Short answer

Across their many species and life stages, ticks can feed on mammals, birds, reptiles and amphibians. Host preference varies and may change as a tick develops.

At a glance

A tick found on one animal is not automatically specialised for that host. Correct interpretation needs the tick species, life stage and location.

Key takeaways

• Ticks use a wide range of vertebrate hosts.

• Different life stages may prefer different hosts.

• People can be accidental hosts for several species.

Host choice is not universal

Some immature ticks commonly feed on smaller animals while adults seek larger hosts. Other species remain closely associated with one type of animal or the same host environment throughout their development.

Why host records matter

Knowing the animal, place and date can help specialists interpret a specimen. It still does not prove that the tick carried a pathogen or transmitted an infection.
