Best Grub Killer For Fall: Compare 10 Lawn Treatments

#1 · Best Overall

1. St. Gabriel Milky Spore

• Weight: 15 lb
• Form: Granules

Best for: Organic multi-season grub plan.

Why it ranks #1: Its directions explicitly include fall applications, alongside spring and summer, for two consecutive years; this is the clearest stated fall schedule in the lineup.

USDA-certified organic ingredients and application by spreader or hand make St. Gabriel Organics Milky Spore a granular option for buyers prioritizing a natural-ingredient treatment. Its directions specify applications in spring, summer, and fall for two consecutive years, making the plan a sustained commitment rather than a single fall pass.

The product is described as working continuously throughout the year and regardless of weather, while its application directions call for six total treatments over two years on unfrozen ground. That schedule has a practical planning impact: users need to return in each listed season rather than rely on one application. Granules can be spread by hand or with a spreader, offering two application methods. Its organic and non-toxic claims address use around food crops and residential areas, while directions still say to keep it out of children’s reach.

Skip it if you want a single seasonal application; BioAdvanced Season Long Grub Control lists one application for season-long protection.

This fits buyers choosing a USDA-certified organic granular approach and willing to follow the full two-year schedule. Its spreader-or-hand application offers flexibility, but the six-treatment plan is a key boundary for fall-only users.

#2 · Fastest Listed Kill

2. BioAdvanced 24-Hour Grub Plus

• Weight: 20 lb
• Form: Granules

Best for: Fast-response lawn treatment.

Why it ranks #2: The supplied facts say it kills listed grubs within 24 hours and recommend applying at the first sign of an infestation.

Grubs are listed to be killed within 24 hours, making BioAdvanced 24-Hour Grub Plus a fit for homeowners responding to an observed infestation. Its ready-to-spread granules treat up to 10,000 square feet and also target listed lawn insects such as ticks, billbugs, and chinch bugs.

The 24-hour grub-kill claim suits a response at the first sign of an infestation, and the directions specify watering granules in thoroughly to kill by contact. Treating up to 10,000 square feet gives a stated coverage limit for planning a lawn application. The pest list also includes ticks, billbugs, chinch bugs, cutworms, earwigs, and grasshoppers. It is a contact-focused choice for pests that are present, rather than a claim of season-long protection.

Skip it if you want a one-application season-long protective zone; BioAdvanced Season Long Grub Control is listed for that use.

Pick this for a lawn with listed pests already present when quick grub control and stated coverage matter. It suits buyers prepared to water the granules in; it is not the listed choice for season-long protection from one application.

#3 · Season-Long Granules

3. BioAdvanced Season Long

• Weight: 10 lb
• Form: Granules

Best for: Season-long lawn barrier.

Why it ranks #3: One application creates a season-long protective zone and controls grubs plus more than 40 listed lawn insects, though fall timing is not specified.

One application creates a season-long protective zone, giving homeowners a single-treatment approach to listed lawn pests above and below the surface. BioAdvanced’s granules target grubs before they damage turf and also cover more than 40 other listed lawn insects, including ticks, ants, and mole crickets.

The granule form suits a lawn-wide application, while the listed above- and below-surface activity addresses pests in different parts of the lawn. Season-long control from one application can reduce repeat-treatment steps during the season. Coverage extends to more than 40 listed lawn insects, including chinch bugs, billbugs, ticks, and mole crickets, so this is broader than a grub-only option. The 10-pound bag is the supplied package size; the product is listed for all lawn types.

Skip it if you need a stated square-foot coverage figure; BioAdvanced 24-Hour Grub Plus lists treatment for up to 10,000 square feet.

Choose it if you want granules for a one-application, season-long lawn treatment that also targets listed insects beyond grubs. Its fit is strongest when broad listed pest coverage matters more than a specified coverage-area figure.

#4 · Longest Listed Duration

4. Atticus Asenra SRX

• Weight: 1.28 oz
• Form: Liquid

Best for: Extended turf and landscape control.

Why it ranks #4: Its 18.4% chlorantraniliprole formula is described as providing above- and below-ground control for up to 120 days.

