Cicadas are fascinating creatures that can command attention with their noteworthy sounds and unique life cycle. However, when it comes to gardening, these buzzing insects can become a nuisance, especially during their mating season. They can cause significant damage to tender plants, vegetables, and fruit trees. In this comprehensive guide, we will explore various methods to keep cicadas at bay, ensuring your garden thrives while maintaining a peaceful atmosphere.
Understanding Cicadas: The Basics
Before diving into the strategies for cicada management, it is essential to understand what cicadas are and how they behave. Cicadas belong to the order Hemiptera and are known for their loud mating calls. There are numerous species of cicadas, with the periodical cicada being one of the most notable due to its 13 or 17-year life cycle.
The Life Cycle of Cicadas
Cicadas have a unique life cycle consisting of three main stages: egg, nymph, and adult.
- Egg Stage: Female cicadas lay eggs in tree branches, causing sap to ooze, which can damage the tree.
- Nymph Stage: After hatching, nymphs drop to the ground and burrow into the soil, where they begin their long underground phase, feeding on tree roots.
- Adult Stage: After several years, nymphs emerge from the ground, molt into adults, and begin the cycle anew.
Understanding this cycle can aid in devising effective strategies to combat their presence in your garden.
Prevention Starts at the Source
One of the best ways to keep cicadas away from your garden is to prevent them from settling in the first place. There are several tactics you can employ to achieve this.

The key to your garden’s health lies in vigilance and proactive measures. With determination and the right strategies, you can keep cicadas at bay, enabling your plants to thrive in a serene and flourished environment. Cultivating an understanding of cicadas’ behavior and needs is the first step toward gardening success without the constant buzz of cicada interference.
What are cicadas and why are they a problem for gardens?
Cicadas are large, flying insects known for their distinctive buzzing sounds, primarily produced by males during mating calls. They belong to the family Cicadidae and can be found in many parts of the world. While adult cicadas do not typically damage plants, their nymphs feed on the roots of various plants, which can lead to stunted growth and potential death of younger or weaker plants. During peak seasons, swarms of cicadas can also overwhelm gardens, creating noise and attracting other pests.
In addition to the potential harm caused by nymphs feeding on roots, cicadas can pose a particular threat to newly planted trees and shrubs. Female cicadas lay their eggs in slits they cut into tree branches, which can cause injury and make plants susceptible to infections. Thus, managing cicada populations is essential for maintaining the health and vitality of your garden.
How can I make my garden less attractive to cicadas?
To make your garden less attractive to cicadas, it’s important to create an environment that encourages beneficial insects while deterring cicadas.
