Sticker Burrs in Your Lawn? Here's How to Get Rid of Them

Quick answer: Sticker burrs are the spiny seed pods of a handful of weeds, mainly sandbur (grass burrs), lawn burweed, puncturevine, and burclover. They show up where turf is thin, soil is sandy, dry, or compacted, and a pre-emergent was skipped or applied at the wrong time. Pulling the plants won't fix it on its own, because each one leaves a seed bank behind. The fix is a properly timed pre-emergent, a selective post-emergent while plants are young, and a thicker turf so the seeds have nowhere to land.

If you've ever walked barefoot across your yard and found yourself hopping on one foot, you already know the problem. What most people don't realize is that "stickers" aren't one weed. They're several different plants that just happen to share a nasty habit, and each one grows at a different time of year. Get the timing wrong and you'll be fighting the same patch every season.

Let's sort out which one you've got, what's inviting it in, and how to get rid of it for good.

What Are Sticker Burrs, Exactly?

A burr is a seed (or a cluster of seeds) wrapped in a hard, spiny case. The spines aren't there to annoy you specifically; they're there to hook onto fur, socks, shoes, and tires so the seed gets carried somewhere new. Every burr your dog brings in on its paws is a plant's way of planting next year's crop.

That's the first thing to understand about any burrs plant: the burr is the end of the story, not the beginning. By the time you're stepping on them, the plant has already done its job. Real control happens weeks or months earlier.

Types of Stickers in Grass: Which One Do You Have?

There are four types of burr weeds that cause most of the trouble in home lawns. Here's how to tell them apart.

1. Sandbur (Grass Burrs or Sandspurs)

What it is: Sandbur (Cenchrus species) is an annual grass, not a broadleaf weed, and that matters a lot when it comes to control. Southern sandbur (Cenchrus echinatus) and field sandbur are the usual suspects, and you'll hear them called grass burrs, sandspurs, or just "stickers," depending on where you live.

How to spot it: As a seedling, it blends right into your lawn with flat blades that feel like sandpaper on the upper surface. You often won't notice it until late summer, when it sends up spiky seed heads covered in round, tan burrs with flattened spines. The seed heads are 3 to 14 cm long, with a ring of fine bristles at the base of each burr.

When it shows up: It germinates from late spring into late summer and keeps growing until the first hard freeze. Burrs appear in summer and fall, which is exactly when you're spending the most time outside.

Because sandbur looks so much like grass early on, it's easy to miss. If you're having trouble telling it apart, our guide to weeds that look like grass walks through the tells.

2. Lawn Burweed (Spurweed or "Stickerweed")

What it is: Lawn burweed (Soliva sessilis) is the sticker weed in lawns across the Southeast that ruins spring barefoot season. It's a low, ferny-looking broadleaf winter annual.

How to spot it: Small, finely divided leaves that look a little like parsley or carrot tops, hugging the ground. The spines form in the leaf joints, right down at the soil level, which is why you feel them before you ever see them.

When it shows up: This is where it catches people out. According to UGA Cooperative Extension, lawn burweed germinates in the fall as soil temperatures drop, stays small and unnoticed all winter, starts forming burrs in March, and has hardened spines by April. By the time you're stepping on them, herbicides won't help that season.

3. Puncturevine (Goatheads)

What it is: Puncturevine (Tribulus terrestris) is a summer annual broadleaf that forms flat, spreading mats. It's the one that flattens bicycle tires, and it's most common in the dry West and Southwest.

How to spot it: Trailing stems with small, paired leaflets, little yellow five-petaled flowers, and hard, woody burrs that split into sections, each carrying a pair of sharp spines about half an inch wide.

When it shows up: Through the warm months until frost. It loves disturbed, bare ground: driveway edges, sidewalk strips, and worn spots in the lawn.

Why it's so stubborn: Viable seeds can stay dormant in the soil for up to 20 years. One season of neglect can mean years of cleanup.

