Disease and Pests Cicada Tree Damage: A Guide to Identification and Management
As an arborist with many years of experience, I’ve witnessed disease and pests cicada tree damage firsthand. When female cicadas lay their eggs under the bark of twigs or branches, they create openings that allow pathogens and pests to enter. This can lead to leaf wilting, yellowing, and leaf drop, potentially weakening the tree and leaving it vulnerable to further harm.
However, with proper care and management, you can mitigate the impact of disease and pests cicada tree damage and protect your trees from long-term harm:
1. Identify the Signs of Damage:
- Wilting
- Yellowing or browning leaves
- Leaf drop
- Branch dieback
- Stress
- Susceptibility to other pests and diseases
2. Best Practices for Prevention:
- Postpone planting new trees: Before the expected emergence of cicadas, delay planting for a couple of years.
- Protect young trees: Use tree wraps or guards to safeguard bark from egg-laying cicadas.
- Physical exclusion: Create barriers to prevent cicadas from accessing young trees.
3. Management and Treatment:
- Prune infected branches: Remove branches that show signs of egg-laying or dieback.
- Improve tree health: Provide adequate water and fertilizer to support tree recovery.
- Avoid chemical treatments: Insecticides may harm beneficial insects and prove ineffective against cicadas.
4. Monitoring and Care:
- Regular inspections: Monitor trees for damage and take prompt action as needed.
- Long-term care: Even after cicada damage, continue to provide proper tree care, including watering, pruning, and pest management, to maintain tree health and longevity.
By understanding these signs, preventive measures, and management strategies, you can help prevent and mitigate the impact of disease and pests cicada tree damage, preserving the health and beauty of your trees.

Prevention of Cicada Tree Damage
Cicadas can be a nuisance to our trees, and yet the damage can be prevented. Here’s how:
Proper Tree Selection:
- Opt for tree species that are less appealing to cicadas for egg-laying.
Tree Protection:
- Wrap your tree trunk and branches with fine mesh or netting to deter female cicadas from laying eggs.
Tree Care:
- Ensure your trees are well-hydrated and have access to nutrients to boost their resilience against cicada damage.
Other Tips:
- Avoid chemical treatments as they can be ineffective and harmful to beneficial insects.
- Regularly inspect your trees for signs of damage and take prompt action if needed.
Key Takeaways:
- Choose wisely: Select tree species less appealing to cicadas.
- Embrace protection: Wrap trunks and branches to prevent egg-laying.
- Provide TLC: Water and fertilize your trees to enhance their resilience.

Treatment of Cicada Tree Damage
As an arborist, I’ve witnessed firsthand the impact of cicadas on trees. While they’re fascinating insects, their egg-laying habits can leave trees vulnerable. But fear not! There are proven strategies to mitigate cicada tree damage.
Key Takeaways:
- Cicada damage occurs when female cicadas lay eggs in tree bark, creating entry points for pathogens.
- Symptoms include wilting leaves, yellowing/browning foliage, and branch dieback.
- Pruning infected branches helps reduce the cicada population and aids recovery.
- Proper tree care (watering, fertilizing) enhances tree resilience to cicada damage.
- Preventive measures like tree wraps and barriers can minimize egg-laying.
Steps for Treatment of Cicada Tree Damage:
- Remove Infected Branches: Pruning affected branches helps remove egg-laying sites and promotes new growth.
- Water and Fertilize Trees: Ensure trees have adequate hydration and nutrients to support their recovery.
- Avoid Chemical Treatments: Insecticides are generally ineffective against cicadas and can harm beneficial insects.
- Monitor Trees: Regularly inspect trees for further damage and take prompt action as needed.
Remember, while cicada damage can be stressful, most trees can recover with proper treatment. By adopting these strategies, you can safeguard your trees from long-term harm caused by these captivating insects.

Importance of disease and pest management for cicada trees
Cicadas are usually harmless to us humans, but they can do some serious damage to cicada trees. Female cicadas lay their eggs in the twigs and branches of these trees, which can cause the branches to wilt, turn yellow or brown, and even die back. The weakened tree is then more susceptible to other pests and diseases. The truth is, you can’t completely prevent cicada damage, but there are things you can do to reduce the risk. Let’s dive into some key points:
Proper tree care: Healthy trees are more resistant to cicada damage, so make sure your trees are getting the water, fertilizer, and sunlight they need.
Tree wraps and guards: Wrapping the trunks and branches of young trees with tree wraps or guards can prevent female cicadas from laying their eggs.
Pruning: You can also prune away any branches that show signs of egg-laying or dieback. Take care not to cut into healthy wood as that can lead to infection.
Barriers: You can create physical barriers around your trees to make it more difficult for cicadas to reach them. Mesh or netting can be used to cover the canopy.
Avoid chemical treatments: Chemical treatments are usually ineffective against cicadas and can harm beneficial insects.
Monitor your trees: Regularly inspect your trees for signs of damage and take prompt action if necessary.
Key Takeaways:
- Tree health: Ensure trees are well-watered and fertilized for enhanced resilience against cicada damage.
- Physical barriers: Protect young trees with tree wraps or guards, and use mesh or netting to create barriers around trees, making it difficult for cicadas to access them.
- Pruning: Remove branches showing egg-laying signs or dieback to prevent further damage and promote tree health.
- Monitor and inspect: Regularly check your trees for damage and take prompt action to minimize cicada impact.
