As cooler air approaches, continue to protect yourself and your family from mosquitoes

Cooler and drier weather conditions doesn't mean you can let your guard down on potential mosquito breeding

MIAMI (November 07, 2017)

In recent weeks, Miami-Dade has seen its share of cooler temperatures and drier air. However, while the change in temperatures may help reduce mosquito breeding, there are still opportunities for mosquito breeding to occur.

“Mosquito breeding and the infectious diseases that mosquitoes can transmit through their bites such as Zika, Dengue Fever, West Nile Virus, and Chikungunya are important reasons for residents to remain vigilant even as cooler air makes it way to Miami-Dade County,” says Dr. William Petrie, the Miami-Dade County Mosquito Control and Habitat Management Division's new director.

Here’s what residents can do to protect themselves and their families from mosquito bites:

1. Drain all standing water left in the yard to control mosquito breeding. Female egg-bearing mosquitoes, especially the Zika -carrying Aedes aegypti species, love garbage cans and recycle carts, pool and boat covers, coolers, toys, and flower pots. “Certain species of mosquitoes are container breeders, and do not need much water to lay their eggs on or near – as little as a one-ounce bottle cap is enough,” added Dr. Petrie.

2. Cover exposed skin with a good mosquito repellent. Use only Environmental Protection Agency-approved repellents containing DEET, Picaridin, oil of lemon eucalyptus or IR-3535, and be sure to apply to exposed skin when venturing outside during dawn or dusk hours. Wearing long sleeve shirts, pants, socks and shoes also limits the amount of skin exposed to the blood-hungry female mosquitoes (males do not bite).

3. Use screens to your advantage: ensuring that all windows and doors have screens will also keep mosquitoes from coming inside of homes. Inspect and repair all existing screens, as these unwanted house guests need only the smallest holes to be able to get inside.

Mosquito Control continues to conduct both truck adulticiding and routine truck larviciding treatments. Larviciding using Bti is a proactive measure to prevent mosquito breeding at the larval stage and prevents the emergence of adult biting mosquitoes.
