Winter in Australia means closed windows, heating on, and beds that stay warm all day — exactly the conditions dust mites love. If you're waking up congested, sneezing more indoors, or noticing irritated skin, your mattress and bedding are the first place to look. Here's how to deep-clean them properly.
Why Winter Is Peak Dust Mite Season Indoors
Dust mites feed on shed skin cells and thrive in warm, humid, undisturbed fabric — mattresses, pillows, doonas, sofas and carpet. In winter we ventilate less and wash bedding less often in cold weather, so populations spike. An average mattress can host millions of them, and their droppings are one of the most common indoor allergy triggers.
The Winter Deep-Clean Routine
1. Wash bedding hot, weekly. Water above 55°C kills mites. Doonas and pillows need it too, not just sheets.
2. Vacuum the mattress itself — with the right tool. A standard vacuum head glides over fabric without extracting what's inside it. A dedicated dust mite remover vacuum combines strong suction with high-frequency tapping that vibrates mites and droppings out of the fabric, plus UV sterilisation of the surface. Run it slowly over the mattress, pillows and sofa cushions every week or two through winter.
3. Hit the gaps. Mattress seams, bed frames and skirting boards collect the dust that feeds mites. A slim crevice tool on your regular vacuum gets right into them.
4. Drop the humidity. Mites can't survive below about 50% humidity. A small dehumidifier in the bedroom makes the whole room hostile to them.
