Attention Florida homeowners! 
- Were your neighbors foreclosed on in the past few months?
- Are there houses in the area that are obviously vacant?
- Do these vacant home have pools?
Chances are that this could affect your family's health..!! How so? you may ask..
Truthfully, I never considered the idea of a vacant home nearby being a problem or a health issue for myself or my family. After finding some information online, it seems that there are possible dangers lurking nearby.
Vacant homes with pools that are not cleaned, filtered and turning green create an ideal environment & breeding ground for mosquitoes and other arthropods that can carry, amongst other things, the West Nile Virus. It doesn't mean that every mosquito out there has it, but potentially, they can carry it.
quoting The Florida Department of Health's website:
"Arboviral diseases are those that are caused by an arthropod (insects such as mosquitoes, ticks, mites, and midges). These include West Nile virus, Eastern Equine Encephalitis virus, and St. Louis Encephalitis virus, which are all mosquito-borne diseases found in Florida."
So it a major issue in Florida? I'm not sure, but I don't think so. I only see one county in Northern Florida with an alert. (see PDF map)
-Would I buy a few extra cans of 'OFF' next time I go to the supermarket if there are vacant homes in the area? -Yes, it couldn't hurt to have some extra repellent to be on the safe side.
Anywhere there is standing water, there is a potential for mosquito breeding. Abandoned or empty homes can have multiple areas in the backyard that can hold standing water. These include car tires, flooded plant pots and old plastic/decorative ponds jsut to name a few.
How does that saying go? -An ounce of prevention is better than a pound of cure.
