Mosquitoes do not need a pond, a canal or the lagoon to breed. They need water that sits still for about a week, and for the container-breeding species that bite you on your own patio, a plant saucer is plenty. That is the good news: a large share of the mosquitoes in a Florida yard were born in that yard, in something a person can pick up and pour out. What follows is the walk-around, in the order that finds the most.
Why a week is the number that matters
In our summer heat a mosquito goes from egg to flying adult in roughly a week. That is the whole logic of the schedule: empty every container more often than that and the cycle never completes. Container-breeding species also lay their eggs on the damp wall just above the waterline, and those eggs survive drying out and hatch when the container refills. Which is why the instruction is dump and scrub, not just dump.
The obvious ones

- Plant saucers, especially the ones on the lanai that never see rain but catch every watering.
- Buckets, wheelbarrows, watering cans, toys, coolers, and the recycling bin whose lid went missing.
- Birdbaths and pet water bowls — change the water rather than topping it up.
- Tarps, boat covers, kayak hulls and grill covers, which pool in the sag.
The ones almost everybody misses
- Gutters. A single clogged section holds water while the rest of the run drains perfectly, and nobody looks up.
- Corrugated downspout extensions, which hold a little water in every ridge along their length.
- Irrigation valve boxes and water meter boxes, sitting at ground level and filling with every storm.
- Bromeliads, whose cups hold water by design. Flushing each cup weekly with a hose beats pulling the plants out.
- Any low spot still wet two days after a storm — a settled patch, an old stump hole, or where a downspout discharges.
Emptying a container removes the larvae. Scrubbing the inside wall removes the eggs, which are glued on above the waterline and will wait for the next rain. One weekly pass around the yard is the highest-value thing a Florida homeowner does about mosquitoes.
Do mosquito repellent plants work?
Citronella, lemongrass, marigold and the rest get recommended every spring, and the honest answer is that planting them does not create a repellent zone around a patio. The aromatic compounds sit inside the leaf and are released when it is crushed, not passively into the air. Worth growing for their own sake; not a control method.
What is not yours to fix
Some water around a Florida property will never be drained: the marsh, the ditch line, the retention pond behind the subdivision, the lagoon edge. Mosquitoes bred there simply fly in. That is where a professional programme earns its place — treating the shaded resting sites where adults wait out the day, and the water on your property that genuinely cannot be emptied.
Do the yard walk two days after a storm rather than during one. Anything still holding water by then will finish a full mosquito cycle before it dries — and those are the spots worth fixing permanently rather than emptying forever.
If the biting happens at dusk and you never see what is on you, it may not be mosquitoes at all: biting midges pass straight through standard screen, and our guide to no-see-ums in Florida covers those. Otherwise the mosquito identification page names what is on your ankle, and our mosquito control explains what a treatment reaches — with local detail for Fort Pierce. The inspection is free.
