Best Grasshopper Killer for Garden: 7 Products Worth Considering

Grasshopper control products being used around a garden.

Grasshoppers can turn a healthy garden into a feeding ground surprisingly fast. A few may not seem like a big deal, but when their numbers build up, they can chew through leaves, damage tender shoots, and leave vegetable and ornamental plants looking ragged.

The tricky part is choosing the right grasshopper control product. Some treatments are designed to kill insects on contact, some work differently by affecting insects after they feed, and others are better suited to repelling or reducing pest pressure rather than providing an immediate knockdown.

That’s why we compared seven grasshopper-control products and matched each one to a particular type of gardener or control strategy.

Our lineup includes Sevin Insect Killer, Garlic Barrier AG+, Safer Brand Insecticidal Soap, Bonide Captain Jack’s Neem Oil, BotaniGard, Monterey Bug Buster-O, and Evergreen Pyrethrum Concentrate.

Whether you’re trying to protect vegetables, ornamental plants, flowers, or a larger garden area, this guide can help you compare the options before you buy.

Important: We have not personally tested these products. Our recommendations are based on product information, intended uses, active ingredients, product characteristics, and the type of grasshopper-control approach each product is designed to provide. Pesticide labels and formulations can change, so always read the current product label before purchasing or applying any treatment.

7 Best Grasshopper Killers for Gardens Compared

The best grasshopper-control product depends on what you’re trying to accomplish and where you’re applying it.

A gardener with a few grasshoppers on ornamental plants may want a very different product from someone dealing with heavy feeding throughout a vegetable garden.

Here are the seven products at a glance.

1. Best Overall Conventional Option — Sevin Insect Killer 4. 6 ☆

Sevin Insect Killer is a well-known name in garden pest control and is worth considering if you’re looking for a conventional insecticide rather than a garlic-based, soap, botanical, or biological approach.

Its biggest appeal is familiarity. Gardeners looking for a traditional insect-control product may find Sevin easier to incorporate into an existing pest-management routine.

However, Sevin is a product line rather than one single universal formulation, so don’t assume every Sevin product has identical ingredients or approved uses. Check the exact product you’re buying and confirm that grasshoppers are listed on the current label for your intended application.

Why Consider Sevin Insect Killer?

The main advantage is that it gives gardeners a conventional insecticide option when grasshoppers are causing noticeable feeding damage.

It’s particularly worth investigating when you’re dealing with an active pest problem rather than simply looking for a preventive garden strategy.

Another advantage is that Sevin products are widely recognized, making them relatively easy for gardeners to compare with other insecticides.

Pros

• Familiar garden insect-control brand
• Conventional insecticide approach
• Available in different product formats
• Useful for gardeners dealing with active insect pressure
• Easy to compare with other garden insecticides

Cons

• Different Sevin products can have different formulations
• Not every formulation should be assumed to have the same pest claims
• Requires careful label compliance
• Application restrictions may apply to edible crops
• Not necessarily the best fit for gardeners seeking a biological or low-impact approach

Best For

Gardeners who want a conventional insecticide option and whose specific Sevin product is currently labeled for grasshoppers and the intended garden application.

2. Best Garlic-Based Option — Garlic Barrier AG+ 4.1 ☆

If you would rather explore a garlic-based approach to grasshopper management, Garlic Barrier AG+ is a completely different type of product from a conventional insecticide.

Instead of approaching the problem like a traditional contact insecticide, garlic-based products appeal to gardeners who want to incorporate a strong-smelling botanical approach into their pest-management strategy.

Why Consider Garlic Barrier AG+?

The biggest attraction is its garlic-based formulation.

Some gardeners prefer trying products that fit a more natural or botanical-style garden-management philosophy, particularly when they are dealing with recurring pest pressure.

However, it’s important not to assume that a garlic-based product will perform exactly like a conventional insecticide.

If you’re dealing with a major grasshopper outbreak, read the current label carefully to understand the product’s approved uses, application directions, and whether the specific grasshopper problem you’re facing is covered.

Pros

• Garlic-based approach
• Different from conventional synthetic insecticides
• Interesting option for gardeners seeking a botanical-style strategy
• Can be incorporated into a broader pest-management program
• Useful for gardeners who want another option besides traditional insecticides

Cons

• May not be the first choice for severe infestations
• Garlic odor may not appeal to everyone
• Results can depend on pest pressure and application conditions
• Label directions must be followed carefully
• Should not automatically be considered a substitute for an insecticide

Best For

Gardeners who want to explore a garlic-based pest-management option and prefer a different approach from conventional insecticides.

3. Best Insecticidal Soap Option — Safer Brand Insecticidal Soap 4.2 ☆

Safer Brand Insecticidal Soap takes yet another approach.

Instead of relying on a conventional residual insecticide strategy, insecticidal soap works through direct contact with susceptible soft-bodied insects.

