Getting Rid of Goat Head Weeds, Seeds, and Stickers


If you live in an area with goat head weeds, sometimes called puncture vines or sand burrs, you're part of a growing list of people who ask: How do I get rid of them?

They are like flypaper stuck to your hands, and killing them seems impossible! My friends, you can control and kill goat head weed and keep it from taking over your yard, but it takes patience, perseverance, and some good tools.

Rapidly it begins to spread, sending out tentacles and then it will start producing little yellow or purple flowers. The roots grow deep very quickly and also spread underground, and from those roots more evil plants grow, reproducing at an alarming rate!

After they produce their little flowers, the thorns begin to grow, nestled under the leaves and vines, all but invisible until the unwary come near it. And then, it strikes! Moisture will cause it to either hug the ground (less moisture) or grow more upright, with more spreading vines (more moisture).

At the end of the season, or when the plants mature, the Goat Head thorns begin to fall off, and those are the next seasons army that you have to kill. If you have a patch that you are trying to eradicate, use a small broom to sweep them up so you can dispose of them in the trash!

If you see them sprouting, begin your treatment now. Once the night temperatures rise, they will propagate very quickly and your control efforts will be that much more difficult.

What You'll Need

  • Propane weed-burning torch (for large infestations)
  • Protective gloves
  • Chemical weed killer containing Oryzalin
  • Chemical weed pre-emergent containing Glyphosate
  • Good upright weeder/extractor
  • Tarps to lay down after you spray
  • Weed collection bin
  • Rake
  • Optional: Mulch to lay over treated and weeded area.

A Year-Round Guide to Removing Goat Head Weed

Early Winter
Early Spring
Fall and Winter
Lay down pre-emergent like Surflan as a preventative. Avoid plants you want to keep.
At first sign of Goat Head, spray with weed killer with pre-emergent chemical Surflan.
Use propane vapor torch to remove weeds. Be sure to have watering hose ready and do not work on a windy day.
For large infestations, sweep with weed burner, staying close to the ground. Try to burn roots and follow with weed killer.
Place tarp over infested areas to block sun. When plants are yellow/brown, remove tarp.
Remove plants and roots with upright weeder.
Rake area and place weeds in bin. Sweep to remove thorns.
Plant wildflowers or other ground cover
  • In the early winter or spring, lay down a pre-emergent like Surflan as a preventative. Don't use anything else that does not contain this ingredient. You'll be wasting your money. Avoid spraying any "good" ground covers, as you want them to flourish and take space away from the Evil One. If you have large infestations, sweep with your weed burner, staying close to the ground to burn out as much of the roots as you can. Follow your burn with a weed killer that will get to the roots still living underground.
  • At the first sign of their little green bodies, spray with weed killer. Tip: Spray blocks of infested and cover with a sun blocking tarp for about a week. I start closest to my house, and move outward. Peek under the tarp, and when the plants have turned yellow/brown, remove the tarp and move on to the next step.

Note: You can spray these at any time of the year, but beginning the following year, start on schedule to fully get them out of your yard.

  • Remove the Goat Head plants, including the roots, with your upright weeder. If you are limber enough, and don't have many plants to remove, you can pull them out by hand, but make sure you have protective gloves on. Also, grasp the entire plant as close to the ground as possible and slowly pull sideways to get the entire root system out. Pulling straight up usually snaps the plant off, leaving the roots still underground.
  • Rake the area, removing all goat head debris, and put it into the trash. Finally, sweep the area you cleared to pick up any goat head thorns. Remember to always put goat head weeds and thorns in your trash or burn them. They reseed like crazy, if you don't. *Note: If you are using a weed burner, you won't need to rake.
  • If you have not used chemicals, plant wildflowers and cultivate any ground covers you can to choke the Goat Head plants out.
  • Sit back, and have a cool one!

Using a Vapor Torch

With the moist fall and winter season upon us, now is the perfect time for those of you with large patches of goat head weeds to take the direct approach to getting rid of existing goat head plants.

I have had so many readers rave about using the Red Dragon VT 2-23 C Propane Vapor Torch in their yards to kill the Goat Head weeds. It saves using chemicals and the all the physical work involved in the traditional (but still good) methods.

  • Pros: The burner destroys both plant and its seeds immediately.
  • Cons: It won't always kill the roots so they might come back again.

So, for those of you with large areas to clear who and don't mind burning areas down to the soil, this is a very good option. I would recommend following with a weed root killer that I have listed in this article.

Safety tips:

  • First, you must check with your local fire department or city for regulations on its use. Some will require a burn permit.
  • Always have a watering hose ready.
  • Pre-water the boundary areas to prevent the burning from getting away from you.
  • Never burn in windy conditions!

Follow those precautions and you should be fine.

Using Chemicals

They're harsh, but necessary. In your battle with Goat Head weed, you must have chemicals ready to be deployed in your arsenal. I know it seems harsh and perhaps not always friendly to the environment, but used properly and chosen carefully they are very helpful weapons in fighting this scourge. They won't do it all, but combined with the other battle tactics I am giving you, they will thin their ranks and help you win the war.

