You pull dandelions out by hand, and they just grow back from the deep taproot you missed. A chemical spray kills that root in one go without ruining your lawn, but pick the wrong bottle and you waste money or damage your grass. This guide compares the specs of four different sprays so you see which one fits your yard.

How To Choose The Best Spray For Dandelions
Not every weed killer behaves the same in your yard. The wrong choice can kill the dandelion but also damage your grass, or it can be too weak to reach the deep taproot (the thick root that grows deep into the soil). Here are the three things to check before you buy.
Selective vs. Non-Selective Formulas
A selective weed killer targets broadleaf weeds like dandelions and clover while leaving your lawn grass unharmed. A non-selective formula kills every green thing it touches. For spot-treating dandelions in a lawn, always choose a selective herbicide (a chemical that kills specific plants) — look for labels that list “won’t harm grass” or explicitly name safe turf types.
Ready-to-Use vs. Concentrate
Ready-to-use bottles come pre-mixed with a sprayer or wand — grab one, pull the trigger, and you are done. Concentrates (a liquid you must dilute with water) require mixing with water in a tank sprayer but give you far more coverage per dollar. A 1-gallon (128 fluid ounce) ready-to-use container covers 5000 sq ft for the Ortho refill, while a 1-quart (32 fluid ounce) concentrate like the Albaugh covers 16,000-32,000 sq ft after dilution.
Speed of Results
Some formulas show wilting in hours; others take a week or two to fully kill the root. If you want visible die-off fast, look for a dehydrating formula (a spray that dries out the plant) or one with triclopyr and dicamba (chemicals that target broadleaf growth). If you are patient and want total root kill with fewer applications, a slower systemic herbicide (a chemical that moves through the plant to kill the root) wins the long game.

In‑Depth Reviews
1. Ortho WeedClear Weed Killer for Lawns Refill
The 128 fluid ounce (1 gallon) jug refills your existing sprayer wand so you keep paying the lowest price per ounce.
This is the refill — a 128-fluid-ounce jug of concentrate (you pour it into your old Ortho Comfort Wand applicator). Buyers report it “destroys flower weeds without killing the grass,” noting that a little goes a long way. The formula is designed to kill over 250 types of weeds — including dandelion and clover — right down to the root in one application when used as directed.
The catch is you need the separate Comfort Wand sprayer to apply it. If you are starting from zero, the ready-to-use version below makes more sense. But if you already own the wand, this refill gives you 128 fluid ounces for about half the price of one ready-to-use bottle. At 128 fluid ounces versus the Albaugh’s 32 fluid ounces, it offers more liquid in the bottle. Its listed item weight is 1 ounce, versus the Spruce kit’s 5.43 pounds.
It works on a long list of grass types including St. Augustinegrass (not Floratam, a specific variety), Bermudagrass, Centipedegrass, Zoysiagrass, Kentucky Bluegrass, and Fescues. Apply when daytime temperatures stay below 90°F. One jug covers 5000 square feet, while the Spruce kit is rated for up to 400 weeds.
Repeat-buy from a longtime user: One reviewer noted “Been using for years, still has some trioxide (a weed-killing chemical) which is a great weed killer and lasts awhile” — confirming this is a dependable choice for ongoing dandelion battles.
Reach for this if: you already own a Comfort Wand and want the lowest cost per ounce for tackling dandelions across a 5000 sq ft lawn. Compared to the ready-to-use Ortho, this gives you more liquid for less money per gallon.
Look elsewhere if: you need a complete spray system from the start — the Ready-to-Use version below includes everything.
2. Ortho WeedClear Lawn Weed Killer Ready-to-Use with Comfort Wand
The full kit gives you a battery-powered wand and a gallon of killer, so dandelions stop growing within 2 days — no measuring, no mixing.
This 1-gallon (128 fluid ounces) ready-to-use bottle comes with a battery-powered Comfort Wand sprayer (a handheld wand that sprays the chemical). You open the box, insert the included batteries, and start spraying immediately. One buyer mentioned that “within 2 days, dandelions stopped growing tall; within 2 weeks, 85% of weeds were dead/brown” — and that was on a lawn overtaken by dandelions from a neighboring field. The selective formula (kills broadleaf weeds, leaves grass alone) targets dandelion, crabgrass, clover, chickweed, and creeping charlie down to the root without harming listed lawn grasses like Bermudagrass, Buffalograss, Fescues, Kentucky Bluegrass, Ryegrass, and Zoysiagrass.
The wand has two spray settings — a stream for precise spot treatment and a wider fan for covering patches. It comes with 128 fluid ounces, versus the Spruce kit’s 64 fluid ounces, and unlike the Albaugh concentrate, there is no dilution math or tank sprayer needed. Apply to young, actively growing weeds in spring or fall for best results.
Not every reviewer loved it — one called it the “worst weed killer ever” and said weeds took forever to wilt. The difference is usually how heavily you spray. The product works by lightly coating the weed leaves, not drowning them. Buyers who saw slow results often used too little or sprayed in hot, dry conditions.
What works
- Comes with battery-powered Comfort Wand — ready to use from the start
- Targets dandelions and over 250 other weeds without killing lawn grass
- 128 fluid ounces gives you a full gallon of coverage
- Visible results within 2 days on actively growing weeds
The trade-offs
- A few owners mention slow wilting — likely due to under-spraying the leaves
- Not compatible with St. Augustinegrass (Floratam variety)
- Batteries included but may run out mid-treatment on a large yard
For the first-time buyer: this is the most complete dandelion solution — sprayer, chemical, and gallon of coverage in one box. The price-per-ounce is higher than the refill jug, but you get everything you need.
