Eats: BloodScorpions, ticks and friendsForests and woods8 legsNot an insect, but a bug cousin

The deer tick is a tiny tick with dark legs that lives in the woods of eastern North America. It waits on plants and climbs onto animals and people to drink their blood. It has no eyes at all.

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

Its bite can pass on Lyme disease and other illnesses. After playing in the woods or tall grass, ask a grown-up to check you for ticks, and never pull one off yourself.
What does it eat?
It drinks blood at every stage of its life. Babies feed on mice, lizards and birds, and grown-ups love deer.

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.
