Sheep blowfly products

The Elanco blowfly control portfolio includes CLiK™ EXTRACLiK™ and CLiKZiN™ which, as Insect Growth Regulators (IGRs), stop larvae from developing into the harmful second and third stage maggots responsible for fly strike. These are the only products to benefit from FleeceBind™, a technology that allows the product to spread and bind to give full fleece protection*, minimising the risk of fly strike.
The portfolio is completed by the broad spectrum synthetic pyrethroid Crovect™ which treats and controls ectoparasites including blowfly, headfly, maggots, lice and ticks
