Common Allergens in The Home

That’s a lot of people battling everything from itchy eyes to severe swelling! Thankfully, allergy prevention can be simple. Know which allergens are causing your issues and where to find them in your home. Here’s how to identify the six most common causes of indoor allergies:

House Dust

House dust is the most common allergen in the home. It’s a combination of skin flakes, hair, dust mites, animal dander and other tiny particles that can trigger asthma and allergies. House dust can be a problem for people of all ages (as well as for pets).

In addition to being an irritant for those with asthma and allergies, house dust also has been linked to infections because it may carry harmful bacteria or viruses such as influenza virus or those causing pneumonia.

Mites are tiny insects that live in the home. They are often not seen and can be found in pillows and mattresses. They feed on human skin cells, causing itchy rashes when they bite. Mites are often found in large numbers, but they don’t bite humans unless they feel threatened or disturbed.

Dust Mites and Clean Carpets and Upholstery

Mites need moisture to survive, so they’re more common in humid climates such as Florida and Texas. Heat affects the mite population because it makes it easier for them to stay active year round.


Mold is a type of fungus that grows in damp and humid environments. It is found throughout the home, including the bathroom, kitchen and garden.

Several Type of Common Household Molds

Mold spores commonly cause eye, nose and throat irritation as well as asthma symptoms. In some cases, mold exposure can cause more severe reactions such as infections or lung disease.

Pet Dander

Pet dander is the skin flakes of animals. Cats, dogs and birds are the most common culprits but it can also be found in other pets such as rabbits and guinea pigs. The amount of pet dander an animal produces depends on its breed and age, as well as environment conditions such as humidity or temperature.

Pets and Dander

Dander is a common trigger for asthma because it is inhaled into your lungs when you breathe. It can also cause allergic reactions. Touching or eating contaminated surfaces that have been exposed to animal fur, saliva or urine can trigger them.

Pet dander is often found on the fur of your furry friend. Even if you don’t see any evidence of pet hair around your home there may still be small amounts present. Dander can be in the air which will eventually settle onto floors, carpets etcetera over time


Pollen is one of the most common allergens in the home. These tiny particulates can be found in the air outside, but also drifts through open windows and doors. Allergens such as pollen are carried by wind currents, so if you live near an area with lots of trees or grasses (even if they’re not your own), you may have to deal with pollen as an indoor allergen.

Pollen and Allergens

While pollen allergies aren’t usually serious enough to warrant a trip to an emergency room, they can cause unpleasant symptoms. Symptoms including sneezing, runny nose and congestion. If you notice that your allergy symptoms appear at certain times of year or when you’re around plants like grass or flowers, then it’s likely that you have a seasonal allergies.

Chemicals and Irritants

Common chemicals and irritants in the home include:

  • Cleaning products, including dishwasher detergent, laundry detergent and air fresheners. These can cause allergies or asthma if you’re exposed to them on a regular basis. As an added bonus, they may also cause skin irritation or rashes if used improperly!
  • Glue from paper products such as envelopes and glue sticks. If you touch your face after touching these materials it could lead to an allergic reaction like hives or swelling of the lips.

House Dust The most common allergen in the home is house dust. It’s comprised of tiny particles less than 100 microns in diameter. It contain dead skin cells, dandruff flakes and other human body parts. These microscopic particles can trigger asthma attacks or allergic reactions when they become airborne or enter your nose or mouth.

What to Do About Common Allergens?

While it may not be possible to completely eliminate allergens from your home, there are steps that can greatly reduce their presence. Thorough dusting, vacuuming and regular cleaning can go a long way toward keeping everyone in the house healthy. Yearly spring cleaning and carpet cleaning services also reduce common allergens in your home.

Keeping pets out of bedrooms and making sure they’re well-groomed at all times will help prevent pet dander from triggering allergic reactions.
