If you’ve ever experienced a cicada invasion, you know how disruptive it can be to your garden’s beauty and productivity. As these loud and persistent insects emerge in droves, they can wreak havoc on plants, particularly young seedlings and fruit-bearing trees. However, with the right strategies, you can protect your garden and ensure it thrives. In this article, we’ll explore effective methods for keeping cicadas out of your garden, safeguarding your plants, and maintaining a serene outdoor space.
Understanding Cicadas and Their Lifecycle
To effectively keep cicadas at bay, it’s essential to understand their lifecycle:
The Cicada Lifecycle
Cicadas are renowned for their unique lifecycle, consisting of larval, nymph, and adult stages. The majority of cicada species emerge every 13 or 17 years, but annual cicadas appear each summer.
- Nymph Stage: Cicada nymphs live underground for several years, feeding on the sap of plant roots.
- Emergence: When the temperature warms, they emerge from the soil, molting into their adult form. This stage is where they cause the most damage to gardens.
- Mating and Egg-Laying: After mating, females lay eggs in the branches of trees and plants, which can eventually lead to more nymphs burrowing underground.
Understanding this lifecycle is crucial for timing your preventive measures.
Why Cicadas Can Be Destructive
Cicadas are primarily known for their loud calls, but their voracious appetite for sap can be damaging. Here’s how they can be particularly harmful to your garden:
1. Sap Feeding
Cicadas feed by inserting their beak-like mouthparts into plant tissue, extracting sap. This feeding can weaken plants, causing wilting, stunted growth, and even death in severe cases.
2. Egg-Laying Damage
Female cicadas create slits in branches to lay their eggs, which can lead to dieback and potentially open wounds susceptible to diseases.
3. Noisy Environment
While not a direct threat to plants, the overwhelming noise of cicada calls can detract from your gardening experience, making it difficult to enjoy a peaceful environment.
Effective Strategies to Keep Cicadas Out of Your Garden
To protect your garden from cicadas, consider employing a combination of several strategies. Here are some effective methods:

Know When to Expect Cicadas
Research the specific cicada species present in your region. If you live in an area where periodic cicadas emerge, prepare your garden in advance. Preparation might involve timing planting schedules to avoid exposure during peak cicada seasons.
2. Physical Barriers
Using barriers is one of the most straightforward ways to keep cicadas away from your plants.
Netting and Screens
Cover your plants with fine mesh netting that allows sunlight and rain but keeps cicadas out. This method works exceptionally well for young seedlings and fruit-bearing plants. Ensure the netting is secured tightly to prevent any cicada entry.
Row Covers
Lightweight row covers can also provide protection for crops. These covers can help maintain the right temperature for plants while keeping unwanted pests like cicadas away.
3. Traps and Repellents
While not always the most effective, using traps and natural repellents can provide additional protection.
Cicada Traps
You can create homemade traps using simple materials such as sugar water or beer in a shallow dish to lure cicadas. Place these traps strategically around your garden to catch any cicadas before they can reach your plants.
Natural Repellents
Certain plants, such as marigolds and mint, can naturally repel cicadas due to their scent. Planting these around your garden can help deter cicadas while adding beauty and scent to your outdoor space.
4. Landscape Management
Effective landscape management can reduce cicada populations in your garden.
Avoiding Attractive Plant Varieties
Some plants are more attractive to cicadas than others. Focus on planting varieties that are less susceptible to cicada feeding.
Regular Maintenance
Taking care of your garden by regularly trimming branches and cleaning up debris can help eliminate potential nesting sites for cicadas. Promptly remove egg-laden branches, as cicada eggs can survive through the next season.
5. Encourage Beneficial Insects
Creating a balanced ecosystem can naturally keep cicada populations in check.
Beneficial Predators
Encouraging predatory insects such as spiders and birds can help keep cicadas under control. Plant flowering plants that attract these beneficial insects, which can naturally decrease the number of cicadas in your garden.
6. Chemical Control Methods
While typically a last resort, chemical treatments can be effective when dealing with severe cicada populations.
Insecticides
If cicadas become a perennial problem and physical barriers or natural methods prove insufficient, you may consider insecticides labeled for cicada control. Always read the label carefully to ensure safety for other beneficial insects and your plants.
After the Cicadas: Protecting Your Garden
Once the cicadas have left your garden, the work isn’t over. Here are some steps to take to ensure your plants rebound effectively.
1. Inspect and Prune
After cicada season, inspect your plants for damage, including dead branches or egg-laying sites. Prune as necessary to promote healthy growth.
2. Fertilize and Water
Providing nutrients and adequate water can help your plants recover from any stress caused by cicadas. Choose a balanced fertilizer suitable for the specific plants in your garden.
