Best Grub Worm Killer For Lawns: 10 Options Compared

#1 · Best Overall

1. BioAdvanced Season Long Granules

• Weight: 10 lb
• Form: Granules

Best for: Season-long lawn protection.

Why it ranks #1: One application is stated to protect all season; the granules target grubs above and below the surface and more than 13 listed grub species.

One application creates a season-long protective zone, giving lawn owners a single-treatment approach to listed grubs and other damaging insects. BioAdvanced’s granules target pests above and below the surface, and the listed control includes more than 13 grub types as well as ants, ticks, and chinch bugs.

The 10-pound granule bag combines season-long control with a broad listed pest range, making it a fit for buyers addressing grubs alongside insects such as mole crickets, ticks, and chinch bugs. Because the product is stated to work above and below the surface, one application can protect turf against pests in both locations. It is listed for all lawn types, so the stated use is not limited to a particular kind of grass. Apply only according to the product label.

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 this for a lawn where a single seasonal application and control of several listed insect types are priorities. Its stated fit spans all lawn types, but the supplied product details do not give a coverage-area figure.

#2 · Fastest Stated Action

2. BioAdvanced 24-Hour Grub Plus

• Weight: 20 lb
• Form: Granules

Best for: Fast-response grub treatment.

Why it ranks #2: The listing says it kills grubs within 24 hours, treats up to 10,000 square feet, and targets several other listed lawn pests.

Grubs are killed within 24 hours, giving this ready-to-spread BioAdvanced formula a clear role when an infestation is already showing. The 20-pound bag treats up to 10,000 square feet and also targets listed pests including ticks, billbugs, chinch bugs, crickets, and cutworms.

Use this granule treatment at the first sign of grubs or other listed pests, then water it in thoroughly; the supplied directions connect watering with contact kill. The 24-hour grub action suits buyers seeking a quick response rather than a season-long prevention claim. Its stated coverage of up to 10,000 square feet helps with planning a lawn treatment, while the broad insect list may address several concurrent lawn pests in one application. Carpenter, fire, harvester, and pharaoh ants are excluded.

Skip it if you want season-long protection from one application; BioAdvanced Season Long Grub Control is specifically listed for that use.

This suits lawn owners responding to visible grub activity who want stated 24-hour control and coverage up to 10,000 square feet. It is intended for pests that are present, and the listed ant exclusions matter.

#3 · Broad Landscape Use

3. Hi-Yield Grub Free Zone II

• Weight: 15 lb
• Form: Granules

Best for: Lawn and flower-bed treatment.

Why it ranks #3: It is listed for lawns, ground covers, flower beds, and ornamental tree bases, with a 15-pound bag treating up to 5,000 square feet.

A 15-pound bag treats up to 5,000 square feet, giving Hi-Yield Grub Free Zone II a defined coverage area for lawns or flower beds. Its seasonal grub and insect control also extends to ground covers and around ornamental tree bases, with application allowed from spring through summer.

The granules offer a useful combination of measured lawn or flower-bed coverage and several listed landscape locations. Buyers can apply the product to lawns, ground covers, flower beds, and around ornamental tree bases, rather than limiting the treatment to turf. The supplied information says to apply from spring through summer and notes that best results come from application before grubs hatch. Specific directions also describe applying around roses and shrubs, making the label relevant when treating those plantings.

Skip it if you need coverage beyond 5,000 square feet from one bag; BioAdvanced 24-Hour Grub Plus lists treatment for up to 10,000 square feet.

This is a fit for buyers treating a defined lawn or flower-bed area while also addressing ground covers or ornamental tree bases. Its listed coverage is up to 5,000 square feet, and timing before grub hatch is advised.

#4 · Season-Long Coverage

4. Bonide Annual Grub Beater

• Weight: 0.27 g
• Form: Granules

Best for: Season-long systemic granules.

Why it ranks #4: This annual grub treatment covers up to 5,000 square feet and is directed for application from late May through mid-August.

Bonide’s stated late-May-through-mid-August application window gives this six-pound annual grub treatment a clear seasonal schedule. The granules cover up to 5,000 square feet and provide season-long control for nearly all turf-damaging grub species, with feeding activity said to stop immediately.

