The Most Likely Cause

These symptoms of allergy are common to a range of medical conditions including allergies of various kinds (grasses, pollens and dustmites the most common), Asthma and Atopic Dermatitis better known as Eczema.

To establish the cause of your symptoms of allergyand facilitate treatment, professional medical advice is advisable. However, extensive studies have suggested that a very common cause of such symptoms is a Dustmite Allergy. It is estimated that some 80% of the population has some form of Dustmite Allergy and even more importantly, around 40% of all Asthma attacks* are triggered by a Dustmite Allergy.

What is Dustmite Allergy

Dustmites are microscopic arachnids that live and breed in our homes. They feed off the “dander” such as hair and skin that we and our pets shed constantly. They particularly love a warm, damp environment such as bedding, carpets and soft furnishings. It is impossible to permanently rid our homes of dustmites.

Unfortunately, in cleaning up after us they leave faeces behind which contain allergy causing proteins. When the faeces are disturbed, a cloud of allergens floats up which we breathe in or which settles on our skin.

Our body recognises this invader as a threat and produces histamines to reject this attack. This causes your symptoms of allergy and discomfort.

If your symptoms of allergy are often more obvious in the morning as you wake or as you lie down to sleep, this is a key sign that dustmites are the trigger for your symptoms of allergy.


Here’s what one lady experienced with her allergy symptoms …

Approximately 6 months ago I was suffering with severe nasal congestion and, scratchy eyes when first waking up in the morning.

After purchasing eye drops and using the occasional antihistamine I was starting to wonder if the problem could have been dustmites.

Not sure about what to do I went on the internet and discovered the product Dustroy. I then purchased some and after applying to my bed linen, mattress cover, pillow etc., I noticed that from the first night there was quite a difference the following morning.

There was a marked reduction in the symptoms I had been experiencing and now it has been over 3 months since I last applied it and I noticed the symptoms occurring again.

So I have purchased more and noticed again, a significant reduction after the first night of use. I still have hayfever, but I think it was being complicated by the dustmite issue.

A Simple Home Test

It is simple to establish if dustmite allergy is causing or aggravating your problem. Obtain a sample of the allergy control spray “Dustroy” and follow these three simple steps:

  • Choose an area such as a your bedroom. Thoroughly vacuum the mattress and other non-washable bedding. Wash all sheets, pillows, pillow cases and soft furnishings. Dust everywhere with a damp cloth.
  • Lightly but thoroughly spray all the surfaces you have prepared with Dustroy. Avoid spraying hard or non-absorbent surfaces since they do not harbour dustmites.
  • Allow 30 minutes for Dustroy to dry.

What to Expect

If your allergy symptoms are respiratory, you will notice an immediate reduction in your symptoms when you go to bed or when you get up in the morning. There will be a reduction in your itching, no more sore throat or itchy runny eyes, coughing or sneezing.

If your symptoms are skin rashes or other forms ofeczema, it may be a few days before you start to enjoy relief from your symptoms, since even though the allergen has been removed, the body has to heal the existing damage that has been caused on the skin. The ‘itching’ symptom of allergy will reduce almost immediately using Dustroy.

If there is no change in your symptoms of allergy after a reasonable time, you either do not have a dustmite allergy or there are other complicating factors or allergies involved. If you have not already done so, you need to seek professional medical advice.

NB See Joanne Allis’s email (on this page) of what she experienced with her symptoms of allergy. This shows typical results after using Dustroy.

Regular Treatments

To maintain control of your symptoms of allergy, it is important to follow a regular routine of treatments. One 500ml bottle of Dustroy will cover up to 20 sq.mts.  with a light spray. Dustroy is bio-degradable but will remain effective for up to 8 weeks.

  1. Before treating mattresses, pillows, carpets and soft furnishings give them a thorough vacuuming or wash the linen in hot water (above 60◦c)
  2. Lightly spray all the areas you have cleaned with Dustroy and allow to dry.
  3. Make up your bed as per usual with the treated linen
  4. Re-spray bed linen after washing. We find it easier while they are still on the clothes line.
