Fall Allergies and Sinusitis

Autumn has arrived, and you don’t feel so good. You can’t stop sneezing and sniffling. The return of cool weather leaves you feeling not invigorated but miserable. What’s going on? You may be suffering from pollen allergy, a.k.a. allergic rhinitis or hay fever. Thirty million Americans do, and symptoms typically flare in fall.

  • Choose a bug spray with a lower concentration of DEET. A spray with 30% DEET is as effective as stronger products.
  • Look for a graphic created by the Environmental Protection Agency that indicates how long the product will protect you from tick and mosquito bites.
  • Apply just enough to cover exposed skin and clothing. Don’t use it under your clothes.
  • Don’t spray directly on your face. Spray it on your hands and pat your face.
  • Don’t apply bug spray near your eyes or mouth. Use just a little around your ears.
  • Don’t use on skin with cuts, sores, or irritation.
  • Use bug spray only in well-ventilated areas. Don’t spray near food.
  • After returning indoors, wash treated skin with soap and water.
  • Avoid products that combine DEET and sunscreen, because the instructions for using the two products are different.

For children:

  • Do not use products with lemon eucalyptus oil on children under the age of 3.
  • Don’t let a small child put on bug spray on their own. Put some on your hands, then use your hands to put it on the child.
  • Don't apply bug spray to a young child’s hands, because they may put their hands in their mouth.

In rare cases, bug spray can cause irritation or allergic reactions, too. If you think you’re having a reaction, stop using the spray. Wash your skin well with soap and water, and call a poison control center.

If you get bug spray in your eyes, flush them with water and call your doctor or poison control center. If you go to the doctor, take the bug spray with you.
