What Is a Verruca?
A verruca is a wart that grows on the sole of your foot — caused by the human papillomavirus (HPV). Unlike warts elsewhere on the body, verrucas get pushed inward by the pressure of walking, which is why they can feel like a small stone underfoot and why they’re often harder to treat than they look.
They’re extremely common, particularly in children and anyone who uses communal changing areas — swimming pools, gyms, leisure centres. They’re not dangerous, but they can be painful, persistent, and — if you’re not careful — spread to other parts of your foot or to other people.
My son swam competitively for years. We became very well acquainted with verrucas. If there were a loyalty card for verruca treatments, I’d have earned a holiday somewhere warm by now. So if you’re a parent staring at your child’s foot wondering what on earth to do next — you’re in exactly the right place.
The frustrating truth is that there’s no single treatment that works for everyone. Some verrucas disappear on their own within months; others stubbornly hang around for years. Most can be dealt with at home — and for the ones that can’t, a podiatrist has several very effective options that most people don’t know about.
How Long Do Verrucas Last?
This is the question every parent asks approximately two weeks into treatment, usually while re-applying plasters at 7am.
The answer varies more than you’d like:
- In children, verrucas often clear up on their own within 2 years without any treatment
- In adults, they tend to be more persistent — sometimes lasting 5–10 years if left untreated
- With active treatment, most respond within 3–6 months
The reason they can last so long is that HPV is clever — it hides from your immune system by living in the outer layers of skin rather than deeper tissue. Treatment works by either destroying the infected tissue directly or triggering an immune response that finally clears the virus.
If yours has been around for more than a few months without changing, it’s unlikely to disappear without active treatment.
Home Treatment Options
1. Salicylic Acid — Start Here
Salicylic acid is the most widely used and best-evidenced home treatment for verrucas. It works by softening and breaking down the hard skin layer by layer, eventually destroying the infected tissue. It requires patience — you’re looking at weeks to months of consistent daily application — but it genuinely works when used properly.
The word “consistent” is doing a lot of heavy lifting in that sentence. This is where most people go wrong — they apply it for a week, see no change, and give up. Give it time.
How to use it:
- Soak the affected area in warm water for 5 minutes to soften the skin
- Gently file away the white, dead surface skin with a pumice stone or emery board (keep a dedicated one — don’t share it)
- Apply the salicylic acid treatment and allow to dry
- Cover with a plaster or the self-adhesive pad provided
- Repeat daily — every day, not most days
My picks:
Bazuka Extra Strength Gel
The one I’d reach for first. The gel formula applies accurately and the higher-strength version is worth using for anything that’s been around a while. Have a look at the applicator design — it makes precise application far easier than older tube-style products, which matters when you’re trying to treat the verruca without irritating the healthy skin around it.
Pharmacy First Salicylic Acid Range
A solid, cheaper alternative with the same active ingredient. Worth considering if you’re planning a longer course — the cost of branded products adds up over weeks of daily use.
2. Freeze Kits — Faster Action at Home
Cryotherapy — freezing the verruca to destroy infected cells — is what podiatrists use clinically, but there are consumer-grade freeze kits available over the counter that work on the same principle, at a lower temperature.
They’re not as powerful as clinical treatment, but they can be effective for smaller or more superficial verrucas, and many people find them quicker to show results than salicylic acid alone.
How they work: The freeze applicator delivers a burst of cold to the verruca, causing the infected cells to die and the skin to blister slightly before peeling away. Most kits recommend 1–2 treatments, repeated after 2 weeks if needed.
My picks:
Wartner Verruca Freeze Spray
The market leader in home freeze kits and consistently well reviewed. The precision applicator is the feature to look at here — it lets you target accurately without catching the surrounding skin, which is particularly useful on a child’s smaller foot or when the verruca is near a toe joint.
Bazuka Sub-Zero Freeze Treatment
A strong alternative with a very similar formulation. Worth having as a backup, or if Wartner is out of stock when you need it.
3. The Duct Tape Method — I Can Speak to This One Personally
You’ve probably come across this. The idea is that covering a verruca with duct tape for extended periods irritates the skin enough to trigger an immune response that clears the virus.
Did we try it? Of course we tried it. The evidence is mixed — some studies show modest benefit, others show no effect beyond placebo. In our case, the verruca was completely unbothered. My son was less bothered by the verruca than by having duct tape on his foot at school, which tells you something.
My honest view: it’s free, it’s harmless, and using it alongside salicylic acid probably doesn’t hurt. But I wouldn’t rely on it alone — especially for anything that’s been there a while.
