Cold temperatures cause mosquitoes to die or go into hibernation, but because we live in hot SWFL and temperatures are well above 60 degrees for most of the year, mosquitos are prevalent and can easily cause diseases, such as the Zika virus linked to birth defects. One table spoon of water can give mosquitos a breeding ground to reproduce up to 300 mosquitos. It is important for standing water throughout your home to be removed to prevent further breeding.
