Ticks in Spain: Species, Lyme Disease Risk & Prevention Guide

Spain is home to several medically significant tick species, including Hyalomma marginatum (which transmits Crimean-Congo haemorrhagic fever in central and southern Spain), Ixodes ricinus (which transmits Lyme disease, mainly in the humid north), and Dermacentor species. Tick season runs from March to October, with peak activity in April through June. The most effective prevention is wearing long clothing treated with permethrin, using DEET-based repellents on exposed skin, and performing thorough tick checks after any outdoor activity in rural areas. Pets should be on year-round veterinary tick prevention.

This guide covers every tick species you’ll encounter in Spain, the diseases they carry, where and when you’re most at risk, and exactly how to protect yourself, your family, and your pets.

What Tick Species Are Found in Spain?

Spain’s varied climate — from the wet, temperate north to the arid Mediterranean south — supports a diverse range of tick species. Three genera cause the vast majority of problems for residents and visitors.

Hyalomma marginatum (Mediterranean Hyalomma Tick)

This is the tick that makes Spain’s tick risk profile genuinely different from Northern Europe. Hyalomma marginatum is a large, hard-bodied tick found throughout central and southern Spain, the Mediterranean coast, and the Balearic Islands. It’s the primary vector for Crimean-Congo haemorrhagic fever (CCHF) in Spain.

Key characteristics:

• Large and visible: Adult Hyalomma ticks are 5-8mm unfed (up to 20mm when engorged) — significantly larger than other European tick species. They have distinctive striped legs.
• Active hunters: Unlike most ticks that wait passively on vegetation (questing), Hyalomma ticks actively detect hosts from several metres away using vibration and CO2 sensing, then run towards them. They are fast-moving and surprisingly aggressive.
• Heat-loving: Most active during the hottest months (June-September), precisely when other European tick species are less active. This is the opposite of what many expats expect.
• Hosts: Adults feed primarily on large mammals — cattle, horses, deer, wild boar, and humans. Larvae and nymphs feed on birds, hares, and hedgehogs.

Distribution in Spain: Common across Extremadura, Castilla-La Mancha, Andalucia, Murcia, the Comunidad Valenciana, and parts of Aragon and Catalonia. Particularly associated with dehesa landscapes (open oak woodland with livestock) and rural areas with wild ungulates.

Ixodes ricinus (Castor Bean Tick / Common Sheep Tick)

Ixodes ricinus is the tick most Northern Europeans recognise — it’s the primary vector for Lyme disease (borreliosis) in Europe, and it’s well established in northern and central Spain.

Key characteristics:

• Small: Adults are 3-4mm unfed, nymphs just 1-2mm — the nymphs are the stage most commonly responsible for transmitting Lyme disease to humans because they’re so small that people don’t notice them.
• Passive questing: Climbs vegetation (grass, low shrubs, bracken) and waits with forelegs extended to grab passing hosts. Doesn’t actively hunt.
• Moisture-dependent: Requires humid microenvironments and is most common in deciduous and mixed forests, hedgerows, and areas with thick undergrowth and leaf litter.
• Spring-active: Peak activity from March to June, with a secondary peak in September-November.

Distribution in Spain: Abundant in Galicia, Asturias, Cantabria, the Basque Country, Navarra, La Rioja, and humid areas of Catalonia, Aragon (Pyrenees), and the Sistema Central mountain ranges. Rare or absent in the dry lowlands of Andalucia, Murcia, and the Levante.

Dermacentor marginatus (Ornate Sheep Tick)

Dermacentor marginatus is widespread across Spain and is the vector for Mediterranean spotted fever (also called boutonneuse fever), caused by Rickettsia conorii.

Key characteristics:

• Medium-sized: 4-5mm unfed, with a distinctively patterned (ornate) dorsal shield.
• Cold-tolerant: Unlike Hyalomma, Dermacentor ticks are active during cooler months — autumn and winter into early spring. This extends Spain’s effective tick season to nearly year-round.
• Habitat: Open grasslands, scrubland, and agricultural margins. Common in periurban areas where livestock and wildlife overlap with human activity.

Distribution in Spain: Found across all regions, from the Pyrenees to Andalucia. Particularly common in pastoral areas with sheep and goats.

