What Are Grasshoppers Attracted To – Safeguarding Your Garden
Grasshoppers are primarily attracted to lush, green vegetation, particularly broadleaf plants, grasses, and certain common garden vegetables. They seek out areas with abundant food sources, especially during dry periods when their preferred wild forage might be scarce.
Factors like overgrown weeds, sunny locations, and readily available moisture (even from dew on leaves) can also make your garden an inviting buffet for these voracious chewers.
Gardeners often face a myriad of challenges, and few are as disheartening as discovering your carefully nurtured plants have become an insect’s latest meal. Among the most common culprits are grasshoppers, those seemingly harmless hopping insects that can, in large numbers, decimate a garden overnight. Understanding their habits is the first step in effective garden protection.
If you’ve ever wondered, “what are grasshoppers attracted to?” you’re asking a crucial question for the health and vitality of your landscape. Knowing their preferences allows you to anticipate their arrival, implement preventative measures, and protect your precious plants from significant damage.

Understanding What Are Grasshoppers Attracted to: Their Preferred Menu
Grasshoppers are opportunistic feeders, but they certainly have their favorites. Knowing their dietary preferences is key to understanding why they might be targeting your specific plants. They are primarily herbivores, consuming a wide variety of plant material.
Their Favorite Plant Buffet
Many common garden plants top the grasshopper’s list. They particularly favor tender, succulent leaves and stems.
You’ll often find them munching on:
- Leafy Greens: Lettuce, spinach, kale, and chard are highly susceptible. Their soft texture makes them easy targets.
- Beans and Corn: Both young bean plants and corn silk, leaves, and even developing kernels are prime targets.
- Carrots and Onions: While they might not eat the root, grasshoppers relish the green tops of these vegetables.
- Grains: If you’re growing ornamental grasses or have nearby fields, wheat, oats, and barley are major attractants.
- Alfalfa and Clover: These legumes are significant forage crops and a huge draw for grasshopper populations.
- Ornamental Flowers: Sunflowers, zinnias, and marigolds can also fall victim, especially their petals and leaves.
It’s important to note that grasshopper preferences can shift based on local availability and environmental conditions. During droughts, they become less picky.
Ideal Habitats and Environmental Factors
Beyond specific plants, certain conditions and environments make your garden particularly inviting. Grasshoppers thrive in warm, sunny areas.
They are drawn to:
- Overgrown Areas: Tall grasses, unkempt borders, and weedy patches provide both shelter and a continuous food supply. This is a common breeding ground.
- Sunny, Dry Conditions: While plants suffer in drought, grasshoppers often flourish. Stressed plants may become even more appealing, and dry soil is ideal for egg-laying.
- Adjacent Fields: Gardens bordering pastures, hayfields, or natural grasslands are at higher risk. Grasshoppers migrate from these areas when their food supply diminishes.
- Undisturbed Soil: Female grasshoppers lay their eggs in undisturbed soil, often in grassy areas or along field edges. Tilling can disrupt this process.
Understanding these environmental cues helps you identify potential hotspots in your own yard. A proactive approach means looking beyond just the plants themselves.
Grasshopper Life Cycle: Timing Your Defense
Knowing the grasshopper’s life cycle is crucial for effective management. Your preventative measures will be most impactful when timed correctly.
From Egg to Adult: A Seasonal Journey
Grasshoppers typically have one generation per year, though this can vary by species and climate. Their life cycle directly influences when and how you should act.
The cycle generally involves:
- Egg Stage (Fall to Spring): Females lay egg pods in the soil, usually in late summer or fall. These eggs overwinter.
- Nymph Stage (Spring to Early Summer): Eggs hatch in late spring or early summer, depending on soil temperature. These young grasshoppers, called nymphs, are smaller, wingless versions of adults. They begin feeding immediately.
- Adult Stage (Summer to Fall): Nymphs mature through several molts into winged adults by mid-summer. Adults are the most damaging stage, capable of widespread defoliation. They also mate and lay eggs, perpetuating the cycle.
The period from late spring through mid-summer is when you need to be most vigilant. Catching nymphs early can prevent a major infestation by adults.
Spotting the Damage: Early Detection Is Key
Grasshopper damage is usually quite distinct. Early identification allows for swift intervention, saving your plants from further harm.
Recognizing the Tell-Tale Signs
Unlike slugs or caterpillars, grasshoppers leave a specific signature. Keep a close eye on your plants, especially during warm, dry periods.
Look for:
- Ragged Holes in Leaves: Grasshoppers chew irregularly shaped holes, often starting from the leaf edges. This is their most common form of damage.
- Defoliation: In severe infestations, entire leaves or even whole plants can be stripped bare, leaving only tough stems or veins.
- Chewed Stems and Flowers: They don’t just stick to leaves. Tender stems, flower buds, and petals can also be consumed.
- Frass (Excrement): You might notice small, dark, pellet-like droppings on leaves or around the base of affected plants.
- Visible Pests: Of course, seeing the grasshoppers themselves is the most direct evidence. Check plants during the warmest parts of the day when they are most active.
Don’t confuse grasshopper damage with that of slugs, which leave slime trails, or caterpillars, which often leave cleaner-cut holes or skeletonized leaves.
Proactive Prevention: Making Your Garden Less Appealing
The best offense is a good defense, especially when it comes to garden pests. Implementing preventative strategies can significantly reduce your chances of a grasshopper invasion.
Cultural Practices to Deter Grasshoppers
These are everyday gardening practices that contribute to overall garden health and make it less attractive to pests.
