Understanding Cicada Behavior

‍

When do cicadas emerge, and what drives their behavior? Cicadas appear mainly in late spring to early summer, when soil temperatures reach about 64°F (18°C). You'll notice them in cycles, as some species emerge every 13 or 17 years, while others appear annually. Their behavior is largely driven by their life cycle. They spend most of their lives underground as nymphs, feeding on plant roots. Once matured, they surface to molt, mate, and lay eggs, ensuring the continuation of their species.

‍

Understanding their behavior helps you manage their presence. When cicadas emerge, they can be incredibly noisy due to the males singing to attract mates. This is a natural part of their reproductive process. Keep in mind that cicadas are not harmful to humans or pets, but they can damage young trees and shrubs when laying eggs. They do so by slitting into thin branches to deposit eggs, which may lead to "flagging," or dieback of the branches.

‍

To minimize their impact, focus on protecting vulnerable plants and maintaining your garden. By understanding cicada behavior, you'll better prepare for their next emergence and mitigate potential issues.

Identifying Cicada Species

‍

Identifying cicada species can feel like a challenging task, but it doesn't have to be. Begin by examining their size and color. Cicadas typically range from 1 to 2 inches long. Annual cicadas, like the "dog-day" variety, are usually green with black markings, while periodical cicadas, like the Magicicada, have striking red eyes and orange-veined wings. Listen closely to their calls. Each species produces a unique sound. Annual cicadas emit a continuous, buzzing drone, while periodical cicadas produce a rhythmic, high-pitched song.

‍

Next, consider the timing of their emergence. Annual cicadas appear every summer, while periodical cicadas emerge in large numbers every 13 or 17 years, depending on the brood. Look around at the environment, too. Different species prefer specific habitats. Annual cicadas thrive in urban, suburban, and rural areas, whereas periodical cicadas often favor wooded regions.

Timing Your Control Efforts

‍

Understanding the different species of cicadas is just the first step in managing their presence effectively. Once you've identified the type, timing your control efforts becomes essential. Cicadas follow specific life cycles, and knowing when they emerge can make all the difference. Typically, cicadas appear during the warmer months, so you'll want to start your efforts before they become a full-blown nuisance.

‍

Begin by monitoring local predictions and reports on cicada emergence. Keep an eye on the weather; cicadas thrive in warm, moist conditions. Early spring is usually the best time to prepare, as this is when they start emerging from the ground. By acting before they appear, you can implement preventive measures and reduce their impact.

‍

If you wait until cicadas are already active, your options might be limited. Addressing them early can help protect your plants and trees from damage, as cicadas lay eggs in tree branches. Timing is everything, so plan to apply any treatments or barriers just as the nymphs are emerging. This proactive approach allows you to tackle the problem head-on and minimizes the chance of a cicada invasion in your garden or yard.

‍

Natural Repellents

‍

Curious about how you can naturally repel cicadas from your garden? You don't need harsh chemicals to keep these noisy bugs at bay. Try essential oils like peppermint, which cicadas find unpleasant. Mix a few drops of peppermint oil with water in a spray bottle and apply it to plants and garden surfaces. This creates a scent barrier that cicadas tend to avoid.

‍

Garlic is another effective natural repellent. Crush a few cloves and let them steep in water overnight. Strain the mixture and add it to a spray bottle. Spraying this garlic water around your garden deters cicadas with its strong odor. For an added boost, plant garlic or onions in your garden beds. These plants naturally repel pests, including cicadas.

‍

Cicadas also dislike vinegar. Mix equal parts of water and vinegar, then spray it onto trees and shrubs. This solution can help keep cicadas from settling in. Be cautious, as vinegar can damage some plants if used excessively.

‍

Finally, encourage natural predators like birds, who love feasting on cicadas. Install bird feeders or birdbaths to attract them, promoting a natural balance in your garden.

‍

Protective Netting

‍

To effectively keep cicadas away from your plants, consider using protective netting. This method creates a physical barrier, preventing cicadas from reaching tender branches and foliage. Choose a fine mesh netting with holes small enough to block cicadas, typically around 1/4 inch or less, ensuring they can't squeeze through. When selecting netting, opt for durable materials like nylon or polyethylene, which withstand weather conditions and provide long-lasting protection.

‍

Begin by draping the netting over your plants before the cicada emergence period, usually late spring or early summer. Secure the edges with stakes or weights to keep the netting in place and prevent cicadas from entering from below. Make sure the netting doesn't rest directly on the plants, as cicadas could still reach them. Use supports to create a tent-like structure, giving your plants room to grow without interference.

Physical Removal Techniques

‍

Tackling cicadas directly through physical removal techniques can be an effective way to protect your plants. Start by inspecting your garden regularly. Early detection helps you manage the problem before it escalates. Grab a pair of gloves and a bucket of soapy water. The soap helps to kill the cicadas quickly. Remove them from your plants by hand and drop them into the bucket. This method is straightforward and doesn't require special tools or chemicals.