Other Notable Species

• Rhipicephalus sanguineus (Brown Dog Tick): Primarily a parasite of dogs but will bite humans in heavy infestations. Can complete its entire lifecycle indoors, making it the only tick species that infests houses in Spain. Transmits canine ehrlichiosis and babesiosis. Common throughout Spain, especially in kennels and properties with multiple dogs.
• Ixodes frontalis: A bird-associated tick found in gardens and urban parks. Occasionally bites humans but not considered a significant disease vector.

Where Will You Find Ticks in Spain?

Understanding tick habitat helps you assess your personal risk level and take appropriate precautions.

High-risk environments:

• Dehesa landscapes (Extremadura, Salamanca, Andalucia): Open oak woodland with livestock — ideal habitat for Hyalomma and Dermacentor ticks. Walking through these areas in summer without precautions is high-risk.
• Northern forests (Galicia, Asturias, Basque Country, Pyrenees): Dense deciduous and mixed forest with undergrowth — prime Ixodes ricinus territory and the highest Lyme disease risk in Spain.
• Hunting reserves and rural estates (cotos de caza): Wild boar and deer populations support large tick populations. If you hunt or walk on these estates, tick exposure is virtually guaranteed during season.
• Mountain trails (Sistema Central, Sierra Nevada, Picos de Europa, Pyrenees): Ticks are common along hiking trails where vegetation brushes against walkers. Trail edges and resting spots in grass are higher risk than the trail centre.

Moderate-risk environments:

• Periurban green spaces: Parks, greenways, and waste ground on the edges of towns where dogs, foxes, and rabbits sustain tick populations.
• Golf courses and urbanisation edges: Irrigated areas bordering rural land attract wildlife and, by extension, ticks.
• Gardens backing onto campo: If your Spanish property borders rural land, ticks can enter your garden on wildlife — hedgehogs, foxes, and feral cats are common tick carriers.

Lower-risk environments:

• Urban centres: Ticks are uncommon in built-up urban areas, though the brown dog tick can be found where stray dogs are present.
• Beaches and coastal dunes: Generally low tick risk, though Hyalomma can be present near coastal scrubland.

When Is Tick Season in Spain?

Spain’s tick season is longer and more complex than in Northern Europe because different species are active at different times of year.

March-June: Peak activity for Ixodes ricinus in northern Spain. This is when Lyme disease transmission risk is highest. Nymphs — the most dangerous stage for human infection — are abundant in forests and undergrowth.

June-September: Peak activity for Hyalomma marginatum in central and southern Spain. This is when Crimean-Congo haemorrhagic fever risk is highest. These large ticks are active during the hottest part of the year, making summer hiking in rural Extremadura and Castilla-La Mancha a higher-risk activity than many realise.

September-November: Secondary peak for Ixodes ricinus and beginning of Dermacentor activity. Autumn hiking in northern Spain still carries tick risk.

November-March: Dermacentor marginatus remains active through winter in milder parts of Spain. While overall tick risk drops significantly, it never reaches zero in southern regions.

The practical takeaway: In Spain, there is no month when you can completely ignore ticks if you spend time outdoors in rural areas. The traditional Northern European advice of “check for ticks from April to September” needs extending in both directions here.

Lyme Disease Risk in Spain

Lyme disease, caused by the spirochete bacteria Borrelia burgdorferi (and related species), is transmitted by Ixodes ricinus ticks. Spain’s Lyme risk is real but geographically concentrated.

Where the risk is highest:

• Galicia, Asturias, Cantabria, and the Basque Country have the highest incidence, with their humid Atlantic climate providing ideal conditions for Ixodes ricinus.
• The Pyrenees (Navarra, Aragon, Catalonia) are also significant Lyme areas.
• Wooded areas of the Sistema Central (north of Madrid) harbour Ixodes populations at altitude.

What the data shows: Spain reports an estimated 300-500 confirmed Lyme disease cases annually, though underdiagnosis is widely suspected, particularly among expats who may not associate their symptoms with a tick bite received weeks earlier. Incidence has been trending upward over the past decade, likely due to a combination of increased awareness, improved diagnostics, and expanding tick habitats linked to climate change.

Symptoms to know:

• Erythema migrans (EM): A spreading circular rash, often with a central clearing (“bull’s eye”), appearing 3-30 days after a bite. Present in 60-80% of Lyme cases. This is the most reliable early sign.
• Early disseminated: Fatigue, headache, muscle and joint pain, fever. Can develop weeks after the bite.
• Late Lyme disease: Joint inflammation (particularly knees), neurological symptoms (facial palsy, meningitis, nerve pain), and cardiac involvement. Develops months after untreated infection.