The stated coverage of up to 5,000 square feet helps buyers estimate how much lawn an individual six-pound bag can treat. Apply granules to soil during the listed late-May-through-mid-August window for best results; the supplied information describes the resulting control as season-long. The product is specifically presented for nearly all turf-damaging grub species, making it a focused option for grub control rather than a claim of broad control over many named insect types. Follow local regulations and application directions.

Skip it if you need control of named non-grub pests too; Bonide Insect and Grub Control lists ticks, fleas, cutworms, and other insects.

Choose this for a lawn-focused annual grub application when the stated seasonal timing and 5,000-square-foot coverage suit your plan. Its supplied claims emphasize grub species, not a long list of other named lawn insects.

#5 · Largest Stated Coverage

5. Southern Ag Grubs Away

• Weight: 4.08 kg

Best for: Landscape and turf coverage.

Why it ranks #5: The 9-pound systemic granule product treats up to 6,400 square feet and lists grubs, billbugs, crane flies, and mole crickets as targets.

Southern Ag Grubs Away treats up to 6,400 square feet, providing a defined coverage target for buyers treating turf or landscape plants. Its granules contain 0.5% imidacloprid and control listed grubs, mole crickets, and insect larvae, while also suppressing chinch bugs when applied at the stated timing.

The product’s coverage figure and application rate—1.4 to 1.8 pounds per 1,000 square feet—help buyers plan granule use across a lawn or landscape planting. Apply before egg hatch of the target pest, then provide sufficient irrigation, as directed in the supplied description. The listed control includes grubs, billbugs, European crane fly, annual bluegrass weevil, and mole crickets; chinch bugs are described as suppressed when treatment precedes hatching of first-instar nymphs. Timing is therefore an important part of fit.

Skip it if you need stated 24-hour grub kill; BioAdvanced 24-Hour Grub Plus specifies that result.

This fits buyers treating turf or landscape plants who can time application before target-pest egg hatch and follow the stated rate. Chinch bug suppression has a specific timing condition, unlike its listed grub control.

#6

6. Atticus Asenra SRX

• Weight: 1.28 oz
• Form: Liquid

Best for: Extended turf and landscape control.

Why it ranks #6: Its 18.4% chlorantraniliprole formula is stated to provide control for up to 120 days against white grubs and several other turf pests.

Up to 120 days of control is the defining feature of Atticus Asenra SRX, enabling extended treatment of turf pests with a liquid containing 18.4% chlorantraniliprole. Its listed targets include root-feeding white grubs and above-ground pests such as billbugs and caterpillars, with landscape ornamentals also included in its protection claims.

The liquid formulation combines above- and below-ground pest control with a stated duration of up to 120 days, which may suit buyers managing turf pests across a longer treatment window. Its listed white grub targets include Japanese beetle and black turfgrass Ataenius, while billbugs and caterpillars extend the control list above ground. The product also states that it kills leaf-eating insects to safeguard landscape ornamentals. The supplied details direct buyers to the label for the complete control list.

Skip it if you need a stated lawn coverage area; Southern Ag Grubs Away lists treatment for up to 6,400 square feet.

Consider this liquid for buyers treating turf and landscape ornamentals who value a stated control period of up to 120 days. Check its label for the full pest list and application details before choosing it.

#7

7. Andersons DuoCide

• Form: Granule

Best for: Broad-spectrum soil granules.

Why it ranks #7: This lawn granule lists more than 50 common pests, including grubs, and its DG granules disperse when watered to move pesticides into soil.

DuoCide’s DG granules disperse quickly and completely when watered, moving pesticides directly into the soil for a stated double-kill effect above and below the lawn surface. The formula combines bifenthrin and carbaryl and lists more than 50 common lawn pests, including grubs, ticks, fire ants, fleas, and mole crickets.

The granular format and watering-activated dispersal connect application to soil delivery, a useful feature when targeting grubs alongside above-ground lawn pests. The product claims a single application can eliminate pests both above and below the surface, while its more-than-50-pest list includes several common lawn insects. Its stated coverage is up to 9,000 square feet, helping buyers gauge area, and the listed formula contains two professional-grade insecticides. It is not for sale in California, and the supplied safety information warns against application if rain is expected within 24 hours.

