Cicadas are an interesting phenomenon in Colorado, known for their loud buzzing sounds that fill the summer air. While these insects are generally harmless to humans and pets, their presence can be overwhelming due to their sheer numbers. Understanding their lifecycle and behavior is crucial for managing their impact on your property.
Cicadas have a unique lifecycle, with some species emerging every 13 or 17 years, while others appear annually. In Colorado, cicadas usually emerge during the late summer months. They spend most of their lives underground as nymphs, feeding on tree roots, before emerging to mate and lay eggs. Their brief above-ground life is characterized by loud, continuous buzzing, which is the mating call of the male cicada.
Although cicadas do not bite or sting, they can cause damage to young trees and shrubs when they lay their eggs. The females use their ovipositors to cut into small branches, where they deposit their eggs. This can lead to a condition known as “flagging,” where branches die back, creating a brown, wilted appearance. While established trees usually recover, young plants may suffer more significant damage.
For homeowners concerned about the impact of cicadas, there are several steps you can take:
Despite their noisy and sometimes destructive nature, cicadas play an important role in the ecosystem. They aerate the soil through their tunneling activities as nymphs, and after they die, their bodies provide a rich source of nutrients for the soil. Additionally, they serve as a food source for various predators, including birds and small mammals.

Ronnie came out and completed an inspection in our home. He gave us good news that we did not have an insect problem. He was very knowledgeable, courteous and professional. Although they typically do not deal with our particular problem, they were willing to do an inspection and point us in the right direction. The gal in the office went above and beyond to make sure we were taken care of. Thank you!