4. Burclover

What it is: Burclover (Medicago polymorpha) is a clover-like legume with three-toothed leaflets and small yellow, pea-type flowers.

How to spot it: The giveaway is the seed pod. University of Arizona Extension's plant profile describes pods that start green and soft, then turn brown and hard, coiled into two or three spirals with rows of hooked prickles. They cling to socks and pet fur like nobody's business.

When it shows up: It blooms in spring, from roughly March to June, and the hardened pods hang around well after.

Burrs Beyond the Lawn

You'll also see burrs from plants like cocklebur, burdock, and beggarticks around fence lines, field edges, and wooded borders. They're mostly a problem in unmowed areas rather than in maintained turf, since regular mowing keeps them from setting seed. If they're showing up in the lawn itself, that's usually a sign the edges need attention as much as the grass does.

What Causes Sticker Burrs in a Lawn?

Here's the honest answer: sticker weeds in a lawn are almost always a symptom, not the root problem. They're opportunists. They move in where your grass has left the door open. These are the most common reasons.

Thin or Bare Turf

This is the big one. Every one of these weeds needs sunlight hitting bare soil to germinate. A thick, healthy lawn shades the soil surface and leaves no room. Sandbur is generally not a problem in well-maintained turf, and planting competitive grasses as a long-term fix for puncturevine. Fill the gaps and the stickers have nowhere to land.

Sandy, Dry, or Low-Fertility Soil

Sandbur earned its name: it's especially well adapted to dry, sandy soils. Those same soils drain fast, hold few nutrients, and struggle to support thick turf, which is a double win for the weed. Burclover, as a legume, makes its own nitrogen, so it can hold its own in lean soil where your grass is going hungry.

Not sure what your soil is short on? Our guide on what weeds tell you about your soil health is a good place to start, and if your sandy soil seems to shed water instead of soaking it up, check for the signs your lawn soil has gone hydrophobic.

Compacted, High-Traffic Areas

Puncturevine in particular loves hard, beaten-down ground: the path the dog runs along the fence, the strip next to the driveway, the spot where the kids play ball. Grass roots struggle in compacted soil, the turf thins out, and the weeds take over.

Mowing Too Low

Scalping the lawn opens the canopy, lets sunlight reach the soil, and stresses the grass all at once. A higher mowing height can lead to fewer sandbur problems. If you've been cutting short to stretch the time between mows, that may be part of the story. (Already scalped it? Here's what to do next.)

Shallow, Frequent Watering

Light daily sprinkling keeps the top half-inch of soil moist, which is perfect for weed seeds and bad for deep grass roots. As always, I recommend watering deeply and less often instead.

Missing (or Mistimed) Pre-Emergent

This is the one that catches most homeowners out. People see burrs in spring and put down a pre-emergent then, but lawn burweed germinates back in the fall. Or they apply for crabgrass in early spring and assume it'll cover sandbur all summer, when sandbur keeps germinating into late summer. A pre-emergent only works on seeds that haven't sprouted yet, so the calendar is everything.

Hitchhiking Seeds

Burrs are built to travel. They come in on dogs, shoes, mower wheels, tires, and sometimes contaminated topsoil or hay. Once they're in, every burr that drops adds to the seed bank in your soil.

Golf Course Lawn Tip: Clean your mower deck and wheels after cutting a sticker-infested area. Otherwise, you're running a seed-delivery service straight to the clean parts of your lawn.

How Do You Get Rid of Grass Burrs?

Sandbur is the hardest of the bunch, because it's a true grass. Most weed killers that are safe on your lawn are designed to leave grasses alone, so they leave sandbur alone too. Here's how to get rid of grass burrs in the right order.

Step 1: Stop the Seeds with a Pre-Emergent

This is the most effective tool you have. Apply when soil temperatures reach about 52°F, roughly two to four weeks before germination, and water it in thoroughly. A second application six to nine weeks later may be needed for season-long control, since sandbur keeps germinating well into summer.

