A mite is not an insect
It has eight legs rather than six, and it is about a third of a millimetre long. You will not see one by looking at the mattress.

Dust Mites in Your Mattress, and What Cleaning Can Change
Dust mites are not insects and not a sign of a dirty home. They live on shed skin and humidity, and a Singapore bedroom at around 82% relative humidity is close to ideal for them. This page is about what a clean can change, what it cannot, and why the health claims deserve a second look.

Five things to know about the mites you cannot see
Food is shed skin
The food is skin scales people leave behind, not visible dirt. A mattress collects them in the cover and the seams, where a vacuum can reach.
Humidity is the thermostat
Mites take water from the air. Singapore relative humidity sits near 82% most of the year, which is close to ideal for them.
Two mites dominate here
Blomia tropicalis and Dermatophagoides pteronyssinus are the two names a Singapore allergy test usually reports.
The allergen outlasts the mite
Mite bodies and faecal material carry the allergen. Killing a mite does not take that material out of the bed.
Three conditions keep a mite population going
A mattress clean deals with what is in the mattress. Mites depend on three things, and only one of them is in the bed.
- Food: shed skin scales collect in the cover and the seams.
- Humidity: at around 82% in Singapore air, mites do not dry out.
- A clean removes mites, dust and allergen from the surface it reaches.
- What it cannot change: the air, the shed skin, and next month.
Arlian and colleagues found that keeping mean daily relative humidity below 50% restricts population growth, even when humidity rises above 50% for two to eight hours a day. Singapore air spends most of the year well above that line.
Mites also have high reproductive potential. Unless a reduction is thorough, densities return to high levels quickly when food and humidity remain, so a clean is judged by what it removes and what it changes, not by a single count on the day.
How to get rid of dust mites, and the two that live here
Dust mites Singapore households react to are usually two species, and the local allergen evidence is more specific than a generic mite spray suggests. Among 124 Singaporean rhinitis subjects, 50% were positive to Blo t 5 and 43% to Der p 1, and sensitisation to Blo t 5 was more prevalent than to Der p 1 or Der p 2.
That matters because the two allergens are not interchangeable. Blo t 5 comes from Blomia tropicalis; Der p 1 comes from Dermatophagoides pteronyssinus. A test or a product aimed at one does not automatically cover the other, and an allergen measured in a dust sample is not the same thing as a live mite count.
The practical answer is less exciting than a spray. Remove what the fabric holds with a vacuum and a hot wash where the care label allows it, keep the humidity down, and use a sealed encasement if allergy is the concern. Then repeat, because the room refills the bed.

There is no permanent removal, only control. That is not a sales failure; it is what the biology allows, and it changes what a clean is worth to you.

What each measure actually changes
A mite treatment is often sold as one idea. These are different measures with different targets, and the evidence for each is not the same.
- A HEPA vacuum
- Removes dust, mites and allergen that the nozzle reaches. Seams and deep foam are less certain.
- A hot wash of bedding
- Removes allergen from sheets and pillowcases. The care label sets the temperature; the mattress itself is untouched.
- A mattress encasement
- Traps mites and allergen inside and keeps new ones out. It is a barrier, not a clean.
- Humidity under 50%
- Restricts population growth, but the low level has to be held for a long time. An hour of air conditioning is not that.
- Mite reduction for eczema
- A Cochrane review could not determine clear implications for practice from very low-quality evidence.
- Mite control for asthma
- A Cochrane review of 55 randomised trials with 3,121 people with asthma found no effect on asthma outcomes, encasings included.
A clean can remove dust and allergen from the surface it reaches. It cannot make the room dry or settle a medical question. Send the label and we will say which part of that applies to your mattress. No payment to enquire.

