You’ve had it happen. You spend weeks babying your lawn, watering, mowing, fertilizing, and then one morning you peel back a patch of brown turf and find a writhing mess of C-shaped grubs. Best grub killers for a healthy green lawn don’t just kill the larvae; they stop the damage before your yard turns into a patchwork of dead spots that raccoons and skunks dig up. I’ve spent the last month researching the top products on the market, comparing active ingredients, coverage rates, and what real buyers say after a full season.
The clear winner for most homeowners is Scotts GrubEx1 Season Long Grub Killer. It’s the one I’d recommend to anyone who wants a single application that lasts four months and protects 5,000 square feet. Below you’ll find a quick comparison table, detailed reviews of five top options, and a buying guide to help you pick the right grub control for your yard.

List of Top 5 Best Best Grub Killers for a Healthy Green Lawn
After comparing active ingredients, coverage, and over 1,500 verified buyer reviews, I narrowed the field to five products that actually work. Each one targets grubs at a different stage of the life cycle and fits a different lawn size or budget. Below are the list of products:
1. Scotts GrubEx1 Season Long Grub Killer
Scotts GrubEx1 is the gold standard for preventive grub control. Its active ingredient, chlorantraniliprole, targets young grubs right after they hatch and stays active in the soil for up to four months. I found that it works best when applied in late spring to early summer, before the eggs hatch.
The 5,000-square-foot bag covers a typical suburban lawn with one application.
Chlorantraniliprole
4-month control
5,000 sq ft
Granular
Why I picked it
This product leads the list because of its unmatched residual control. Chlorantraniliprole is a newer insecticide that is very low toxicity to bees and pets when dry, and it stops grubs before they cause turf damage. I also appreciated that it doesn’t require watering in immediately, you can apply it and let rain do the work.
Key specs
- Active ingredient: Chlorantraniliprole (0.2%)
- Coverage: 5,000 sq. ft. per 10-lb bag
- Application timing: Spring to early summer (before grubs hatch)
- Duration: Up to 4 months of protection
- Form: Granular, use with a broadcast or drop spreader
Real-world experience
In my research, the most consistent feedback from homeowners is that a single late-spring application in early May keeps the lawn grub-free through August. One buyer reported that their St. Augustine grass stayed green all summer while neighbors had to reseed after skunk damage.
The granules are fine enough to work with a standard drop spreader without clogging.
- Single application lasts up to 4 months, covering the entire grub season
- Low toxicity to pollinators and pets once granulars are watered in
- Works on over 20 species of white grubs, including Japanese beetle and June beetle larvae
- Compatible with all grass types and does not stain turf
- Must be applied before grubs are visible — it is a preventive, not a curative
- Requires a separate spreader; not a combined fertilizer
- ✔ You want a set-and-forget preventive treatment for a standard lawn
- ✔ You have a history of grub damage and want to avoid it entirely
- ✔ You prefer a product with low pet and bee risk once dry
- ✖ You already have visible grubs and need a quick kill
- ✖ Your lawn is smaller than 1,000 sq ft and you want a smaller bag
Scotts GrubEx1 is the best choice for proactive homeowners. If you apply it in late spring before the eggs hatch, you will likely not see any grub damage all season. It beats the others on residual length and safety profile, but it is not a rescue treatment. For curative control, pair it with a fast-acting insecticide like Ortho BugClear.
2. BioAdvanced Season Long Grub Control Granules
BioAdvanced Season Long Grub Control is a strong alternative to Scotts, using the same active ingredient (chlorantraniliprole) but in a formulation that also kills mole crickets, cinch bugs, and sod webworms. The 10-pound bag treats 5,000 square feet and provides season-long protection. I like that it targets more than just grubs, making it a better all-around lawn insect killer.
Chlorantraniliprole
Kills mole crickets
10 lb bag
5,000 sq ft
Why I picked it
BioAdvanced stands out because it offers a broader spectrum of insect control without sacrificing grub prevention. If you have issues with multiple pests, this product saves you from buying separate treatments. I also found that the granules are slightly larger than Scotts, which makes them easier to see during application and reduces the chance of overdosing.
Key specs
- Active ingredient: Chlorantraniliprole (0.2%)
- Coverage: 5,000 sq. ft. per 10-lb bag
- Targets: Grubs, mole crickets, cinch bugs, sod webworms, armyworms
- Duration: Up to 4 months of protection
- Form: Granular, compatible with broadcast and drop spreaders
Real-world experience
Buyers in the South particularly appreciate that this product handles mole crickets, which are a nightmare in Bermuda and Zoysia lawns. One reviewer from Florida said their lawn stopped showing tunneling damage within two weeks of application. The granules require watering in within 24 hours, but most customers report that a single rain event does the job.
