What does engorged mean?

An engorged tick has expanded while taking a blood meal. Its body may become much larger and less similar to an unfed identification image.

Short answer

An engorged tick has expanded while taking a blood meal. Its body may become much larger and less similar to an unfed identification image.

At a glance

Engorgement describes feeding condition, not whether the tick carries a pathogen.

Key takeaways

• Body shape changes during feeding.

• An engorged tick can be harder to identify visually.

• Remove an attached tick promptly with an appropriate method.

A dramatic but normal feeding change

The flexible rear body expands as a hard tick feeds. Colour, markings and proportions can become obscured, which is why identification may require mouthparts, legs or other structures.

Do not read infection from size

A large tick is not automatically infected, and a small tick is not automatically safe. Disease risk requires regional and clinical context.
