(CNN) Aerial spraying for Zika-carrying mosquitoes, which happened in the predawn hours on Friday, is bugging out residents of Miami Beach, Florida. So far there have been 56 locally transmitted cases of the Zika virus in Florida , which has 20.6 million residents. A few days later, in an unprecedented move, the CDC announced a travel warning, advising pregnant women not to visit that area. Aggressive mosquito-control measures were taken, including mosquito spraying in the area. Since the variety of mosquito that carries Zika is most active predawn and at sunset, all spraying must take place at those times.
