It’s important for anyone who likes plants to know what leafhoppers are, why they’re a big deal, and what kind of trouble they can cause.
These little bugs snack on plant sap and leave a path of destruction behind. This can stop plants from growing properly and cause lasting harm.
In this guide, we’ll explain what leafhoppers are, how to spot them, the damage they do, and most importantly, we’ll give you ways to naturally get rid of them.
Whether you’re a pro gardener or just starting out with plants, this info will help you keep your green friends safe.
What are Leafhoppers?
Leafhoppers are very tiny bugs, usually only 3 to 15 millimeters long. They are known for their bright colors and their bodies that look like wedges.
These little bugs can jump really far when they get scared because they have strong back legs. Leafhoppers eat by poking plants and drinking their juices with their pointy mouths.
They go through three stages in their life: eggs, baby leafhoppers (called nymphs), and grown-up leafhoppers.
The baby leafhoppers look like smaller versions of the grown-ups. To control leafhoppers, it’s important to know how they look and act.
How to Find Leafhoppers
Finding leafhoppers early is important. Look for small, colorful bugs with wedge-shaped bodies that jump around a lot.
Check the underside of leaves because leafhoppers like to hide there. Sometimes, they leave a sticky stuff called honeydew on plants, which can attract ants and cause mold.
When there are a lot of leafhoppers, plants can get hurt. Their leaves might turn yellow or brown, get little dots on them, and they might not grow well.
These are signs that leafhoppers are causing problems for the plants.

Damage Caused by Leafhoppers
Leafhoppers are tiny insects that can make plants very unhappy. They like to drink the juice from plants, and this can cause lots of problems. Here’s what happens when leafhoppers visit your plants:
1. Slow Growth
Leafhoppers feed on the plant’s sap, disrupting its ability to transport essential nutrients.
This disruption stunts the plant’s growth, causing it to remain undersized and weak.
2. Twisted Leaves
As leafhoppers feed on the plant’s sap, they inject a substance that disrupts normal growth patterns.
This can result in twisted, curled, or deformed leaves, giving your plant an unhealthy and distorted appearance.
3. Change in Color
The damage caused by leafhoppers can lead to a change in the color of the plant’s leaves.
Infested leaves may turn yellow, brown, or even silver, indicating stress and reduced photosynthesis.
4. Fewer Fruits and Flowers
For gardeners and plant enthusiasts, the reduced yield of fruits or flowers is especially disheartening.
Leafhoppers’ sap-sucking activities can hinder the plant’s ability to produce the desired fruits and flowers, resulting in a less productive garden.
5. Spreading Plant Sickness
Some species of leafhoppers act as vectors for plant diseases. They can pick up pathogens from one plant and transmit them to another as they feed.
This makes leafhoppers not only a direct threat but also potential carriers of plant illnesses that can further weaken your green companions.

10 Methods On How To Get Rid Of Leafhoppers Naturally
1. Pruning and Removing Affected Leaves
Pruning and removing affected leaves is a fundamental method to control leafhopper infestations.
Begin by inspecting your plants regularly for signs of leafhoppers. Once identified, carefully trim and discard leaves that exhibit severe leafhopper damage.
This not only removes the pests themselves but also eliminates their feeding and breeding grounds. Be sure to dispose of the pruned leaves away from your garden to prevent any chance of re-infestation.
Additionally, consider improving the overall health of your plants through proper pruning techniques. Well-maintained, vigorous plants are more resilient to leafhopper attacks. By encouraging new growth and maintaining a tidy garden, you create an environment less conducive to these tiny, sap-sucking insects.
2. Neem Oil Spray
Neem oil, derived from the neem tree, is a natural insecticide that can effectively deter and control leafhoppers. Neem oil disrupts the leafhoppers’ feeding and reproductive capabilities.
To use neem oil, mix it with water according to the manufacturer’s instructions and spray it on your plants, covering both sides of the leaves. Ensure you apply neem oil during cooler parts of the day to avoid harming beneficial insects that might be active during warmer periods.
Neem oil not only repels leafhoppers but also interferes with their growth and development. Over time, it can reduce the population of leafhoppers in your garden. Regular applications may be necessary, especially if you experience heavy leafhopper infestations or if rain washes away the protective coating.
3. Insecticidal Soap
Insecticidal soap is a safe and effective option for targeting leafhoppers and their nymphs. This natural remedy works by disrupting the protective waxy coating on leafhoppers, ultimately dehydrating and killing them. It is crucial to use a soap specifically formulated for plants, as household dish soap may harm your vegetation.
To apply insecticidal soap, mix it with water as directed on the product label and spray it directly onto the leafhoppers and affected plant areas. Ensure thorough coverage, including the undersides of leaves where leafhoppers often hide. Repeat applications as needed, particularly after rainfall or irrigation, which can wash away the soap’s residue.
4. Beneficial Insects
Employing beneficial insects is a biological and eco-friendly approach to controlling leafhoppers. Predators like ladybugs, lacewings, and parasitic wasps are natural enemies of leafhoppers and can significantly reduce their populations.
To attract these beneficial insects to your garden, consider planting nectar-rich flowers, such as marigolds and alyssum, which provide them with food sources. You can also purchase these predators from reputable suppliers and release them into your garden. By fostering a diverse ecosystem, you create a natural balance that keeps leafhoppers and other pests in check.