Up to 120 days of above- and below-ground pest control is the central draw of Atticus Asenra SRX, which contains 18.4% chlorantraniliprole. Its listed targets include root-feeding white grubs and above-ground pests such as billbugs and caterpillars, linking turf treatment with protection for landscape ornamentals.

The up-to-120-day control period can suit buyers seeking coverage that extends beyond a short-contact treatment, while the above- and below-ground activity addresses different pest locations. The listed targets include white grub species such as Japanese beetle and black turfgrass Ataenius, plus billbugs and caterpillars. Atticus also describes lawn-to-landscape protection and confirms use against leaf-eating insects on ornamentals. The product is a liquid in a four-ounce bottle, and the complete control list is directed to the label.

Skip it if you need a stated lawn coverage area; BioAdvanced 24-Hour Grub Plus lists treatment for up to 10,000 square feet.

This fits buyers seeking extended turf control that also addresses listed landscape pests. Consider it when its liquid format and label-based application suit your workflow; the supplied information does not provide a coverage-area figure.

#5

5. Bonide Grub Beater

• Weight: 0.27 g
• Form: Granules

Best for: Late-spring lawn application.

Why it ranks #5: It offers season-long control for nearly all turf-damaging grub species, but its stated best application window ends in mid-August.

A stated 5,000-square-foot coverage area gives Bonide Annual Insect Control a clear planning limit for treating turf. Its directions identify late May through mid-August as the application window for best results, so this granule-based, season-long grub treatment is better matched to that schedule than a fall-only application.

The six-pound granule product covers up to 5,000 square feet, helping buyers compare the treatment area with the lawn before applying. Bonide says it controls nearly all turf-damaging grub species and provides season-long control, with systemic action lasting through the season. The stated late-May-to-mid-August timing is central to its use: buyers seeking fall application should account for that recommended window. Its claim that feeding stops immediately and grubs die quickly adds a response benefit within that seasonal plan.

Skip it if you need a product expressly suited to fall application; St. Gabriel Organics Milky Spore directions include fall treatments.

Choose this for a lawn within the stated coverage area when you can apply during its late-spring-to-mid-summer window. It offers season-long control, but its specified timing is an important fit consideration for fall roundup shoppers.

6. Hi-Yield Grub Free Zone III

• Form: Granules

Best for: Lawn and flower-bed coverage.

Why it ranks #6: It treats up to 7,000 square feet and controls listed white grubs, but the supplied application guidance focuses on spring through summer.

One 10-pound bag treats up to 7,000 square feet of lawn or flower beds, giving Hi-Yield Grub Free Zone III a defined role across turf and planted areas. Its granules can also be used on ground covers and around ornamental trees, extending the listed use beyond the lawn.

The stated 7,000-square-foot coverage helps size a treatment for lawns or flower beds, while the label also lists ground covers and application around ornamental trees. That range can simplify choosing one product for several landscape areas. Hi-Yield describes season-long killing and repelling of grubs and other insects, with application possible from spring through summer. The pest list includes larvae of Japanese beetle, Oriental beetle, chafers, Asiatic garden beetle, May or June beetles, and black turfgrass Ataenius.

Skip it if you require fall-season application directions; St. Gabriel Organics Milky Spore specifies spring, summer, and fall treatments.

Choose it for a spring-through-summer application spanning lawn, flower beds, or other listed landscape areas. Its broad placement options suit mixed yards, but the stated application window does not extend into fall.

#7

7. Southern Ag Grubs Away

• Weight: 4.08 kg

Best for: Turf and landscape plant coverage.

Why it ranks #7: The 9-pound bag treats up to 6,400 square feet, but its directions emphasize applying before target-pest egg hatch rather than fall timing.

Coverage of up to 6,400 square feet pairs with listed use on turfgrasses and landscape plants, making Southern Ag Grubs Away a granular option for mixed outdoor areas. Its 0.5% imidacloprid formula controls grubs, mole crickets, and listed insect larvae, while chinch bugs are listed as suppressed.

The coverage figure provides a useful area limit for planning, and the listed turfgrass and landscape-plant uses allow treatment across more than lawn alone. Southern Ag names grubs, billbugs, European crane fly, annual bluegrass weevil, and mole crickets among controlled pests. Chinch bug suppression has a specific timing condition: application before the first instar nymphs hatch. The supplied rate is 1.4 to 1.8 pounds per 1,000 square feet, so the coverage claim should be considered alongside the label’s rate and application directions.

