When Is Tick and Mosquito Season in South Carolina? (Hint: Almost Year-Round)

In much of the country, mosquito and tick season is a tidy few months in summer. On the South Carolina coast, it's a lot longer and blurrier than that. If you've wondered when you can finally stop worrying about bites in Conway, the honest answer is: not for much of the year. Here's the real seasonal picture.

Mosquitoes: spring through late fall, and beyond

Mosquito activity typically ramps up in early spring as temperatures climb and rain pools, peaks through the hot, wet summer, and continues well into fall. In mild years, activity can linger nearly year-round on the coast, since we rarely get the sustained freezes that shut mosquitoes down elsewhere.

No-see-ums: worst in the warm, damp months

Coastal no-see-ums follow a similar arc, thriving in the warm, humid stretch and hammering marsh-side properties from spring through fall. Damp conditions after rain can trigger flare-ups anytime in that window.

Ticks: active even in winter here

Ticks may be the biggest surprise. While activity peaks in the warmer months, our mild winters mean ticks can stay active on warm days year-round, and some species are actually more active in cooler weather. There's really no season in the Lowcountry when tick checks stop mattering.

Why the long season matters

A biting season this extended changes how you protect your home. A single spring treatment won't carry a coastal yard through to fall, and letting your guard down in the 'off-season' can still leave you exposed to ticks. Consistent, season-long protection is what actually keeps the pressure low.

Planning your protection

The practical approach is recurring treatment through the long warm season, ideally started before the spring ramp-up, plus year-round awareness for ticks. Reducing standing water and keeping the yard trimmed helps continuously. Conway SC Pest Control times mosquito, no-see-um, and tick programs to the actual local season rather than a national calendar.
