Best Grasshopper Killer For Lawns: Compare 10 Options

#1 · Best Overall

1. BioAdvanced 24-Hour Grub Plus

• Form: Granules
• Weight: 20 lb

Best for: Grasshopper-listed lawn granules.

Why it ranks #1: Grasshoppers are explicitly listed among its lawn pests; the 20-pound ready-to-spread granules cover up to 10,000 square feet.

Grasshoppers are explicitly included among the listed pests killed by BioAdvanced 24-Hour Grub Plus, making its target list especially relevant to this roundup. The ready-to-spread granules treat up to 10,000 square feet, and the product states that it kills grubs within 24 hours when used at the first sign of an infestation.

The granular format suits lawn treatment across a stated area of up to 10,000 square feet, while the 24-hour grub claim gives buyers a defined expectation for its named grub target. Grasshoppers, ticks, billbugs, chinch bugs, crickets, cutworms, and earwigs are also listed. The supplied directions call for applying granules only when grubs or other listed pests are present and watering them in thoroughly, connecting application timing and watering to the product’s contact action.

Skip it if you want a ready-to-spray application instead of granules; Spectracide Triazicide connects to a hose end and lists grasshopper-free broad insect targets.

This is a direct fit when grasshoppers or grubs are among the lawn pests you need to address and a granular, watered-in application suits your routine. Follow the label’s pest-specific directions.

#2 · Broad Coverage Spray

2. Spectracide Triazicide

• Form: Spray
• Weight: 2.4 lb

Best for: Hose-end lawn and landscape coverage.

Why it ranks #2: A lawn-and-landscape concentrate kills 260-plus listed insects by contact and the ready-to-spray 32-ounce version can treat up to 16,000 square feet.

A hose-end, ready-to-spray format lets you apply Spectracide Triazicide across lawn and landscape areas without first mixing a concentrate. The listing says one 32-ounce bottle can treat up to 16,000 square feet, while its contact formula targets more than 260 listed insects, including grubs, fleas, ticks, and Japanese beetles.

The hose-end application connects the bottle to a garden hose, making it a practical fit for treating turf and other listed outdoor areas in one workflow. Its stated coverage of up to 16,000 square feet helps buyers estimate whether a bottle suits their lawn. The formula is listed for use on lawns, vegetables, fruit and nut trees, flowers, shrubs, and trees, so it can cover several parts of a landscape. The label cautions that siding results depend on age and cleanliness.

Skip it if you need a granular treatment or a product specifically listing grasshoppers; BioAdvanced 24-Hour Grub Plus names grasshoppers among its targets.

This suits lawn owners who want hose-end application across turf and multiple landscape plantings, with broad listed insect coverage. Check the label for use directions and the siding caveat if spraying near exterior walls.

#3 · Residual Lawn Granules

3. Ortho BugClear Lawn Insect Killer

• Form: Granules
• Weight: 16 oz

Best for: Longer residual lawn protection.

Why it ranks #3: Its 20-pound lawn granules provide three months of residual protection against other listed pests, though the supplied list does not name grasshoppers.

Up to six months of control for certain ants is the defining feature of Ortho BugClear Lawn Insect Killer1, giving buyers a granular option when extended ant control matters. Its listing also states three months of residual protection against other listed pests and says the product starts working in minutes, except against fire ants.

The granules suit buyers who prefer a spreadable lawn treatment over a hose-end spray, and the listed fast start means control begins in minutes for covered pests other than fire ants. The longer residual claim is specific: up to six months for ants, excluding pharaoh, carpenter, and harvester ants, and three months for other listed pests. The product is also listed for ornamental plants, a home perimeter, flower beds, and listed vegetable plants, extending its stated use beyond turf.

Skip it if you need grasshoppers explicitly named on the target list; BioAdvanced 24-Hour Grub Plus lists them among its lawn pests.

Choose this for a granular lawn treatment when residual ant control is a priority and the excluded ant species are not your target. Its listed protection periods vary by pest, so match the target to the label.

#4 · Above-Below Control

4. The Andersons DuoCide

• Form: Granule

Best for: Water-in granules for soil pests.

Why it ranks #4: Professional-grade granules target more than 50 common lawn pests above and below the lawn surface; grasshoppers are not named in the supplied list.