That makes application technique particularly important.

Why Consider Safer Brand Insecticidal Soap?

One of the main reasons gardeners consider insecticidal soap is that it provides an alternative to stronger conventional insecticide approaches.

It’s also a product format many gardeners are already familiar with when dealing with garden pests.

For grasshoppers, however, don’t assume that because a product is effective against some insects it will automatically provide the same level of control against every grasshopper species or life stage.

Check the current label for the exact pest and plant you’re treating.

Pros

• Soap-based insect-control approach
• Familiar option for many home gardeners
• Useful as part of an integrated pest-management strategy
• Available in convenient garden-use formulations
• Appeals to gardeners seeking an alternative to conventional insecticides

Cons

• Direct contact is important
• May require thorough coverage
• Heavy grasshopper populations can be difficult to manage with softer approaches alone
• Plant sensitivity can vary
• Label restrictions and application instructions must be followed

Best For

Gardeners looking for an insecticidal soap approach and who want to incorporate a less conventional treatment into their garden pest-management routine.

4. Best Botanical Option — Bonide Captain Jack’s Neem Oil 4.3 ☆

Bonide Captain Jack’s Neem Oil is another interesting option for gardeners who prefer a botanical approach.

Neem-based products are commonly used in garden pest management, making this product worth considering when you’re trying to build a broader strategy rather than relying exclusively on a conventional insecticide.

Why Consider Captain Jack’s Neem Oil?

The appeal here is the neem-based approach.

Rather than shopping exclusively for a traditional insect killer, gardeners can consider a product that fits into a more botanical-oriented pest-control routine.

However, neem oil isn’t a magic solution for every garden insect.

Grasshopper control can be challenging when populations are high, and the results you get can depend on the pest, plant, timing, coverage, and environmental conditions.

Pros

• Neem-based botanical approach
• Useful for gardeners who prefer botanical products
• Can fit into an integrated pest-management program
• Multi-purpose garden pest product
• Available in a familiar garden-care format

Cons

• Not necessarily the strongest choice for a major grasshopper outbreak
• Requires proper coverage and application
• Results can vary with pest pressure
• Can require repeated applications according to the label
• Always check crop and pest directions before treating edible plants

Best For

Gardeners who want a neem-based botanical product as part of a broader strategy for managing garden pests.

Check the current price and availability on Amazon

5. Best Biological Option — BotaniGard 4.1 ☆

BotaniGard stands out from the other products in this lineup because it takes a biological control approach.

Rather than relying on a conventional insecticide active ingredient, BotaniGard uses the insect-pathogenic fungus Beauveria bassiana as its active biological control agent.

That makes it especially interesting for gardeners and growers who are looking for a biological tool to add to an integrated pest-management program.

Why Consider BotaniGard?

The biggest reason to consider BotaniGard is that it’s fundamentally different from a conventional contact insecticide.

Biological products can be valuable when you’re trying to diversify your pest-management strategy and reduce dependence on one type of control method.

The tradeoff is that biological controls shouldn’t necessarily be judged by the same expectations you would have for a conventional fast-knockdown insecticide.

Environmental conditions, pest susceptibility, application timing, and thorough coverage can all matter.

Pros

• Biological control approach
• Uses Beauveria bassiana
• Different mode of action from conventional insecticides
• Interesting option for integrated pest management
• Suitable for gardeners and growers looking for a biological tool

Cons

• Doesn’t work like an instant-contact insect killer
• Performance can depend on environmental conditions
• Application timing matters
• Requires careful attention to the product label
• May not be the simplest choice for someone wanting immediate knockdown

Best For

Gardeners and growers interested in a biological pest-control approach and willing to incorporate it into a broader integrated pest-management strategy.

Check the current price and availability on Amazon

6. Best Broad Garden Option — Monterey Bug Buster-O 4.5 ☆

Monterey Bug Buster-O is another product worth comparing if you’re looking for a garden insect-control product rather than a grasshopper-only solution.

That can be useful for gardeners because grasshoppers are rarely the only insects causing problems.

A product that fits into a broader pest-management program can be more practical than buying a different bottle for every pest.

Why Consider Monterey Bug Buster-O?

The main attraction is versatility.

If your garden is experiencing several insect problems at once, a broad garden pest-control product may make more sense than purchasing multiple specialized treatments.

As always, though, check the current label for grasshoppers, the specific crop or ornamental plant, application rate, and any harvest restrictions before using it.

Pros

• Designed for garden insect control
• Useful when multiple pest problems occur
• Convenient option for gardeners wanting broader coverage
• Can fit into an integrated pest-management strategy
• Another alternative to single-purpose products

Cons

• Not every pest-control product is appropriate for every crop
• Label restrictions can vary
• Requires correct application
• Broad-use products aren’t automatically the best choice for every pest
• Check current grasshopper claims before purchasing

Best For

Gardeners looking for a broader garden insect-control option that may help simplify pest management.

