What this means for Boca Raton residents
For Boca Raton, the notice is a reminder that mosquito season is still active into the fall, and that the county is treating populated areas to keep both mosquito levels and the risk of vector-borne disease in check. The spraying happens after dark, when mosquitoes are most active, so the practical guidance is straightforward for anyone spending evenings outdoors.
Practical tips for evenings outdoors
- Use an EPA-registered insect repellent and wear long sleeves if you are outdoors after dark, when mosquitoes are most active.
- Drain standing water around your home, including flower pots, buckets, gutters, and anything that collects rain, because mosquitoes breed in standing water.
- Call the aerial spray hotline at 561-642-8775 for the latest status of the operation.
