Prevent Bug Bites - CDC Advice
'How can I prevent bug bites when traveling?' Let's see what CDC has to say about it.
Bugs (including mosquitoes, ticks, and some flies) can spread diseases (including Zika, dengue, and Lyme disease), many of which cannot be prevented or treated with a vaccine or medicine. Reduce your risk by taking steps to prevent bug bites. See below for special instructions to protect babies, children, and pregnant women.
Prevent Bug Bites - Use Insect Repellent
Use EPA-registered insect repellents that contain at least 20% DEET (products include Cutter Backwoods and Off! Deep Woods) for protection against mosquitoes, ticks, and other bugs. Other repellents protect against mosquitoes but may not be effective against ticks or other bugs:
- Picaridin (also known as KBR 3023, Bayrepel, and icaridin)
- Oil of lemon eucalyptus (OLE) or para-menthane-diol (PMD)
- 2-undecanone (methyl nonyl ketone)
Find the EPA-registered insect repellent that is right for you. The effectiveness of insect repellents that are not registered with the EPA, including some natural repellents, is not known. For more information, see EPA’s website.
When using insect repellent, follow the instructions on the package and reapply as directed:
- In general, higher percentages of the active ingredient provide longer-lasting protection. However, this increase in protection time maximizes at about 50% DEET.
- If you are also using sunscreen, apply it first, let it dry, and then apply repellent. Do not use products that contain both sunscreen and repellent.
- Do not spray repellent on the skin under clothing.
Consider using clothing and gear (such as boots, pants, socks, and tents) that are treated with permethrin (an insecticide). You can buy pre-treated clothes or treat your own clothes. If treating items yourself, follow instructions carefully. Do not use permethrin directly on skin.
Prevent Bug Bites - **Cover Exposed Skin**
As much as possible, wear long-sleeved shirts, long pants, socks, and a hat. Tuck your shirt into your pants, and tuck your pants into your socks for maximum protection. Some bugs, such as tsetse flies, can bite through thin fabric.
Prevent Bug Bites - Avoid **Bugs Where You Are Staying**
Choose hotel rooms or other accommodations that are air conditioned or have good window and door screens so bugs can’t get inside. If bugs can get into where you are sleeping, sleep under a permethrin-treated bed net that can be tucked under the mattress. When outdoors, use area repellents (such as mosquito coils) containing metofluthrin or allethrin.

Prevent Bug Bites - **Traveling with Children**
Follow instructions for applying repellent on children:
- Do not use insect repellents on babies younger than 2 months old.
- Do not use products containing OLE or PMD on children younger than 3 years old.
- Children should not touch repellent. Adults should apply it to their hands and gently spread it over the child’s exposed skin.
- Do not apply repellent to children’s hands because they tend to put their hands in their mouths.
- Keep repellent out of the reach of children.
For babies under 2 months old, protect them by draping mosquito netting over their carrier or car seat. Netting should have an elastic edge for a tight fit.
Prevent Bug Bites - **Pregnant Women**
Some infections, including Zika, can spread from a pregnant woman to her fetus, so pregnant women should strictly follow steps to prevent mosquito bites while traveling. In the case of Zika, because infection in a pregnant woman is linked to serious birth defects and miscarriage, CDC recommends that pregnant women not travel to areas with Zika outbreaks.
When used as directed, EPA-registered insect repellents are safe and effective for pregnant and breastfeeding women.
