Avoiding Triggers


Quick links


While there may be no cure for your child’s allergy, there are positive steps that can be taken to reduce the number of allergens in your home. See the Allergy House to help manage indoor allergens.

In the same way that reducing the number of allergens around the home can lower the number and severity of symptoms, avoiding the triggers of allergies and allergic conditions can reduce the number of allergy attacks that your child has.

 If you know what triggers your child’s allergy you can take the following steps to help control their symptoms.

Trigger - Mould and House Dust Mite

  • Always ventilate rooms where there is visible steam and condensation
  • Open windows and doors to increase the airflow and lower humidity
  • Reduce the temperature in rooms
  • Avoid having pot plants (which can grow mould on the soil), or cover the surface of the soil with a layer of pea shingle
  • Throw away old foods
  • Keep fridge and freezer seals clean
  • Dry the fridge well after cleaning
  • Clean obvious areas of mould away
  • Wipe up condensation on surfaces such as windowsills and bathroom walls
  • Always dry clothes thoroughly outside or in the tumble dryer before hanging them in the house.  Avoid drying clothes in the house, if possible, as this will add to the humidity in the home
  • Try to enclose mattresses with barrier covers
  • Wash bed linen at 60 degrees to kill house dust mite
  • Remove soft toys or store them in a box with a lid
  • Have an identical soft toy if it is a favourite so you do not upset your child when you clean it
  • Remove unnecessary soft furnishings, such as cushions and rugs, and consider swapping carpets and traditional fabric covered sofas for alternatives
  • To remove house dust mites from soft toys place them in the freezer for a night to kill them and then wash at 40 degrees to remove the allergen particles.  Alternatively wash at 60 degrees without freezing
  • Let duvets and pillows air by open windows, but beware of outside pollen levels if this is a problem
  • Keep areas dust free and easy to vacuum, such as under the bed
  • Use electrostatic dusters or damp-dust areas to stop dust and house dust mite particles getting into the air as you clean

  • Keep windows closed at these times
  • Wash your child’s hair every day during the pollen season if they have been playing outside
