How do ticks breathe?

Most nymphal and adult ticks exchange gases through small openings called spiracles that connect to internal tracheal tubes. Larval gas exchange differs because spiracles are not yet developed.

Short answer

Most nymphal and adult ticks exchange gases through small openings called spiracles that connect to internal tracheal tubes. Larval gas exchange differs because spiracles are not yet developed.

At a glance

Tick breathing is passive and does not make smothering remedies a safe or recommended removal method.

Key takeaways

• Spiracles occur near the rear legs in later stages.

• Larvae lack the adult spiracular system.

• Do not try to suffocate an attached tick.

A network of tiny air tubes

Air enters through paired spiracular openings and moves through tracheae to body tissues. Spiracle position and surrounding plates can assist taxonomic identification.

Biology is not a removal instruction

Petroleum jelly, oils and nail products do not provide controlled removal and can delay action. Public-health guidance recommends an appropriate mechanical method.