Consider these proactive steps:
- Keep Your Garden Tidy: Remove weeds and tall grasses from around your garden beds. This eliminates shelter and reduces food sources for nymphs.
- Till in the Fall: Lightly tilling areas where grasshoppers might lay eggs (e.g., grassy borders) can expose or destroy egg pods before they hatch in spring.
- Rotate Crops: If you’ve had a grasshopper problem in one area, avoid planting their favorite crops there the following season. This breaks their life cycle.
- Encourage Natural Predators: Birds, praying mantises, spiders, and even some types of wasps prey on grasshoppers. Provide habitat for these beneficial creatures.
- Plant Resistant Varieties: While grasshoppers are generalists, some plants are less appealing. Consider plants like squash, tomatoes, peas, cilantro, dill, mint, and garlic.
A healthy garden ecosystem naturally resists pests. Focus on soil health, proper watering, and diverse plantings to build resilience.
Physical Barriers and Repellents
Sometimes, you need a more direct approach to keep grasshoppers out of specific areas. Physical barriers are an excellent non-toxic option.
Effective physical deterrents include:
- Row Covers: For young, vulnerable plants, lightweight floating row covers can physically block grasshoppers while still allowing light and water through. Secure the edges to prevent entry.
- Hand-Picking: For smaller gardens, early morning hand-picking can be effective. Grasshoppers are slower when temperatures are cooler. Drop them into a bucket of soapy water.
- Diatomaceous Earth (DE): This natural powder, made from fossilized diatoms, can be sprinkled around plants. It works by abrading the grasshopper’s exoskeleton, causing dehydration. Apply when plants are dry.
- Garlic or Pepper Sprays: Some gardeners find success with homemade repellent sprays using strong-smelling ingredients like garlic or hot peppers. These typically need frequent reapplication, especially after rain.
Always wear gloves when handling diatomaceous earth, as it can be an irritant. Apply it carefully to avoid inhaling the dust.
Effective & Safe Control Methods
When prevention isn’t enough, you might need to employ more direct control methods. Always prioritize safety and environmental impact.
Organic and Low-Impact Solutions
For the home gardener, starting with organic and least-toxic options is always recommended to protect beneficial insects and wildlife.
Consider these options:
- Beneficial Nematodes: Certain species of nematodes can parasitize grasshopper nymphs in the soil, offering a biological control. Apply them to moist soil in areas where eggs are likely to hatch.
- Neem Oil: Derived from the neem tree, this oil acts as an anti-feedant and growth regulator, disrupting the grasshopper’s life cycle. It’s most effective on nymphs. Apply according to label instructions, typically in the cooler parts of the day.
- Insecticidal Soaps: These soaps work by breaking down the insect’s outer protective layer. They are effective on nymphs and require direct contact. Always test on a small area first to ensure plant compatibility.
- Nosema locustae: This is a naturally occurring protozoan that specifically infects and kills grasshoppers and crickets. It’s slow-acting but can significantly reduce populations over time. It’s applied as a bait.
When using any spray, always read the label thoroughly. Ensure it’s safe for your specific plants and won’t harm bees or other beneficial pollinators.
When to Call in the Pros
Sometimes, despite your best efforts, a grasshopper infestation can become overwhelming, especially in larger landscapes or during severe regional outbreaks. This is when professional help might be warranted.
Consider professional intervention if:
- Widespread Damage: Your entire garden or lawn is suffering significant, irreversible damage.
- Large-Scale Infestation: You’re seeing hundreds or thousands of grasshoppers, indicating a regional issue beyond a single garden.
- Safety Concerns: You’re uncomfortable using certain pesticides or lack the equipment for large-scale application.
- Persistent Problem: Despite trying multiple methods, the problem recurs year after year with increasing severity.
A professional landscaper or pest control expert can assess the situation, identify the specific species, and recommend targeted, often more potent, solutions that might not be available to the average homeowner. They can also advise on long-term ecological solutions.
Frequently Asked Questions About Grasshoppers
Here are some common questions homeowners and gardeners ask about these persistent pests.
Q: Will Grasshoppers Eat My Flowers?
A: Yes, grasshoppers are not picky and will often feed on ornamental flowers, especially those with tender leaves and petals like sunflowers, zinnias, and even some roses if other food sources are scarce. They’re primarily attracted to broadleaf plants, whether they’re vegetables or ornamentals.
Q: Are Grasshoppers Attracted to Light?
A: Unlike many night-flying insects, grasshoppers are generally not attracted to light. They are diurnal, meaning they are active during the day, especially in warm, sunny conditions. Light traps are not effective for grasshopper control.
Q: What Plants Repel Grasshoppers Naturally?
A: While no plant is 100% grasshopper-proof, some are less appealing. These include plants with strong odors or tough textures such as tomatoes (though they might eat young plants if desperate), squash, peas, cilantro, dill, mint, garlic, and sometimes certain herbs like oregano and thyme. Planting these among more vulnerable crops can offer some deterrent effect.
Q: Does Tilling in Spring Help With Grasshoppers?
A: Tilling in late fall or early spring can help disrupt overwintering grasshopper egg pods in the soil. Fall tilling is often more effective as it exposes the eggs to harsh winter conditions, leading to desiccation or predation. Spring tilling can also help, but some eggs might already be close to hatching.
Q: Can I Use Chickens or Ducks to Control Grasshoppers?
A: Yes, free-ranging chickens and ducks are excellent natural predators of grasshoppers and can significantly reduce populations. However, be mindful that they can also damage young plants, scratch up beds, and eat seedlings. Consider supervised release or using mobile chicken tractors to manage their impact on your garden beds.
