How Do Ticks Find You?
Ticks don't chase you down — they wait. This behaviour is called questing. A tick climbs onto a blade of grass or a leaf, stretches out its front legs, and simply waits for something to walk past.
Haller's Organ
Ticks don't have eyes. Instead, they "feel" the world using a special sensor on their front legs called Haller's organ. This tiny organ can detect:
- Carbon dioxide (the gas you breathe out)
- Body heat
- Vibrations
So even though a tick can't see you coming, it knows you're there — and it will move toward you.
Each leg ends in a small claw. All it takes is one brush against it, and the tick grabs on. From there, it starts climbing upward, looking for a good spot to feed. Its spiny hairs and claws help it grip onto grass, leaves, and branches while it waits.
This is also why ticks are so hard to brush off once they've latched on — that same Haller's organ, made up of a tiny pit filled with sensitive hairs, keeps helping the tick stay locked onto its target.
The Head of a Tick
A tick's mouth is built for one job: staying attached while it feeds. It has three main parts:
- Two palps — these feel around for the best spot to bite but don't actually pierce the skin
- Two chelicerae — these are like tiny hooks that cut into the skin
- One hypostome — a barbed, needle-like tube that goes in and anchors the tick in place
The hypostome is covered in curved barbs — up to 48 of them — arranged in rows. These barbs bury about half a millimetre into your skin.
Built to Stay a While
Here's how it works: the palps find the perfect spot, then move out of the way. The chelicerae cut a small opening and pull the hypostome deeper into the skin, bit by bit.
Because the hypostome's barbs curve backward, once it's in, it's very hard to pull out cleanly — which is exactly why removing a tick the wrong way can leave part of it behind, or damage your skin.
One common myth worth clearing up: it's not the tick's whole head that gets stuck in you, only this one barbed part, the hypostome.
Why You Don't Feel a Tick Bite
Before a tick starts feeding, it injects saliva into your skin. This saliva is doing a lot of work behind the scenes — it actually switches off your body's usual warning signs, which is why bites often go completely unnoticed.
The saliva contains:
- Numbing chemicals — so you don't feel the bite
- Anticoagulants — which stop your blood from clotting, so it keeps flowing
- Vasodilators — which widen your blood vessels to bring more blood to the area
Many tick species overseas also produce a natural "cement" in their saliva — a glue that hardens and locks their mouthparts firmly in place while they feed.
Here in Australia, our paralysis tick doesn't use cement at all. Instead, she relies purely on her barbed hypostome to stay anchored — which is exactly why she can still be so hard to remove safely.
Because of this numbing effect, most people don't feel a tick bite until well after it's happened — sometimes not until the tick has already dropped off.
Why This Matters for Disease Risk
Some of the germs ticks carry need time to "wake up" once the tick starts feeding. While the tick stays attached, these germs can multiply inside it and slowly make their way into its saliva glands — the same glands used for feeding.
From there, they can pass into you through the bite.
The simple takeaway: the longer a tick stays attached, the higher the risk of disease. That's why finding and removing ticks quickly — and correctly — really matters.
Why Correct Removal Matters
Now you know what's really going on under the skin: backward-facing barbs, a tick built to stay put, and rising disease risk the longer it's attached.
That's exactly why squeezing, twisting, or yanking a tick out with your fingers can do more harm than good — it can crush the tick, or leave part of its mouthparts behind.