These are the chemicals I have found to be effective when used as directed and in conjunction with the other tactics. Make sure your pets are not walking on them when still wet. I cover the areas I have sprayed with a cheap tarp until dry and this helps the product be more effective. It deprives them of sun, allows the chemical to penetrate fully, and protects my cats from coming into contact with the chemical.

Will it kill every one you spray? No, nothing does, but it will kill a lot of them. After they are dead, rake the plants and then sweep up any thorn heads.

  • Oryzalin and trifluralin Pre-emergents to be applied in late winter/early spring
  • Glyphosate and dicamba Post-emergents to growing plants.

Caution! Read all labels as some of these can kill other plants you do not want to be harmed!

My Battle Against the Goat Head Weed

I moved to beautiful Northern Arizona about 22 years ago, and loved it immediately.

Having spent years in the southern desert, the move was a welcome relief from the extreme heat and vigalence against harmful natural creatures there.

Little did I know that I was just a short time away from a struggle against the worst enemy nature could throw against humanity! The Goat Head weed. Oh, it goes by many names; the puncture vine, the sand burr, and of course it's botanical name, Tribulus terrestris. To me, it is Thy Enemy and I am at war with it!

When I moved into this house with its large, fenced yard, I thought I would be in bliss, able to create gardens full of happy plants. As a retired professional plant grower, I couldn't wait to create my own picturesque gardenscape. Then, I had my first encounter with a goat head plant.

I reached down to pull a weed from an area I was clearing, and felt what I was afraid was a dangerous sting by a bug unknown. Instead I saw a roundish, odd hard thing stuck in my skin. I went to pull it out, and was immediately impailed again on my other finger. I had not seen that there were several barbs on it.

After I got it out, I looked around and to my horror, saw that this plant was EVERYWHERE in my yard, and spreading rapidly!

I tried spraying the plants with my regular weed killer but that didn't work. I spent the rest of the summer pulling them out of my front yard, one by one, by the roots. My back nearly broke, but I had cleared away a good area and was sure they would not return.

Sadly, I was mistaken. We had a monsoon in August so severe that the yard behind ours flooded and overran the small berm separating our properties. The result was that my yard was immersed in water for several days, and it deposited millions of goat head seeds on the land around my house.

The next spring as these plants all began emerging from germination I knew I had to refine my tactics, hone my skills and now, after several more seasons of battle, I am a Goat Head Warrior.

Stepped on a Goat Head Thorn?

  • Scream. It does help.
  • Do not just grab under your foot to yank it out.
  • Carefully put a finger to each side of it and pull it straight out.
  • Limp to your medicine cabinet/first aid kit and douse the wound in anticeptic, such as hydogen peroxide or medicinal achohol.
  • Apply a layer of antibiotic cream and cover with a sterile bandage.
  • Check it periodically and watch for any sign of infection.

For those of you who walk on areas of your property that have or have had these weeds, be sure to thoroughly wipe your shoes off on a rough surface or mat so you get all the burrs off your shoes. If you don't, you will carry them inside and they will come off on your carpet and you run the risk of stepping on them in bare feet.

The thorns can easily penetrate soft soled shoes and slippers (not to mention tires, in some cases) so really take care to scour your carpeting and floors for them. Animals can bring them in as well. Sometimes I think they make their way in my house on their own.

If you have small children, make sure they always wear shoes in the house, to protect their little feet!

Desert Mallow is a great wildflower that will grow and propagate in your yard, especially if you live in the Southwest.
Desert Mallow is a great wildflower that will grow and propagate in your yard, especially if you live in the Southwest.

For those of you who live in the Southwest USA, the Desert Mallow is a great natural wildflower to promote in your yard. These perennial desert plants flower all summer long, and if you allow them to grow and propagate, they will help choke out the Goat Head Weed. They require nothing, no watering, no fertilizer, just let them flourish and you will have wonderful orange flowers that last and last. They are easily propagated by taking cuttings, if you want to try that, and they reseed each year, naturally multiplying.

I took this picture in my yard, and it's mid May, so you can see they are already flourishing with color.

Unleash the Weevils!

I have read that there is a commercially available weevil available that kills the Goat Head. At this time, I cannot say how effective it is, but I suggest you look into it. I do not believe it would work in my area as I am in a high wind location, and the weevils would be blown away from my yard, helping out my neighbors down wind perhaps, but leaving me open to a rear attack again.

The name of the weevil (which is really a small beetle) is microlarinus lareynii or M. lypriformis.

I cannot say more than to suggest that you research them. Check with the agriculture department in your county to see if it's legal to use!

Never heard them called "goat heads", here in Florida they're known as "sand spurs", and they are what prevent us from "frolicking barefoot through the grass". I love your wit - "the nasty little buggers propagate like randy rabbits," - how descriptive.

How refreshing to see someone suggesting the use or chemical weed sprays. Too often these days it's the opposite.

You are spot on with the line: "But, used properly, and chosen carefully, it's a very helpful weapon in fighting this scourge"

An excellent resource! Goat heads are definitely not things I want anywhere near me... they are rather awful.

