How does a tick cut into skin?

A tick uses paired chelicerae to cut into the skin and positions its barbed hypostome in the feeding lesion while saliva helps maintain attachment and blood feeding.

Short answer

A tick uses paired chelicerae to cut into the skin and positions its barbed hypostome in the feeding lesion while saliva helps maintain attachment and blood feeding.

At a glance

Ticks do not drill with their whole head; several specialised mouth structures work together at the attachment site.

Key takeaways

• Chelicerae create the feeding lesion.

• The hypostome helps anchor the tick.

• Saliva has several feeding functions.

A controlled sequence

After selecting a site, the tick alternates movements of its cutting structures and inserts the central hypostome. Some species also produce a cement-like attachment material.

Why prompt removal uses skin-level control

Gripping near the attachment point helps avoid squeezing the expandable body. Removal guidance should come from current public-health or veterinary authorities.
