Mosquitoes are swarming in parts of northeast Florida flooded by Tropical Storm Debby.
Biologists say St. Johns County has seen a 35 percent increase in mosquitoes over the last two weeks as a result of the standing water left by Debby's rains.
Whitney Qualls of Anastasia Mosquito Control tells The St. Augustine Record that inspectors planned to step up their spraying Tuesday night and Wednesday morning to try to control the swarms.
Mosquito control officials are urging residents to dump or drain any standing water on or near their properties, because mosquitoes lay eggs in standing water. Vulnerable spots include ditches, flower pots, trash cans, dog bowls, clogged rain gutters or any other open container left outside.
