From being one of the top golf destinations in the country to being home to stunning spots like Driessen Beach Park and Coligny Beach Park, Hilton Head has plenty of reasons for residents and visitors to spend time outside. But with around 215 sunny days a year, this island also boasts lagoons, creeks and sea marshes, which is great for wildlife, but also great if you are a mosquito. Without worrying about itchy bites being your trophy for your outside time, let the experienced team at MosquitoNix explain when peak mosquito season in Hilton Head is and how to stay safe.

Peak Mosquito Season

The regular mosquito season in Hilton Head starts around mid-March when the temperatures get warm enough for the mosquitoes and other bugs to wake up. While insects can become active when it hits around 40 degrees Fahrenheit, they thrive when temps hit around 50 degrees. Since Hilton Head stays so nice for so long, mosquito season can go all the way into October. The peak mosquito season in Hilton Head is from June to September.

What Makes a Peak Mosquito Season

Why is it called peak mosquito season? This is when all of the conditions mosquitoes and other bugs love are met. It's when the humid climate, plenty of wet weather and higher temperatures create a variety and multitude of breeding grounds for bugs to mate and lay their eggs. Mosquitoes and other insects live for humidity and temperatures over 50 degrees Fahrenheit. They also need wet weather, as standing water is where they breed and lay eggs, and Hilton Head delivers those conditions.

How to Protect Yourself From Mosquitoes

When you leave to walk the miles of bike paths in the Hilton Head area, you can take precautions for yourself and your pets. Do these tips during peak season, but don't forget these on any warm day when mosquitoes could be active.

  • Wear bug spray with DEET
  • Wear long-sleeved clothing, including a hat
  • Avoid the outdoors at dusk and dawn, when bugs are the most active
