About Spring Allergies

While the start of spring is pretty much the same every year (March 19th, 20th, or 21st), the start of spring allergy season is much harder to anticipate. In some parts of the country, spring allergy season can start as early as February and may last well into summer!

So even though it may not technically be "spring", your sneezing, nasal congestion, itchy, watery eyes and runny nose could very well show up earlier than expected, and stick around long past their welcome. But that doesn't mean you have to let spring allergy season catch you off guard! 

Get the inside scoop on spring allergies—what causes them, what they do, and more importantly, what you can do about them. 

Causes of Spring Allergies

Tree Pollen

During late winter and early spring, dormant trees bounce back to life and start releasing allergy-inducing pollen into the air. Some common culprits include birch, cedar, hickory and walnut.

Grass Pollen

Of all the various kinds of grasses blanketing lawns, fields and gardens, only a small number can be blamed for causing allergy symptoms. Timothy, Bermuda and Kentucky Blue are some of the most common allergy-provoking grasses.


Mold thrives in damp indoor and outdoor environments such as leaf piles, rotten logs, basements and bathrooms. Unlike pollen, mold doesn't die with the first frost; instead, it stops growing and lays dormant until the weather starts to warm.

Dust Mites

Dust mites, or more specifically, dust mite waste, is a common indoor allergen that can be found in many places around the house—furniture, carpets, bedding and stuffed toys.


One of the most common, and most bothersome, symptoms reported for allergies is nasal congestion.

Also on the list are: 

  • sneezing
  • itchy, watery eyes
  • itchy nose
  • runny nose

Pollen Count

No matter what you're up to this spring, checking the pollen count for wherever you’re headed can make a real difference. 

Spring Cleaning

There's nothing like a fresh, clean house to mark the beginning of spring. Before you get out the dust cloth and vacuum, make sure you have a strategy for how to tackle your cleaning to reduce indoor allergens.
