An allergen is something in your environment that can cause allergy symptoms of
sneezing, itchy watery red eyes, runny nose and nasal congestion.
Outdoor allergens have certain seasons of the year when they are present. Pollen and
mold spores are carried by the wind. Some pollen can travel hundreds of miles. This is
why warm, dry, and windy weather often increases allergy symptoms. Since pollen and
mold are carried by the wind, it will not help to remove plants or trees in your yard.
