"It sounds like it makes sense -- you get two for one," said Nicole Sarrubbo, an associate editor at Consumer Reports. But people should use two separate products, Sarrubbo said, because while sunscreens should be applied liberally and often, "you don't want to do that with bug spray."
People should be cautious about their use of bug spray, to avoid exposure to unnecessary chemicals, she said.
The company also does not recommend using clip-on mosquito-repellent devices. In testing, their protection lasted less than two hours.
Insect repellents should not be applied to infants, and for children, Consumer Reports recommends a repellent with a DEET concentration of no more than 30 percent (the top ranked products have between 15 and 30 percent DEET).
And bug repellents are just be "one of the tools in your toolbox," against mosquitoes, Sarrubbo said.
Other ways to reduce exposure to mosquitoes include: clearing areas with standing water, staying inside during dawn and dusk (peak hours for mosquitoes), and limited use of perfumes and scented products that can attract misquotes, Sarrubbo said.
