Look for products that contain an EPA-registered active ingredient such as DEET, picaridin, or oil of lemon eucalyptus. 

If your repellent contains DEET, choose one with up to 30% DEET. A higher concentration can cause skin rashes and is not recommended to use on young children. 

Insect repellents with picaridin offer similar protection as DEET. Repellents that contain 5% picaridin protect up to four hours, while repellents that contain 20% picaridin protect up to 12 hours. 

Repellents made with oil of lemon eucalyptus are not recommended for children younger than 3 years old. Products with 8%-10% concentration protect up to two hours, while products with 30%-40% concentration protect up to six hours.

Most importantly, read the label and follow directions. Do not spray insect repellent directly in the face. A parent should spray repellent on their hands and then apply to a child’s face.
 

We want to do our best to keep babies safe. It’s best to avoid insect repellent and cover them up with light, long-sleeved clothing. A mosquito net can also provide additional protection.
 

Using a product that contains both sunscreen and insect repellent is not recommended in children. Because sunscreen needs to be reapplied every two hours, a combo product could expose your child to too much insect repellent. It’s best to keep the two products separate. Apply sunscreen first and insect repellent second.
 

Dress your child in light clothing that covers their arms and legs. Mosquitoes like to bite around the wrist and ankles, so it’s wise to cover those areas. And yes, it’s okay to spray insect repellent on your clothes, but keep in mind that DEET products can potentially affect fabric with a plastic component (ex. Rayon, spandex). It is also not recommended to apply insect repellent underneath clothing. 

You can also use 0.5% permethrin to treat clothing or buy permethrin-treated clothing. Permethrin is an insecticide that kills or repels mosquitoes.