For warm-season lawns, Specticle® FLO lists sandbur on its label, along with lawn burweed, puncturevine, and California burclover, which makes it the closest thing to an all-in-one sticker preventer. It's applied once a year, in late summer or early fall, and needs about 1/4" of irrigation or rain to activate. Warm-season grass only; don't use it on cool-season lawns.

specticle-flo-pre-emergent-herbicide

Prodiamine is one of the best for sandbur pre-emergent control, and it's labeled for both warm and cool-season grass, so it's the go-to for Fescue and Bluegrass lawns. Pick the format that suits you: a sprayable concentrate or a granular with fertilizer you can put down with a spreader.

Step 2: Hit Young Plants Hard, If Your Grass Allows It

Selective post-emergent options for sandbur are limited, and they depend heavily on your grass type. NC State Extension points to sethoxydim as very effective on sandspur in Centipedegrass only (it will kill Bermuda). Whatever you use, it needs to go on while plants are small and actively growing, long before burrs form.

Step 3: Remove the Burrs You Missed

If the plants have already set seed, don't just leave them. Mow low with a bagger to collect the seed heads, or drag an old blanket or towel across the area to pick up loose burrs. Bag them and bin them. Every burr you remove is one fewer plant next year.

How to Get Rid of Sticker Burrs in Your Yard (Broadleaf Types)

Lawn burweed, puncturevine, and burclover are broadleaf weeds, which makes them much easier to control. A selective broadleaf herbicide will take them out without harming your grass, as long as you match the product to your turf type and get the timing right.

Lawn Burweed: Think Halloween and Valentine's Day

This is a handy way to remember lawn burweed timing:

• Pre-emergent around Halloween (late September to mid-October), before the seeds germinate. Prodiamine is the top choice.

• Post-emergent around Valentine's Day, when plants are visible but haven't formed burrs yet. 2,4-D, three-way products (2,4-D, dicamba, MCPP), and metsulfuron are good options. A mid-to-late March application can still help if the spines haven't hardened.

Treating consistently for at least two consecutive years will wear down the seed bank.

For warm-season lawns, Bermuda, Zoysia, St. Augustine, and Centipede a three-way broadleaf herbicide does the job on young burweed, puncturevine, and burclover. Celsius WG combines Iodosulfuron-methyl-sodium, Thiencarbazone, and Dicamba to pack a mean punch while being safe for your warm season grass.

Tenacity® lists lawn burweed on its label and works as both a pre and post-emergent. It's labeled for cool-season grasses and Centipede, making it a useful option for Centipede lawns where three-way products are off the table. Don't use it on Bermuda or Zoysia.

Golf Course Lawn Tip: If you're spraying once a year, February is the month to do it, with a post-emergent and pre-emergent together. And skip high-nitrogen "weed and feed" products at that time of year: your warm-season grass is still dormant, so you'd mostly be feeding the weeds.

Puncturevine: Get It Before It Flowers

Puncturevine can flower within weeks of sprouting, so speed matters. Hand pulling or hoeing works well on small patches (it has a single taproot, so it comes out cleanly in moist soil), but wear heavy gloves once burrs have formed. For bigger infestations, a 2,4-D-based broadleaf herbicide applied to young plants is effective, and a spring pre-emergent stops the next flush. Then fix whatever left the ground bare in the first place.

Burclover: Spray Before the Pods Harden

Treat burclover in early spring while the plants are small and before those coiled pods form. The same selective broadleaf products work here. Longer term, a lawn that's fed properly will crowd it out, since burclover has an advantage in lean soil.

For a wider look at selective options, see our roundup of the best products for killing weeds without killing grass. And if you're spraying, a backpack sprayer vs. a hose-end sprayer makes a real difference to accuracy.

How to Prevent Sticker Burrs from Coming Back

Killing this year's stickers is only half the job. If the conditions that invited them remain, they'll be back. Here's how to break the cycle for good.

