Natural Remedies for Deterring Unwanted Red-Eyed Cicadas

Red-eyed cicadas, known for their distinctive crimson eyes and loud summer chorus, can sometimes become an unwelcome presence in gardens and outdoor spaces. While these insects play an important role in the ecosystem, their sheer numbers and noisy behavior can be bothersome to homeowners and gardeners. Fortunately, there are a variety of natural remedies available to help deter unwanted red-eyed cicadas without harming the environment or beneficial insects. This article explores effective, eco-friendly strategies to keep these insects at bay.

Understanding Red-Eyed Cicadas

Before diving into remedies, it’s useful to understand the characteristics of red-eyed cicadas that make them both fascinating and occasionally troublesome:

• Appearance: These cicadas have distinctive red eyes, transparent wings with visible veins, and robust bodies.
• Behavior: They are most active during late spring and summer, often heard rather than seen due to their loud mating calls.
• Lifecycle: Cicadas spend years underground as nymphs before emerging en masse as adults to mate and lay eggs.
• Ecological Role: They aerate soil during their nymph stage and serve as food for birds and other wildlife.

However, when large numbers gather on trees or structures around homes, they can cause damage by laying eggs in twigs and creating an overwhelming noise disturbance.

Why Choose Natural Remedies?

Commercial pesticides may seem like a quick fix but often pose risks to pollinators like bees, beneficial insects, pets, and even humans. Natural methods provide a safer, sustainable solution that balances pest control with environmental health.

Natural Remedies to Deter Red-Eyed Cicadas

1. Encourage Natural Predators

One of the most effective ways to manage cicada populations is through supporting their natural enemies:

• Birds: Many bird species feed on cicadas. Installing bird feeders or birdhouses can attract insectivorous birds to your garden.
• Wasps and Spiders: Certain wasp species parasitize cicada eggs or larvae. Creating habitats that encourage wasps (while managing stings risk) can naturally reduce cicada numbers.
• Small Mammals: Animals like squirrels sometimes prey on cicadas.

By fostering biodiversity in your yard with native plants and water sources, you invite these predators to help keep cicada populations under control.

2. Plant Cicada-Repellent Plants

Certain plants naturally repel cicadas due to their scent or chemical properties. Incorporate these into your landscaping near vulnerable trees or resting places:

• Garlic: The strong odor of garlic is offensive to many insects including cicadas.
• Chrysanthemums: Contain pyrethrins, natural insect repellents.
• Lavender: Its aromatic oils deter various pests.
• Marigolds: Known for repelling many garden pests.

Planting these species along borders or near trees can discourage cicadas from settling nearby.

3. Use Homemade Organic Sprays

Natural sprays made from common household ingredients can be applied directly on plants to deter cicadas:

• Garlic Spray: Blend several cloves of garlic with water, strain, and spray on affected trees.
• Neem Oil: Extracted from the neem tree seeds, neem oil disrupts insect feeding and reproduction without harming beneficial bugs.
• Soap Spray: Mix mild liquid soap with water (about 2 tablespoons per gallon) and spray on foliage. This can suffocate soft-bodied insects without toxic residues.

Apply sprays in early morning or late evening to avoid leaf burn and reapply after rain for effectiveness.

4. Physical Barriers

Creating physical obstacles prevents cicadas from accessing plants where they lay eggs:

• Netting: Use fine mesh nets (such as horticultural fleece) over small trees or shrubs during peak emergence periods.
• Tree Wrapping: Wrap trunk bases with sticky bands or protective wraps to stop nymphs climbing up.

Ensure barriers do not trap other wildlife unintentionally; remove after the cicada season passes.

5. Maintain Healthy Trees

Strong, well-watered trees are less vulnerable to damage from egg-laying cicadas:

• Regular watering during drought stress helps trees resist bark splitting caused by egg insertion.
• Prune weak branches which are preferred sites for female cicadas to lay eggs.
• Mulching conserves soil moisture and promotes root health.

Healthy trees can better tolerate some degree of cicada activity.

6. Timely Raking and Disposal

Since cicada nymphs emerge from the soil, managing ground conditions helps reduce future populations:

• Rake up fallen leaves, twigs, and debris where nymphs may hide.
• Remove egg-laden branches by pruning during late summer after adult activity subsides.
• Dispose of collected material away from your property to prevent reinfestation.

This mechanical control method reduces the number of emerging adults the following year.

7. Noise Disruption Techniques

While sound-based methods have limited scientific backing against cicadas’ noisy calls themselves, minimizing attractants that lure them toward specific areas is useful:

• Turn off outdoor lights at night since bright lights can attract some insect species.
• Use white noise machines in patios or porches if noise disturbance is a serious concern indoors.

These mild interventions can help make your immediate vicinity less appealing without distressing wildlife.

Timing Is Key

Cicada infestations are typically seasonal—emerging en masse every 13 or 17 years depending on species. Knowing local emergence schedules allows you to prepare ahead with preventive measures such as netting young trees or boosting natural predator habitats well before peak activity.

Benefits of Embracing Cicadas

While deterring unwanted red-eyed cicadas is understandable, remember they have ecological benefits:

• They improve soil aeration during subterranean stages.
• Provide a food source for many animals.
• Their decaying bodies enrich soil nutrients post lifecycle.

Using gentle deterrents rather than eradication preserves this balance in nature while protecting your garden’s health.

Conclusion

Managing red-eyed cicadas naturally involves a combination of encouraging predators, planting repellent species, applying organic sprays, using physical barriers, supporting tree health, maintaining cleanliness outdoors, and understanding their lifecycle timing. These eco-friendly approaches allow you to minimize damage and disturbances caused by these fascinating insects without resorting to harmful chemicals. With patience and integrated care strategies, you can enjoy your outdoor spaces peacefully throughout the buzzing season while respecting nature’s rhythms.
