Why am I still itching after treatment?
Because that is expected. The itch continues for two to four weeks after successful treatment — it is an immune reaction to dead mites, not evidence that treatment failed. Judge success by whether new spots and burrows are appearing, not by the itch. Repeatedly re-treating causes an irritant dermatitis that itches in its own right, and a great many people get stuck in exactly that loop.
Does everyone really need treating?
Yes — and this is the single most important thing on the page. On a first infestation the itch takes four to six weeks to appear, so contacts who feel completely fine are frequently infested and infectious. Treat every household member and close contact on the same day. Treating only the itchy person is why scabies drags on for months.
Does this mean my house is dirty?
Not at all. Scabies spreads through prolonged skin-to-skin contact — sharing a bed, caring for a child or an older relative, sex — and it is currently common in the UK. It has nothing to do with cleanliness, and washing more neither prevents nor treats it.
Do I need to deep clean the house?
No. Mites survive only about 24 to 36 hours off the body. Wash bedding, towels and recently worn clothes at 60°C on treatment day, and seal anything unwashable in a bag for 72 hours. Vacuum once. That is genuinely all — no fumigation, no professional cleaning, and nobody should be paying for either.
Where exactly do I put the cream?
The whole body from the neck down — not just the itchy parts. Include between every finger and toe, under the nails, the soles, the navel, the genitals and every skin fold. Reapply to your hands after any hand washing. Leave it on eight to twelve hours, then wash off, and repeat the whole thing seven days later. In babies, older adults and anyone immunosuppressed, include the scalp and face too.
Can I go to work or school?
Yes, from the day after the first treatment. There is no need for prolonged exclusion. Avoid prolonged skin-to-skin contact, including sex, until everyone in the household has completed the first application.
I've treated it three times and it's still there.
Then it is almost always one of two things: an untreated contact reinfesting you, or an application problem — missing the hands, not going under the nails, washing hands afterwards without reapplying, or skipping the second dose. Both are fixable. Oral ivermectin is also an option where topical treatment has genuinely failed.
Is scabies an STI?
It can be passed on sexually, since sex involves prolonged skin contact — but it is not exclusively sexually transmitted, and it spreads just as readily between family members and in care settings. If it was acquired sexually, partners need treating, and full STI screening is worth considering alongside.
