How to get rid of leafrollers is essential, as these pests can affect various plants, including fruit trees, ornamental shrubs, and vegetable crops.
These insects, often the larvae of moths, roll themselves inside leaves and feed on the foliage, causing damage to the plant.
Read this article, as we have provided how to get rid of leafrollers in 4 easy steps.
Step 1: How To Identify the Leafroller (Identification)
Before knowing how to get rid of leafrollers, identification is crucial.
- The majority of leafroller larvae have colours that range from dark to light green, cream, brown, or yellow.
- Slender, cylindrical bodies with brown or black head capsules are characteristic.
- has pairs of leg-like appendages running the length of its abdomen, which aid in the leafroller’s rapid, backward movement to avoid danger.
- They grow to a length of 2/3 to 3/4 inches when in the larval stage.

Step 2: How To Inspect For the Leafroller (Inspection)
Before knowing how to get rid of leafrollers, inspection is necessary.
The feeding behaviour of leafroller larvae results in a tattered or curled appearance because the pest rolls up its leaves and occasionally wraps them in silk.
To avoid predators, these rolled-up leaves are located at the highest point of the branch stem.
During the day in the spring, you will either see the eggs or the larvae. Leafroller eggs are placed in big, overlapping clusters on leaves or branches. A liquid coating that is initially dark grey or brown eventually turns bleach white.
Step 3: How To Get Rid of Leafroller (Control)
- Apply Supreme IT:
- Measure the Treatment Site:
- Measure the length and width of the treatment site in feet.
- Calculate Square Footage:
- Multiply the length by the width to calculate the square footage of the treatment site. The formula is: Square Footage= length × width.
- Determine the Application Rate:
- The recommended application rate is 0.25 to 0.5 ounces of Supreme IT per gallon of water per 1,000 square feet.
- Calculate Pesticide Amount:
- Multiply the square footage by the chosen application rate to determine the amount of Supreme IT needed. The formula is Pesticide Amount (oz) = Square Footage×(Application Rate (oz/gallon)).
- Prepare the Solution:
- Mix the calculated amount of Supreme IT with the appropriate volume of water. For example, if preparing a gallon of solution, mix the calculated amount with one gallon of water.
- Apply the Solution:
- Apply the prepared Supreme IT solution to the treatment site. Ensure thorough coverage, especially targeting areas prone to leafroller infestation.
- Measure the Treatment Site:
Perform a spot treatment with a handheld pump sprayer. Pour half of the water into the spray tank, add the specified amount of Supreme IT, and then top it off with the other half of the water to create your spray solution.
Once the solution is well combined, shut the tank lid and give it a shake. Leaves on plants should be sprayed from top to bottom until damp, but not so much that they run off.
- Carry Out Pruning:
Use a pair of hedge trimmers or hand pruners as your tools for the task. Ensure that the tools are sharp and well-maintained for effective and clean cuts.
Inspect the plant for any decaying or dead tree limbs. These can be branches that show signs of disease, pest infestation, or general decay. Use the selected tools to carefully remove these limbs, making clean cuts near the main stem or trunk.
Remove any remaining fruits, nuts, or plant buds that are present on the plant. This is especially important if these parts are decaying or if the plant is entering a dormant phase. Prune them away using the hedge trimmers or hand pruners.
Clear the plant of leaves before it enters dormancy. Use the selected tools to trim or prune away the leaves. This not only helps in removing decaying foliage but also prepares the plant for its dormant phase.
If there are rolled leaves on the plant stems, use your selected tool to directly remove them. Rolled leaves can be a sign of pest infestation or disease, and their removal can help in managing these issues.
Collect and dispose of the removed plant material, including decaying limbs, fruits, nuts, buds, and leaves. Proper disposal can help prevent the spread of diseases or pests.
After completing the pruning or trimming, clean and disinfect your tools. This reduces the risk of transmitting diseases from one plant to another.

Step 4: How To Prevent the Leafroller (Prevention)
After knowing how to get rid of leafrollers, prevention is the next big step
- Leafrollers feed on and grow from the inside of rolled-up leaves; therefore, prune any rotting leaves, fruits, and branches that are hanging from the stem.
- Remove any remaining plant debris and leaves from the ground to cut down on potential leafroller habitats and feeding sources.
- To keep your lawn healthy and get rid of more potential food sources, mow it when it is three inches high.
- Once a week, give your grass and decorative foliage an inch of irrigation to discourage leafroller eggs and preserve plant health.
- Apply Supreme IT consistently every ninety days to stop and prevent leafrollers.

To prevent leafroller infestations, apply a long-lasting residual insecticide like Supreme IT every 90 days and maintain regular lawn maintenance such as raking, mowing, and pruning.
Addressing leafrollers in plants requires a comprehensive approach involving identification, monitoring, and effective control measures.
