Periodical cicadas (aka Magicicada spp.) are fascinating insects that play a crucial role in ecosystems, but their swarming behavior can present challenges and frustrations for many, especially RV owners. Understanding the science behind cicada swarms is essential for navigating these periods with minimal disruption. In this blog post, we'll delve into the life cycle of cicadas, their swarming behavior, and how RV owners can mitigate the impact of cicada swarms on their travels.

Cicada Life Cycle -

Cicadas have a complex life cycle that spans several years. They begin as eggs laid in tree branches, where they hatch and fall to the ground. Cicada nymphs then burrow underground, where they spend on average 13 to 17 years feeding on tree roots. When conditions are right, usually after a specific number of years and the surrounding soil temperature reaching about 65 degrees Fahrenheit, the wingless nymphs will begin to emerge from the ground shedding their exoskeletons to do what they do best, make noise, reproduce and die. This synchronized emergence results in massive swarms that can last for several weeks.

Cicada Swarming Behavior -

The primary purpose of cicada swarms is reproduction. Male cicadas produce loud buzzing or clicking sounds to attract females for mating. These sounds, which can reach more than 90 decibels (dBA) during swarming periods, serve as a form of communication among cicadas to coordinate their activities. As a point of reference, 90 dBA can be as loud as a lawnmower or motorcycle. Environmental cues such as soil temperature and tree sap flow trigger the emergence of cicadas and their swarming behavior. For the most part, cicadas prefer the country, and that’s where the impact on RV owners come into play. There are some city dwelling nomads, but the larger population of Nomadicus RVicus (aka RV owners) take to the open roads.

Impact on RV Owners -

Cicada swarms can pose several challenges for RV owners. The loud noise generated by swarming cicadas can be disruptive, especially for those camping in affected areas. So unfortunately, this may mean that you guy’s are not alone during that candlelight picnic table dinner. However, more problematic issues arise when cicadas land on RVs, or even worse when you experience a head-on collision. In these instances, you can count on our noisy exoskeleton shedding little friends to leave behind some particularly sticky bits and pieces that can be difficult to clean or remove from tight spaces. In some cases, cicadas can even cause significant damage to your unit, such as clogging vents or damaging exterior surfaces, so it’s important to protect these areas if possible and also ensure that screens are in place. In addition, keeping your doors and windows closed if at possible can also assist.

Mitigating Cicada Impact on RVs -

To minimize the impact of cicada swarms on RVs, there are several strategies that owners can employ. Covering vents and sealing cracks can help prevent cicadas from entering the vehicle. Using natural repellents, such as essential oils or garlic spray, can deter cicadas from landing on RVs. Regular cleaning and maintenance routines are also essential to keeping your rig and/or tow vehicle free of cicadas and their debris. If you weren’t aware, most bugs leave behind an acid residue as they (or what’s left of them) decompose. This combined with that beautiful blazing spring and summer sun is a recipe to make toast of your RVs finish. RV.com has a list of 14 Best RV Bug Remover Products that includes reviews on thin spray on/rinse off, thin spray on/wipe off, and thick spray on/wipe off solutions. There seems to be an endless array of options, just ensure any product you select is safe for your finish and doesn’t remove the wax from your paint. That is unless you want to polish up your “wax-on / wax-off” skills every time. One of the solutions that stood out to me was Wash Wax All and I plan on giving it a try. There’s also a product called Bugs Off Pads, but this option requires water which may not always be available. FYI, these are non-affiliate links and we are not sponsors.

Understanding Cicada Broods and Locations -

Cicadas emerge in different broods across North America, with each brood having its own periodicity. Interactive maps and resources are available for RV owners to track cicada broods and plan their travels accordingly. The University of Connecticut has several informational pages on broods and distributions. In addition, the USDA routinely publishes an Active Periodical Cicada Brood map. While periodical cicadas within the same region might make their appearance in the same year, it’s not guaranteed they’ll all show up to the party at the same time. Regions with intense cicada swarms, such as parts of the Midwest and East Coast, should be approached with caution during swarming periods.

In a shell (or exoskeleton) -

Cicada swarms may sound like the latest horror movie plot for RV owners, but fear not, there are ways to survive the buzzing madness with your sanity intact! From dealing with the cacophony of cicada karaoke to the unexpected guests leaving their tiny "gifts" on your RV, it's all part of the adventure of RVing during cicada season.

Sure, cicadas might think your RV's vents are the latest hotspot for their deep dive excursion, but if precautions are taken, frustrations can be reduced. On the brighter side of things, let's take a moment to appreciate Mother Nature's sense of humor. Cicadas may be loud, messy, and a tad clumsy around RVs, but they're also a reminder of the fascinating cycles of life in our natural world. So, buckle up and remember, it's all part of the journey - noisy bugs, unexpected visitors, and all. Happy trails, everyone, and may your travels be filled with everything but cicadas!
