Mosquito Control in Horry County
March through November on the coast. Longer if you're near the marsh.
Or book a free pest evaluation and we'll find your breeding sources.
You can't spray your way out of a mosquito problem if the property is still producing them.
This is the part most companies skip. Treating foliage kills the adults resting there today. But if there's water sitting somewhere on your lot, new adults are emerging continuously and you're back to square one in days. Real control is habitat first, treatment second.
Mosquito Season on the Coast
- March–May — activity begins as temperatures climb; spring rain fills breeding sites.
- June–September — peak. Heat plus afternoon thunderstorms create ideal conditions.
- October–November — pressure tapers but doesn't stop, especially near marsh.
- Winter — mostly quiet, though warm spells can bring short resurgences.
Saltmarsh mosquitoes are a different problem
If you're in Murrells Inlet, Little River, or anywhere backing to marsh, you're dealing with saltmarsh species that breed in tidal pools. Those pools refill with every tide, so the breeding habitat is effectively infinite and it isn't on your property. Treatment focuses on making your yard inhospitable to them, since you can't eliminate the source.
Where They're Breeding on Your Property
Most container-breeding mosquitoes need only a small amount of standing water for about a week. Common sources people miss:
- Clogged gutters — the single most overlooked source
- Plant saucers and potted plant trays
- Tarps, boat covers, and grill covers holding pockets of water
- Irrigation valve boxes
- Corrugated downspout extensions
- Low spots that stay wet for days after rain
- Bird baths and pet bowls that aren't changed weekly
- Old tires, buckets, wheelbarrows, toys
Your technician will walk the property and point these out. Fixing them is usually free and does more than any treatment.
Where They Rest
Adult mosquitoes don't spend the day in open sun. They rest in cool, shaded, humid spots, which is exactly where treatment goes:
- Dense shrubs and hedge interiors
- Under decks and porches
- Thick ground cover and ivy
- Shaded fence lines and tree lines
- Behind and under stored items
The Season, in Real Terms
Our mosquito program runs 7 monthly treatments, starting in April or early May and continuing through October or early November — the stretch when mosquitoes are actually active on this coast. Every visit is the same two-step process.
How We Actually Treat It — A Two-Step Process
Most companies spray and leave. We treat both ends of the mosquito's life cycle, because killing today's adults does nothing about tomorrow's.
1. Fogging — the adults
Using a backpack mister, your technician fogs around the property, treating the trees and bushes where mosquitoes rest during the day with OneGuard. This knocks down the adult population on your property and leaves residual on the foliage where they land. It's what buys you your evenings back this week.
Heavy rain shortens it. That's not a failure of the product — it's why treatment is recurring through the season rather than one-and-done.
2. Altosid granules — the larvae
Applied to standing water sources you can't eliminate — bird baths, downspouts, old tires — to prevent breeding before it starts. The active ingredient is (S)-methoprene, an insect growth regulator.
Here's what it does, and it's clever: it doesn't kill larvae. Larvae exposed to methoprene develop normally right up to the pupal stage — and then die before emerging as biting adults. The mosquito never completes its life cycle.
- Provides up to about 30 days of control in standing water
- Target-specific — does not affect fish, waterfowl, mammals, or beneficial predatory insects
- Used in the places you can't drain: bird baths, downspouts, old tires, drainage areas, low spots, catch basins, ornamental water
This is the part that compounds
Fogging alone means you're killing adults that keep getting replaced. Granules mean fewer adults get produced in the first place. Run both through 7 monthly visits and the population you're fighting in August is smaller than it would have been — which is why a program beats a one-time service by more than the visit count suggests.
Common Questions
Do mosquito treatments hurt pollinators?
Application matters. Treatments are directed at resting areas rather than blooming plants, and timing avoids peak pollinator activity where possible. Your technician applies according to the product label, which includes pollinator protection requirements.
Will one treatment fix it?
No, and anyone promising that isn't being straight with you. Adults are continually emerging and moving in from surrounding property. Control means recurring treatment through the active season, paired with removing what you can on your own lot.
Why am I getting bitten at dusk specifically?
Many species are crepuscular — most active at dawn and dusk when humidity rises and wind drops. No-see-ums follow a similar pattern and are common near water here.
Do you use mosquito traps?
No. We don't install traps — they catch a small fraction of the population and do nothing about breeding habitat on the rest of your property. Our two-step program of fogging and larvicide treats the adults you have now and prevents the next generation from emerging, which does more than any trap or backyard gadget.
Mosquito control by town
Near the marsh, pressure is heavier and the honest plan is to make your yard usable, not the area mosquito-free:
Mosquito Control in Little River — tidal marsh & Intracoastal waterway saltmarsh pressure.
Mosquito Control in North Myrtle Beach — the Cherry Grove marsh hotspot.
Mosquito Control in Murrells Inlet — the saltmarsh, refreshed by every tide near the MarshWalk and Prince Creek.
Mosquito Control in Garden City Beach — a narrow ocean-and-marsh strip with tidal pressure right behind the homes.
Mosquito Control in Surfside Beach — family cottages and rentals with container breeders plus marsh-edge pressure.
Mosquito Control in Myrtle Beach — dense neighborhoods and daytime-biting Asian tiger mosquitoes breeding in gutters and drains.
Mosquito Control in Carolina Forest — master-planned communities laced with retention ponds and preserved wetlands.
Mosquito Control in Conway — Waccamaw River bottomland and floodwater mosquitoes after the river rises.
Mosquito Control in Longs — big wooded and new-construction lots with ditches, ponds and treelines.
