Discovering cicadas in your chimney can be an unexpected and unsettling experience. These insects, known for their loud mating calls and large emergences every few years, can find their way into homes, seeking shelter or a place to nest. Having cicadas in chimney structures not only disrupts the tranquility of a home but also raises concerns about maintaining a clean and bug-free living environment. Properly addressing this issue is crucial for homeowners who wish to protect their houses from unwanted guests and preserve the integrity of their chimneys.

Why Cicadas Might Be in Your Chimney

Understanding Cicada Behavior

Cicadas are large, winged insects that emerge from the ground every 13 or 17 years, depending on the species. These insects are attracted to dark, sheltered spaces like chimneys, which provide a suitable environment for the nymphs to emerge and shed their exoskeletons. Cicadas typically emerge in the spring or early summer when soil temperatures reach a certain threshold. They then climb up trees, shrubs, or other structures to shed their exoskeletons and emerge as adults.

Identifying Cicada Sounds

The loud, buzzing mating calls of cicadas can be quite disruptive, especially if they are coming from inside a chimney. These sounds, which can reach deafening levels, are produced by males to attract females for mating. The noise can be heard throughout the neighborhood and can be particularly annoying at night when people are trying to sleep.

Preventing Cicadas from Entering Your Chimney

Importance of Chimney Caps and Dampers

Installing a termination damper can potentially block cicadas and other elements from entering your chimney. These dampers are designed with professional-grade materials that can prevent insect intrusion but also block high winds and weather elements, ensuring the chimney's integrity. Additionally, a proper chimney cap is crucial as it serves to keep out debris, critters, and specifically cicadas, maintaining the cleanliness and functionality of your chimney system. Regular checks for the integrity and security of the chimney cap are recommended to ensure it is not rusted or missing.

Sealing Gaps and Tuckpointing

To further limit cicadas from entering your chimney, it is essential to address any gaps in the mortar. These gaps can appear inviting to cicadas looking for a nesting place. Tuckpointing, the process of repairing mortar joints in brickwork, is critical during periods when cicadas are active.

What to Do If Cicadas Are Already in Your Chimney

Non-Harmful Methods to Remove Cicadas

If cicadas have already entered the chimney, homeowners can use non-harmful methods to encourage them to leave. Ensuring the flue is closed can prevent these insects from moving further into the home. Additionally, while cicadas are part of the ecosystem and their removal should be handled with care, homeowners can contact professional services that specialize in eco-friendly removal methods to ensure that the insects are not harmed while being removed from the chimney.

Homeowners should consider contacting a chimney professional if the presence of cicadas in the chimney persists. Certified chimney technicians can inspect the chimney cap, crown, and mortar for any damages or gaps that might be allowing cicadas to enter. They can repair these issues to help prevent future infestations. Moreover, if the chimney cap is missing or damaged, it is crucial to have it replaced or repaired, as it serves as a critical barrier against cicadas and other critters.
