Ragweed and other weeds such as curly dock, lambs quarters, pigweed, plantain, sheep sorrel and sagebrush are some of the most prolific producers of pollen allergens

Although the ragweed pollen season runs from August to November, ragweed pollen levels usually peak in Mid September in many areas in the country. In addition, pollen counts are highest between 5 - 10 AM and on dry, hot and windy days. Avoid the outdoors between 5-10 AM. Save outside activities for late afternoon or after a heavy rain, when pollen levels are lower. Keep windows in your home and car closed to lower exposure to pollen. To keep cool, use air conditioners and avoid using window and attic fans. Be aware that pollen can also be transported indoors on people and pets. Dry your clothes in an automatic dryer rather than hanging them outside. Otherwise pollen can collect on clothing and be carried indoors.
