Tips for Minimizing Noise Caused by 17-Year Periodical Cicada Swarms

Every 17 years, certain regions in North America are visited by an extraordinary natural phenomenon: the emergence of periodical cicadas. These insects, famous for their synchronized appearance and intense noise, can create a cacophony that lasts for several weeks. While cicadas play an important role in the ecosystem, their overwhelming noise can be a challenge, particularly for residents, schools, and businesses in affected areas.

In this article, we explore effective tips and strategies to minimize the noise caused by 17-year periodical cicada swarms. Whether you’re looking for temporary relief or long-term solutions, these insights will help you create a more peaceful environment during cicada season.

Understanding 17-Year Periodical Cicadas

Periodical cicadas are unique insects that spend most of their lives underground as nymphs for 17 years before emerging en masse to mate and lay eggs. Their synchronized emergence leads to large swarms with millions of individuals per acre in some areas. Male cicadas produce loud mating calls by vibrating membranes called tymbals on their abdomens, reaching sound levels up to 100 decibels.

The noise can start at dawn and continue until dusk for several weeks, often peaking during the hottest parts of the day. The intensity of the noise is not only disruptive to human activities but can also be stressful for pets and wildlife.

Why Minimize Cicada Noise?

While cicadas are a natural and temporary event, minimizing their noise is important because:

• Improves Quality of Life: Continuous loud noise can cause headaches, irritability, and difficulty concentrating.
• Enhances Productivity: Students and employees may struggle to focus during outdoor activities or in environments without adequate soundproofing.
• Protects Pets: Some animals become anxious or stressed due to the persistent noise.
• Preserves Outdoor Enjoyment: Reduces disruption to gardening, recreational activities, or social gatherings.

Understanding these benefits helps motivate proactive measures to manage cicada noise effectively.

Tips for Minimizing Cicada Noise

1. Soundproof Your Living Space

Soundproofing is one of the most effective ways to block or reduce cicada noise indoors.

• Seal Gaps and Cracks: Use weatherstripping or caulk around windows and doors to prevent sound leakage.
• Install Double-Pane Windows: These significantly reduce outdoor noise penetration compared to single-pane.
• Use Heavy Curtains: Thick drapes made from dense fabrics can absorb sound waves.
• Add Rugs and Upholstery: Soft furnishings reduce echo inside rooms, lowering perceived noise levels.
• Consider Acoustic Panels: In severe cases, install acoustic foam panels on walls or ceilings to dampen sound.

Even small improvements in sealing and insulation can make a meaningful difference.

2. Create White Noise Buffers

Using white noise machines or fans can help mask cicada sounds by introducing a consistent background hum.

• White Noise Machines: Devices designed to produce soothing sounds like rain, ocean waves, or static can drown out irregular cicada calls.
• Fans or Air Conditioners: A running fan or AC unit generates ambient noise that helps cover up outdoor sounds.
• Music or Nature Sounds: Playing calming instrumental music or nature soundtracks inside can also provide distraction from cicadas.

This approach does not eliminate noise but makes it less intrusive by shifting auditory focus.

3. Limit Outdoor Exposure During Peak Hours

Cicadas tend to be most active and vocal during warm daylight hours, especially between late morning and mid-afternoon.

• Plan Activities Early or Late: Schedule outdoor work, exercise, or recreation during early morning or evening when cicada activity is lower.
• Stay Indoors During Peak Noise: If possible, avoid spending extended time outside during the loudest periods.
• Use Protective Headgear: For those who must be outdoors (e.g., gardeners), consider wearing earplugs or noise-cancelling headphones designed for outdoor use.

Adjusting your daily routine according to cicada activity patterns helps reduce direct exposure to intense noise.

4. Modify Landscaping Features

Cicadas tend to congregate on trees and shrubs where males sing to attract females. Altering your landscape can make your property less attractive to them.

• Prune Trees and Shrubs: Regularly trim branches where cicadas might rest or lay eggs.
• Remove Weak Branches: Cicadas prefer laying eggs on small twigs; removing damaged growth reduces egg-laying sites.
• Use Netting or Screens: Cover small trees with fine mesh netting during peak emergence periods.
• Limit Planting of Preferred Species: Some tree species are more prone to cicada infestation (e.g., oak, maple); avoid planting large numbers near living spaces if possible.

While landscaping changes won’t eliminate noise entirely, they reduce nearby cicada concentrations.

5. Use Natural Repellents Cautiously

There are no guaranteed chemical repellents specifically targeting periodical cicadas; however, some people use natural deterrents as part of integrated management:

• Garlic Spray: A mixture of garlic and water sprayed on plants may deter some insects.
• Neem Oil: Often used against other pests; its effect on cicadas is limited but may discourage feeding.

Note that these methods have mixed results and are more useful for preventing damage rather than reducing mating calls.

6. Educate Yourself and Neighbors

Community awareness helps everyone prepare for the periodic swarm:

• Inform Neighbors About Timing: Knowing when emergence will happen allows collective preparation.
• Share Mitigation Strategies: Exchange tips on soundproofing, timing activities, or landscaping.
• Coordinate Outdoor Events Carefully: Plan neighborhood events outside peak emergence years where possible.

Cooperation results in better overall management across neighborhoods rather than isolated efforts.

7. Consider Temporary Relocation if Necessary

For those extremely sensitive to loud noises, such as young children, elderly individuals, or people with certain health conditions, temporary relocation might be the best option:

• Spend peak swarm weeks with family outside affected areas.
• Book short-term accommodation elsewhere if work permits.

This solution is obviously more disruptive but can be considered in cases where mental well-being is significantly impacted.

Additional Tips for Businesses and Schools

Businesses and educational institutions in affected regions face unique challenges:

• Install Sound Barriers Outdoors: Temporary fences with sound-dampening materials can shield outdoor workspaces or playgrounds.
• Use Indoor Spaces More Frequently: Shift outdoor classes or meetings indoors during heavy swarm days.
• Provide Noise-Cancelling Headphones: Supply employees or students with headphones designed to reduce background noise.
• Communicate Transparently: Inform clients, students, or customers about potential disruptions so expectations are managed.

Planning ahead ensures minimal disruption to operations during cicada emergence years.

What Not To Do

Avoid ineffective or harmful practices such as:

• Using pesticides indiscriminately: This damages beneficial insects and the environment without controlling cicada populations meaningfully.
• Attempting physical removal: Given their huge numbers and short aboveground life span (4-6 weeks), manual removal is impractical.

Focus efforts instead on mitigating noise impact rather than eradication attempts.

Conclusion

The 17-year periodical cicada emergence is a spectacular natural event marked by loud swarming sounds that can disrupt daily life. While completely eliminating the noise is impossible without drastic measures, there are many practical steps homeowners, schools, businesses, and communities can take to minimize its impact.

From soundproofing indoor spaces and using white noise machines to modifying landscaping and scheduling activities strategically, these tips collectively help create a quieter environment during cicada season. By preparing ahead of time and adopting a combination of methods suited to your situation, you can protect your peace of mind while respecting this unique ecological phenomenon.

Embrace the cycle of nature with understanding and preparation, and find ways to coexist comfortably with the noisy yet fascinating periodical cicadas.
