The South African bont tick is a hard tick with eight legs and a back painted in patches of different colours. Its legs are dark or reddish with paler joints, like little striped socks. It climbs onto farm animals to drink their blood.

Fun fact: this one is not an insect. It is an arachnid with eight legs, a cousin of the spiders.

Ticks: how to stay safe

  • In Estonia, the castor bean tick and the taiga tick can carry Lyme disease and tick-borne encephalitis.
  • Ticks wait on grass stems, from ankle to knee height. Long trousers tucked into socks and light clothes help you spot them.
  • After playing outside, check your body, your hair and your pets for ticks.
  • Found a tick? A grown-up should take it out quickly with fine tweezers or a tick tool: hold it close to the skin and pull slowly. No oil or alcohol on it. Then wash the spot.
  • There is a vaccine against tick-borne encephalitis, for children too from one year old. Ask your doctor.
  • If in the weeks after a bite you get a fever, feel ill or see a red patch that grows, go to a doctor.
