What you need to know about ticks in the Netherlands

The number of ticks in the Netherlands increases in the warmer months, meaning that people who go out on trips to the dunes, forests, woods or other green areas, must be extra careful to avoid getting bitten. 

Every year, 1,3 million people are bitten by ticks. Many are also unaware of the dire health issues that can result from a bite. Here's what you need to know about ticks in the Netherlands. 

Symptoms of Lyme disease infection

Lyme disease is caused by bacteria called B. burgdorferi spirochete that gets transmitted from the tick into the blood of humans. Symptoms in early stages often include unrelenting fatigue, recurring fever, headaches and migraines and achy muscles and joints. In many cases, it starts with a red ring or patch on the skin, but this is not always present.

In more severe cases, the illness can completely immobilise a person, causing severe pain, muscle spasms, loss of motor coordination, and even intermittent paralysis, meningitis, and heart problems. It is worth noting that tick bites can also cause other diseases, but the most common one is Lyme. 

Lyme disease statistics

Of the 1,3 million people that are bitten each year, 27.000 people get Lyme disease. Whilst mild forms of the disease can be treated or at least managed with antibiotics prescribed by doctors, about 1.000 to 2.500 people’s symptoms continue after treatment.

Research conducted by the Dutch National Institute for Public Health and Environment to find out why this is did not yield clear findings. There was some correlation between certain higher severity symptoms at the beginning of infection and underlying health issues that predicted chronic symptoms. 

How to avoid getting bitten

NU.nl spoke to two experts on tick bites and how to avoid getting one. "A tick should be removed as soon as possible", said Kees van den Wijngaard, an epidemiologist at the Rijksinstituut voor Volksgezondheid en Milieu (National Institute for Public Health and Environment).

According to Tim Hogenbosch ranger in the Utrecht region, it is important to dress well to prevent tick bites. Ticks can drop from trees but are usually found in low grassland areas, for example, in dunes and forests. "Put your socks on over your pants. It is also a good idea to wear tick-resistant clothing and stay on main paths. It is especially wise to check yourself well, and have others check over parts of your body that you can't see." DEET is also available at pharmacies and may help in keeping ticks at bay.

How to remove a tick

If you get bitten by a tick, it is wise to remove it immediately. There are several tools, but Van Den Wijngaard suggests using pointed tweezers. "Place the tweezers close to the skin and pull the tick straight out. Disinfect the wound afterwards with alcohol." 

Many people think that you have 24 hours to remove a tick, but it's important to remove it as soon as possible. If you have a pet, then it’s best to buy a pipette to kill the ticks on the skin.

Tick distribution in the Netherlands

A project started by the Wageningen University and the Dutch National Institute for Public Health and the Environment (RIVM) launched Tekenradar.nl in 2012. This allows anyone bitten by a tick to report it as a means to participate in research and contribute to tracking the location of ticks in the country.

There are also maps that show the distribution of tick species around Europe available from the European Centre for Disease and Control website. 

Here are the most recent maps showing the distribution of the two main types of ticks in Europe in 2023:
