Using Insect Repellents Properly

The Maine Board of Pesticides Control recommends the following precautions when using insect repellents:

  • Repellents should only be applied to exposed skin and/or clothing (as directed on the product label). Do not use under clothing.
  • Never use repellents over cuts, wounds, or irritated skin.
  • Do not apply to eyes and mouth, and apply sparingly around ears. When using sprays do not spray directly onto face; spray on hands first and then apply to face.
  • Do not allow children to handle repellents, and do not apply to children's hands. When using on children, apply to your own hands and then put it on the child.
  • Do not spray in enclosed areas. Avoid breathing a repellent spray, and do not use it near food.
  • Use just enough repellent to cover exposed skin and/or clothing. Heavy application and saturation is unnecessary for effectiveness; if biting insects do not respond to a thin film of repellent, apply a bit more.
  • After returning indoors, wash treated skin with soap and water or bathe. This is particularly important when repellents are used repeatedly in a day or on consecutive days. Also, wash treated clothing before wearing it again.
  • If you suspect that you or your child are reacting to an insect repellent, discontinue use, wash treated skin and then call the Northern New England Poison Center at 1-800-222-1222. If/when you go to a doctor, take the repellent with you.
