As the temperatures begin to rise and summer approaches, many gardeners start to prepare their plots for the growing season. However, one sound that often accompanies the warmth is the distinctive buzz of cicadas. These intriguing insects have a notorious reputation for their loud mating calls and, during specific cycles, their potential impact on plants. If you’re a gardener, you might be wondering: will the cicadas eat my garden? This article dives deep into this question, helping you understand cicadas’ role in our ecosystems and what you can do to protect your beloved plants.
What Are Cicadas?
Cicadas belong to the order Hemiptera and are known for their distinctive sounds produced by males in an effort to attract females during mating season. There are several species of cicadas, but the most famous ones include the annual cicadas (which emerge every year) and the periodical cicadas, which have a life cycle of 13 or 17 years, depending on their variety.
The Life Cycle of Cicadas
Understanding cicadas’ life cycle can provide insight into their behavior and presence in your garden. The cicada life cycle consists of several stages:
- Egg Stage: Female cicadas lay eggs in small slits they create in young tree branches. This can occur in the late spring or summer. The eggs hatch after a period of time.
- Nymph Stage: Once the eggs hatch, the nymphs drop to the ground, where they burrow and feed on plant roots for several years. This underground phase can last for 13 or 17 years, depending on the species.
- Adult Stage: After growing through various molting stages underground, the nymphs emerge from the soil, shedding their exoskeletons. This is when they become adults, ready to mate and produce the next generation, completing the cycle.
The Sounds of Cicadas
The male cicada has a specialized organ called a tymbal, which it uses to produce its loud mating call. The resonating sound usually signifies that adult cicadas are present, and while beautiful to some, others find it overwhelming.
Do Cicadas Eat Your Garden?
The pivotal question remains: will cicadas eat my garden? Thankfully, cicadas do not eat garden plants. Their main diet consists of the juices of roots, stems, and branches, which they obtain during their nymph stage underground.
The Real Threat to Your Garden
While cicadas do not consume your plants directly, there are some potential risks associated with their presence in your garden:
-
Egg-laying Damage: Female cicadas lay their eggs in the stems of plants. This process can cause physical damage to young trees and shrubs. The slits they make in the branches may create openings for pathogens, leading to diseases.
-
Nymph Activity: While underground, cicada nymphs can feed on the roots of plants. This feeding can weaken younger plants, making them more susceptible to stress and other threats.
Signs of Cicada Activity in Your Garden
Being proactive in identifying cicada activity can help you mitigate any potential harm to your plants. Here are a few signs to watch for:
- Sound: Listen for the distinctive buzzing call of male cicadas, especially in late spring and early summer.
- Egg-Laying Sites: Look for small slits in the branches of trees and shrubs, which indicate where females have laid eggs.
- Soft and Wilting Plants: If you notice plants wilting and lacking vigor, it could be a sign that nymphs are affecting the root system.
Protecting Your Garden from Cicadas
While cicadas do not feed on plants as adults, safeguarding your garden against their egg-laying habits is essential. Here are some strategies you can employ to protect your garden effectively:
Physical Barriers
- Netting: Use fine mesh netting or cloth to cover young trees and shrubs. This will prevent cicadas from laying eggs in their branches.

The Importance of Patience
Remember that cicadas come and go, and much like other pest cycles, they are a temporary presence in your garden. Be patient, and your plants can recover and flourish once again.
Conclusion
In summary, while cicadas do not directly consume your garden plants, their emergence can lead to certain challenges that require your attention. By employing protective measures and nurturing your garden after cicadas have passed, you can ensure that your plants remain healthy and vibrant throughout the growing season. With a deeper understanding of cicadas and their behavior, you’ll be well-equipped to enjoy the beauty of summer without undue worry about these fascinating insects.
What are cicadas, and how do they differ from other insects?
Cicadas are large, flying insects known for their distinctive sound produced by males to attract females. They belong to the order Hemiptera and the family Cicadidae. Unlike crickets or grasshoppers, which produce sounds through stridulation, cicadas create their calls using specialized membranes called tymbals. There are various species of cicadas, some of which have short life cycles of a few years, while others emerge in cycles of 13 to 17 years.
These insects have a unique lifestyle, spending most of their lives underground as nymphs before emerging in a synchronized event to mate and reproduce. Their life cycle includes a lengthy juvenile phase, which is essential for their growth and development, and a brief adult phase, where their primary focus is reproduction. This cyclical emergence can lead some people to be confused about their life stages and behavior.
How do cicadas affect garden plants?
Cicadas can have both positive and negative impacts on garden plants. On the negative side, female cicadas lay their eggs in the stems of young branches, which can cause damage to the plant. When they insert their eggs, it may lead to split stems, and if there are numerous cicadas, this can affect the plant’s overall health and yield. Young and tender plants are particularly vulnerable, and this damage may stunt growth or lead to death.