Check the current price and availability on Amazon

7. Best Pyrethrum Concentrate — Evergreen Pyrethrum Concentrate 4.0 ☆

If you prefer a concentrated insecticide based on pyrethrum, Evergreen Pyrethrum Concentrate is another product worth investigating.

Concentrates can appeal to gardeners who want to mix the product according to the label rather than purchasing a ready-to-use spray.

Why Consider Evergreen Pyrethrum Concentrate?

The biggest attraction is the concentrated format combined with a pyrethrum-based insect-control approach.

Pyrethrum is derived from chrysanthemum flowers, which makes this product particularly interesting to gardeners looking for a botanical insecticide.

But botanical doesn’t mean risk-free.

Pyrethrum is still an insecticide, and it should be handled and applied with the same respect given to other pesticide products.

Pros

• Concentrated formulation
• Pyrethrum-based insect-control approach
• Botanical-origin active ingredient
• Useful for gardeners who prefer concentrates
• Can be convenient for treating according to label directions

Cons

• Requires mixing
• Concentrates require careful handling
• Application must follow the label exactly
• Not automatically suitable for every plant or crop
• Botanical insecticides can still affect beneficial insects

Best For

Gardeners who prefer a pyrethrum-based concentrate and are comfortable mixing and applying an insecticide according to the current product label.

Always confirm the current label for the specific grasshopper species, crop, application site, mixing instructions, and other restrictions.

Which Grasshopper Killer Is Right for Your Garden?

You don’t necessarily need the strongest product available.

The better approach is to match the product to the severity of the problem, the plants you’re protecting, and the type of pest-control strategy you’re comfortable using.

If you want a conventional insecticide

Start by looking at Sevin Insect Killer.

It’s the most straightforward choice in this lineup for someone specifically looking for a traditional insecticide approach.

Just make sure the exact Sevin formulation you purchase is currently labeled for grasshoppers and your intended application.

If you prefer a garlic-based approach

Garlic Barrier AG+ is the obvious product to investigate.

It’s particularly interesting for gardeners who would rather explore a garlic-based strategy instead of immediately reaching for a conventional insecticide.

If you prefer insecticidal soap

Consider Safer Brand Insecticidal Soap.

It’s a different approach from conventional insecticides and can make sense for gardeners who want a soap-based product in their pest-control toolbox.

If you prefer neem

Bonide Captain Jack’s Neem Oil is worth considering.

It’s a botanical option that can fit into a broader garden pest-management program.

If you want biological control

BotaniGard is the standout.

Its Beauveria bassiana formulation gives gardeners a fundamentally different pest-management tool.

If you want broader garden pest control

Take a closer look at Monterey Bug Buster-O.

This may make more sense when grasshoppers aren’t the only insects creating problems in your garden.

If you prefer pyrethrum

Evergreen Pyrethrum Concentrate is the product to investigate.

The concentrated format may appeal to gardeners who prefer mixing their own treatment according to the label.

How to Get Better Grasshopper Control

Buying an insecticide is only part of the solution.

Grasshoppers can be persistent, especially when surrounding areas provide plenty of vegetation and suitable habitat.

A better strategy is to combine product selection with practical garden management.

1. Start early

Don’t wait until your plants are heavily damaged before paying attention to grasshopper activity.

Finding a few grasshoppers early gives you a chance to respond before the population becomes much harder to manage.

2. Inspect the plants regularly

Look underneath leaves, around stems, and throughout areas where grasshoppers are feeding.

Freshly chewed leaves and irregular holes can be signs that something is actively feeding on the plants.

3. Remove weeds and excess vegetation

Weedy areas around gardens can provide additional food and shelter for insects.

Keeping the garden and surrounding areas managed can make the environment less attractive to pests.

4. Protect vulnerable plants

Young seedlings and tender plants can be especially vulnerable to feeding damage.

Physical barriers such as appropriate garden netting can sometimes reduce access without requiring an insecticide.

5. Don’t automatically spray everything

More pesticide isn’t necessarily better.

Identify the pest, choose a product appropriate for the crop and pest, and follow the label’s application instructions.

6. Rotate control approaches when appropriate

Repeatedly relying on the same type of insecticide can contribute to resistance problems in some pest populations.

An integrated approach can include sanitation, physical barriers, habitat management, biological controls, and properly selected insecticides.

Can You Use More Than One Grasshopper-Control Method?

Yes, but don’t mix pesticide products together unless the labels specifically allow it.

Instead, think of pest management as several complementary tools.

For example, a gardener might combine:

Garden cleanup + physical barriers + monitoring + an appropriate treatment

rather than simply spraying the entire garden repeatedly.

