How do I avoid ticks, and how do I remove one safely?

Where ticks are, how to keep them off you, the correct removal technique with a proper tool, and the symptoms that mean you need a GP rather than a plaster.

Short answer

Cover your legs, tuck trousers into socks, stay on paths and out of bracken and long grass, and check yourself, children and dogs thoroughly at the end of every walk. Remove a tick with a tick removal tool or fine-tipped tweezers, gripping as close to the skin as possible and pulling steadily straight out without squeezing the body. Note the date, and see a doctor if a spreading rash or flu-like symptoms appear.

Ticks are established across much of the UK and are not confined to any one region, though they are most numerous in areas with deer, sheep and dense ground vegetation — the Scottish Highlands, Exmoor, the New Forest, Thetford Forest, the South Downs and the Lake District among many others. Most bites cause nothing. A minority transmit Lyme disease, which is straightforward to treat when caught early and much harder later, which is why prompt removal and knowing the symptoms matter.

Safety

Ticks in the UK can carry Lyme disease. Removing a tick promptly and correctly substantially reduces the risk of transmission, and squeezing, twisting off the body, burning or smothering a tick makes it worse by causing it to regurgitate into the bite. See a doctor if you develop an expanding circular rash — which may or may not be the classic bullseye — or a flu-like illness in the weeks after a bite, and tell them you were bitten by a tick.

What you'll need

A tick removal tool or fine-tipped tweezers
Long trousers and socks
Insect repellent containing DEET or picaridin
A mirror or a second person for checking

Removing an attached tick correctly, and what not to do

Step by step

Know where they are.Ticks wait on the tips of vegetation with their front legs out, at roughly knee height, and grab onto what brushes past. Bracken, long grass, heather, woodland edge and deer paths are the places to expect them. They are most active from spring to autumn, and mild winters extend the season.
Cover up and tuck in.Long trousers tucked into socks, long sleeves, and light-coloured clothing so you can see a tick crawling on you. Ticks climb upwards, so stopping them at the ankle catches most of them.
Use repellent on skin and clothing.Repellents containing DEET or picaridin work on skin. Permethrin treatment of clothing is highly effective and is applied to the fabric, not the skin — follow the product instructions exactly.
Stay on the path.The single most effective measure. Walking through bracken and long vegetation is what collects them; walking on a mown or worn path collects very few.
Check thoroughly, the same day.Ticks look for warm, thin skin: behind the knees, groin, waistband, armpits, navel, behind the ears, along the hairline and on the scalp. Nymphs are the size of a poppy seed and are the stage that most often transmits infection, so this needs a proper look rather than a glance. Check children and dogs too.
Remove it with a proper tool, straight away.A tick removal tool slides under the body and lifts or twists the tick out whole; fine-tipped tweezers grip the tick as close to the skin as possible, at the head end rather than the body. Pull steadily and firmly straight out. Do not jerk, do not twist with tweezers, and do not squeeze the body.
Clean the bite and record the date.Wash with soap and water or antiseptic. Write down the date and where on the body it was, and take a photograph. If symptoms appear weeks later, that record is exactly what a doctor needs.
Deal with a broken mouthpart calmly.If part of the tick is left behind, it is not a disease risk in itself; treat it like a splinter. Clean it and let the skin expel it, or see a nurse if it is inflamed.
Watch for symptoms for several weeks.Erythema migrans, the expanding rash, typically appears from three days to three months after the bite and often around one to four weeks. It spreads outwards, is usually not itchy or painful, and only sometimes has the classic bullseye appearance. Flu-like symptoms, fever, headache, joint pain and fatigue also matter. Any of these means a GP appointment, and say you were bitten by a tick.
Do not wait for a test to seek treatment.Lyme disease is diagnosed clinically where the characteristic rash is present, and treatment with antibiotics is started without waiting for blood tests, which can be negative early on. Early treatment is highly effective, which is why not delaying matters.

Tips

Carry the tick tool with you rather than leaving it at home. Removing a tick within hours is what reduces the risk, and two of them cost very little.
A tick that has fed for a long time is engorged and grey-brown; one that has just attached is flat and dark. Either way, remove it now.
Showering after a walk helps you find them and washes off unattached ones.
Tumble drying clothes on high heat kills ticks in the fabric; washing alone does not reliably.
Not every tick carries Lyme disease and most bites cause no illness at all. The point is not to worry but to check, remove promptly and know the symptoms.

Common mistakes

Burning a tick off, or smothering it with petroleum jelly or alcohol — It irritates the tick into regurgitating into the wound, which is exactly the mechanism that transmits infection. Remove it mechanically and immediately.
Squeezing the tick's body with fingers or blunt tweezers — Same problem — squeezing forces gut contents into the bite. Grip at the head, close to the skin, with a proper tool.
Assuming no rash means no risk — A substantial minority of Lyme cases never show the classic rash. Flu-like illness in the weeks after a bite is enough reason to see a doctor and mention the bite.

If it doesn't work

A small dark speck that will not brush off

Cause: An attached nymph tick — Fix: Remove with a tick tool or fine tweezers. They are genuinely tiny and easy to mistake for a freckle or a piece of dirt.

A red mark around the bite immediately after removal

Cause: Local irritation from the bite itself — Fix: Normal. It is a small red spot that fades over days. What matters is a rash that expands over days to weeks.

An expanding circular rash

Cause: Erythema migrans — the characteristic early sign of Lyme disease — Fix: See a GP promptly. Treatment is a course of antibiotics and it is highly effective at this stage.

Ticks repeatedly on the dog

Cause: Walking regularly in tick habitat — Fix: Speak to a vet about preventative treatment, and check the dog after every walk — behind the ears, in the armpits, between the toes.

Questions people ask

How long does a tick have to be attached to transmit Lyme disease?

Risk increases with the length of attachment, and prompt removal substantially reduces it. That is the whole reason for checking the same day rather than the next morning.

Should I get the tick tested?

Testing the tick is not routinely available or recommended in the UK and a negative result would not rule out infection. What matters is prompt removal and watching for symptoms.

Are ticks only in Scotland?

No. They are widespread across the UK, including southern England, and Lyme disease is diagnosed in every region. Habitat matters far more than which part of the country you are in.
