Conducting outdoor activities on overcast or slightly foggy days also reduces shadow detection since contrast with the surroundings is minimized. [21] Ticks can detect the odor of a host. [20] On breezy days remaining downwind from prime ticks habitats will minimize scent detection. [22] Ticks seek hosts only at temperatures above 7 °C (45 °F ...
Ticks are external parasites, living by feeding on the blood of mammals, birds, and sometimes reptiles and amphibians. The timing of the origin of ticks is uncertain, though the oldest known tick fossils are from the Cretaceous period, around 100 million years old. Ticks are widely distributed around the world, especially in warm, humid climates.
Lyme disease, also known as Lyme borreliosis, is a tick-borne disease caused by species of Borrelia bacteria, transmitted by blood-feeding ticks in the genus Ixodes. [4] [9] [10] The most common sign of infection is an expanding red rash, known as erythema migrans (EM), which appears at the site of the tick bite about a week afterwards. [1]
The ticks that transmit Lyme disease are hard ticks. [4] Ticks often have a preferred host, but may still attach to a different host when called for. Their preferred host may change depending on the tick's stage of development (eg larval vs adult) and the host may or may not carry the transmittable pathogen. [3]
Many species of argasid soft ticks are adapted to live in the nest or regular resting sites of their hosts, often waiting for months or even years for the host to return and enable the tick to feed. This nest-dwelling behavior is described as endophilic or nidicolous. [citation needed]