A biological product such as BotaniGard may also have a very different role from a conventional insecticide.

The important thing is to understand what each product is designed to do rather than assuming that combining several products will automatically produce better results.

What About Grasshopper Damage in Vegetable Gardens?

Vegetable gardens require extra care because you’re dealing with plants that may eventually be harvested and eaten.

This is one area where you should never rely on a generic statement that a product is safe for vegetables.

The exact crop, application method, treatment interval, pre-harvest interval, and other restrictions can vary.

Before treating:

1. Identify the vegetable you’re protecting.
2. Confirm that the exact product is labeled for that crop.
3. Confirm that grasshoppers are listed if required by the label.
4. Follow the application rate.
5. Observe any required harvest interval.
6. Wash produce according to appropriate food-safety practices.

The product label should always be the final authority for pesticide use.

Natural vs. Conventional Grasshopper Control

This is one of the biggest decisions gardeners face.

A product such as Garlic Barrier AG+ appeals to someone who wants a garlic-based approach.

Bonide Captain Jack’s Neem Oil offers a neem-based botanical option.

BotaniGard takes a biological route.

Evergreen Pyrethrum Concentrate provides a pyrethrum-based insecticide approach.

And products such as Sevin Insect Killer represent a more conventional insecticide strategy.

There isn’t one category that’s automatically best for every garden.

The right choice depends on the severity of the infestation, the plants you’re protecting, your pest-management preferences, and the exact product label.

10 Frequently Asked Questions About Grasshopper Control

1. What is the best grasshopper killer for a garden?

There isn’t one universal winner for every garden.

Sevin Insect Killer is worth considering if you want a conventional insecticide approach and the exact formulation is labeled for your situation. Gardeners looking for botanical or biological alternatives can compare Garlic Barrier AG+, Bonide Captain Jack’s Neem Oil, BotaniGard, or Evergreen Pyrethrum Concentrate.

Always verify the current label before applying a product.

2. What kills grasshoppers in the garden?

Several types of pest-control products can be used against grasshoppers depending on the specific product and its label.

Conventional insecticides, pyrethrum-based products, biological controls, and other garden treatments may have grasshopper claims.

The important thing is to check the exact product label rather than assuming that every garden insecticide kills grasshoppers.

3. What is the best grasshopper spray for vegetable gardens?

There isn’t one product that’s automatically best for every vegetable.

The exact vegetable, grasshopper species, product formulation, and application instructions matter.

Always choose a product whose current label specifically permits the intended use and follow any harvest restrictions.

4. Does neem oil kill grasshoppers?

Neem oil can be part of a broader garden pest-management strategy, but gardeners shouldn’t assume it will provide the same immediate results as every conventional insecticide.

If you’re considering Bonide Captain Jack’s Neem Oil, check the current label for the pest, crop, and application you’re considering.

5. Does insecticidal soap work on grasshoppers?

Insecticidal soaps are primarily known for controlling susceptible insects through direct contact.

Grasshoppers can be more challenging targets than many small soft-bodied garden pests, so don’t assume that an insecticidal soap will provide the same level of control as a product specifically intended for grasshoppers.

Check the current Safer Brand label for approved uses.

6. Is garlic effective against grasshoppers?

Garlic-based products can be used as part of some pest-management strategies, but they shouldn’t automatically be treated as equivalent to a conventional insecticide.

Garlic Barrier AG+ is worth considering if you specifically want a garlic-based approach.

7. What is the best natural grasshopper killer?

“Natural” can mean several different things.

Neem, garlic, pyrethrum, and biological products all represent different approaches, but they don’t necessarily work in the same way.

If you’re looking for a botanical or biological option, compare Garlic Barrier AG+, Bonide Captain Jack’s Neem Oil, BotaniGard, and Evergreen Pyrethrum Concentrate based on their current labels and your garden’s needs.

8. How do I stop grasshoppers from eating my plants?

Start with monitoring and garden management.

Remove excessive weeds, inspect plants regularly, consider physical barriers, and respond before grasshopper numbers become overwhelming.

When necessary, use a properly labeled treatment according to its directions.

9. Can I spray grasshopper killer directly on vegetables?

Only if the specific product label permits that crop and application.

Never assume that because a pesticide is sold for gardens it can be sprayed on every vegetable.

Pay close attention to crop listings, application rates, and pre-harvest intervals.

10. Should I use more than one grasshopper product?

Usually, you should think in terms of combining control methods, not simply stacking pesticides.

Monitoring, weed management, physical barriers, biological control, and properly selected insecticides can all play different roles.

Never mix pesticide products unless the labels specifically permit the combination.

Final Verdict: Which Grasshopper Killer Should You Buy?

The best grasshopper killer for your garden depends less on finding one “magic” product and more on choosing the right control approach for your situation.
