When Is Indiana Allergy Season?

Indiana has a typical allergy season thanks to the presence of all four seasons. Winter comes and rids the state of pollen allergies for a few months, but pollen allergies will still be a problem during the other three seasons — and indoor allergies can cause issues all year.

Allergens by Season

Residents will face seasonal allergies in summer, spring, and fall. Here is a quick breakdown of some of the most prominent allergies during each season.


Summer is when grass allergies start for Indiana residents. Some grass allergy triggers to watch out for include bent, fescue, orchard, and Johnson grasses. Grass allergies usually start near the end of May and end before August.


Fall is weed allergy season for Indiana residents. This means pollen from ragweed, wormwood, cocklebur, and amaranth is in the air. This season begins in mid-August and ends after winter’s first hard freeze.


Indiana residents can count on cold winters, which means pollen allergies are done until spring rolls around. Indoor allergens like dust mites, mold, and pet dander could still be a factor during the winter.


Spring is tree allergy season. The most common causes of tree allergies in Indiana include oak, birch, elm, ash, maple, hickory, walnut, willow, and mulberry. This season begins in late February or early March and usually tapers off in May.

Common Allergens

Residents of Indiana can expect seasonal allergies from spring to late fall. These allergies are usually due to tree, weed, and grass pollen. Indoor allergies can be a year-round problem with dust mites, pet dander, and mold being common culprits.

Common Symptoms

Indiana residents can expect the following allergy symptoms:

  • Runny nose
  • Coughing
  • Congestion
  • Sneezing
  • Headaches
  • Scratchy throat
  • Itchy eyes
  • Watery eyes
  • Hives
  • 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 very difficult to find the source of your allergies in Indiana. An educated guess can help you determine if you have grass, tree, or weed allergies based on what time of year you have allergy symptoms, but you might not be able to pinpoint the exact pollen type. Also, the intersection of allergy seasons means you may make the wrong assumption. Many people are even allergic to multiple types of pollen. An allergy test can make things clear, and Wyndly makes allergy testing convenient with our at-home test. Buy your at-home test from Wyndly today.

Let’s explore 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, and 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.

Treatment and Remedies

Allergy symptoms can be miserable to put up with, but there are various ways you can manage your symptoms. There are even methods for treatment that can bring you lifelong relief from allergies. Let’s take a look at some of the available options.

Limiting Exposure

It’s always good to try limiting your exposure as the first step to symptom management. If you’re able to avoid your allergens, you may be able to keep your symptoms at a manageable level. Of course, pollen isn’t always easy to avoid, but there are several ways you can keep exposure to a minimum.

  • Keep windows closed: Leaving your windows open during allergy season can let pollen in your home. Keeping your windows closed and running the A/C makes it harder for pollen to get through.
  • Watch pollen levels: You can check the daily pollen count using a website or app. If pollen levels are high, try to stay inside as much as possible.
  • Mask up: But if the pollen count is high and you need to go outside, a dust mask is a good way to keep pollen out of your airways.
  • Vacuum and dust: Using a HEPA filter vacuum is a good way to remove pollen from your floors. It’s also recommended to dust hard surfaces with a wet rag.
  • Do laundry often: Remember to throw your clothes in the laundry after being outside, since pollen can stick to them. Doing laundry often will help keep pollen off your clothes and out of your house.
  • Shower often: Pollen can stick to your body and hair too. Remember to rinse off after being outside. Washing your hands and face works if you’re not home or are in a rush.
  • Remove your shoes: Remember to take your shoes off when you get home so you don’t track in pollen.


While limiting your exposure is recommended, it’s not always the ultimate solution to get rid of your allergy symptoms. Many people get additional support from over-the-counter allergy medications for short-term symptom relief. Some common options you can try are antihistamines, nasal sprays, eye drops, and decongestants.

Sublingual Immunotherapy

The remedies above are just ways to manage your symptoms. If you want to treat your allergies and find long-term relief, you may want to try sublingual immunotherapy. Sublingual immunotherapy is a form of allergy treatment that introduces gradually increasing doses of an allergen to your immune system with drops or tablets that are administered under the tongue. Over time, this trains your immune system to ignore or tolerate these substances, ridding you of allergy symptoms. Unlike allergy shots, sublingual immunotherapy is painless and can be taken at home.