DuoCide’s DG granules disperse quickly and completely when watered, moving the pesticides into the soil for buyers targeting pests both above and below a lawn’s surface. The listing identifies more than 50 common lawn pests, including grubs, ticks, fire ants, mole crickets, and fleas, and describes a single application as a double kill.

The water-in DG formulation links application to a clear lawn-care step: water after spreading so the granules disperse and move into soil. That supports treatment aimed at both surface and soil-level pests, rather than only one zone. Its combination of bifenthrin and carbaryl is described as professional-grade, and the product is listed to cover up to 9,000 square feet. The safety information says not to apply if rain is expected within 24 hours and to keep the container closed when not in use.

Skip it if you live in California or need a spray-ready product; Spectracide Triazicide is listed as a hose-end ready-to-spray option.

This fits lawn owners seeking granular coverage for a broad range of surface and soil pests who can water the treatment in. Avoid it if rain is expected within 24 hours or if you are in California.

#5

5. Sevin Insect Killer Granules II

• Form: Granules
• Weight: 10 lb

Best for: Lawn and edible garden granules.

Why it ranks #5: These 10-pound granules work above and below the surface and kill over 100 listed insects by contact, but grasshoppers are not specified.

Sevin Insect Killer Granules II is listed for lawns, fruits, and vegetables, giving buyers one granular product for turf and edible garden areas. It kills more than 100 listed insects by contact above and below the surface, and the supplied details state that its protection lasts three months for ants, ticks, and other garden insects.

The granular form can be spread over a lawn or affected area, and the supplied directions specify using a broadcast spreader. That makes it a fit for buyers already equipped to distribute granules across outdoor spaces. Its listed use on lawns, fruits, and vegetables extends the treatment area beyond turf, while above- and below-surface contact action addresses pests in both zones. The three-month duration is stated for ants, ticks, and other garden insects; apply early or at the first signs of insect activity.

Skip it if you lack a broadcast spreader and want hose-end application; Spectracide Triazicide is a ready-to-spray hose-end alternative.

Choose this if you want granular coverage across lawn and edible garden areas and can apply with a broadcast spreader. Its listed three-month protection applies to garden insects including ants and ticks.

6. Sevin Lawn Insect Granules

• Form: Granules
• Weight: 0.27 g

Best for: Broad-use granules for larger properties.

Why it ranks #6: The lawn granules kill over 30 listed pests and can be spread across large areas, but the provided pest examples do not include grasshoppers.

Use across lawns, ornamentals, around homes, and vegetables gives Gardentech Sevin Lawn Insect Granules a broad range of listed outdoor settings. The granules target more than 30 listed pests, including ticks, fleas, worms, and ants, and the supplied description identifies spreader application for coverage across larger areas or property perimeters.

The granular form supports spreader application across lawn areas, flowerbeds, ornamentals, and soil areas, giving buyers several ways to use it around a property. Its stated target list includes more than 30 pests, with ticks, fleas, worms, and ants specifically named. The supplied description says to water thoroughly after spreading, so application involves both distributing granules and watering them in. This is a useful workflow for broader outdoor treatment, but the listing does not give a specific square-foot coverage figure.

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

This suits property owners treating lawns and several other outdoor areas who can spread and water in granules. Consider another listing if you need a stated coverage figure or grasshoppers named specifically.

7. Amdro Quick Kill

• Form: Spray
• Weight: 2.2 lb

Best for: Ready-to-spray broad insect coverage.

Why it ranks #7: This 32-ounce ready-to-spray lawn and landscape product targets over 500 listed insects and offers up to three months of control, without naming grasshoppers.

A ready-to-spray format and a target list of more than 500 insects make Amdro Quick Kill a convenient option for buyers seeking broad lawn and landscape coverage. Its listing says the contact-kill spray protects lawns, flowers, trees, and shrubs and provides up to three months of insect control.

The ready-to-spray bottle is presented as a quick, straightforward application: check for listed pests and use the product on the lawn or landscape. Its stated coverage includes flowers, trees, and shrubs as well as turf, letting buyers address several outdoor planting areas with one product. The target list includes ants, spiders, fleas, Japanese beetles, chinch bugs, mosquitoes, and more. Up to three months of control is the listed duration, while the formula kills insects by contact.

