During their life cycle ticks alternate between living on the ground and on host animals, where they feed on the host's blood.
Ticks are most commonly seen in large numbers on livestock during the warmer months of the year. There are several different products available and these should be used once ticks are visible or if animals are rubbing or have large areas of hair loss. All animals in the group should be treated.
For cattle, there are several options for treating ticks. Permoxin can be used as a spray or rinse; Bayticol pour-on provides protection for 3-6 weeks; “Python ear tags” provide protection for at least 6 weeks.
Ticks can be treated with Permoxin insecticidal spray or rinse, to remove any ticks that are present, followed by a repellant collar or tag to prevent re-infection. The wash can be repeated as often as necessary. The collars work well in preventing flies, which makes handling more pleasant.
There is no product licensed for use against ticks in sheep, however there are some off-label options available. Please contact us at the clinic for more information.
Tick control is important during high tick-risk periods. This is commonly mid-August to mid-March, but as long as the mean air temperature is above 7˚C ticks will be active to some degree. Tick control is also important during periods of stress, for example calving and peak milk production.
We recommend Bayticol® as the gold standard tick control product;
- Rain fast within two hours after application
- Controls all life stages of ticks
- Nil withhold period for meat or milk
- Protects for 3-6 weeks
- Available in 1L & 5L
Python® Ear Tags (nb: only an aid to control ticks)
· Aids in control of ticks on cattle
· Two tags, one in each ear
· Aids in control for at least 6 weeks
· Nil milk and meat withhold
These are the only two products licensed in New Zealand for tick control. There are several other products used around the world, many of which are available here and used as part of a routine worm and lice control programme.
Try to identify high risk areas and ear mark them for preserved forage and maize during risk periods. High risk regions would be paddocks with or next to trees, scrub and rough grazing (ie. around drains). Wildlife also poses a risk as small mammals and birds can also act as hosts for ticks.
