Allergy Shots in Iowa: What to Know

Top Allergens in Iowa
The most common allergens affecting residents of Iowa, ranked by severity and seasonal impact.
Giant / Short Ragweed (Ambrosia trifida, A. artemisiifolia)
SevereIowa is at the core of the Ragweed Belt, where both giant and short ragweed thrive in disturbed agricultural ground and along corn and soybean field margins. Des Moines ranks among the worst U.S. cities for fall weed pollen.
Dominant fall allergen statewide
Oak / Hickory (Quercus, Carya) Pollen
SevereEastern Iowa hardwood forests along the Cedar, Iowa, and Mississippi rivers are oak-hickory dominant, producing peak tree pollen counts in late April through early May.
Silver Maple / Box Elder / Ash (Acer saccharinum, A. negundo, Fraxinus)
ModerateSilver maple, box elder, and ash open Iowa's allergy season as early as March, with box elder particularly heavy along river valleys across the state.
Timothy / Orchard / Brome Grass (Phleum, Dactylis, Bromus)
SevereCool-season grasses including timothy, orchard, brome, and fescue dominate Iowa pastures, hayfields, and Conservation Reserve Program land, driving heavy summer pollen loads.
Corn Pollen / Agricultural Dust (Zea mays)
ModerateIowa is the number one U.S. corn producer. Mid-summer corn tasseling produces heavy agricultural dust carrying field-mold spores and grass allergens — a documented Iowa-specific exposure.
Alternaria Mold (Alternaria alternata)
SevereIowa harvest dust generates among the nation's highest Alternaria spore counts, spiking during dry, windy late-summer conditions and combine harvesting in September and October.

Why Allergies Are Worse in Iowa
Iowa's position in the Corn Belt and Ragweed Belt, combined with Mississippi and Missouri River valley humidity and intense agricultural operations, creates overlapping tree, grass, weed, and mold seasons stretching from March through October.
Dominant Cornbelt Ragweed Reservoir
Iowa's nearly statewide corn and soybean rotation creates the densest ragweed habitat in the Midwest along field edges and roadsides, with Des Moines ranked among the worst AAFA Allergy Capitals.
Mississippi and Missouri River Valley Mold
Eastern and western Iowa river corridors trap humidity, fueling outdoor mold spores and prolonging weed-pollen residence in stagnant valley air across Davenport, Dubuque, and Sioux City.
Prairie Grass and Hayfield Pollen
Native tallgrass prairie remnants and cultivated brome, timothy, orchard, and bluegrass hayfields drive a strong May through July grass pollen season, intensified during haying operations.
Livestock and Grain Dust
Iowa's large hog, cattle, and grain-handling operations release endotoxin-laden dust and corn and soybean harvest particulates that aggravate asthma and allergic rhinitis, especially in rural counties.
