Hurricane Helene could cause another hatchfest, similar to Florence in 2018.  The pests hatched en masse from eggs lain dormant in soils and debris, some for as long as 2+ years.  Floodwater mosquitos are a common nuisance throughout the state, generally are not a major threat to human health, the large numbers can make outside life irritating at best.
Thankfully, this nuisance or some say threat can be controlled.  Your veterinarian can prescribe a heartworm preventative and calling skeeta.pro will provide further preventative for you and your fur babies.
