Every year it goes the same way on the islands: the first warm evening in March, somebody opens the porch door, and within five minutes the ankles are under attack. The homeowners who enjoy their patios all summer are the ones whose program started before that evening — not after it.
Why timing is the whole game
A mosquito program is population suppression, not extermination. Each monthly barrier treatment knocks down the adults resting in your foliage and interrupts the breeding cycle in your yard. Start in March and you’re suppressing a small, early-season population — every visit builds on a low baseline. Start in July and you’re fighting a population that’s had four months and a dozen tidal cycles to compound. Same product, same yard, completely different results.
The Coastal Empire calendar
March: first barrier treatment, plus the spring walk — every pot, tarp, gutter, and low spot that holds water gets dumped, drained, or treated. April through October: monthly barrier visits. Coastal rain is why the cadence is monthly — product binds to foliage fast, but a Savannah thunderstorm season is relentless. November: last visit as nights cool. That’s a nine-month season, and it’s the honest length of mosquito pressure on the marsh side.
What a visit actually does
Two things. The barrier mist treats the underside of foliage, fence lines, under-deck shade, and the shrub layer — the places adult mosquitoes rest during the heat of the day. Then the breeding-source walk: larvicide goes into standing water that can’t be drained (ornamental ponds, drainage swales, the bromeliad cups), and anything that can be dumped gets flagged for you. The visit takes 20–30 minutes, and you can be back outside shortly after it dries.
The marsh reality, honestly
If your property backs up to the marsh, no program on earth delivers zero mosquitoes — the marsh breeds them on every tide, and some will always fly in. What a good program delivers is a yard you actually use: an 80–90% reduction at the patio where you sit, instead of a yard you surrender from May to October. We’d rather tell you that on the phone than have you find it out in August.
Your half of the job
Once a week, walk the yard with one rule: if it holds water for five days, it breeds mosquitoes. Gutters that drip, the tarp over the grill, the tray under the planter, the kiddie pool, the boat plug. Five minutes, once a week, doubles what we can do from the truck. And for the big events — the graduation party, the Fourth — ask about a one-time event spray timed 48–72 hours out.
The porch season is nine months long here. It starts when you start — and March beats July every single time.
