Why Mosquitoes Don’t Quit in Late Season and How Hunters Can Stay Ready

Most hunters assume mosquito season ends when the temperature drops. But in Louisiana and across the South, the story is very different. Warm afternoons sandwiched between chilly mornings can keep several mosquito species active long into fall and early winter. That means even during duck and deer season, hunters can still get bitten when they least expect it.

Late-season mosquito activity often catches people off guard. Marshes stay wet, swamps hold heat, and the woods create pockets of warm, humid air that mosquitoes love. A quick warm spell can wake them right back up. Many hunters have experienced those surprise bursts of swarming when a cold week suddenly flips to the mid-sixties.

One of the main species that sticks around is the Asian Tiger Mosquito. It bites throughout the day and thrives whenever Louisiana gets a warm stretch. The Southern House Mosquito also remains active later than most and is especially common in marshes and low-lying wetlands. Even species that prefer dusk and dawn activity tend to stay busy on warmer winter days. Any hunter spending time near standing water, flooded fields, or shady bottoms can expect to encounter mosquitoes even in late fall.

Because bugs are less noticeable this time of year, hunters often drop their guard. That’s when late-season bites become a bigger problem. These mosquitoes can be surprisingly aggressive after periods of dormancy. They take advantage of long sits in deer stands and duck blinds, and with hunters focused on the sky or the tree line, they know they have an easy target.

Carrying reliable protection in your pack is still essential, even when temperatures feel cool. A repellent that performs well in unpredictable weather can make the difference between a comfortable hunt and a distracting one. Picaridin-based repellents work especially well during this season because they provide long-lasting coverage without the strong chemical smell that can alert game. HUNT Refined Repellent is a DEET-free, scent-free option that offers 12 to 14 hours of protection from mosquitoes and ticks. It is safe on skin, safe on gear, and won’t damage firearms, which makes it ideal for duck bags and deer packs.

Late-season hunting is one of the best times to be outdoors. The woods are quiet, the marshes are cool, and the action can be unforgettable. With the right protection, you can settle in, stay focused, and enjoy every moment of the season without swatting at bugs.
