In May 2026, Seminole County reminded residents that warmer nights and the summer rainy season raise mosquito activity across the county. That timing matches what many Winter Springs and Casselberry neighborhoods already feel after afternoon storms: more bites near shaded yards, screened porches, and HOA retention ponds.
County mosquito programs treat public breeding sites when they can. The water that sits in your own yard still belongs to you. A well-kept pond with fish and open edges usually supports fewer mosquitoes than a clogged gutter or a toy left upright after rain.
Why pond communities still see pressure
Permanent ponds and lakes often hold predators that eat larvae. Temporary water is the bigger local problem. After a heavy rain, look for:
- Plant saucers, buckets, and recycling bins that hold water for more than a few days
- Clogged roof gutters and downspout splash blocks
- Tarps, boat covers, and wheelbarrows that cup rainwater
- Low spots in the lawn that stay wet between storms
- Birdbaths and pet bowls that go days without a refresh
HOA ponds can still contribute when shoreline weeds get thick or when storm drains dump debris into shallow edges. If your lot backs a pond, keep your side of the fence clear of stacked pots and unused planters. Report overgrown common areas to the association so the county or pond contractor can inspect them.
A simple weekly walk
Pick one day after the weekend storms and walk the property for ten minutes.
- Tip or empty anything that holds water.
- Flush birdbaths and refresh pet water.
- Check gutters from the ground for overflow stains.
- Note soggy low spots and fill or regrade them when you can.
- Keep grass trimmed so adults have fewer resting spots near the house.
Repellent helps when you are outdoors at dusk. Source reduction cuts the next hatch before it starts.
When bites stay heavy after cleanup
If bites stay heavy after you clear standing water, the breeding site may sit off your lot - a neighbor's tarp, a blocked swale, or a weedy pond edge.
