What is scabies?

Scabies is caused by the scabies mite, a whitish-brown, oval-shaped parasite that digs into the skin's epidermis (top layer), digging track-like 'linear burrows' to lay eggs that develop into adult mites within one to two weeks.

While bedbugs are up to 7mm long when fully grown, scabies mites are a microscopic 0.5mm or less – around the size of the point of a pin – and invisible to the naked eye.

Although the average infected person will have just 10-15 scabies mites on them, this is enough to lead to unpleasant symptoms, including a rash.

While cases have fallen from the peak seen in January 2024, the Royal College of General Practitioners told Which? they remain above the five-year average, with two cases per 100,000 of the population (three per 100,000 in the north of England) being reported.

What does scabies rash look like?

Classic (typical) scabies 

You usually see symptoms around 4-6 weeks after infestation, when the body starts to have an allergic reaction to mite proteins and droppings. Telltale signs include: 

• Severe itching that's often worse at night. This is because the skin is warmer, making the mites more active.
• A rash of tiny raised linear burrows. These tracks are from the female laying eggs under the skin and appear as fine, dark or silvery lines that can be up to 1cm long.
• Blister or bumps (papules). These are typically on the fingers (especially in the webs), wrists, arms, armpits, legs, groin and in the belt area.

Crusted (Norwegian) scabies

When a case of classic scabies infestation ramps up and the number of mites reaches thousands or even millions, it's classified as crusted scabies.

Vast numbers of mites inhabit crusty scabs created by their activity under the skin and when these are shed the mites fall with them, each seeking a new host.

This extremely contagious form of scabies is mainly seen in people with suppressed immune systems or other conditions.

How do you catch scabies?

Anyone can catch scabies. The scabies parasite is transmitted through direct, prolonged skin contact with someone who is already infected – someone you sleep in the same bed with, for example.

Scabies can also be commonly spread in places like nurseries, playgroups or schools where children often play in close contact, as well as residential homes.

It's also more prevalent in the winter months, when people huddle together and cooler temperatures enable mites to survive for longer away from their host.

What is the best treatment for scabies?

Treatment for scabies is topical permethrin cream or malathion lotion from your pharmacy or on prescription from your GP and in the case of crusted scabies you'll probably be prescribed oral medication too.

Everyone in the household should be treated at the same time (even those without symptoms) to prevent them passing on the infection. Treatment should be repeated to kill newly hatched mites and stop the lifecycle.

Continue with treatment as directed and don't stop without guidance, even if your symptoms appear to be improving.

Although scabies clears up quickly with the right treatment, it's common for itchiness to worsen for one to two weeks after treatment begins. You may get some relief from taking antihistamines (like those commonly used for conditions such as hayfever).

Is there a shortage of scabies medication this summer?

In January, the British Association of Dermatologists said a surge in demand for treatments across Europe, supply chain issues and increases in the cost of raw materials were contributing to a shortage of permethrin cream and malathion lotion.

When Which? spoke to the Royal Pharmaceutical Society at the end of June, a spokesperson told us that currently there are no reported shortages of treatment for scabies, although if you do run across difficulties getting hold of it you should first consult with your healthcare provider or pharmacist for guidance on alternative treatments or sourcing options.

There is no evidence to suggest summer is worse for the spread of scabies - in fact, public health data comparing five-year average statistics appears to show a lull in cases in the spring and summer .

However, heat intensifies itching for many people with skin conditions where itch is a symptom, including scabies.

Our research into medicine shortages found a quarter of Which? members who collected prescription medicine had to wait longer than usual, due to low stock at their pharmacy. Follow our guidance on being proactive about managing your medication to help you take charge of your health.

Cleaning your home when you've got scabies

Scabies mites can only survive for two or three days away from human skin, which is why infestation most commonly occurs from skin-to-skin contact. 

Although it's rare, there are other situations in which you can pick up scabies without being in direct contact with another human, including exposure to scabs shed by someone with crusted scabies or picking up a mite from an item such as bedding.

Here are some potential problem areas in the home plus how to keep them clean.