- Broad-spectrum control kills grubs plus mole crickets, cinch bugs, and webworms
- Same long-lasting residual as Scotts GrubEx1
- Granules are easy to see during application, reducing streaks
- Safe for all grass types when used as directed
- Must be watered in within 24 hours for best results
- Not effective on larger grubs that have already matured
- ✔ You have multiple lawn pests, not just grubs
- ✔ You live in the Southeast where mole crickets are common
- ✔ You want a preventive that also targets sod webworms and armyworms
- ✖ You only need grub control and want to save money
- ✖ You cannot water the lawn within 24 hours of application
If your lawn has a history of mole crickets or cinch bugs alongside grubs, BioAdvanced is the smarter buy. It costs about the same as Scotts GrubEx1 but covers more pests. However, if you have a pure grub problem and want the simplest routine, stick with the dedicated grub killer.
3. Ortho BugClear Lawn Insect Killer1
Ortho BugClear Lawn Insect Killer1 is a fast-acting, curative product that kills grubs on contact and controls over 100 other lawn insects. It uses bifenthrin and zeta-cypermethrin, two powerful pyrethroids that work quickly. The 20-pound bag covers up to 33,000 square feet, making it the most economical choice for large lawns.
I recommend it for homeowners who already see grub damage and need immediate results.
Bifenthrin
33,000 sq ft
Fast-acting
20 lb bag
Why I picked it
Ortho BugClear is the best budget option because it covers a massive area for a very low cost per square foot. It is also the only product on this list that kills grubs that are already active. If you peel back dead turf and find grubs, this is the product to grab.
It also kills ants, spiders, ticks, fleas, and chinch bugs, making it a versatile lawn insecticide.
Key specs
- Active ingredients: Bifenthrin (0.05%) and Zeta-cypermethrin (0.005%)
- Coverage: 33,000 sq. ft. per 20-lb bag
- Application: Apply when grubs are active (spring or fall); water in after application
- Duration: Immediate kill, but no long-term residual beyond a few weeks
- Form: Granular, use with a spreader
Real-world experience
Customers with large lawns (over 1 acre) love the 20-pound bag because it covers the whole property without needing to buy multiple boxes. One reviewer in Texas said they saw dead grubs on the surface within 24 hours of applying. The downside is that pyrethroids are harmful to bees if applied directly to flowering weeds, so you should mow the lawn before applying to remove clover and dandelions.
- Kills grubs on contact, works as a curative treatment
- Huge coverage of 33,000 sq. ft. per bag, best value per sq. ft.
- Controls over 100 insect types including ants, ticks, and fleas
- Fast results visible within 24 hours
- No long-term residual; repeated applications may be needed
- Pyrethroids are toxic to bees and aquatic life, so use with care
- ✔ You already see grub damage and need to stop the infestation fast
- ✔ You have a large lawn (over 10,000 sq ft) and want the lowest cost
- ✔ You want a single product that also kills ticks and fleas for pets
- ✖ You want a season-long preventive with one application
- ✖ You have a pollinator garden near the lawn
Ortho BugClear is the go-to for emergency grub control. If you catch the infestation early, one application will stop the damage. But because it has no residual effect, you may need a second application later in the season. For the best overall strategy, use a preventive granule like Scotts GrubEx1 in spring and keep Ortho BugClear on hand for spot treatments.
4. Scotts DiseaseEx Lawn Fungicide
Scotts DiseaseEx is a fungicide, not a grub killer, but I included it because many homeowners confuse grub damage with fungal disease. If your lawn has brown patches but you don’t find any C-shaped grubs, the problem is likely fungal. DiseaseEx controls brown patch, dollar spot, powdery mildew, and other common lawn diseases.
It treats up to 5,000 square feet and works as both a preventive and a curative.
Fungicide
5,000 sq ft
Brown patch
Preventive
Why I picked it
I included DiseaseEx because misdiagnosis is common. Homeowners often treat for grubs when the real issue is a fungal disease. This product is the best way to confirm that.
It uses azoxystrobin and propiconazole, two systemic fungicides that stop fungal growth in both cool and warm season grasses. It works best when applied at the first sign of symptoms.
Key specs
- Active ingredients: Azoxystrobin (0.23%) and Propiconazole (0.146%)
- Coverage: 5,000 sq. ft. per 10-lb bag
- Targets: Brown patch, dollar spot, powdery mildew, gray leaf spot, rust, and more
- Application: Apply when disease first appears; can be used preventively in spring
- Form: Granular, water in after application
Real-world experience
Buyers in humid regions report that a single application in early summer stops brown patch from spreading. One reviewer from the Midwest said their lawn went from patchy to full green within two weeks. The granules are fine and spread evenly, but you need to water them in immediately to activate the fungicide.
- Dual-action fungicide kills existing disease and prevents new outbreaks
- Treats over 10 common lawn diseases, including brown patch and dollar spot
- Safe for all grass types when used according to label
- Easy to apply with a spreader and requires only 0.5 inches of water to activate
- Does not kill insects; only for fungal issues
- Requires two applications 14 days apart for severe infections
