Apply a single dose with the special "Squeeze 'n' Pour" dispenser pack or the Zoetis Spot On Applicator on one spot on the mid-line of the back at the shoulders as directed on dispenser or applicator gun pack. For blowfly strike on sheep see following specific indication directions.

Lice on cattle

One application will generally eradicate all lice. Complete clearance of all lice may take 4–5 weeks during which time lice hatch from the eggs and are killed. A very few lice may survive on a small minority of animals. Therefore, it may be necessary on rare occasions to re-treat an animal 6 to 8 weeks later.

Flies on cattle

To control biting and non-biting flies, frequency of treatment will depend on numbers and species of flies present. Where horn flies predominate, good control can be expected for 4–8 weeks. Treatment for fly control should not be repeated within four weeks.

Ticks on sheep

Application to the mid-point of the shoulders will provide useful control of ticks attaching to animals of all ages, for up to six weeks after treatment.

Keds and lice on sheep

Application to the mid-point of the shoulders of sheep in short or long fleece will reduce the incidence of a biting lice or ked infestation over a 4–6 week period after treatment.

N.B. For control of ticks, keds and lice on sheep the fleece should be parted and Spot On applied to the skin of the animal.

Established blowfly strike on sheep

Apply directly to the maggot infested area as soon as fly strike is seen. One application will ensure blowfly larvae are killed in a short time. In the case of more advanced strike lesions, clipping out of stained wool before treatment is advisable.

Lice and ticks on lambs

Application to the midpoint of the shoulders will provide useful control of ticks for up to 6 weeks after treatment and will reduce the incidence of biting lice over a 4-6 week period after treatment.

Contra-indications, warnings, etc

Can the cattle /sheep spot on be used on sheepdog?

  • Non-Executive Director

We cannot recommend this product is used on dogs. The active ingredient is sometimes used in other products for dogs, but the dose has to be accurately matched to the weight of the dog. Overdosing can cause toxicity. We would recommend the product Advantix as the nearest equivalent product for dogs. This is safe to use and is particularly good at treating all surface-living parasites on dogs.
