- Eastern Indiana: Delaware and Madison counties.
Low-Activity Zones:
- Southern Indiana: Minimal emergence expected in counties like Vanderburgh and Warrick.
What to Expect During the Emergence
Impact on Indiana Residents
Environmental Benefits:
- Soil Aeration: Cicada nymphs improve soil structure during their underground phase.
- Nutrient Cycling: Dead cicadas provide a nutrient boost for local ecosystems.
- Food Source: Cicadas are a protein-rich meal for birds, mammals, and reptiles.
Potential Concerns:
- Noise Pollution: The loud mating calls can be disruptive, especially in urban areas.
- Tree Damage: Egg-laying can cause flagging (death of small branches) in young or stressed trees.
- Nuisance Factor: Large numbers of cicadas can be overwhelming for some residents.
Tips for Indiana Residents
- Protect Young Trees: Cover trees with mesh netting (1/4 inch or smaller) to prevent egg-laying damage.
- Delay Planting: Avoid planting new trees or shrubs until after the emergence.
- Embrace the Experience: Encourage children and community members to learn about this rare event.
- Limit Outdoor Lighting: Bright lights can attract cicadas, increasing nuisance in residential areas.
- Avoid Pesticides: Cicadas are harmless and do not bite or sting; pesticides are unnecessary and harmful to the environment.