Bedding, towels and clothes

Wash and dry bedding and clothing that's been in contact with an infested person to kill both mites and eggs, but make sure the machine cycle is 50°C or above.

Natalie Bungay of the British Pest Control Association, says: 'Using 30 degree cycles or lower may be a popular choice but scabies eggs are hardy and might survive this, even if the mites don't. So the hotter the washing cycle, the better.'

• Dry on a hot dryer cycle or dry in the sunshine. The UV light helps to kill parasites, even if it's not the height of summer.
• Dry clean items that can't go in the machine. These could include overcoats, duvets or other delicate or bulky items.
• Put items in a sealed bag for a week. This is for items that can't be washed or dry-cleaned – the bag should be air-tight and not made from loose-weave fabric that these pinprick-sized mites could escape through.

Mattresses

While bedbugs can survive on mattresses for up to four months, scabies mites can only live on them for up to three days.

This means so you should be able to get rid of them rather than having to go to the bother and expense of throwing your mattress away.

Vacuum every side and seam of each mattress that's being used in your home, put all bedding on a hot wash immediately and use a plastic mattress cover – if any mites remain, this physical barrier will prevent them from reaching you before they quickly perish.

Natalie says: 'You can also steam clean your mattress to kill scabies mites long as it's safe to do it and the label advises you that you can.'

Sofa and armchairs

Cleaning your lounge furniture may be especially important if you're the sort of family that piles on the same sofa to watch TV as scabies mites revel in any opportunity to transfer from one host to the next – here's how to clean up.

• Vacuum the entire sofa and armchairs. Do every side (even the narrow bits you don't normally see) and use an attachment to get into the seams.
• Clean any part that's removable. Whether it's scatter cushions, sofa cushions, slip covers or throws and blankets, these need to be cleaned, too – washable parts should go in the washing machine and put cushions in sealed bags for a week. 
• Dispose of your vacuum cleaner bag carefully. Throw disposable bags immediately into the outside bin and do the same with the contents of a bagless vacuum cleaner before replacing the filter and washing any washable parts of the vacuum cleaner with hot water.

Do you need to clean anywhere else?

Natalie Bungay says: 'Scabies mites don't like hard finishes so you shouldn't need to deep clean or disinfect surfaces such as countertops, bath tubs or sinks.'

However, there's an outside chance an opportunistic mite could latch on to a host from a hard surface, such as a child playing on a wooden floor.

If you've been shaking out or rearranging throws and blankets during a known infestation or when someone has highly infectious crusted scabies, you could vacuum the floor of that room as a precaution.

What else do you need to know about scabies?

You don't get scabies because you're not clean

Scabies isn't to do with untidiness or poor hygiene.

Dr Tess McPherson, president of the British Society for Paediatric and Adolescent Dermatology, says: 'It is important to state you do not get scabies because you are unhygienic, and we must reduce any stigma associated with having scabies so that people do seek treatments when needed.'

Let your child's school or nursery know if they have scabies and keep siblings off school until treatment has started to prevent passing it on to others – you or your child can go back to work or school 24 hours after the first treatment.

You can't get scabies off your pet – or give it to them

Natalie says: 'Mange in dogs is a form of scabies but although the mites involved can get on to you, they can't breed and complete their life cycle. So they may irritate your skin but then they'll just die.'

Equally, human scabies mites could jump ship from you onto your pet. But they, too, won't be able to breed unless they can quickly get back to human skin.

As a precaution, especially if a family member has crusted scabies and you think scabs may have dropped into your pet's bed or basket, wash their bedding on a hot wash as per the guidance for human bedding above and speak to your vet for further guidance.

Follow the people to find the mites

Scabies mites are human-centric pests, so do some basic detective work to find out whereabouts in your home you might need to clean in the wake of an infestation.

Look for places in your home where you and others like to hang out – such as soft furnishings – and that's where scabies mites are most likely to be found.

If you've got a child who likes to sit in a nook or cranny to read a book, make sure you clean that space if they've got scabies.