Skip it if you need a specified square-foot coverage amount before spraying; BioAdvanced Complete Brand lists coverage up to 5,333 square feet.

This is a fit for buyers wanting ready-to-spray coverage across turf and landscape plants with a broad listed insect target range. Check the product label for application directions and area coverage.

#8

8. BioAdvanced Complete Insect Killer

• Form: Spray
• Weight: 16 oz

Best for: Measured coverage for surface pests.

Why it ranks #8: Its 32-ounce ready-to-spray bottle treats up to 5,333 square feet and targets over 500 listed pests, but grasshoppers are not identified.

The ready-to-spray bottle treats up to 5,333 square feet, giving BioAdvanced Complete Brand buyers a defined area for planning lawn application. Its two-way formula controls surface insects, kills listed pests including grubs, ants, and ticks, and provides up to two weeks of protection against listed surface insects.

The ready-to-spray format avoids a separate mixing step, while the stated 5,333-square-foot coverage helps buyers judge whether the bottle matches their treatment area. Its two-way formula is described as controlling surface insects, with contact killing for listed pests including grubs, ants, and ticks. The target list also includes mosquitoes and more than 500 other listed outdoor pests. Protection is stated to last up to two weeks, a useful boundary for planning follow-up rather than assuming longer residual control.

Skip it if you need grasshoppers explicitly listed or longer residual protection; BioAdvanced 24-Hour Grub Plus names grasshoppers and covers up to 10,000 square feet.

This fits buyers who want a ready-to-spray treatment with a stated area and short, defined residual period for listed surface insects. Check the label to confirm the target pest and application directions.

#9

9. Spectracide Immunox Fungus Plus

• Form: Spray
• Weight: 2.4 lb

Best for: Combined lawn fungus and insect control.

Why it ranks #9: This hose-end lawn spray combines insect control with listed lawn disease control, but the supplied details do not identify grasshoppers as a target.

A dual-action formula that controls listed lawn diseases and fungus while killing listed lawn-damaging insects gives Spectracide Immunox two lawn-care roles in one spray. Its QuickFlip hose-end sprayer attaches to a garden hose and activates at a switch, while the listing says the treatment becomes rainproof in hours.

The QuickFlip sprayer connects directly to a hose, simplifying application for buyers who want a ready-to-spray lawn product rather than a separate mixing step. The dual-action claim combines control of listed diseases and fungus with contact killing of listed lawn-damaging insects, so it addresses more than insect pressure. The listing recommends starting when grass begins to green in spring and treating every two weeks for best results. Rainproofing in hours can help the applied product withstand rain after that period.

Skip it if you want a product specifically naming grasshoppers or a single treatment without a stated two-week schedule; BioAdvanced 24-Hour Grub Plus lists grasshoppers.

This suits lawn owners addressing listed fungus or disease alongside insect concerns who are comfortable with hose-end spraying and a repeating schedule. Its insect claim is general, so check the label for your target pest.

#10

10. Agrisel Bifenthrin Pro 7.9

• Form: Liquid
• Weight: 9.2 lb

Best for: Concentrate for varied outdoor settings.

Why it ranks #10: Its broad-spectrum liquid is described for lawn and ornamental settings, but the supplied information does not name grasshoppers or give lawn coverage.

Agrisel Bifenthrin Pro 7.9 lists use across lawn care, ornamental areas, and agricultural settings, offering buyers a liquid insecticide for more than one outdoor context. Its broad target list includes spiders, ants, fleas, mole crickets, and stink bugs, while the supplied details state pets are safe around the area 1–2 hours after application has dried.

The liquid formula is listed for multiple environments, including lawns and ornamental settings, so it can suit buyers managing varied outdoor areas. The target list names common insects such as spiders, ants, fleas, mole crickets, and stink bugs. Supplied application facts also describe spraying trails, entry points, and nests, with nests targeted in the evening when insects are inactive. The pet-safety statement is conditional: pets are safe after the application has dried for 1–2 hours, so that drying interval matters to household routines.

Skip it if you need a ready-to-spray bottle with a stated lawn coverage figure; BioAdvanced Complete Brand treats up to 5,333 square feet.

This may suit buyers treating varied outdoor settings who can manage the stated drying interval before pets return. Its supplied facts do not give a lawn coverage figure or explicitly name grasshoppers.