‍

Another practical approach is using a garden hose with a strong spray nozzle. Spray water on your plants to dislodge cicadas. This method is especially useful for larger infestations. Once they're knocked off, you can collect them and dispose of them in the soapy water. Remember to check under leaves and in tree branches, as these areas can harbor hidden cicadas.

‍

In addition, consider using a handheld vacuum. This tool can suck up cicadas efficiently, especially for those hard-to-reach spots. After vacuuming, empty the contents into your soapy water mixture. These physical removal techniques are environmentally friendly and allow you to manage cicadas without harming beneficial insects or using pesticides.

Predators as Control

‍

Among nature's solutions to controlling cicada populations are their natural predators. Encouraging these predators in your area can help reduce cicada numbers effectively. Birds are one of the most common cicada predators. You can attract them to your garden by installing bird feeders and birdbaths. Consider planting shrubs and trees that provide shelter and nesting sites for these feathered friends.

‍

Bats also play a significant role in controlling cicadas, especially during nighttime when they're most active. By installing bat houses, you can create a welcoming environment for these nocturnal creatures, which in turn helps keep cicada populations in check.

‍

In addition to birds and bats, you might find some help from small mammals like squirrels and chipmunks, which occasionally consume cicadas. Encouraging a diverse ecosystem in your yard can naturally attract these animals.

‍

Don't forget about predatory insects and arachnids. Wasps, spiders, and praying mantises can all help control cicadas. To attract these beneficial insects, consider planting native flowering plants that provide nectar and pollen.

‍

Sound Barriers

‍

While natural predators offer a way to keep cicada numbers in check, you can also consider sound barriers as a practical approach. Cicadas are notorious for their loud mating calls, which can reach up to 100 decibels. By using sound barriers, you can reduce the noise and even deter these insects from settling in your area.

‍

Start by identifying the areas where cicadas are most active, typically in trees or shrubs. Erecting barriers like dense hedges or fences can help absorb and block sound. Consider using materials that have sound-dampening properties, such as thick fabrics or acoustic panels. These can be strategically placed around your yard to create a quieter environment.

‍

Additionally, white noise machines or outdoor speakers playing low-frequency sounds can mask cicada calls. These devices can be installed discreetly in your garden or patio, providing a peaceful ambiance.

‍

Keep in mind that cicadas are attracted to vibrations, so reducing noise can make your space less appealing to them. Regularly check and maintain your sound barriers to guarantee effectiveness. This proactive approach helps you enjoy a more serene outdoor experience during cicada season.

‍

Chemical Treatments

‍

Chemical treatments offer a direct method to control cicada populations effectively. By using insecticides, you can target cicadas during their active phases. Start by selecting a suitable insecticide labeled for cicada control. Pyrethroids, such as permethrin or bifenthrin, are commonly used and can be found at garden centers. They work by disrupting the nervous system of the insects, leading to their eventual death.

‍

When applying, wear protective gear like gloves and a mask, and follow the manufacturer's instructions to guarantee safety and effectiveness. Focus on treating areas where cicadas are most active, such as trees, shrubs, and garden beds. Apply the insecticide early in the morning or late in the evening when cicadas are less active, ensuring better contact.

‍

Long-term Prevention Strategies

‍

To keep cicadas at bay in the long run, focus on implementing preventative measures that minimize their attraction and breeding opportunities. Start by maintaining your yard; regularly trim trees and shrubs to reduce shady areas where cicadas might lay eggs. Removing excess branches also limits the potential for cicada damage. Consider planting cicada-resistant trees like birch, dogwood, or oak, as these species tend to be less appealing to them.

‍

Next, protect young trees by wrapping their trunks with fine mesh netting during peak cicada season. This prevents cicadas from reaching branches and laying eggs. Verify the netting is tightly secured and covers the tree completely, especially the lower branches.

‍

Another effective strategy is to reduce outdoor lighting, particularly at night. Cicadas, like many insects, are drawn to light. Using motion sensors or simply switching off unnecessary lights can deter them from settling in your yard.

‍

Finally, encourage natural predators such as birds and bats by creating a wildlife-friendly environment. Install birdhouses or bat boxes to attract these predators, which naturally help control cicada populations. By taking these steps, you'll create a less inviting space for cicadas, guaranteeing they don't become a long-term nuisance.

‍

Conclusion

‍

By understanding cicada behavior and identifying the species, you can time your control efforts effectively. Use natural repellents and protective netting to keep them at bay. Encourage predators to control their numbers, and consider sound barriers to disrupt their communication. If necessary, carefully apply chemical treatments. For long-term prevention, focus on maintaining your garden and landscape. With these proven techniques, you'll manage cicadas effectively, ensuring a peaceful and thriving outdoor environment.
