A Comprehensive Guide to Identification, Damage, and Control

Leafhoppers are small, sap-sucking insects that can cause significant damage to plants and gardens. These pests are found throughout the world and can affect a wide variety of plant species. In this article, we will provide a detailed description of leafhoppers, how they cause damage to plants, and how to identify them. We will also provide several natural methods for dealing with these pests, followed by other methods of pest management.


Leafhoppers are small, wedge-shaped insects that range in size from 1/8 to 1/2 inch long. They are typically green, yellow, or brown in color and have wings that fold over their backs like a roof. Leafhoppers are active during the day and can be found on the undersides of leaves, stems, and other plant parts. They have piercing-sucking mouthparts that they use to feed on plant sap.



Leafhoppers can cause damage to plants in several ways. First, they suck the sap from the plant, which can cause leaves to yellow and curl, and can stunt growth. This can be particularly damaging to young plants, which may not be able to recover from heavy infestations. Additionally, leafhoppers can transmit plant diseases, such as aster yellows, potato leaf roll virus, and tomato spotted wilt virus, to susceptible plants.


Natural Control Methods

  1. Handpicking: One effective method for controlling leafhoppers is to physically remove them from the plant by hand. This can be done by carefully examining the plant and plucking the insects off with your fingers. Be sure to check the undersides of leaves and stems, as this is where leafhoppers often congregate.

  2. Beneficial Insects: Encouraging beneficial insects, such as ladybugs and lacewings, to take up residence in your garden can also help control leafhoppers. These insects are natural predators of leafhoppers and will feed on them if they are present in the garden.

  3. Neem Oil: Neem oil is a natural pesticide that can be used to control leafhoppers. Mix one tablespoon of neem oil with one quart of water and spray the mixture on the affected plants. Repeat every seven to ten days as needed.

  4. Reflective Mulch: Reflective mulch can help deter leafhoppers from feeding on plants. Cover the soil around the plants with aluminum foil or reflective plastic, as this will reflect light and create a confusing environment for the insects.

  5. Essential Oils: Essential oils such as peppermint, rosemary, and clove can be effective in repelling leafhoppers. Dilute a few drops of the essential oil with water and spray on the plants. Repeat every few days as needed.

Other Methods of Pest Management:

If natural methods of pest control are not effective, there are several other methods that can be used to manage leafhopper infestations. These include:

  1. Insecticidal Soap: Insecticidal soap can be effective in controlling leafhoppers. Mix one tablespoon of soap with one quart of water and spray the mixture on the affected plants. Repeat every seven to ten days as needed.

  2. Pyrethrin: Pyrethrin is a natural insecticide that can be used to control leafhoppers. Mix according to the instructions on the label and spray on the affected plants.

  3. Chemical Pesticides: Chemical pesticides can also be used to control leafhoppers. However, it’s important to use these products only as a last resort, as they can be harmful to beneficial insects and can also have negative effects on the environment.



Leafhoppers are a common pest that can cause significant damage to plants and gardens. Fortunately, there are several natural methods for dealing with these pests, including handpicking, encouraging beneficial insects, using neem oil, using reflective mulch, and using essential oils. If these methods are not effective, there are other methods of pest management, such as insecticidal soap, pyrethrin, and chemical pesticides. It’s important to use these methods responsibly and only as a last resort.

In Live Oak, FL (USDA Zone 8B), leafhoppers can be particularly problematic during the summer months when temperatures are high and plants are actively growing. In addition to the natural methods mentioned above, there are some specific steps that can be taken to manage leafhoppers in this region. These include:

  1. Plant Selection: Choosing plants that are less susceptible to leafhopper damage can help reduce the risk of infestation. Some examples of plants that are less attractive to leafhoppers include herbs, such as thyme and rosemary, and ornamental grasses.

  2. Monitoring: Regularly monitoring plants for signs of leafhopper damage can help catch infestations early and prevent them from spreading. Look for yellowing or curling leaves, stunted growth, and distorted plant parts.

  3. Watering: Proper watering can help keep plants healthy and less susceptible to leafhopper damage. Water plants deeply and infrequently, rather than giving them frequent shallow waterings.

  4. Mulching: Mulching around plants can help maintain soil moisture and create a barrier between the plant and any potential pests. Use organic mulch, such as straw or shredded leaves, and avoid piling it too close to the plant stem.

By implementing these strategies and taking proactive measures to manage leafhopper infestations, gardeners in Live Oak, FL (USDA Zone 8B) can protect their plants and keep them healthy throughout the growing season.