Important: Lyme disease is treatable with antibiotics, especially when caught early. If you develop an expanding rash or flu-like symptoms within a month of a tick bite, see your doctor promptly and specifically request a Lyme evaluation.

Crimean-Congo Haemorrhagic Fever (CCHF) in Spain

CCHF is the more serious — though far rarer — tick-borne disease risk in Spain, and it’s one that most expats have never heard of.

The vector: Hyalomma marginatum, which is widespread across central and southern Spain.

Spain’s history with CCHF: Spain confirmed its first autochthonous CCHF cases in 2016 in Avila province (Castilla y Leon), when a man died after being bitten by a Hyalomma tick while walking in the countryside. A nurse who treated him also contracted the virus and recovered. Additional cases have been detected sporadically since, and surveillance has revealed that the CCHF virus is circulating in Hyalomma tick populations across a wider area than initially expected — including parts of Extremadura, Castilla-La Mancha, and Andalucia.

Risk level: The overall risk to any individual is very low. CCHF remains rare in Spain and most tick bites — even from Hyalomma — do not transmit the virus. However, CCHF has a case fatality rate of 10-40%, making awareness important.

Symptoms: Sudden onset of fever, muscle pain, dizziness, neck pain and stiffness, headache, sore eyes, and sensitivity to light. This progresses to nausea, vomiting, diarrhoea, and in severe cases, haemorrhagic symptoms (bruising, nosebleeds, bleeding gums). Symptoms appear 1-13 days after a tick bite.

What to do: If you are bitten by a large tick (likely Hyalomma) in central or southern Spain and develop fever within two weeks, seek medical attention immediately and inform the doctor about the tick bite. Mention CCHF specifically — many Spanish doctors outside endemic zones may not immediately consider it.

How to Remove a Tick Safely

Proper tick removal is critical. Incorrect removal increases the risk of pathogen transmission by squeezing infected material into the wound or leaving mouthparts embedded in the skin.

What you need: Fine-pointed tweezers (not blunt household tweezers) or a purpose-made tick removal tool. Tick removal kits are available at Spanish pharmacies and on Amazon.es for under 10 euros.

Step-by-step removal:

1. Grasp the tick as close to the skin surface as possible with fine-pointed tweezers. Get under the tick’s body, right where the mouthparts enter the skin.
2. Pull upward with steady, even pressure. Do not twist, jerk, or wiggle — a slow, firm pull straight up. The tick should release within 10-30 seconds.
3. Do not squeeze the tick’s body. Compression can force infected saliva or gut contents into the bite wound.
4. Inspect the bite site. If small mouthparts remain in the skin, they will usually work themselves out naturally. Do not dig around with needles or tweezers — this causes more damage.
5. Clean the bite area thoroughly with antiseptic (povidone-iodine or chlorhexidine, both available at any Spanish pharmacy as Betadine or Cristalmina).
6. Save the tick in a sealed container or zip-lock bag. If you develop symptoms later, the tick can be identified and tested. Photograph it as well.
7. Note the date and body location of the bite. Mark your calendar to watch for symptoms over the following 30 days.

What NOT to do:

• Do not apply petroleum jelly, nail polish, or oil to suffocate the tick. This takes too long and may cause the tick to regurgitate into the wound.
• Do not use a hot match or cigarette to burn the tick off. Same risk of regurgitation, plus burn injury.
• Do not crush the tick with your fingers — use tissue paper and dispose of it, or flush it down the toilet.

Prevention for Hikers and Outdoor Enthusiasts

If you hike, trail run, mountain bike, hunt, or spend time in rural Spain, tick prevention should be as routine as sun protection.

Clothing:

• Wear long trousers tucked into socks when walking through vegetation — yes, even in Spanish summer heat. Light-coloured clothing makes ticks easier to spot.
• Treat hiking clothes and boots with permethrin spray (available on Amazon.es). Permethrin-treated clothing kills ticks on contact and remains effective through multiple washes.
• Wear a hat when walking under low branches — ticks don’t jump or fly, but they can drop from vegetation.

Repellents:

• Apply DEET (20-50%) or icaridin/picaridin (20%) to exposed skin. The same repellents that work for mosquitoes are effective against ticks.
• Reapply according to product instructions, especially after sweating.

