Boasting over 22 miles of stunning beaches down the gorgeous Atlantic Coast, Jacksonville is well known for its family-friendly activities and plenty of places to catch the sunshine outside. But when you live in a warm, humid climate with plenty of wet weather conditions, mosquito season is like nothing you've experienced before. Your caring and experienced neighbors at MosquitoNix want you to know about Jacksonville's peak mosquito season so you can stay bite-free.

When Peak Mosquito Season is in Jacksonville

Mosquito season in Jacksonville is almost the entire year. It starts in March when the temperature gets up to 50 degrees Fahrenheit, which is when bugs and insects wake up from their hibernation. Since the weather in Jacksonville stays warm for so long, mosquito season can go through November until it gets cold enough for their activity to slow down and send them back to hibernation.

Peak season is when mosquito activity is the highest. The most humid months, where the temps stay 70 degrees or higher, and the rainy and wet weather is more consistent, are May through October. Since mosquitoes thrive in warm, humid weather and need standing water to breed and lay their eggs, the mild winters don't give residents a long cooling-off period.

How to Protect Yourself

  • Wear long-sleeved, loose-fitting clothing, as light in color as possible
  • Wear bug spray with DEET in it and reapply as directed
  • Stay inside during dusk and dawn

If you do venture out to soak up all Jacksonville has to offer, do a few basic things to protect yourself and your family from bug bites. Before you leave, check your clothing. Mosquitoes and other bugs like dark colors, so wear lighter tones. Opting for long-sleeved clothes is not only better to protect your skin from the sun, but from mosquitoes.

Bugs are most active at dusk and dawn when the sun is weakest, so try to avoid being outside during those times. But when you do go out, don't forget the bug spray.

How to Keep Your Yard Mosquito-Free

  • Dump standing water
  • Clean bird baths and bring in pet bowls
  • Keep the lawn mowed short
  • Trim trees and other greenery away from the house

A few minutes a day checking for standing water and picking up debris will go a long way to keep the mosquitoes from taking up residence in your yard. Mow your lawn as short as you can, and don't forget about keeping other greenery on your property trimmed.