What Actually Works — A Realistic View
Most people get frustrated with verruca treatment because they expect faster results than are realistic, or they switch products too quickly. Here’s what I’d suggest as a sensible approach:
- Start with salicylic acid — cheap, well-evidenced, no harm if used correctly. Give it 8–12 weeks of consistent daily use before concluding it isn’t working
- Add or switch to a freeze kit if salicylic acid hasn’t made a dent after 6–8 weeks
- Combine both — some people use salicylic acid between freeze treatments with good results
- See a podiatrist if you’ve been treating consistently for 3 months without meaningful progress
It’s worth noting that no home treatment has a 100% success rate — even clinical cryotherapy sometimes takes multiple sessions. Consistency matters far more than which product you choose.
When Home Treatment Isn’t Enough
If three months of consistent home treatment hasn’t shifted it, it’s time to see a podiatrist. This isn’t failure — it’s just the right next step.
I saw enough at the clinic to know that podiatrists deal with stubborn verrucas all the time, and they have treatments that simply aren’t available over the counter. What months of home treatment couldn’t do, a single professional appointment often can.
Clinical Cryotherapy
The same principle as home freeze kits, but far more powerful — liquid nitrogen at -196°C versus home kits at around -57°C. Often resolves verrucas in 1–3 sessions that haven’t responded to months of home treatment.
Needling
The verruca is punctured multiple times under local anaesthetic, pushing HPV cells into deeper tissue and triggering a stronger immune response. Success rates are high — particularly for stubborn or multiple verrucas.
Laser Treatment
Used for resistant cases. Laser targets the blood supply feeding the verruca, destroying it from the inside. More expensive, but effective where other approaches have failed.
Swift Microwave Therapy
One of the newer treatments available in podiatry clinics — microwave energy delivered precisely into the verruca tissue, triggering an immune response. Early results are very promising.
If yours won’t budge, stop spending money on more of the same over-the-counter products and book an appointment instead. Find a podiatrist near you
Ordering Online
If you’d rather skip the pharmacy queue and order at home, these are reliable options:
Click Pharmacy
Good range with fast delivery. Worth checking their current stock on Bazuka and Wartner — they often have deals that work out well if you’re buying for a longer course of treatment.
Pharmacy2U
One of the most established online pharmacies. Handy if you want to order verruca treatment alongside anything else you need in one place.
Stopping Verrucas From Spreading
- Don’t walk barefoot in communal changing areas, poolsides, or gym showers — verruca socks or flip flops are worth the small investment
- Keep feet dry — HPV thrives in warm, moist environments
- Don’t share towels, socks, or shoes with anyone who has a verruca
- Cover it while swimming or in communal areas — a waterproof plaster reduces (though doesn’t eliminate) the risk of passing it on
- Don’t pick at it — you can spread the virus to other parts of your foot, or to your hands
For a competitive swimmer, that last point is easier said than done. We had the conversation many, many times.
FAQ
How do I know if it’s a verruca or a corn?
This catches a lot of people out — they look similar and both hurt. The easiest test: squeeze the area from the sides. Verrucas hurt when squeezed sideways; corns hurt with direct downward pressure. Verrucas also often have tiny black dots in the centre (small blood vessels) and interrupt the natural lines of your skin. If you’re genuinely not sure, a podiatrist can tell you in seconds. See our corn removal guide.
Are verrucas contagious?
Yes, but not dramatically so — you generally need direct contact with the virus, often through broken or wet skin. The highest-risk situations are communal changing areas, shared footwear, and direct contact with an active verruca. Most healthy adults have some natural immunity to the HPV strains that cause verrucas.
Should I treat a verruca that doesn’t hurt?
It depends. If it’s small, not spreading, and not causing any trouble, there’s a reasonable argument for leaving it — particularly in children, where the immune system often clears it naturally given time. If it’s on a pressure-bearing part of the foot, or you notice it growing or multiplying, treat it sooner rather than later.
Can my child go swimming with a verruca?
Yes, but cover it with a waterproof plaster and use verruca socks where the pool allows. Most pools ask that verrucas are covered as a courtesy to other swimmers — check the specific pool’s policy.
How long does professional treatment take?
Clinical cryotherapy is done in sessions 2–3 weeks apart, with most cases clearing in 1–4 sessions. Needling is typically a single treatment with a follow-up check. Your podiatrist will give you a realistic timeframe once they’ve seen it. Find a podiatrist near you
Is it safe to treat a child’s verruca at home?
Salicylic acid is generally considered safe for children over 2 years — always read the product instructions and avoid healthy skin around the verruca. Home freeze kits are usually recommended for adults only, so check the packaging carefully before using on a child. When in doubt, a quick podiatrist appointment is worth the peace of mind.
The Bottom Line
Most verrucas can be treated at home with the right products and — this is the important bit — patience. Salicylic acid is your starting point. Freeze kits are a useful next step for anything stubborn. Give whatever you’re using at least 8–12 weeks before deciding it hasn’t worked.
If three months hasn’t shifted it, stop buying more of the same and see a podiatrist. It’s usually a quick, straightforward appointment — and it often resolves in one or two sessions what months of home treatment couldn’t.
Trust me on that one. I wished I’d done it sooner.
