Must be smart and spray and pregnant women shouldn't risk being around it but it will be in the US very soon. Dozens of states have the mosquitoes that will be carriers of the virus. Just two weeks away and two cans of Deet packed. Also great idea to carry a couple of packs of Off wipes with you at all times. Perfect when you forget to spray or when you find yourself on the sand at sunset and the sand fleas come out!!
