A ready to use topical insecticidal solution containing 12.5 g/l alphacypermethrin.
For the control and treatment of blow fly strike on sheep and lambs, and for the treatment of lice and ticks on sheep. Provides protection against blowfly in sheep and lambs for up to 8 to 10 weeks. Reduces the incidence of headfly strike in sheep and lambs for up to 6 weeks. Provides control of ticks in sheep for 8 to 12 weeks.
Dosage and administration
The product is applied using an adjustable dosing gun fitted with a T-bar, at a rate of 40 ml for animals weighing 25 kg or more, and 25 ml for animals weighing less than 25 kg.
For dosages of 40 and 25 ml apply as two half-doses. Apply the first half-dose evenly along the back line from the neck to the saddle and the second half-dose evenly from the saddle to the tail head and around the rump. For the control of blowfly it is important that there is good coverage around the tail area. The T-bar must be held against the fleece so that the dose is applied directly into it. For treatment of existing strike apply the dose directly to the struck area. Most strikes will require the application of 5 ml (saucer size) or 10 ml (dinner plate size). For the reduction of headfly strike 5 ml per animal is applied between the horns, irrespective of size of the animal.
Blowfly – For the control of blowfly a single application will normally provide 8 to 10 weeks protection. Re-treatment may be necessary after this period. For the treatment of blowfly strike, a single treatment applied to the infected area will ensure blowfly larvae are killed.
Ticks – A single treatment will normally provide control of ticks for 8 to 12 weeks.
Headfly – A single treatment will reduce the incidence for up to 6 weeks.
Lice – A single treatment will normally kill all lice.
SHEEP (>25 kg)

Further information
Alphacypermethrin is a synthetic pyrethroid, which works as an insecticide and repellent by inhibiting neural transmission in insects. Alphacypermethrin is lipophilic and is retained in the wool grease of the sheep fleece to provide protection from blowflies for up to 8 to 10 weeks.
Alphacypermethrin has low toxicity to mammals. There have been no tests of the effects of alphacypermethrin on foetal or lamb development.
The Simcro Tech 25 ml pour-on applicator gun and associated T-bar is recommended as the product may have a detrimental effect on certain parts of conventional dosing guns and this will also ensure correct application and distribution of the product.