I wouldn't want to see the goat heads.

It is amazing that you could find this dreadful weed and emerge victorious. Keep it up.

I have never heard of 'Goat Head Weeds, although we do have stinging nettles in the UK [would they be classed as such?}. Anyway, great lens and very in-depth too. From the sounds of it, it seems that this weed is an absolute nightmare to try to destroy. And to me, it also seems that it serves no purpose at all in your garden, other than taking up space.

lionmom100 3 years ago

At first I thought I had not heard of this weed, being here in the Pacific Northwest, but then it dawned on me that I think I came across it when I lived in So Cal. Nasty little things. I had to laugh at the descriptions of your battles with this devil. But you are fighting a good battle, bring on the big guns (chemicals) when you have to. Now if I could only get rid of this nasty runner borne grass that is snaking its way through my flower beds.

I remember these from growing up in Idaho. Used to get them when I was out exploring. What I have now is an equally hideous invader the MORNING GLORY! I think I have finally eliminated it from my yard. The neighbor behind is the same we are united in our hate of it. But now the guy next to us just doesn't care! Fun to hear that we all have our nemesis (es?) (nemesi?)

I haven't heard of this weed before, it is a very self-protected species with those spears on it. Where I live we have many hard to maintain weeds with thorns and the grow prolifically and cannot be controlled since the climate here is always warm and moist.

Funny, you commented on my lens that had a goat tree in it and now, I am commenting on your goat head lens, ha! My pets bring these things in the house, not sure where they are coming from, I don't have them in the yard. They always end up in my bare feet. These are the most painful things; the pain relates to a needle stick and the bottom of the foot is one of the most sensitive areas of the body.

lgOlson 3 years ago from Northern Arizona Author

@tvyps: The goat head weed is very sneaky. You may not think you have them in your yard, but beware, if they are close by, they will find a way to your property. Even if a thorn falls off your pet, it can grow where it falls.

Yikes! Never had the displeasure of encountering this weed. I'd say it's pretty noxious. From the title I guessed that it was a play on words, and that the solution was going to be an environmentally friendly one --- using goats to chomp them away.

lgOlson profile image

lgOlson 3 years ago from Northern Arizona Author

@lesliesinclair: Well, you can be environmentally friendly by using the propane burner combined with a lot of hard work in pulling them up by the roots, one by one. However, for those like me with thousands of them in my yard, that isn't very realistic if you want to avoid the damage they do.

Hello everyone, Maybe someone could help me. I have what I thought were goat heads growing in our yard. First time. Their massively taking over, about a 4ft. x 10ft patch. Here's the issue I'm having now though. As of today I don't actually know if what we have are goat heads. The leaves look identical to the goat heads but they have purple flowers not yellow flowers. From all the photos that I have seen of goat heads they have yellow flowers, not purple flowers. If someone can help me identity what I have I would very much appreciate it. Thank you

becky-roberts-520 2 years ago

Hello Everyone, Here's my dilemma/ I have a patch of what I thought were goat heads growing in our yard/mixed in with the grass. A 4ft. x10ft. patch. The leaves look identical to goat heads but what we have has purple flowers, not yellow flowers. Do goat heads have more than one color of flower? I am in process of getting rid of them now before they get out of hand. Any help, suggestions would much be appreciated. Thanks so much

I hae been doing battle with these things ever since I bought tis place from my parens estate. I did discover while working in New Mexico that Fertiloam puts out a dry pre-emergent call Avert. I had never seen it in Colorado. It cannot be found at the big box stores-- Find a small farmer type feed store that carries Fertiloam products. Its doesn't rid you of the goathead stickers but it keeps them from germinating. Wish I had bought several bags and you can be when I get back thru N M I will stock up--I does work.

I've found a new tool for grasping them way down low to the ground to pull them out - Lawn Jaws, sold on Amazon.

I'm in Phoenix and have desert landscaping, so large gravel areas. To find the goathead burrs to eliminate them in the gravel , I walk around the yard in soft flip flops. They will embed themselves in the soles, and I pull them out and repeat.

Hi there. Wow! And here I thought we only get it in South Africa, Cape Town. Interesting read. My front yard has been left bare due to home improvements some time now. However we just scoop up the weeds every time we see them surfacing. The yard is all clean until i walk with my flip flops and before i enter my home I look under my soles and it's fully loaded with these devil thorns. There's no other way but to remove it individually off my flip flops cussing as I do

A lot of words. Eliminate annual one needs to dig it, burn it, poison it and don't let it go to seed. Seeds lay in the ground viable for many years, and new seed are brought in on the feet and shoes of any thing that walks through, therefore it will take a long time. So often some plants survive to reseed the following year.

middle of az 7 weeks ago

The seeds can survive several years in the ground before they sprout. Don't let them grow big enough to produce seeds. I wander around my yard with a hoe and when I see that little yellow flower I attack. I have a lot less then before. The problem is the neighbors don't do anything about them. Each big rain just wash more seeds into my yard.
