Ticks

Closely related to the mites, but much larger and reliant on vertebrate blood. They are occasionally brought into the house on domestic animals and can be picked up by humans after walking through long grass in an infested area.

Ticks are implicated in the transmission of Lyme disease and medical advice should be sought if a rash appears at the site of a bite. Remove them with a twist to avoid leaving the mouthparts in the skin.
