Why does a tick need a blood meal?

Ticks are obligate blood-feeding parasites. Blood meals provide the resources needed for survival, development and, in adult females, egg production.

Short answer

Ticks are obligate blood-feeding parasites. Blood meals provide the resources needed for survival, development and, in adult females, egg production.

At a glance

Most ticks feed only a limited number of times during their lives, but an individual meal can last from minutes to days depending on the species and stage.

Key takeaways

• Ticks cannot complete their normal life cycle without feeding.

• Larvae and nymphs usually feed before moulting.

• Adult female feeding supports egg production.

Feeding powers development

After hatching, a larva generally needs a blood meal before moulting into a nymph. The nymph then feeds before becoming an adult. Many adult females require a final meal before producing eggs.

Hosts vary

Depending on species and stage, ticks may feed on mammals, birds, reptiles or amphibians. Finding a tick on one host does not mean that species feeds only on that kind of animal.