Conclusion
Keeping cicadas out of your garden requires a proactive and multifaceted approach. By understanding their lifecycle, employing physical barriers, and managing your landscape effectively, you can create a cicada-free haven for your plants. Remember that a little prevention goes a long way, and your efforts will result in a thriving garden that you can enjoy season after season. With persistence and the right strategies, you’ll be able to enjoy the harmony of your outdoor space, free from the disruptions of cicada invasions.
What are cicadas and why are they a problem for gardens?
Cicadas are large, flying insects known for their distinctive buzzing sound, which they produce during their mating season. While they are not harmful to humans, cicadas can pose a significant threat to gardens as the females lay their eggs in the stems of young plants, causing damage that may lead to plant stress or even death. Their feeding habits can also weaken plants, making them more susceptible to diseases or pests.
In addition to their direct impact on plants, cicadas can also attract other predators, including birds that may further damage your garden. For these reasons, gardeners must take proactive measures to protect their plants from cicadas to ensure a healthy and thriving garden environment.
How can I identify cicadas in my garden?
Cicadas are easily recognizable due to their large size, generally ranging from 1 to 2 inches in length. They have prominent eyes, short antennae, and transparent wings that usually stretch out to the sides when at rest. Typically, cicadas are brown, green, or black, which can help camouflage them in their natural environment. Listening for their loud, distinctive calls during the mating season is another effective way to identify their presence.
Moreover, cicadas leave behind unique egg-laying scars on tree branches, characterized by small slits or cuts where females have deposited their eggs. These signs can be a clear indication of cicadas in your garden, prompting you to take action to protect your plants from potential damage.
What natural methods can I use to deter cicadas?
One of the most effective natural methods to deter cicadas is to create a disruptive environment. This can be done by planting companion plants that cicadas dislike, such as garlic or certain herbs, which can mask the scent of desirable plants, making them less appealing. Additionally, introducing beneficial insects that prey on cicadas, such as parasitic wasps, can help keep the cicada population in check without the need for chemical pesticides.
Another natural strategy is to ensure that your garden is well maintained and free from excessive debris. Keeping the area tidy can remove potential nesting sites for cicadas, while also promoting the health of your plants, making them less attractive targets. Regularly monitoring your garden and promptly removing any infested plants can also minimize the impact of cicadas.
Is there a way to create barriers against cicadas?
Yes, creating physical barriers is one of the most effective methods to keep cicadas out of your garden. Using fine mesh netting or insect exclusion fabric can help cover vulnerable plants and prevent cicadas from reaching them to lay eggs. Ensure the netting is securely anchored at the base to prevent any gaps through which cicadas can enter.
In addition to netting, consider surrounding your garden with circular barriers made from materials like perimeter fencing or row covers. These barriers will deter cicadas while still allowing light and moisture to reach your plants. Ensuring that these barriers are properly installed is essential for maximizing their effectiveness against cicada invasions.
How can I maintain a healthy garden to resist cicadas?
Maintaining a healthy garden involves several key practices that not only promote plant health but also help minimize cicada threats. Regularly watering your plants ensures they remain vigorous and resilient, making them less susceptible to damage from cicadas. Fertilizing appropriately and providing adequate sunlight will also support strong plant growth, reducing the chances of cicadas causing significant harm.
Additionally, implementing proper pest management techniques, such as crop rotation and companion planting, can enhance your garden’s natural defenses. Keeping an eye out for signs of cicada presence and addressing potential problems early can help keep your garden thriving while minimizing the risk posed by these insects.
What chemical methods are available to control cicadas?
If natural methods do not suffice, there are chemical options available for cicada control, though they should be used as a last resort to minimize environmental impact. Insecticides containing ingredients like carbaryl or permethrin can be effective when applied directly to plants during cicada emergence. However, timing is crucial; applying these treatments just before cicadas begin to emerge can improve their efficacy.
It’s essential to follow label instructions carefully when using pesticides, as improper application can harm beneficial insects and the overall ecosystem. Additionally, consider selecting products specifically designed for cicadas, as they tend to have less impact on non-target species and the surrounding environment when used correctly.
When is the best time to implement cicada control methods?
The best time to implement cicada control methods typically aligns with their life cycle, primarily during the spring and early summer months when they emerge. This is usually when adult cicadas begin to appear and start mating, making it a critical period for your interventions. Monitoring local cicada emergence reports can provide guidance on when to be proactive in your garden.
Implementing control measures as soon as you notice cicadas or their signs can significantly increase the success of deterring them. Regularly checking your garden throughout the cicada season will help you stay one step ahead in protecting your plants from these invasive insects.
