds like a great alternative to toxic repellants. 🙂
Yes there is a fragrance. But, it is not unpleasant at least to me. Feel free once the tincture is prepared properly to add a drop or two of essential oils to add the fragrance you desire. I prefer as is. I don’t know if adding additional essential oils will affect potency, however. I don’t think it would.
Lavender would be good to add, as it too repels insects, and adds a refreshing fragrance.
Once the tincture is complete, how long is it potent for?
Many, many months. You will likely use it up long before it’s no longer good. You will know it’s lost its potency though, when it no longer keeps the bugs away 🙂
Actually, tinctures retain their potency for years.
I know Susan Weed says that white or pink are more potent, but I only have yellow yarrow in my yard, and they haven’t flowered yet. Being in Colorado, we aren’t horribly buggy, but it would be great to have something around. Do you think the yellow would be effective as well?
Yes, it would still work. If that’s all you have fresh, then definitely make it.
People!!! Please read the article, wow all the questions you are posting for poor Sarah when she has already explained all of them in the article. Try reading first and reading also all comments to see if somebody else had the same question answered by Sarah. Sarah you have too much patience!!! Bless you.
Wow, I will be trying this! Now, not trying to be neg, Sarah, but I have done some research on Disney, and they are not the “good” guys they portend to be…everyone has to make their own decision, but it is good to let people know to do some research. Thanks for the good info!
I know Disney isn’t what it seems, but we love going there. We go several times a year (to different parks or just to hang out in Downtown Disney and shop/see a show etc) and have a great time every single time.