Skip it if you want a 24-hour grub-kill claim; BioAdvanced 24-Hour Grub Plus lists grub control within 24 hours.

This suits buyers treating turf and landscape plants who can plan around pest timing and follow the stated rate. It lists several lawn pests, but chinch bug suppression depends on applying before hatch.

#8

8. Liquid Harvest Pro Grub Control

• Form: Liquid

Best for: Turf and landscape concentrate.

Why it ranks #8: This 21.4% imidacloprid concentrate can be applied to turf, but its broad uses and variable rates require careful label matching.

A 21.4% imidacloprid concentrate can be applied to turf, as a foliar spray, or to soil, giving buyers several treatment routes across lawns and landscape plants. Liquid Harvest Pro Grub Control also lists trees, shrubs, ornamentals, fruit and nut trees, and interior plantscapes among its uses.

The concentrate’s application options let users match treatment to the target: turfgrass, foliage, or soil around plants. Turfgrass rates are supplied per 1,000 square feet, while foliar and soil rates use different measures, so application requires following the relevant label directions rather than assuming one mix rate fits every job. Its listed use across turf and ornamentals can suit mixed landscapes, but the safety information calls for protective clothing and gloves and warns of possible harm to bees and other beneficial insects.

Skip it if you want ready-to-spread lawn granules; Hi-Yield Grub Free Zone III lists granules for lawns and flower beds.

Consider it if you need a concentrate for turf plus landscape plants and can follow distinct application rates and safety precautions. Its multiple treatment routes suit varied plantings, but require careful handling around beneficial insects.

#9

9. Bonide Insect and Grub Control

• Weight: 6 lb
• Form: Granules

Best for: Lawn and foundation pest control.

Why it ranks #9: The granules target grubs and other listed insects, but the supplied description says to apply anytime from spring through summer.

Bonide Insect and Grub Control covers listed pests both above and below ground, with outdoor use on lawns and around a home’s foundation. Its granules target grubs alongside ants, crickets, chinch bugs, billbugs, cutworms, earwigs, fleas, roaches, sod webworms, and ticks.

The lawn-and-foundation use combines turf treatment with an outdoor perimeter application, which can suit buyers addressing listed pests in both places. The product is described as fast-acting and long-lasting, and its annual application is listed for spring through summer. Its pest range includes grubs as well as surface pests such as ticks, fleas, and roaches. The directions explicitly limit use to outdoors, so this is not an indoor treatment even when a listed pest is also encountered inside.

Skip it if you need indoor pest treatment; BioAdvanced 24-Hour Grub Plus is also listed for outdoor use, so neither suits that need.

Pick it if your target areas are the lawn and outdoor foundation perimeter and the listed pests match your needs. The outdoor-only restriction is decisive: it does not provide indoor treatment.

#10

10. Southern Ag Grubs Away 0.5G

• Weight: 0.27 g
• Form: Capsules

Best for: Defined-area grub and mole cricket control.

Why it ranks #10: It controls grubs and mole crickets and treats up to 6,400 square feet, but the supplied information gives no fall-specific directions.

A stated treatment area of up to 6,400 square feet gives Southern Ag Grubs Away a clear coverage limit for lawn planning. Its systemic imidacloprid formula targets grubs and mole crickets, making it a focused choice for buyers whose priority is those two listed pests.

The systemic action distinguishes this product’s approach from a treatment described only as contact-kill, while the stated coverage of up to 6,400 square feet helps size a lawn application. The listed target pests are grubs and mole crickets, so its supplied claims are narrower than products naming many additional insects. Its 0.5G designation appears in the title, and the specifications list an item form of capsules; buyers should use the supplied label directions for application details.

Skip it if you need control of ticks and billbugs too; Southern Ag Grubs Away Systemic Insect Control lists both among its targets.

This fits buyers seeking systemic treatment for grubs and mole crickets across a stated lawn area. Its listed pest scope is focused, so choose it when those targets—not a wider insect list—match the job.
