Camping season is here, and while you may be dreaming of nights under the stars and s’mores by the fire, one tiny creature could ruin your outdoor fun. You know them, and you probably hate them: mosquitoes.
A new ranking of U.S. states reveals where these buzzing pests are most active in summer 2025, and Florida claims the not-so-coveted top spot. If your vacation plans involve tents, trails, or lakesides, it’s worth knowing where mosquitoes are biting hardest, so you can plan, pack, and protect accordingly.
Florida: Sunshine and Swarms
Florida leads the nation with the highest concentration of mosquito species, 80 to be exact. Combine that with an average summer temperature of 81°F and over 7 inches of rainfall, and you’ve got a mosquito haven. While West Nile virus rates remain low in the state, Floridians are clearly concerned.
Online searches for mosquito prevention top 1,450 per 100,000 people, suggesting that both residents and visitors are on high alert. If you’re camping near Florida’s wetlands or waterways this summer, prepare to swat.
The South Still Reigns as Mosquito Country
Louisiana, South Carolina, Mississippi, and Georgia round out the top five mosquito-heavy states, thanks to their hot, humid climates and consistent rainfall. Louisiana may not have quite as many mosquito species as Florida, but it does report higher rates of West Nile virus. South Carolina stands out not just for its coastal camping options, but also for leading the nation in mosquito prevention searches.
Mississippi’s mosquito count is lower, but the state sees more virus-related cases, putting campers on guard. Georgia offers a similar story: a moderate mosquito presence but high online activity from people looking to stay bite-free.
Surprises and Search Spikes
While the South dominates the list, Nebraska might be the most surprising inclusion. It ranks sixth overall for mosquito activity but holds the highest rate of West Nile virus cases in the country, more than double the next state. That’s a critical reminder that it’s not just the volume of mosquitoes that matters, but also the potential health risk.
Delaware, by contrast, doesn’t experience high virus rates or huge mosquito populations, yet residents have flocked to Google to search for prevention tips. It shows that awareness (and concern) can be just as telling as climate.
The rankings are based on five equally weighted factors: average summer rainfall, average summer temperatures, the number of mosquito species, the number of reported West Nile cases in 2024, and Google search interest in mosquito prevention. Put all of that together, and the resulting list highlights the regions where mosquitoes are not only present but being taken seriously by the public.
While there’s no escaping mosquitoes entirely in summer, knowing where they’re most active can help you better prepare. For those planning a camping trip to popular destinations in the South or Midwest, it’s worth investing in quality repellent and protective gear, choosing campsites away from stagnant water, and planning your outdoor time around peak mosquito hours.
Campers headed to states like Vermont or New Hampshire may get a bit of a break, though even these areas report rising search interest in mosquito prevention, proof that no campsite is entirely immune.
Don’t Let the Buzz Kill Your Vibe
Whether you’re heading to Florida’s Everglades, the woods of Mississippi, or the plains of Nebraska, mosquitoes are just another part of the summer equation. But with a little planning and awareness, they don’t have to ruin your next great outdoor escape.
Stay smart, stay protected, and enjoy every bite-free moment of your adventure.
