As pool season comes into view, another phenomenon begins to stir beneath the surface—cicadas. These buzzing insects, known for both their annual and periodic appearances, not only herald the arrival of summer but also pose unique challenges for swimming pool owners. Their presence can be detrimental to your pool’s health, from clogged filters to an increased need for chlorine. In this blog, we'll go over how to take care of your pool during cicada season. From understanding their life cycle to implementing proactive measures, join us as we dive into the world of cicadas and pool care.


Understanding Cicadas and Their Behavior

Cicadas undergo three stages in their life cycle: eggs, nymphs, and adults. Female cicadas lay eggs in tree branches, which eventually hatch into nymphs. These nymphs burrow into the ground and nourish themselves on tree roots for several years. Once they mature, they surface from the ground as adults, shed their skins, and begin the familiar buzzing noise that signals their arrival.

In the US, two primary types of cicadas are found: annual cicadas and periodical cicadas. Annual cicadas are the larger of the two and have colorations ranging from green to brown. They have a two to five year life cycle, with many of the broods’ cycles overlapping, causing these cicadas to emerge every year all over the country. 

Periodical cicadas are smaller and have a darker body, accessorized with their vibrant orange eyes and wings. These cicadas have life cycles of either 13 or 17 years, meaning we see them less often than the annual cicadas. There is occasional overlap between the broods’ cycles. Typically, a 13-year and 17-year brood will emerge at the same time every 5-6 years, though will be in their own separate spaces and won’t physically overlap. However, these broods emerge en masse, meaning you’ll see a large uptick in cicadas in their specific locations.

But why are cicadas attracted to swimming pools? Cicadas, especially females looking for an egg-laying spot, are drawn to water sources for hydration. They may mistake the reflective surface of a swimming pool as a natural water source, such as a lake or a pond. If your swimming pool is located near trees, which are common egg-laying sites for cicadas, there is an increased likelihood of cicadas being in the vicinity and possibly landing in the pool.

If cicadas are plaguing your swimming pool, it's important to take appropriate measures to reduce their presence and keep your water chemistry balanced.


How Cicadas Impact Your Pool's Water Chemistry

Cicada season can significantly affect the chemistry of your swimming pool water. These buzzing insects not only introduce inorganic matter into your pool, but also emit nitrogen, which can disrupt the water balance and reduce chlorine effectiveness. It's crucial to understand how cicadas affect your pool's water chemistry to keep your pool clean and healthy.

Decomposing cicadas release nitrogen into the pool water. Increased nitrogen levels can decrease the effectiveness of chlorine, leading to potential issues with water clarity and sanitization. To maintain a proper water balance during cicada season, it's essential to regularly test your pool water and adjust chemical levels accordingly. If nitrogen levels are high, adding chlorine can restore balance. Doheny’s 3” Chlorine Tablets effectively combat the impact of excess nitrogen, helping to keep your pool water swim-ready.

Cicadas also impact your pool by bringing in inorganic matter. As they flutter around and land in your pool, they can carry dirt, leaves, and other debris with them. This organic matter can clog filters and contribute to algae and bacteria growth. 


Keeping Your Swimming Pool Clean During Cicada Season

Here are some key tips to help you maintain your pool when cicadas are in the vicinity:

  • Regular cleaning and skimming to remove cicadas: Since cicadas are attracted to water sources, your swimming pool may become their preferred spot. To minimize their presence, ensure that you clean and skim your pool regularly to remove any cicadas and debris that have fallen in. Use a pool skimmer or net to remove them, focusing on the water surface and the pool walls.
  • Adjusting pool chemicals to minimize cicada presence: Cicadas can leave behind waste and debris that can affect your pool's water chemistry. It's crucial to maintain the appropriate chemical levels to prevent any issues. Regularly test your pool water and adjust the chemicals as needed. Chlorine will be your best friend during cicada season! Learn more about water testing and chemical balancing on our blog.
  • Protecting pool filters and equipment: Cicadas can clog pool filters and damage equipment if not properly managed. Check your pool's filters more often during cicada season and clean or replace them as required. Consider using a pool cover when the pool is not in use to prevent cicadas from entering and potentially damaging the equipment.

By following these simple steps, you can enjoy a clean and well-maintained pool even during cicada season. Stay consistent with your pool maintenance routine and seek professional help if needed.


Keeping Cicadas Out of Your Swimming Pool

You now know how to handle cicadas in your pool, but how do you prevent them from becoming a problem in the first place?

  • Use a solar cover or leaf net: One of the most effective ways to deter cicadas from entering your pool is by using a pool cover. Solar covers and leaf nets can create a barrier that helps to keep the insects out. Doheny.com offers a range of high-quality pool covers designed to offer maximum protection against unwanted debris and pests, including cicadas.
  • Seal gaps and cracks: Cicadas can infiltrate your pool area through small gaps or cracks in surrounding structures. Inspect your pool area carefully and seal any openings you find. This will not only keep cicadas out but also help maintain the overall cleanliness and safety of your pool.
  • Use repellents or deterrents: Another option to discourage cicadas from approaching your pool is by using repellents or deterrents such as insect repellent sprays and sonic devices.

By implementing these preventive measures, you can enjoy a cicada-free swimming pool throughout the summer season. Visit doheny.com to explore our chlorine tablets, test kits, pool covers, and more, all designed to help you maintain a clean and pest-free pool environment.