Behaviour:

• Stay on the centre of trails when possible — brushing against trailside vegetation is how most ticks are acquired.
• Avoid sitting directly on grass, log piles, or stone walls in tick habitat. Use a groundsheet or blanket.
• Perform a full-body tick check within two hours of returning from the field. Check carefully: scalp, hairline, ears, armpits, waistband, groin, behind the knees, and between the toes. Use a mirror or ask a partner to check your back.
• Shower within two hours of outdoor activity — this helps wash off unattached ticks and provides an opportunity for a thorough check.

Prevention for Pet Owners

Dogs are highly susceptible to tick-borne diseases in Spain, and they also bring ticks into your home and garden. Cats are less commonly affected but should also be protected.

For dogs:

• Use veterinary tick prevention year-round in Spain. The milder winters mean ticks can be active in any month. Oral preventatives (Bravecto, NexGard, Simparica Trio), spot-on treatments (Frontline Combo, Advantix), and long-acting collars (Seresto) are all available from Spanish veterinarians and online pet pharmacies.
• Advantix deserves special mention for Spain because it repels as well as kills ticks (and sandflies, which transmit leishmaniasis). However, Advantix is toxic to cats — do not use it in households where cats and dogs are in close contact.
• Check your dog after every rural walk, focusing on the head, ears, neck, armpits, and between the paw pads.
• Brown dog tick infestations can become established in homes with dogs, particularly in kennels, cracks in walls, and under furniture. If you find ticks on your dog that you did not acquire outdoors, inspect your property for an indoor infestation — this requires professional treatment.

For cats:

• Use a cat-specific tick treatment (Frontline Combo for cats, Broadline). Never apply dog tick products to cats — permethrin-based products are lethal to cats.

Garden management:

• Keep grass short, especially around the perimeter of your property.
• Remove leaf litter and brush piles where ticks harbour.
• Create a barrier of gravel or wood chips between wooded areas and your lawn — ticks are less likely to cross dry, open surfaces.
• Discourage wildlife passage through your garden where possible — hedgehogs, foxes, and feral cats all carry ticks.

When to See a Doctor

Seek medical attention if any of the following occur after a tick bite:

• An expanding red rash at or near the bite site, especially one with central clearing (bull’s eye pattern). This is erythema migrans and indicates probable Lyme disease. Treatment with antibiotics is straightforward if started early.
• Fever, headache, muscle pain, or fatigue developing within 1-30 days of a tick bite. Mention the tick bite explicitly to your doctor.
• The bite site becomes increasingly red, swollen, hot, or painful — this may indicate secondary bacterial infection rather than tick-borne disease, but still requires medical evaluation.
• You were bitten by a large tick in central/southern Spain (likely Hyalomma) and develop any symptoms within two weeks. Mention Crimean-Congo haemorrhagic fever to the doctor.

Navigating Spanish healthcare for tick bites: Visit your Centro de Salud (local health centre) for a non-emergency evaluation, or Urgencias (A&E) if you develop high fever or haemorrhagic symptoms. The Spanish word for tick is garrapata and for tick bite is picadura de garrapata. Lyme disease is referred to as enfermedad de Lyme or borreliosis.

Prophylactic antibiotics: Unlike in the US, routine prophylactic antibiotic treatment after every tick bite is not standard practice in Spain. Spanish guidelines recommend watchful waiting and treatment if symptoms develop. If you removed the tick within 24-36 hours, the risk of Lyme transmission is very low — the bacteria typically require 36-48 hours of tick attachment to be transmitted.

Professional Tick Control for Properties

If your property is in a rural area with persistent tick problems — particularly if you have dogs, horses, or livestock — professional pest control can reduce tick populations on your land.

What professionals offer:

• Perimeter barrier spraying: Similar to mosquito barrier treatments, residual acaricides are applied to garden borders, vegetation, and shaded resting areas where ticks harbour. Treatments typically last 4-6 weeks.
• Targeted treatment of kennels and dog runs: Essential for brown dog tick infestations, which can become established indoors.
• Environmental modification advice: Professional assessment of your property’s tick risk and recommendations for habitat management.

Cost in Spain: Expect to pay 100-200 euros per treatment for a standard garden, with seasonal packages available. See our guide to pest control companies in Spain for verified providers.

DIY garden treatment: For smaller properties, products containing deltamethrin or cypermethrin are available at Spanish agricultural suppliers (cooperativas agrarias) for perimeter spraying. Follow label instructions carefully and keep children and pets off treated areas until dry.
