What Is Cedar Fever?

Cedar Fever is an allergic reaction to pollen from the Juniperus ashei tree, commonly known as Mountain Cedar, a type of juniper that has an aggresive seasonal bloom. Cedar Fever is most common in December and January, when pollen counts are at their peak, but cases have been known to begin earlier last through March. Cedar fever is primarily found  Central Texas.

Symptoms of Cedar Fever

Cedar Fever affects people differently and symptoms can include sneezing, runny nose, itchy eyes, cough, headache and sinus congestion. Cedar Fever can easily be confused with the flu or a cold and if they are severe, it is recommended that you consult a health care provider to determine what you may be suffering from and the appropriate treatment.

Preventing Cedar Fever

Experts recommend the following actions to protect yourself and your family against cedar pollen and to minimize the effects of Cedar Fever or other seasonal allergies.

At Home

  • Keep exterior windows and doors closed whenever possible
  • Turn the air conditioner or heater on when pollen levels are high
  • Use a cheesecloth to cover air conditioning vents for filtration of the pollen
  • Change out the filters in your AC system regularly - HEPA filters are recommended
  • Dust regularly with a moist cloth
  • Clean your home with a HEPA filter vacuum cleaner as often as once a week
  • Bathe pets frequently to avoid spreading pollen through your home - cedar pollen can stick to your pets fur


  • Drive with car windows closed
  • Keep the car air conditioner or heater on, in recirculation mode
  • For extreme cases, cover your nose and mouth with a painter's mask
  • If outdoors for a long period of time, be sure to shower and change clothes upon arriving home in order to remove traces of pollen from your hair, skin and clothing
