If you live anywhere from Sebastian to Vero Beach to Melbourne, you already know: mosquito season on the Treasure Coast is no joke. With the Indian River Lagoon, summer rains, and year-round warmth, our corner of Florida is one of the most mosquito-friendly places in the country. Knowing when the season peaks — and how to prepare — means you actually get to enjoy your yard.
When does mosquito season start in Florida?
On the Treasure and Space Coast, mosquitoes are active nearly year-round, but the season ramps up hard with the warm, wet months. Expect activity to climb from spring and peak through the summer rainy season (roughly June through September), when afternoon storms leave standing water everywhere. The best time to start a control program is before that peak — getting ahead of breeding is far easier than chasing a swarm.

- The Indian River Lagoon and its salt marshes are massive natural breeding grounds.
- Daily summer rain refills every container, bromeliad and low spot with fresh standing water.
- Warm temperatures speed up the mosquito life cycle — eggs to adults in about a week.
- Screened lanais and dense landscaping give adult mosquitoes shady places to rest.
How to reduce mosquitoes around your home
Mosquitoes need standing water to breed, so the single most effective thing you can do is eliminate it:
- Dump and scrub anything that holds water weekly — plant saucers, buckets, tarps, toys, gutters.
- Flush out bromeliads and check the lanai for trapped water.
- Keep gutters clear and grade low spots that puddle after rain.
- Change birdbath and pet-bowl water every few days.
- Trim dense shrubs where adults rest during the day.
You can control your own yard, but mosquitoes fly in from the lagoon, retention ponds and neighbors' properties. A professional mosquito program treats the resting areas where adults hide and the spots where they breed — knocking down the population, not just one bite at a time.
The University of Florida has detailed profiles of our local mosquito species. When you want your yard back, our mosquito control targets both the adults and the breeding sites — and pairs perfectly with a year-round plan so you're protected before the summer peak.
