Ticks attach and feed for a duration that differs on a case-by-case basis. A larval tick will feed for about 3 days, while an adult female could attach for upwards of 10 days. The host may be immune to specific proteins in tick saliva, which makes it harder for the pests to feed. This can result in them being attached for longer, but more often than not it makes the host itch and remove the bug through scratching.
