What this tracker can and cannot tell you
The useful question for Key Biscayne is not just "are there mosquitoes in Miami-Dade?" There are always mosquitoes in South Florida. The better question is whether the island is likely to feel bad today: after rain, with humid still air, around shaded yards, canals, the Village Green, mangroves, and park edges. That is what the pressure score tries to answer.
The score is a local nuisance signal, not a public-health warning. It uses recent and forecast rain from Open-Meteo, plus current humidity and wind. Rain matters because standing water creates breeding sites; humidity and light wind make bites more noticeable outside. For community signal, we read public VKB 311 reports and point residents to official channels instead of collecting reports ourselves.
Why rainy season gets rough here
Key Biscayne is small, low, planted, and surrounded by water. A heavy afternoon storm can leave water in yard drains, bromeliads, planters, toys, buckets, construction materials, boat covers, and low pockets near the street. Canal homes and lush shaded lots can feel different from an open, breezy beachfront even on the same evening.
The CDC's mosquito-prevention guidance is blunt because it works: empty, scrub, turn over, cover, or throw out items that hold water. For KB, the practical version is a five-minute yard walk after storms. Check plant saucers, bromeliads, drains, pool toys, tarps, kayak covers, outdoor storage bins, and anything under dense landscaping.
What official data exists
The Village says VKB 311 uses SeeClickFix for location-based community issue reporting and service-request tracking. SeeClickFix exposes a public Key Biscayne issue feed, including a Mosquito Inspection or Control request type. We check that public feed twice daily and also look for mosquito/spray keyword matches, because older items may have been filed under a broader category.
Mosquito control itself is still a Miami-Dade County function. The county's Mosquito Control program is the official source for mosquito inspection, surveillance, and control information, and residents can file a county mosquito inspection request through Miami-Dade 311. The Village also points residents to Village Connect and VINS for official emails, public-health warnings, public works notices, emergency alerts, and community updates.
Florida DOH publishes weekly arbovirus surveillance reports. Those reports are countywide public-health context for mosquito-borne illnesses such as dengue, West Nile virus, chikungunya, Zika, and related surveillance categories. They are important, but they are not the same thing as whether your patio is unbearable after sunset.
When to file an official inspection request
Use VKB 311 when you want a Village-facing record of a neighborhood concern. Use county channels when you need county action: standing water that is not on your property, a vacant lot, a drainage problem, a recurring swarm, or a suspected breeding site that needs inspection. Key Biscayne Guide reads public signals, but it should not become a parallel complaint inbox unless we have a real operations workflow behind it.
If you are reporting to the county, be specific about the location and the standing-water source. "Bad mosquitoes near the Village Green after rain" is less actionable than "standing water in a blocked drain at the northeast corner after storms." For private homes, start with source reduction before expecting spray to solve it. Adulticide spraying can knock down adults for a short window, but larvae keep coming if water remains.
Best KB habits after a storm
- Walk the yard the morning after heavy rain and dump anything holding water.
- Check plant saucers, bromeliads, boat covers, toys, buckets, bins, and clogged gutters.
- Use EPA-registered repellent for dusk walks, outdoor dinners, and kids' sports after wet weeks.
- Run fans on patios; light wind helps because mosquitoes are weak fliers.
- Watch Village Connect and the VKB 311 public feed when residents start flagging the same problem area after storms.
