Apply repellents only to exposed skin and or clothing as directed on the label. Do not use repellents under clothing.
Never use repellents over cuts, wounds or irritated skin.
Do not apply to eyes or mouth, and apply sparingly around ears. When using sprays, do not spray directly on the face, spray on hands first and then apply to face, then wash your hands.
Do not allow children to handle the product. When using on children, apply to your hands first and then use the material on your hands to apply it to the child. You should not apply materials directly on a child hands since the chance is great that they will rub it into their eyes or mouth.
Use just enough repellent to cover exposed skin and or clothing. Heavy applications and saturation are generally unnecessary for effectiveness. If biting insects do not respond to a thin film of repellent, apply a bit more.
After returning indoors, promptly wash treated skin with soap and water. This is particularly important when repellents are used repeatedly during the day or on consecutive days. Also, wash treated clothing before wearing it again.
If you or your child gets a rash or other reaction from an insect repellent, stop using the repellent, wash the repellent off with mild soap and water, and call a local poison control center for guidance. If you go to the doctor because of the repellent, take the repellent with you to show the doctor.
**Note that the label for products containing oil of lemon eucalyptus specifies that they should not be used on children the age of three.
