Cicadas are fascinating insects, known for their loud mating calls and unique life cycles spanning several years. While their sounds can evoke nostalgia and symbolize the essence of summer, they can also pose a significant threat to your garden. With the resurgence of cicadas, particularly after a long dormancy period, many gardeners face the challenge of how to fend off these creatures without resorting to harmful pesticides. In this comprehensive guide, we will explore effective strategies for protecting your garden from cicadas, ensuring your plants thrive during their swarming season.
Understanding Cicadas: The Basics
To effectively protect your garden, it’s essential to understand cicadas and their behavior.
A Brief Overview of Cicadas
Cicadas belong to the order Hemiptera and are known for their distinctive exoskeletons and vibrant sounds, generated by males to attract females. These insects primarily emerge in the late spring and summer months, and depending on their species, they can appear every year or on a cycle, such as the well-known 17-year cicadas.
Lifecycle of Cicadas
The life cycle of cicadas includes several stages:
- Egg Stage: Females lay eggs in slits created in tree branches.
- Nymph Stage: After hatching, nymphs fall to the ground and burrow into the soil to feed on plant roots.
- Adult Stage: After several years, nymphs emerge from the ground, molt into adults, and begin the cycle again.
Understanding this life cycle is vital for informing your protective measures, particularly during the egg-laying phase.
Recognizing the Threat of Cicadas in Your Garden
Cicadas primarily threaten gardens by feeding on the sap of plants and laying eggs. Their feeding can weaken plants, while their egg-laying behavior can cause branch dieback.
Potential Damage to Plants
While cicadas are not harmful in the same way that some pests might be, their feeding habits can lead to several issues:
- Branch Dieback: Female cicadas cut into woody stems to lay eggs, creating an entry point for diseases.
- Weakened Plants: Prolonged feeding can deplete the plant’s resources, leading to stunted growth or moribund plants.
Understanding the nature of the threat allows you to take preventive action at the right time.
Prevention Strategies for Protecting Your Garden
There are several methods to safeguard your garden from cicadas. The effectiveness of these strategies often depends on your specific garden layout and plant types.
Physical Barriers
One of the most effective ways to keep cicadas away from your plants is to create physical barriers.
Netting and Row Covers
Utilizing insect netting can deter cicadas from reaching your plants. Lightweight row covers work effectively as barriers while allowing sunlight and moisture to penetrate.
When applying netting:
- Secure the edges to the ground to prevent cicadas from crawling underneath.
- Ensure the netting has small enough openings to keep cicadas out while allowing beneficial insects access.
Timing Your Planting
Planting and harvesting times can play an enormous role in cicada management. Ideally, you want to plan your planting schedule around the cicada lifecycle.
Optimal Planting Times
If you know when cicadas are likely to emerge in your region, you can plan to have your most vulnerable plants either harvested before their emergence or planted after they have passed. This proactive approach can avert potential damage.
Choosing Resistant Plant Varieties
Some plant varieties are more resistant to cicada damage than others. By selecting these resilient plants, you can reduce your garden’s vulnerability.
Examples of Resistant Plants
Many gardeners have found success using certain trees and shrubs known for their durability against cicadas:
| Plant Type | Resistance Level |
|---|---|
| Oak | High |
| Maple | Moderate |
| Pine | High |
| Fruit Trees | Low (varying by species) |
Choosing these types of plants can mitigate the risk of significant damage.
Cultural Practices to Deter Cicadas
Incorporating certain cultural practices into your gardening routine can also help keep cicadas at bay.

What are cicadas and why are they a concern for gardens?
Cicadas are large, flying insects known for their distinctive sound and life cycle. They are primarily known for emerging in large swarms, typically every 13 to 17 years, depending on the species. While they are generally harmless to humans, cicadas can pose a significant threat to gardens and plants as they feed on sap from trees, shrubs, and other plants. Their feeding can result in stress or damage to plants, which may lead to stunted growth or even death in severe cases.
Furthermore, cicadas lay their eggs in the stems of young plants, which can cause additional harm. When the eggs hatch, the nymphs burrow into the soil where they can live for several years before returning to the surface to become adults. This lengthy life cycle means that their impact on gardens can be prolonged, making it essential for gardeners to employ effective protective measures when these insects are prevalent.
What strategies can I use to protect my garden from cicadas?
