Miami-Dade County Mosquito Control Division Ready for Peak Mosquito Season

County engaged in year-round trapping, surveillance, and larviciding activities, prepared for most active mosquito months

MIAMI (May 03, 2018)

In South Florida, more rainfall means an uptick in mosquito breeding. May showers notwithstanding, the Miami-Dade County Mosquito Control and Habitat Management Division has been keeping a close eye on mosquito activity, and continues to take the necessary steps to stay on top of the movements of the approximately 48 species of mosquitoes present in the area. Mosquito Control remains vigilant and prepared for the annual increase in mosquito activity.

"Our abatement activities do not cease when the rains subside," says Dr. William Petrie, director of the Miami-Dade County Mosquito Control Division. "Because South Florida’s climate is very mosquito-friendly, the Mosquito Control Division’s duties continue throughout the year." Miami-Dade’s team of mosquito control inspectors continue to respond to service requests placed by residents and business owners, regularly treat storm drains with the organic larvicide Bti to limit breeding in them, and administer adulticide via backpack when mosquitoes are found.

The County closely monitors more than 160 traps strategically placed throughout Miami-Dade, keeping tabs on the numbers of mosquitoes present at any given point, which species are in the area, their gender, and whether they are carrying any communicable diseases. The traps are each individually serviced and checked on a weekly basis by a team of environmental technicians.

Mosquito Control has been proactively treating the Wynwood and Miami Beach areas with Bti by truck regularly since the 2016 response to Zika. The two zones are popular with locals and tourists alike.  Reducing the likelihood of mosquito breeding is a critical step in preventing the transmission of vector-borne illnesses such as dengue, malaria, chikungunya and potentially Yellow Fever, which has recently been reported as a growing outbreak in Brazil.

In January of this year, the County, in partnership with the City of South Miami and Lexington, Kentucky-based contractor MosquitoMate, launched an innovative Wolbachia bacteria mosquito control program. Each week, tens of thousands of non-biting male mosquitoes infected with the bacteria that makes them effectively sterile are released into a treatment area sized approximately one-half square mile. Traps abound in a similarly-sized non-treatment area, and the data is being comparatively analyzed and kept. Early results are promising. Learn more here.

The Mosquito Control’s social media pages on Facebook, Twitter and Instagram (@305Mosquito) continue to frequently offer tips on how to “Fight the Bite”. In addition, County representatives make available to local municipalities, homeowner associations, industry groups, as well as community and civic organizations print and electronic mosquito control “Drain & Cover” informational rack cards, brochures, posters and door hangers designed to educate residents. A multi-media advertising campaign that promotes the “Drain and Cover message” is used year-round and heavily promoted during peak mosquito season, typically May to October.  For more tips on how to limit mosquito bites and breeding, visit our mosquito tips & resources page.
