A tick is a tiny spider-like creature that lives on animals such as sheep or deer.
The main tick feeding season is late spring, early summer and autumn, when they can bite if you are walking through an area where they are present. Ticks can also be carried home by pets and dogs.
Some ticks can pass on the bacteria that causes Lyme Disease.
Senior scientist at Public Health England, Maaike Pietzsch, explains how to avoid being bitten by a tick when out in the natural environment, what to do if you have been bitten and how to remove them. Watch the video.
