Cattle tick control

Cattle tick is a serious pest in the Northern Territory (NT). It affects cattle, buffalo, horses, mules, donkeys, sheep, goats, camels, deer, llamas and alpacas.

It can reduce your livestock production and also spread tick fever, which causes sickness and death in affected animals.

Controlling the spread of cattle tick

The NT has a control program which aims to contain ticks to within specific zones, and lower the risk of spreading to areas which aren't yet infected.

It includes measures against the spread of Parkhurst cattle tick, which is a strain resistant to commonly-used chemical treatments.

Interstate and NT stock movements are controlled to limit the risk of ticks spreading.

Parkhurst cattle tick

The Parkhurst cattle tick is resistant to certain chemical products such as Bayticol, Barricade S, Blockade S and Tixafly.

It was first detected on cattle stations in the Darwin region in the late 1990s and has now spread to many properties in the area.

In 2011 a Parkhurst Infected Zone was introduced to contain the Parkhurst cattle tick from Darwin to Pine Creek and east to the boundary of Kakadu National Park.

If you want to move stock out of this zone you must have them inspected and treated. Horses can be moved from the zone to the Cattle Tick Infected Zone without being inspected or treated.

Controls on stock movement

There are different levels of control on stock movement depending on which zone cattle are leaving and where they are going.

The following stock are affected by these controls:

  • cattle
  • buffalo
  • bison
  • banteng
  • horses
  • sheep
  • goats
  • camels
  • deer
  • llamas
  • alpacas.