• Test your soil. Sandy and lean soil is the root cause of many sticker problems. A soil test tells you exactly what's missing, so you're not guessing.

mysoil-starter-pack

• Feed the grass, not the weeds. A balanced fertilizer at the right time of year thickens turf so there's no bare soil left for seeds to land on.

lebanon-country-club-complete-fertilizer-14-7-14-sgn-80

• Overseed the thin spots. Once the weeds are gone, don't leave bare patches behind. I recommend reseeding weak turf, since removing weeds alone just leaves space for the next batch. Match your seed to your existing grass from our grass seed collection. (Remember that a pre-emergent will stop grass seed too, so check the label for the waiting period before overseeding.)

• Raise your mowing height. Taller grass shades the soil and keeps weed seeds from sprouting.

• Water deeply and less often. Deep watering builds deep roots; frequent shallow watering grows weeds. 

• Aerate compacted areas. Relieving compaction helps grass fill back in on high-traffic paths where puncturevine likes to settle.

• Mark your calendar. Fall for lawn burweed pre-emergent. Late winter or early spring for sandbur and puncturevine. February for burweed post-emergent.

Golf Course Lawn Tip: Pre-emergents need water to activate. Insufficient watering-in is one of the main reasons pre-emergent applications fail, so if rain isn't in the forecast, give it about 1/4" of irrigation yourself.

FAQs

How do I get sticker burrs out of my dog's paws and fur?

Check between the toes and pads first, since that's where burrs tend to lodge. Pull them out with tweezers or a fine-toothed comb, working from the base of the fur rather than tugging, and wear gloves so you don't end up with spines in your own fingers. If your dog keeps limping or licking a paw afterward, or you can't get a spine out cleanly, have your vet take a look.

What's the easiest way to get burrs off socks, clothes, and blankets?

Pick off the big ones by hand while wearing gloves, then run a stiff brush or a lint roller over the fabric to catch the smaller fragments. Shake items out outdoors, over a trash bag rather than the lawn, so you aren't scattering seeds back into the yard. Running burr-covered fabric straight through the washer usually just sends the spines deeper into the weave.

Will vinegar or boiling water kill sticker weeds?

They'll burn the top growth, but they aren't selective, so they'll damage your grass just as fast as the weed. They often don't kill the roots either, and they do nothing to the seeds already in the soil. They're fine for a sticker patch in a gravel path or sidewalk crack, but they're a poor choice inside the lawn itself.

Can I burn off sticker burrs with a weed torch?

A propane weed burner can reduce the number of viable puncturevine seeds on the soil surface, but you should check with your local fire department before using one. Never use one on dry grass or during a burn ban, and keep it off the lawn itself, since it will scorch your turf along with the weeds.

Is it okay to put sticker burr plants in the compost pile?

It's safer not to. A backyard compost pile often doesn't get hot enough, evenly enough, to kill every seed, so you can end up spreading next year's stickers across your garden beds with the finished compost. Bag the plants and burrs and put them in the trash instead.

Is there an organic way to get rid of sticker burrs?

Your best organic tools are cultural, not chemical: thicken the turf, raise your mowing height, water deeply and less often, pull young plants before they set seed, and collect any burrs that drop. Most organic weed sprays are non-selective, so they'll harm grass along with weeds. Expect it to take a few seasons to wear down the seed bank this way.

Are there any natural predators that eat puncturevine?

Yes. Two weevils, a seed weevil (Microlarinus lareynii) and a stem weevil (Microlarinus lypriformis), feed on puncturevine and have been released as biological controls in the western US. They may not be present in your area and may not survive cold winters, so treat them as a helpful extra rather than a stand-alone fix.

The Sticking Point

Sticker burrs are your lawn's way of telling you there's room for something to move in. Figure out which weed you're dealing with, get the timing right (fall for burweed, late winter or spring for sandbur and puncturevine), and fix whatever thinned out the grass in the first place. Do that for a couple of seasons, and barefoot weather won't come with a warning attached.
