Dust mites and their faeces are the most
significant triggers of allergic respiratory problems. They proliferate
in mattresses, bedding, carpets, curtains, upholstered furniture,
clothes and soft toys, feeding on skin flakes and mold. Their
idea of the heaven is the cosy temperature and high humidity of
the average bed – no wonder a double bed can house up to
10 millions contented mites and up to 2.5 billion fecal pellets!
Equally shocking that up to percent of the weight of the old pillows
can be made to dust mites and faeces. Here are tips for avoiding
contact with dust mites:
| 1. |
Encase pillows and mattresses in zippered mite-proof covers
to prevent contact with mites and to remove their access to
food source (skin flakes). |
| |
|
| 2. |
Wash bedding in hot water (60°C) every one to two weeks
-mites get killed only at temperatures above 55°C. |
Alternatively, use an anti-mite washing
additive if cold water washing is desirable.
| 1. |
If possible replace all upholstered furniture with "wipeable"
materials such as wood, vinyl, or leather furnishings |
| |
|
| 2. |
Replace line drapes with wipeable shades or light weight
hot water washable curtains |
| |
|
| 3. |
Keep carpeting to a minimum and replace with small hot water
washable rugs |
| |
|
| 4. |
Alternatively, treat all upholstery, curtains and carpets
every 4 monthly with anti-mite solutions |
| |
|
| 5. |
Reduce indoor humidity to below 50%RH by using dehumidifiers
and air-conditioners, as mites cannot survive at low humidity
levels. Remember to keep you r air-conditioners mold-free
by using anti−mold sprays every 3 monthly |
| |
|
| 6. |
Remove dust collectors by storing books, magazines and knick-knacks
in enclose bookcases or sealed boxes |
| |
|
| 7. |
For your child, allow only soft washable soft toys |
Wash them in hot (60°C) water every 2 weeks.
When house cleaning, use a HEPA−high filtration
vacuum cleaner, as this will not recirculate the fine mite debris
back into the air. Also use a damp or electrostatic cloth for
dusting to avoid stirring up the dust.
Making changes to reduce allergens in your
home may take time. You can start by making a priority list of
changes to make over several months. These changes can create
an indoor environment that is less allergenic, easier to clean
and healthier.
