In this article, we will provide you with valuable tips and strategies on how to control cicada populations and minimize their impact on your environment. By following these techniques, you can effectively manage cicada infestations and enjoy a quieter, more peaceful summer season.
Understanding Cicadas
Cicadas are fascinating insects known for their loud buzzing noise and distinctive life cycle. With over 3,000 different species worldwide, cicadas are mainly found in temperate regions, such as North America, where they emerge in large numbers during specific years. These buzzing insects spend most of their lives underground as nymphs, feeding on sap from tree roots.
What are Cicada Broods?
One of the most unique characteristics of cicadas is their synchronized emergence in large numbers, known as a brood. Cicada broods are classified based on the specific species and geographic region where they emerge. The periodic emergence of cicadas can range from annual occurrences to more prolonged cycles, such as every 13 or 17 years.
Cicadas are divided into two main groups:
- Annual Cicadas: These cicadas emerge every year, typically in smaller numbers compared to periodical cicadas.
- Periodical Cicadas: These species have longer life cycles, emerging in massive numbers after 13 or 17 years underground.
Life Cycle of Cicadas
Understanding the life cycle of cicadas is crucial for effective pest control strategies. Cicadas have a unique life cycle that consists of three main stages:
- Egg Stage: Female cicadas lay eggs in tree branches, where they hatch into small nymphs that fall to the ground.
- Nymph Stage: Nymphs burrow underground and feed on tree roots for several years, depending on the species.
- Adult Stage: After several years, nymphs emerge from the ground as adults, shedding their exoskeletons and mating to start the cycle anew.
Signs of Cicada Infestation
Before implementing control measures, it’s essential to identify the signs of a cicada infestation in your area. Here are some common indicators of a cicada presence:
- Loud Buzzing Noise: The distinctive buzzing sound produced by male cicadas to attract mates is the most recognizable sign of an infestation.
- Visible Adult Cicadas: Spotting adult cicadas on trees, branches, or walls is a clear sign of their presence in the area.
- Damage to Trees: Nymphs feeding on tree roots can cause wilting, yellowing leaves, or dieback in affected trees.
- Holes in the Ground: Exit holes in the soil left by emerging cicadas can indicate an infestation in the vicinity.
If you notice any of these signs in your area, it’s time to take action and implement control measures to manage the cicada population effectively.
Control Measures for Managing Cicada Infestations
Managing cicada infestations requires a combination of strategies to reduce their numbers and minimize their impact on trees and plants. By implementing the following control measures, you can effectively control cicada populations and protect your outdoor space from their damaging effects.
Natural Predators of Cicadas
One of the most effective ways to control cicada populations is by promoting the presence of their natural predators. Birds, such as robins, grackles, and blue jays, feed on adult cicadas, helping to reduce their numbers naturally. Additionally, predatory insects like assassin bugs, mantises, and spiders can prey on cicada nymphs, keeping their populations in check.
Use Physical Barriers
To protect valuable trees and plants from cicada damage, you can use physical barriers to prevent adult females from laying eggs. Netting, cheesecloth, or fine mesh covers can be placed over trees and shrubs to block access to egg-laying sites. Make sure to secure the barriers tightly to prevent cicadas from reaching the vegetation.
Pruning and Tree Maintenance
Regular pruning and tree maintenance can help reduce the impact of cicadas on trees and shrubs. Remove dead or damaged branches, as they can attract egg-laying females and weaken the overall health of the plant. Trimming back vegetation can also deter cicadas from laying eggs and reduce their numbers in the area.
Chemical Control
In severe infestations, chemical control methods can be used to reduce cicada populations effectively. Insecticides containing carbaryl or pyrethroids can be applied to trees and shrubs to kill cicadas on contact. Follow the instructions on the product label and apply the insecticide during the early morning or late evening when cicadas are most active.
Biological Control
Biological control methods involve using natural enemies of cicadas to manage their populations. Entomopathogenic fungi, such as Beauveria bassiana, can infect and kill adult cicadas without harming beneficial insects or wildlife. Release these beneficial fungi in the vicinity of cicada-infested trees to help control their numbers organically.
Trap and Remove Adult Cicadas
Setting up traps to capture adult cicadas can be an effective way to reduce their numbers in a targeted area. Place sticky traps or netting around trees and shrubs to catch adult cicadas as they emerge from the ground. Regularly empty and dispose of trapped cicadas to prevent further infestation and reduce their impact on nearby plants.
Avoid Planting Host Trees
To prevent future cicada infestations, avoid planting trees and shrubs that are preferred hosts for egg-laying females. Certain tree species, such as oak, maple, and fruit trees, are more attractive to cicadas and are more likely to suffer damage during an infestation. Choose resistant tree varieties that are less susceptible to cicada feeding and egg-laying to minimize their impact on your landscape.
Conclusion
By taking proactive steps to manage cicada infestations, you can protect your outdoor space from the damaging effects of these noisy insects. Whether through promoting natural predators, using physical barriers, or implementing chemical control methods, there are various strategies available to effectively control cicada populations and minimize their impact on trees and plants. By following the tips provided in this article, you can enjoy a quieter, more peaceful summer season free from the buzzing of cicadas. Remember, with the right approach and consistent effort, you can successfully manage cicada infestations and protect your environment for years to come.