Cleaning outcomes are not medical outcomes
“I keep cleaning outcomes separate from medical outcomes. Removing dust does not, by itself, establish asthma relief.”
The founder, Mattress Cleaning SG
The evidence behind that line: a Cochrane review of 55 randomised trials with 3,121 people with asthma found no effect of mite-control measures, mattress encasings included, on asthma outcomes. A separate Cochrane review of mite reduction for eczema could not determine clear implications for practice from very low-quality evidence. This is general information, not medical advice: for allergy, asthma or infection concerns, consult a doctor.
What a mattress clean costs, as advertised
We quote each mattress by size, method and condition after the care label is checked; we do not publish a list yet. These are rates three providers advertise, so you can test any quote, ours included, against the market.
| Provider, method | Single | Queen | King |
|---|---|---|---|
| Helpling, UV-C | S$65 | S$75 | S$80 |
| Helpling, steam | S$80 | S$100 | S$120 |
| Three Butlers, deep | S$100 | S$120 | S$130 |
| Sureclean, wet extraction | from S$125 | from S$165 | from S$195 |
Ask before you book a mite treatment
- Which method is it, and does it put water into the foam?
- Is the price inclusive of GST? IRAS requires GST-registered businesses to quote it in.
- What does the quote claim to remove, and what evidence comes with that claim?
No payment to enquire. A written quote names the method, so you can check it against your warranty terms. Every rate and extra is on the price breakdown page.
The room matters as much as the clean
Meteorological Service Singapore puts the mean annual relative humidity at around 82%, rising above 90% before sunrise and falling to about 60% on a dry afternoon. A mattress spends its life in that air, so the conditions around the bed decide how long a clean holds.
A clean removes the mites and dust it reaches. The next step is the one that lasts: lower the humidity, keep the bedding washed, and use an encasement where allergy is the concern. If the mattress is foam and the label says keep it dry, a wet clean is not the answer, whatever the package is called.
What each method does to the layers is set out on the cleaning methods page; the drying plan for a wet clean is on the deep-cleaning page. What a before-and-after photograph can and cannot prove is on the before-and-after page.
Air
Fans and open windows move air through the room. Air conditioning dries the air it cools. Neither holds a low humidity by itself.
Bedding
Sheets and pillowcases take the closest contact. Wash them at the hottest temperature the care label allows, and dry them fully.
Encasement
A sealed cover traps mites and allergen inside and keeps new ones out. It is a barrier, not a substitute for cleaning.
Questions about dust mites in a mattress
Nine short answers. If yours is about mould, bed bugs or a price, the answers page covers it; if it is about a symptom, a doctor is the right person.
What are dust mites?
Dust mites are eight-legged arachnids, not insects, and they are too small to see without magnification. They feed on shed skin scales and thrive where humidity stays high, which is why a Singapore bedroom suits them.
How do I know if my mattress has dust mites?
You cannot see them by looking. An allergy test shows sensitisation; a dust sample can measure allergen, not live mites. Every home has some, so the useful question is whether the number and the allergen load can be reduced, not whether mites are present.
How do you get rid of dust mites in a mattress?
You reduce them rather than remove them for good: vacuum the surface and seams, wash bedding at the hottest temperature the care label allows, use a sealed encasement if allergy is the concern, and keep humidity down. A professional clean removes what it reaches that day.
Does mattress cleaning kill dust mites?
Some methods kill mites on the surface they treat. That is not the same as removing the allergen, and it does not change the humidity and food supply that let numbers recover. A clean is a reset, not a cure.
Does killing dust mites remove the allergen?
No. The allergen persists in mite bodies and faecal material, so removal matters as much as killing. That is why vacuuming, washing and encasement are judged by what they take out of the bed, not only by what they kill.
Will cleaning my mattress help my asthma or eczema?
We do not promise that. A Cochrane review of 55 randomised trials with 3,121 people with asthma found no effect of mite-control measures, encasings included, on asthma outcomes. A separate review of mite reduction for eczema could not determine clear implications from very low-quality evidence. This is general information, not medical advice; consult a doctor.
What humidity stops dust mites?
Keeping mean daily relative humidity below 50% restricts population growth, even when humidity rises above 50% for two to eight hours a day. At 50%, significant proportions of a population survived for 10 weeks, so the low level has to be held for a long time, not for an afternoon.
Are dust mites a sign of a dirty home?
No. They feed on shed skin and live in fabric and dust, so every home has them. Cleaning reduces the supply and the allergen load; it does not make a home sterile, and a spotless room at 82% humidity can still suit them.
Can I get rid of dust mites permanently?
Not permanently. Control means lowering the food and the humidity they depend on, and removing allergen regularly. A single treatment, however thorough, is followed by the same air and the same shed skin.
