This year marks the first time in 221 years that two periodical cicada broods will emerge at the same time. The first emergence is expected sometime between late April and early June as the ground begins to warm. While the two broods occupy different geographical areas, significant parts of Illinois, including Kenilworth, can expect to see large quantities of cicadas over the coming months.
Cicadas are harmless to humans and pets, but newly planted trees and shrubs may be at risk of sustaining long-term damage due to the temporary changes that will take place in the ecosystem and food chain. The Village's arborist consultant has provided the professional opinion that the parkway trees planted this past fall are not likely to be at risk for damage and do not require protective netting or other means of cicada mitigation. However, residents are welcome to protect the trees and landscaping on their property as they see fit.