5. Row Covers
Row covers are physical barriers that shield your plants from leafhoppers and other insect pests. These lightweight, breathable fabrics are draped over your crops, creating a protective shield while allowing sunlight and rain to reach the plants. Row covers are particularly effective for preventing initial infestations or safeguarding young seedlings vulnerable to leafhopper damage.
When using row covers, ensure they are securely anchored to the ground to prevent leafhoppers from finding their way underneath. Regularly inspect and adjust the covers to maintain their integrity. Row covers can be especially useful in vegetable gardens and can be removed when plants start flowering, allowing for pollination.
6. Companion Planting
Companion planting is a strategic gardening technique that involves planting certain species alongside one another to deter pests. When it comes to leafhoppers, marigolds, nasturtiums, and petunias are excellent companion plants known for their ability to repel these insects.
Marigolds, with their strong-smelling foliage, emit a scent that leafhoppers find unappealing, making them an effective deterrent. Nasturtiums and petunias also possess repellent properties that can help protect your plants. Interplant these flowers with your vulnerable crops or place them strategically throughout your garden to create a natural barrier against leafhoppers.
7. Water Management
Proper water management can play a significant role in leafhopper control. Leafhoppers are attracted to moisture, so avoiding overwatering can help reduce their presence in your garden. Water your plants at the base rather than overhead to keep the foliage dry.
Additionally, consider implementing a drip irrigation system or soaker hoses to deliver water directly to the root zone, minimizing leaf wetness. By reducing the humidity around your plants, you make your garden less inviting to leafhoppers, decreasing the likelihood of infestations.
8. Diatomaceous Earth
Food-grade diatomaceous earth (DE) is a natural and non-toxic substance that can be applied to plants as a physical barrier against leafhoppers and other crawling insects. DE is composed of tiny, sharp particles that pierce the exoskeleton of pests, causing them to dehydrate and perish.
Apply DE by dusting it onto the leaves of your plants and the surrounding soil. Focus on areas where leafhoppers are most likely to feed and congregate. Reapply after rain or heavy dew, as DE is most effective when dry. Take care not to inhale DE dust during application and use a mask if necessary to protect your respiratory health.
9. Essential Oils
Essential oils, such as peppermint, eucalyptus, and rosemary, have aromatic properties that can deter leafhoppers and other garden pests. To create a homemade essential oil spray, mix a few drops of your chosen oil with water and a mild liquid soap as an emulsifier.
Spray the solution onto your plants, focusing on areas where leafhoppers are active. Reapply as needed, especially after rain or heavy irrigation. These essential oils not only act as repellents but can also mask the scents that attract leafhoppers to your garden, making it less appealing to them.
10. Crop Rotation
Crop rotation is a long-term strategy to disrupt leafhoppers’ favored host plants. Leafhoppers often have specific preferences for certain crops, and by moving these crops to different areas of your garden each season, you can make it more difficult for leafhoppers to establish themselves.
Develop a crop rotation plan that takes into account the plants most vulnerable to leafhoppers and other pests. By consistently changing the planting locations of susceptible crops, you break the life cycle of leafhoppers and reduce their ability to infest your garden.
5 Effective Strategies On How To Prevent Leafhoppers
1. Regular Inspection
Prevention begins with vigilance. Regularly inspect your plants for early signs of leafhopper activity, such as yellowing leaves, stippling, or the presence of honeydew. Early detection allows for prompt intervention, reducing the potential for damage.
Develop a routine inspection schedule, especially during the warmer months when leafhoppers are most active. By catching leafhoppers in their early stages, you can prevent their numbers from escalating and causing widespread damage.
2. Weed Management
Effective weed management is essential in leafhopper prevention. Weeds can provide shelter and alternative food sources for leafhoppers, creating an environment conducive to infestations.
Keep your garden weed-free by regularly removing unwanted vegetation. Apply mulch to suppress weed growth and maintain a clean, tidy garden space that discourages leafhopper habitation.
3. Proper Plant Spacing
Leafhoppers are less likely to infest crowded plantings. Proper plant spacing ensures that plants have adequate air circulation and room to grow without being in close proximity to one another.
Refer to the recommended spacing guidelines for each plant species in your garden. By adhering to these guidelines, you create an environment that is less favorable for leafhoppers to establish themselves.
4. Mulching
Mulching not only conserves soil moisture but also discourages leafhoppers from setting up shop in your garden. A layer of mulch helps to maintain consistent soil moisture, reducing the attractiveness of your plants to leafhoppers, as they are drawn to moisture.
Apply mulch around the base of your plants, leaving a small gap around the stem to prevent rot. Organic mulch, such as straw or wood chips, is ideal for promoting soil health and deterring leafhoppers.
5. Attract Beneficial Insects
Create a garden environment that welcomes beneficial insects, such as ladybugs, lacewings, and parasitic wasps, which naturally prey on leafhoppers. To attract these helpful allies, plant nectar-rich flowers and herbs that provide them with sustenance.
Additionally, avoid using broad-spectrum pesticides that can harm beneficial insects along with the pests. By maintaining a balanced ecosystem, you’ll have a natural defense against leafhoppers and other garden threats.
Implementing these methods for natural leafhopper control and prevention can help you maintain a healthy, thriving garden while minimizing the need for chemical treatments.
Whether you’re dealing with an existing leafhopper infestation or aiming to safeguard your plants, these eco-friendly approaches are effective and environmentally responsible solutions.
