Allergies are becoming increasingly commonplace and around 44% of adults in the UK have at least one allergy.

Some of these allergies might actually be caused within the home.

In this blog post I will take a look at what might be causing your indoor allergy symptoms and what you can do about it.

What could be causing allergies in my house?

If you only have allergy symptoms within your home then it could be a house dust mite allergy.

A dust mite allergy is caused due to an allergic reaction to the waste caused by house dust mites. 

Dust mites might be present in your bedding and cause an issue at night time or make you very tired in the morning.

They aren’t only in beds though.  You can find dust mites on carpets, soft toys and soft furnishings.

It’s not the dust mites themselves that cause an allergy, but their faeces and shed skin.

What are the symptoms of dust mite allergy?

Like with hayfever and colds, dust mite allergy can cause the following symptoms:

  • blocked or runny nose
  • itchy or watery eyes
  • headaches
  • sore throats
  • tiredness in the morning
  • coughing
  • sneezing
  • skin reactions
  • breathing issues

If you have asthma then you are more likely to suffer with a dust mite allergy.

To see if your symptoms might be an allergic reaction, you can take an at-home allergy test.

What else can cause allergies in the home?

There may be some other causes of your allergy symptoms within the home:

  • Pet allergy –  If you have a pet allergy then you may find your symptoms are worse in your home if you have a pet.  This is due to the animal dander collecting indoors.
  • Mould allergy – spores of mould can trigger an allergy.
  • House dust – a mixture of components which can cause allergies.
  • Pollen – it can get indoors too and trigger your hayfever allergy.

How do I get rid of allergens in my home?

It can be hard to get rid of all the allergens in a home, but getting rid of carpets and opting for a hard floor which can easily be cleaned is one solution.  Make sure you regularly vacuum the hard floors to keep dust and allergens at bay. 

Ultimately, keep dust at bay by dusting regularly and using a damp cloth or cloth with spray to dust surfaces, rather than simply spreading it around with a duster.

Change bedding regularly, use protective dust proof covers, vacuum the mattress and wash bedding at 60 degrees Celsius.

Dust mites like humid environments, so consider a dehumidifier if you have a particularly humid house.  A dehumidifier will also tackle any mould issues and help relieve a mould allergy.

You can also use HEPA filters which must remove 99.97% of particles larger than 0.3 micrometres which will capture dust mites and trap their waste.  These filters can be used in your vacuum and on any air conditioning units you have at home.

Check out these tips to improve indoor air quality.  We spend 90% of our time indoors nowadays according to Allergy UK and we require good indoor air quality for optimal human health, including preventing allergies and reducing symptoms.

The Mayo Clinic also has an extensive guide on how to allergy-proof your home.

How do I find out if I have an indoor allergy?

Many of the symptoms of indoor allergies are similar to common colds and you may not realise you actually have an allergy unless more symptoms present themselves.

To see if you have an allergy then it’s really easy to take a home allergy test from a company such as Klarify.  You can find their home allergy testing kits at 

Once you know you have an allergy then you can do something about it!  You can take steps to reduce the allergens in your home.  If your symptoms are bad then you can take the results of your allergy test to your doctor to seek further advice and a treatment plan.
