Experts recommend applying sunscreen first, then bug spray, not the other way around. And even if you wear bug repellent clothing, Consumer Reports recommends also using bug spray for greater protection.
In addition, the Centers for Disease Control and Prevention recommends wearing long-sleeve shirts and long pants, and staying in places with air conditioning and window and door screens to keep mosquitoes outside.
An experimental vaccine for the Zika virus is due to begin human testing soon, after getting the green light from U.S. health officials.
According to Consumer Reports, a number of insect repellents on the market can stop the mosquitoes that transmit the dangerous virus, as well as another mosquito-borne illness, West Nile virus. They put 16 insect repellents to the test to see which ones are the most effective.
"In a laboratory, very brave volunteers put their arms into a cage full of 200 disease-free mosquitoes and we use two types of mosquitoes," Trisha Calvo of Consumer Reports told CBS New York. "One is the Culex mosquito that carries West Nile and the other is the Aedes mosquito that carries Zika."
The results? "We found three ingredients that are safe for everyone to use, even pregnant women, and are very effective. And those are Deet, oil of lemon eucalyptus, and Picaridin," Calvo said.
Sawyer's Fisherman's Formula Picaridin got top results in Consumer Reports testing, keeping mosquitoes away for up to eight hours.
Other top performing repellents on the list include:
- Ben's 30% DEET Tick & Insect Wilderness Formula
- Natrapel 8 Hour, with 20 percent picaridin
- Off! Deepwoods VIII, with 25 percent DEET
- Repel Lemon Eucalyptus, with 30 percent lemon eucalyptus
- Repel Scented Family, with 15 percent DEET
Consumer Reports advises skipping most repellents made with natural plant oils such as lemongrass or citronella, which were not very effective in their testing.
