Use an outdoor insect spray and wear long-sleeved shirts and long pants when you travel to an area with Zika. Remember to protect your children as well!

Use insect repellents that are registered with the Environmental Protection Agency (EPA). This is safe for pregnant and breastfeeding women. Always use as directed. 

Do not spray repellent on the skin under clothing. If you are also using sunscreen, apply sunscreen first and insect repellent second.
