The fear of Zika virus has turned bug spray into a must for families. But not every repellent is equally effective against the mosquito that carries Zika. Consumer Reports recently put them to the test.
They recommend products with one of three active ingredients: DEET, at a concentration of 15-30 percent; picaridin at 20 percent; or oil of lemon eucalyptus at a concentration of 30 percent.
And make sure to cover all bare skin.
"So, for example, if you're spraying your arm, you want to make sure you turn your arm and do the underside. You don't want to spray the repellent under clothing but you can spray on your clothing," said Trisha Calvo of Consumer Reports.
Experts say your best bet is to buy those repellents from a drugstore. But they say to stay away from products with natural plant oils that often claim to be family friendly. Those would include citronella, cedar oil and lemongrass. Tests found some of those ingredients fail immediately.
"They really didn't repel the kind of mosquitoes that carry the Zika virus at all," Calvo said.
Something else to look out for-- New York's attorney general says the Zika scare has created a breeding ground for scammers. He's going after companies selling bogus products like wrist bands, patches and even ultrasound devices.
"Some of the marketing campaigns aimed at people seeking to protect their child are absolutely shameless," New York Attorney General Eric Schneiderman said.
Doctors say stick to government-approved repellents and use them frequently.