Skip it if you are in California; Spectracide Triazicide is listed for lawn and landscape use without this product's California sales restriction.

This suits buyers seeking broad lawn-pest coverage in a watered-in granule treatment, with stated coverage up to 9,000 square feet. It is not for sale in California, and rain within 24 hours is a stated application concern.

#8

8. Bonide Insect and Grub Control

• Weight: 6 lb
• Form: Granules

Best for: Lawn and foundation perimeter.

Why it ranks #8: The 6-pound outdoor granules target grubs and numerous listed lawn insects, with application described for spring through summer.

Bonide Insect and Grub Control combines lawn treatment with outdoor use around a home’s foundation, letting buyers address listed pests in both locations with granules. The product is described as an annual application for above- and below-ground control, and its list includes grubs, ticks, fleas, cutworms, and chinch bugs.

This six-pound granule product is labeled for outdoor use on lawns and around the foundation, extending its application beyond turf while expressly excluding indoor use. The supplied description calls it an annual application and says it controls insects above and below ground, a combination relevant to buyers dealing with pests in multiple outdoor zones. Its listed targets include grubs, cranefly, ticks, fleas, cutworms, and sod webworms. The application window is anytime from spring through summer.

Skip it if you need a treatment for indoor pests; this Bonide product is expressly for outdoor use only.

This suits homeowners who want one outdoor granule product for lawn pests and the foundation perimeter. Its stated use is limited to outdoors, so it is not an option for treating insects inside the home.

#9

9. Spectracide Triazicide

• Weight: 2.4 lb
• Form: Spray

Best for: Hose-end broad insect spray.

Why it ranks #9: This ready-to-spray lawn and landscape product lists grubs among 260-plus contact-killed insects and states coverage up to 16,000 square feet.

The 32-ounce ready-to-spray Triazicide connects to a hose end, enabling lawn and landscape treatment without mixing a dilutable concentrate. Spectracide lists contact control of more than 260 insects, including grubs, ants, fleas, deer ticks, and Japanese beetles, with use across lawns and several plantings.

The ready-to-spray format makes this a practical option for buyers who want to apply a liquid through a hose-end connection rather than prepare a concentrate. The stated use extends across lawns, trees, flowers, shrubs, and vegetables, giving one product a broad outdoor role. Its contact-control list exceeds 260 insects and includes grubs, while the supplied description says the ready-to-spray product works in 24 hours and can treat up to 16,000 square feet. Siding claims depend on age and cleanliness.

Skip it if you prefer granules applied to soil; The Andersons DuoCide uses granules that disperse into soil when watered.

Choose this for buyers seeking hose-end liquid treatment across lawns and multiple landscape plantings, with stated coverage up to 16,000 square feet. Siding use has a stated qualification tied to age and cleanliness.

#10

10. St. Gabriel Milky Spore

• Weight: 2.5 lb
• Form: Granules

Best for: Japanese beetle grub control.

Why it ranks #10: Its biological approach specifically targets Japanese beetle grubs and claims years of soil activity, making it less broadly suited to unspecified grub problems.

Milky Spore’s Bacillus popilliae spores multiply and remain active in soil for years after application, making this powder a long-duration option focused on Japanese beetle grubs. One 40-ounce bag covers up to 10,000 square feet, and the product is described as safe around pets and beneficial insects.

The product’s defining biological approach is tied specifically to Japanese beetle grubs, so it fits buyers targeting that pest rather than seeking a general grub-control list. The stated persistence of spores in soil for years may reduce the need to repeat applications, although the supplied facts do not specify an exact treatment schedule. A 10,000-square-foot coverage claim gives the 40-ounce bag a broad stated area, while outdoor-only use sets a clear boundary for where it belongs.

Skip it if you need stated control of multiple grub species; BioAdvanced Season Long Grub Control lists control of more than 13 grub types.

Consider this for outdoor lawns where Japanese beetle grubs are the target and long-lasting soil activity is a priority. Its stated pest focus is narrower than a multi-species grub treatment.