Honest limit: if you have a very large property over 5000 sq ft, the Albaugh concentrate below will be more economical because one quart covers 32,000 sq ft.
3. Albaugh Sublime Weed Killer
One 32-fluid-ounce bottle of concentrate covers 16,000-32,000 square feet, while the Ortho gallon refill covers 5000 square feet.
If you have a large property, this is your pick. One 32-fluid-ounce bottle of Albaugh Sublime concentrate covers 16,000 to 32,000 square feet, while the Ortho gallon refill above covers 5000 sq ft. The active ingredients are triclopyr, dicamba, and mesotrione (three different herbicides that work together to target broadleaf weeds while leaving grass unharmed). This blend is designed for selective control over dandelions, crabgrass, creeping charlie, chickweed, clover, and many other tough weeds. A reviewer noted “effective on chickweed, dandelion, crabgrass, clover” and reported visible wilting in three days of 85°F sun, with near-total weed elimination in about 2.5 weeks.
It is designed for ornamental turf lawns (lawns grown for their appearance), golf courses, parks, athletic fields, and sod farms. The “no bleaching” formula means your grass stays green while the dandelions die — unlike cheaper chemicals that leave white streaks on the turf. Unlike the Ortho products that are selective only for specific lawn grasses, Albaugh works across residential and institutional settings. The bottle is listed at 32 ounces, versus the Ortho refill’s listed 1-ounce item weight.
The real catch is patience. Several buyers warn “be patient, takes a week or two to really work.” The same reviewer who saw wilting in 3 days said full control took 10 days for major reduction. This is a systemic herbicide (works from inside the plant) — not a one-hour weed killer. Also, one reviewer found it ineffective on wild violets, so if that is your main weed, the Spruce kit below acts faster.
Buyer tip for precision: one verified owner recommends using a laser blue indicator dye (a coloring agent that shows where you sprayed) to track your application — “a small dab leaked out” in packaging, so store the bottle upright and consider decanting into a dedicated sprayer.
Best for: the owner of a large lawn who wants to mix their own strength and cover 16,000-32,000 sq ft per quart.
Skip if: you want instant results or have wild violets as your main target — the Spruce kit below acts faster in hours, not weeks.
4. Spruce Weed Killer Spray Power Wand Kit
The 64-fluid-ounce kit uses essential oils and a surfactant (a substance that helps the spray stick to leaves) to kill weeds in 1-2 hours — and it is safe around pets.
If you have dogs, cats, or a pollinator-friendly yard, this is the dandelion spray that does not force you to choose between weeds and safety. The formula uses water, essential oils, and surfactant (a substance that helps the spray stick to leaves) rather than harsh traditional chemicals. One owner reported it “kills weeds in 24 hours, pet/pollinator-safe, directed spray, no jamming, pleasant mint scent” — another said it killed weeds in 2 hours with browning complete in 24 hours. The reusable wand comes with two additional AA batteries included, and Spruce rates the sprayer for up to 5 years of use (based on 20 uses per year).
The kit treats up to 400 weeds per bottle. It works on all types of broadleaf and grassy weeds including dandelions, large crabgrass, white clover, dollarweed, and morning glory vines. The spray pattern is directed and the wand does not jam — a common complaint with other battery-powered sprayers. At 5.43 pounds, it is the heaviest item in this roundup — heavier than the Ortho gallon jug (1 ounce shipping weight) and the Albaugh quart (32 ounces) — because the bottle is full of liquid and the wand and batteries are included.
The trade-off is coverage area: 64 fluid ounces treats 400 weeds, which is a smaller job than the Albaugh’s 32,000 sq ft. For a very large lawn, you would need multiple bottles. A few buyers also note the herbal smell is strong — “smells like lemon pledge” according to one. For best results, apply in sunny, dry conditions.
Why it stands out
- Safe around people, pets, and bees when used as directed
- Visible results in 1 hour, dead weeds in 24 hours
- No mixing, no measuring — ready to use with battery-powered wand
- Pleasant mint or lemon scent instead of chemical odor
The limitations
- Only 64 fluid ounces — less coverage than Ortho’s gallon for the price
- Strong herbal scent might not suit everyone
- Works best in sunny, dry conditions — rain can wash it off
Grab this if: you have dogs, cats, or a pollinator-friendly yard and want a non-toxic dandelion killer that works in one day. It acts faster than the Albaugh’s weeks-long process.
Pass on it if: you need to treat a whole acre cheaply — the Albaugh concentrate covers 32,000 sq ft per quart, far more ground than the Spruce’s 400-weed limit.
Understanding the Specs
Active Ingredients
This is the chemical or natural compound that actually kills the dandelion. Common active ingredients in selective herbicides (weed killers that target broadleaf plants) include triclopyr, dicamba, and mesotrione — these target broadleaf weeds and leave grass unharmed. Natural formulas use essential oils and surfactant (a substance that helps spray stick to leaves) to dehydrate the plant (dry it out). The ingredient type determines how fast it works and whether it is safe for pets and pollinators.
Liquid Volume & Coverage
Liquid volume is the amount of product in the bottle, measured in fluid ounces (fl oz). Coverage is the area the product can treat — usually listed in square feet (sq ft) for concentrates (after mixing with water) or number of weeds for ready-to-use sprays. A 32-ounce concentrate may cover 32,000 sq ft, while a 64-ounce ready-to-use bottle may only cover 400 weeds. Always check both numbers so you do not run out mid-yard.
