6 Best Pest Control For Grasshoppers | No More Chewed-Up Leaves

A granular bait built for the lawn, taking out grasshoppers and crickets right where they breed.

If your grasshopper problem is really a lawn problem — with young nymphs hopping through the turf — this bait is purpose-built for that scene. At 5% carbaryl, it controls mole crickets, cutworms, armyworms, field crickets, sowbugs, and grasshoppers, and it is labeled for lawns, ornamentals, vegetables, and other crops. Unlike a spray that coats leaves, a bait gets eaten by the pests as they forage, which is why it shines on the ground level.

The evidence for that approach is direct: one owner had mole crickets all over the lawn edge and, after two applications over 3 months, reported they are now gone. Another notes there were much fewer little black young lubbers in the yard after spreading — exactly the stage of grasshopper life that destroys grass roots. The advice to wear gloves and a mask comes straight from the review pages, so treat this as standard practice with any granule.

It is a heavier bag than the Acephate at 3 pounds versus 1 pound, giving you more coverage for the same type of effort, and it is frequently described as hard to find — a sign that people who rely on it stock up. The trade-off is that it is a bait, not a contact spray, so it works by consumption rather than instant knockdown; give it a day or two to move through the population.

The non-toxic dust that dries out insects on contact — safe enough for the house, the dog, and the garden.

Diatomaceous earth is a different weapon entirely: it is a fine powder made of fossilized remains that works by deteriorating an insect’s feet, legs, and body on contact, with insects dying within 48 hours. Because the action is physical rather than chemical, insects cannot become immune to it, and it is safe to apply over the top while animals are present, on crops, and on stored grain — the reason it earns a USDA specification and a strong following among pet owners.

What wins people over here is the safety and value. The thing everyone raves about is that you can sprinkle it on carpets, beds, or lightly on a dog to handle fleas, leave it for days, vacuum, and repeat. One buyer called it cheaper than an exterminator and noted the same bag lasted 3 years, which is remarkable endurance for a 5-pound purchase compared to the 2.38-pound garlic spray above.

The honest caveat is that effectiveness gets mixed feedback depending on the pest and conditions — it works best as a dry dust in protected areas, and one owner noted it must be reapplied after every good rain. In a wet garden it will not hold up like a chemical barrier, so treat it as the gentle, persistent option rather than the instant cure.

A garlic barrier you spray on with the hose — no mixing, no measuring, and safe on the vegetables you eat.

This is the gentlest entry on the list and the only one built around repellence rather than killing. Made from pure garlic extract and OMRI listed for organic gardening, it creates an invisible sulfur barrier that repels aphids, mites, mealybugs, whiteflies, beetles, caterpillars, grubs, thrips, borers, scale, grasshoppers, crickets, mosquitos, gnats, ticks, and fleas. Because it is safe to apply directly on vegetables, fruits, herbs, flowers, shrubs, and trees, it is the obvious pick for a kitchen garden.

The convenience is the standout feature: the concentrate mixes with water at the perfect ratio as you spray, so you attach it to the hose, spray what you need, and store the rest — no mixing, no wasted batch. One long-time garlic-user called it the best and easiest way to go, while another confirmed the bigger bugs stay away when sprayed every two weeks, with the on/off switch making the job simple.

The blunt truth from the reviews is that the smell is very strong initially — it even lingers on the Amazon box — though it dries odorless and dissipates in about 30 minutes, and it will not affect the taste of treated produce. There is also an occasional report of the spray nozzle clogging right away, which is the one mechanical risk in an otherwise simple to use design.

The same active ingredient pros have trusted for decades, in a liquid that mixes clean with no dusty residue.

This is the professional-grade option, packing 11.8% beta-cyfluthrin — the same active ingredient as the leading brand — into a liquid suspension concentrate that tackles more than 100 nuisance pests indoors or out. Owners mention it is effective against grasshoppers, fleas, spiders, and bees, and the thing everyone raves about is the effectiveness, with one buyer noting they have used it for 20 years and always come back to this chemistry.

The liquid format is the practical advantage over granules: it stays in suspension and mixes easily with agitation, and it delivers a lasting residual to keep pests in check after application. One owner sprayed the entire perimeter of a 3000 sq ft home with a 2 gallon mixture ratio and reported no real odor, while another used it in a restaurant for years and now at home with cats, noting the same cost as one visit from a professional with the same results. Pets and people can re-enter once the spray has dried.

Compared to the Acephate above, this trades granular convenience for a cleaner liquid you dilute yourself, and it skips the pungent chemical smell entirely. The recurring gripe is value — some call it a bit pricey for the 240ml size even as they praise the performance, so think of it as a precision tool for perimeter and targeted spraying rather than a whole-yard drench.

A hose-ready bifenthrin spray that wipes out heavy grasshopper pressure across thousands of square feet.

When the grasshopper population has exploded and you need to reclaim a large yard fast, this 32oz ready-to-spray bottle is built for that scale. The active ingredient is bifenthrin at 2.4%, and the label claims a single bottle can treat up to 10,600 sq ft of lawn — far more than any concentrate on this list can stretch. It is virtually odor-free and water-based, so it will not leave stains on treated areas.

The owner reports here are striking in their consistency. One buyer with a half-acre yard infested with baby grasshoppers used two bottles, targeted the nesting spots, and woke to a clear yard the next day. Another sprayed roughly 3,000 sq ft with half a bottle and watched 90% of the grasshoppers die within 2 hours, with nearly all dead by the next morning. A third eliminated hundreds with a single spray, including on rose bushes, with no plant damage.

That puts it ahead of the Acephate for pure grasshopper-killing speed on open ground, though it is a one-trick spray rather than a 125-pest arsenal. A practical note from reviewers: you will likely have leftover product — one owner had 3/4 of the bottle unused — so it is generous coverage for the price. The only hesitation voiced is that it feels a bit toxic to inhale for sensitive people, so spraying upwind and letting it dry before re-entry is the smart play.