On the positive side, cicadas can benefit soil health. When cicada nymphs emerge from the ground, their tunneling helps aerate the soil. This aeration can enhance root development and improve water drainage, benefiting the surrounding plants. Moreover, as cicadas die off after their short adult lifespan, they provide a source of organic matter and nutrients that can enrich the soil for other plants.
Are cicadas beneficial for the ecosystem?
Yes, cicadas play a significant role in the ecosystem. As herbivores, they feed on sap from trees and plants, but their feeding habits typically do not cause severe damage to mature trees. In fact, their presence can help support various wildlife. Birds, bats, and other predators rely on cicadas as a vital food source during their short emergence period. This provides an abundance of nutrition for these animals, making cicadas an essential part of the food web.
Additionally, cicadas aid in nutrient cycling. Their decaying bodies after they die contribute organic matter to the soil, enhancing its fertility. The nutrient-rich material promotes healthy plant growth and supports the overall biodiversity of the garden. Consequently, while they may seem like a nuisance, cicadas contribute positively to ecological balance and health.
How do I protect my garden from cicadas?
To protect your garden, you can employ various methods. One effective approach is to cover young plants with protective netting or mesh to prevent cicadas from accessing them for egg-laying. Ensure the material is fine enough to keep out cicadas but allows light and air to reach the plants. Monitoring your garden closely during cicada emergence is crucial, as early intervention can reduce potential damage.
Another strategy is to foster a diverse ecosystem in your garden. Planting a variety of plants can attract beneficial insects and birds that help deter cicadas. Additionally, maintaining healthy soil and plant practices, such as mulching and regular watering, ensures your plants are robust enough to withstand cicada activity. With these preventive measures, you can minimize the impact of cicadas on your garden.
What should I do if my garden is damaged by cicadas?
If you notice damage in your garden due to cicadas, it’s essential to act quickly. First, assess the extent of the damage. If young plants show stem splitting or wilting, you can prune away affected branches to promote healthy growth. This pruning also reduces the likelihood of fungal diseases that may result from the wounds created by cicadas. Keeping the plants well-watered and healthy post-damage will support recovery.
Additionally, consider applying a balanced fertilizer to nourish your plants, as they may need an extra boost after significant stress. Monitoring your garden for any signs of secondary pests that may take advantage of the damaged areas is also vital. Regularly checking for new growth will help determine if the plants can recover, and in many cases, they can bounce back quickly with the right care.
Can cicadas be harmful to human health?
Cicadas are generally not harmful to human health. They do not sting, bite, or transmit diseases to humans, making them safe to be around. However, their loud mating calls can be disruptive in large numbers, particularly during their peak emergence periods. Some individuals may find the sound bothersome, but it is not a health hazard and usually subsides after a short period as the cicadas complete their life cycle.
In rare instances, allergies to cicada parts or their shed exoskeletons may occur, particularly for individuals with sensitivities to insects. If you have a known insect allergy, it’s wise to avoid direct contact with cicadas and area where they are prevalent. Overall, while cicadas can be noisy and occasionally messy, they pose little threat to human health and safety.
Do cicadas have any economic impact?
Cicadas can have an economic impact, primarily through their effects on agriculture. For home gardeners and commercial growers, heavy cicada infestations can lead to damage in young crops, specifically fruit, and ornamental plants. This damage may translate to financial loss, especially if the plants fail to produce or require replacement. Increased vigilance and protective measures can help mitigate these financial risks, but they may incur additional costs for gardeners.
Conversely, cicadas can also have positive economic implications. Their emergence can attract visitors to areas where they are prevalent, boosting tourism in certain regions. Festivals and events centered around cicadas offer opportunities for local businesses to capitalize on their uniqueness. Additionally, the nutrient cycling provided by cicadas contributes to healthier soil and potentially higher yields in the long term, benefiting agriculture in a more indirect economic sense.
When do cicadas typically emerge?
The emergence of cicadas can vary based on the species. Periodical cicadas, which follow a distinct 13 or 17-year life cycle, typically emerge in late spring to early summer. Their emergence is synchronized, and they can blanket areas, leading to large populations appearing at once. The specific timing of their emergence is heavily influenced by temperature and soil conditions; warm, moist conditions signal that it’s time for the nymphs to surface.
In contrast, annual cicadas emerge every year but may have staggered emergence times. They often appear later in the summer months, with adults calling from trees throughout July and August. Regardless of the type, cicadas are most active during warm weather, taking advantage of the conditions to mate and complete their life cycle before returning to the ground.