There are several effective strategies to protect your garden from cicadas. One of the most practical approaches is to use physical barriers, such as netting or row covers, to shield your plants from adult cicadas. Make sure to select a mesh with holes small enough to prevent cicadas from accessing your flowers and young plants, but large enough to allow sunlight and rain to nourish them.
Additionally, timely application of organic pesticides can help deter cicadas from your garden. Look for products containing neem oil or insecticidal soap, which are less harmful to beneficial insects and the environment while effectively managing cicada populations. Remember to follow application guidelines carefully to ensure maximum effectiveness and safety.
When is the best time to implement protection against cicadas?
The best time to implement protection against cicadas is prior to their emergence. Typically, cicadas begin to surface in late spring or early summer, so it’s wise to prepare your garden with barriers and treatments a few weeks beforehand. Monitoring local reports about cicada emergence can help you pinpoint the right time to start your protective measures.
Once cicadas start appearing, they will continue to mate and lay eggs over several weeks. It’s crucial to keep barriers in place and to monitor your plants regularly throughout this period. Depending on the species and local climate, the cicada season may vary, so staying informed will help you take proactive steps for your garden’s protection.
How do I identify plants at risk from cicadas?
Identifying plants at risk from cicadas is essential for targeting your protective measures effectively. Cicadas prefer young trees and shrubs with soft, succulent stems, as these are easier for them to penetrate to feed and lay eggs. Common targets include fruit trees, roses, and young ornamental plants. Look for signs of cicada activity, such as the characteristic “slit” marks on stems where females have laid their eggs.
Additionally, keep an eye out for wilting or yellowing leaves—these may indicate damage from sap feeding. If observed, it’s best to inspect the plant closely for evidence of egg-laying or nymph presence. Early identification enables gardeners to take timely action to safeguard their plants and minimize potential damage.
Can traps be used to control cicada populations?
Yes, traps can be utilized as part of a broader strategy to control cicada populations in your garden. Commercial traps are available that attract and capture cicadas using pheromones or light. These traps can be strategically placed near your plants to reduce the number of cicadas feeding on them. However, it’s essential to position them correctly to maximize their effectiveness and prevent unintended capture of beneficial insects.
While traps can help reduce the population of cicadas in a localized area, they should not be solely relied upon. Combining traps with other protective strategies, such as barriers and timely use of natural pesticides, will yield better results in safeguarding your garden from cicadas’ adverse effects.
Are there any natural predators of cicadas that can help control their numbers?
Yes, there are various natural predators of cicadas that can assist in controlling their populations. Birds, for example, are among the biggest consumers of cicadas when they emerge. Species such as robins, sparrows, and blue jays often feast on cicadas, helping to reduce their numbers in gardens. Planting bird-friendly trees and shrubs can encourage these natural predators to frequent your garden.
Moreover, certain insects, such as wasps and some beetles, also prey on cicadas. By fostering a healthy ecosystem in your garden that includes these beneficial insects and birds, you can create a balanced environment that naturally minimizes cicada populations over time. Avoid using broad-spectrum insecticides, as these can harm both beneficial predators and cicadas indiscriminately.
What to do if cicadas have already infested my garden?
If cicadas have already infested your garden, don’t panic; there are still steps you can take to mitigate their impact. First, assess the level of infestation and identify which plants are most affected. For heavily infested plants, consider using protective barriers such as netting or fabric to limit further access while allowing existing plants to survive the infestation period.
Additionally, removing and discarding any damaged plant parts can help shift the focus away from infested areas, allowing healthy parts to recover. Applying organic pesticides can provide a secondary line of defense by deterring further feeding. Be sure to monitor your garden regularly to adapt your strategy as needed and to prepare for any future cicada cycles.
Is it possible to completely eliminate cicadas from my garden?
Completely eliminating cicadas from your garden is highly improbable due to their life cycle and the fact that they emerge in large, synchronized swarms. Instead of aiming for total eradication, focus on management strategies that minimize their impact on your plants. Implementing protective barriers, utilizing natural predators, and applying organic control measures can help reduce the damage cicadas inflict on your garden without attempting to eliminate them entirely.
By creating a holistic garden management plan that combines various methods, not only will you protect your plants during cicada season, but you’ll also foster a more resilient garden ecosystem. Accepting that cicadas are part of a natural cycle can help gardeners adapt and find effective ways to coexist with them while maintaining healthy plants.
