Need to know how to get rid of dust mites in your home? You've come to the right place.

Dust mites are bad news for allergy sufferers and can be responsible for other common issues such as skin acne. And – these tiny insects are everywhere, including your sofa and your bed. 

Not sure you're dealing with this particular critter? Consult our how to get rid of pests guide to find the one creeping you out.

Lynsey Crombie, a.k.a Queen of Clean explains more: 

'Mattresses are covered in mites. These mites feed on dead skin that we naturally shed in our sleep. This means that you are rolling around and inhaling all kinds of nasty particles which could include fungal spores, bacteria, plasticisers and flame retardants.'

While not a problem for most people, dust mites can wreak havoc with the health of those who are sensitive; if that's you, you'll want to get rid of them asap.

How do you kill dust mites? You can't get rid of them completely, but you can limit their prolific breeding and its effects if you follow these tips.

The best ways to get rid of dust mites

Want to learn how to get rid of dust mites? Let us count the ways. 

During its lifetime, a dust mite can produce up to 200 times its own body weight in faeces and cast skin shells, and its these that trigger allergic reactions in some of us. 

Dust mites breed prolifically, meaning there are millions of them living and feeding on the clothing fabrics, bedding, soft furnishings and carpets in your home – in fact, anywhere that dust gathers.

Martha Stewart explains: 'Dust mites, microscopic insects that live off human and animal skin scales, reside in almost all bedding materials, including pillows, mattresses, and comforters-no matter how clean or immaculate the home.'

So, limiting dust – and other conditions that dust mites love – plus getting into a regular cleaning cycle can limit their numbers, and any allergic reaction to them.

1. Tackle the dust mites in your bedroom (and your mattress)

Regular vacuuming, dusting, airing the room by opening windows and laundering curtains are general steps you can take to kill dust mites. 

More specifically, airing your bedding every day – pushing back the covers instead of making the bed – will reduce the humidity that encourages dust mites. Washing bedding, pillows and duvet once a week on a hot wash will also kill them since they can't survive temperatures of 60ºC; if you  have a tumble dryer, putting the bedding through a hot cycle will finish off any that have survived the wash.

Martha Stewart shares her top tip for cleaning pillows: 

'Set the machine to the gentlest cycle, using warm water; add a small amount of a mild liquid detergent (powder detergent may leave a residue), then fill the tub loosely with your pillows. Repeat the rinse cycle to remove detergent completely.'

If your allergy is very bad, it may be worth investing in mite-proof duvet covers, pillow cases and bed sheets. This hypo-allergenic bedding has a tightly woven fabric that makes it nearly impossible for dust mites to penetrate into the duvets, pillows and mattress; it also prevents your body's moisture and dead skin from doing the same, cutting off their food source.

A good mattress protector will provide a barrier to help prevent dust mites breeding in your mattress, but if you're thinking of replacing your mattress, buying one – and a pillow to match – that's hypo-allergenic will discourage dust mites from living and breeding in your bed. 

Looking for new bedlinen? Bear in mind that wool and silk are both fabrics that are inhospitable to dust mites.

Finally, keep your pets off the bed and, ideally, out of the bedroom – dust mites eat pet dander, too.

2. Getting rid of dust mites in children's rooms

Follow all the tips in the point above, but don't forget to add their soft toys to the list, too. If washable on a hot wash, launder soft toys once a week at 60ºC. 

Dust mites also can't survive below 16ºC, so freezing your child's favourite soft toy (that also seems to make them sneeze) once a week in a plastic bag in the freezer will kill any dust mites. 

Then, simply remove them from the freezer and shake them well outside to remove the dead mites and their faeces.

3. Cleaning up dust mites in living spaces

Dusting by wiping surfaces down with a damp cloth or microfibre cloth will stop you launching dust mites into the air. Dispose of the dust by putting it on a hot wash after cleaning.

A thorough vacuuming once a week – rather than a light vacuuming every few days – with a HEPA filter vacuum cleaner will remove dust mites and their faeces (HEPA stands for High-Efficiency Particulate Air, and these vacuums work by trapping small particles in a fine mesh). See our pick of the best vacuum cleaners for one that can do the job for you.

Steam cleaning carpets, rugs, and furniture can kill dust mites; do this once a week if your allergy is particularly bad, then vacuum the surfaces afterwards to remove them and their faeces. And, when you're cleaning, wearing a mask can stop you inhaling the dust that will aggravate your reactions.

4. Keep heat and humidity down

Dust mites love living in an environment that's similar to what we enjoy – room temperatures between 24°C and 27°C, and humidity at around 70 per cent to 80 per cent suits them just fine, making breeding conditions perfect.

Martha Stewart agrees: 'Dust mites love bedrooms (and beds) because they tend to be especially warm and humid. Bring in a dehumidifier during the summer, or turn on your AC -- cold air is inherently drying'

So, keep heating at no higher than 21°C, which is comfortable for most of us, but not so much for dust mites. Airing rooms to keep humidity levels low will also discourage breeding – if your rooms suffer badly from condensation or it's not practical to air rooms (perhaps your bedroom is on the ground floor), putting a dehumidifier on a timer and setting it to run for an hour or so every morning after you've left for work will do the trick.

5. Use Diatomaceous earth to kill dust mites

This is one of our favourite methods for killing dust mites, even if it sounds a bit out there. Diatomaceous earth is a natural fine powder made from silica rock that you can sprinkle on surfaces where dust mites live (beds, pet beds, furniture, carpets...) to kill them. It works by piercing their exoskeleton as they pass through it, which will kill them instantly. 

Leave the powder for as long as possible – all day while you're out of bed is a good option – then vacuum it up (but ensure you're using a vacuum without a filter so that the powder doesn't clog it up).

This product is safe for us and for our pets, and can also be used to kill fleas and bed bugs.

6. Try a natural remedy

Tea tree oil is a natural antibacterial, antiviral, and anti-fungal oil that is said to kill dust mites, and is definitely worth a try if your allergies are bad. 

Here's how to use it at home:

  • Mix two cups of distilled water with two tablespoons of tea tree oil and two tablespoons of eucalyptus oil in a dark spray bottle (so you can store it away without light spoiling the oils).
  • Spray it liberally onto bedding, furniture and carpets at least once a week – bonus, it will make your home smell nice, too.

7. Swap carpets for hard flooring

Dust mites love to live in carpets because carpets are the perfect environment for trapping dead skin and pet dander. 

If the measures above aren't working for you, it will be worth swapping carpets for hard flooring.

8. Cut down on soft furnishings

Love a throw cushion but constantly sneezing on the sofa or in your bedroom? Cutting down on soft furnishings (the home of dust mites) is another option for allergy sufferers. 

The fabric captures the dust and moisture in the air that dust mites love. Every time you disturb or plump these cushions, the dust will be thrown up into the air and on to other surfaces, and you'll get an allergic reaction.

Don't want to cut down on them? Steam clean them and shake them out in the garden once a week.

9. Keep your pets (and their bedding) clean, too

As we said, dust mites love pet dander, so hot washing their bedding once a week and regularly grooming your pets will keep dust mites at bay. 

If you have a cat or dog that sheds a lot, you'll need to step up the vacuuming, too. If your vacuum's packed it in, have a look at our tried-and-tested guide to the best vacuums for pet hair. This won't just help you – some pets suffer from dust mite allergies, too.

10. Get an air purifier

Fortunately, dust mites are tiny enough to be removed via a HEPA filter in a powerful air purifier. Although it's best to combine all the methods outlined above in combating dust mites, an air purifier will provide much-needed instant relief if you're an allergy sufferer.
