Stay Protected

Depending on the mosquito population in your area, it may be more important to wear repellent for your morning walk than for dinner on the porch, but play it safe and use some whenever you're heading outside. For instance, Aedes aegypti, the main species responsible for Zika and chikungunya (a painful virus that swept through the Caribbean in 2015), bites primarily during the day, while a West Nile–spreading cousin attacks mostly at night.
