When Is Iowa Allergy Season?

Iowa’s allergy season follows the typical pattern. Allergies will start in early spring when trees start producing pollen, and fall allergies will end after winter’s first hard freeze. Once winter comes, outdoor allergy season takes a hiatus.

Allergens by Season

Depending on the season, there will be different types of pollen in the air. There are several allergens to watch out for.


Summer is Iowa’s grass allergy season. Grass allergies in Iowa are typically from ryegrass and bent, fescue, timothy, orchard, and brome grasses. Grass allergy season usually starts in May and ends in July.


Fall is weed allergy season in Iowa. Weed allergens to watch out for include lamb’s quarters, ragweed, wormwood, and sagebrush. Weed allergies start at the end of summer and end after the first hard frost.


Seasonal allergy sufferers can breathe easy during the Iowa winter. Indoor allergies can pose a problem, though, so keep this in mind if you’re still having allergy symptoms.


In spring, it’s tree allergy season for Iowa residents. Tree allergies in Iowa usually are a response to maple, hickory, ash, oak, willow, mulberry, and walnut trees. Tree allergy season starts around late February or early March and ends in May or June.

Common Allergens

Iowa residents have tree, grass, and weed pollen as their main seasonal allergens.

Common Symptoms

Iowa residents can expect the following allergy symptoms:

  • Runny nose
  • Coughing
  • Congestion
  • Sneezing
  • Headaches
  • Scratchy throat
  • Itchy eyes

  • Aggravated asthma symptoms

As always, reactions will vary from person to person, but in general, allergies will cause one or more of these symptoms to occur.

Testing and Diagnosis

It can be incredibly difficult to self-diagnose airborne seasonal allergies. There is so much pollen in the air, that it’s almost impossible to pinpoint the specific culprit — and that’s without considering indoor allergies. With an allergy test, you can find out your exact allergens so you can avoid them and treat them properly. Wyndly’s at-home test takes the inconvenience out of allergy testing by sending the test right to your door. Buy your at-home allergy test from Wyndly today.

Let’s examine how different allergy testing options work.

Old-Fashioned Method: Skin Prick Test at Your Doctor’s Office

Skin prick testing requires you to go to the doctor to find out your allergen triggers. It’s often uncomfortable, and it takes time out of your day. You’ll go to the doctor’s office, they’ll administer a test where they prick or scrape your skin with a needle tipped with different allergens, and then they’ll observe the areas they pricked for itchiness, redness, or swelling. All in all, it’s not a pleasant experience. Instead, you can save yourself time and pain by getting an at-home test.

Modern and Efficient At-Home Method

  1. Order Wyndly’s at-home allergy test. We ship our CLIA-certified test straight to your door.

  3. Receive your personal allergy profile. Our doctor will interpret your results, create an allergy profile, and walk you through a treatment plan.

Treatment and Remedies

Instead of putting up with your allergies throughout allergy season, you can use remedies and treatments to reduce symptoms. There are several you may want to try.

Limiting Exposure

Limiting your exposure to allergens is a good first step. Here are some ways you can keep exposure to a minimum.

  • Remember to check the pollen count: Find a website or app that can reliably tell you the pollen count for your area. If the pollen count is high for your allergen, you should try to stay indoors. If you can’t, be sure to wear a mask, sunglasses, and hat when you go outside.
  • Clean your home: You’ll want to make sure to clean your home more frequently during allergy season. Using a vacuum with a HEPA filter and dusting with a wet rag will be your best tools for reducing pollen levels.
  • Do your laundry: Remember to do laundry often during allergy season, since pollen can easily stick to your clothes and bedding.
  • Cut grass, trim trees, and remove weeds: Reduce pollen levels in your yard by cutting grass short, trimming tree branches, and removing weeds.
  • Shower after being outside: If you’ve been outside, it’s a good idea to shower and get pollen off. Washing your hands and face well can be a quick substitute.
  • Keep windows shut: Don’t open your windows during allergy season, as that can let pollen in. Use your A/C instead, and install a HEPA filter if possible.
  • Take off your shoes: When you get home, take off your shoes to avoid tracking pollen in.


While limiting exposure can be helpful, it might not be enough to provide complete relief. Over-the-counter allergy medications can be useful for providing temporary relief from several common symptoms. The most common options include antihistamines, eye drops, nasal sprays, and decongestants.

Sublingual Immunotherapy

Instead of just managing allergy symptoms, there are ways to treat your allergies at the source. The safest and most effective way to treat allergy symptoms is with sublingual immunotherapy. Sublingual immunotherapy introduces small, gradually increasing doses of your allergen to your immune system with liquid drops or tablets. This retrains your immune system over time to ignore these allergy triggers instead of responding with an allergic reaction. Unlike allergy shots, sublingual immunotherapy can be taken in the comfort of your home, and it doesn’t require painful needles.
