Vectocert – Correct Application is Key.

The Best Advice

Ensure you are ready for action against blowfly strike. The disease is potentially at its worst from June until September-October.

Blowfly Strike poses a serious welfare challenge to animals and can significantly affect farm profitability. More than 80 per cent of sheep flocks are hit by blowfly strike every year.
Figures from AHDB show the total cost to the sheep industry is £2.2 million a year. As well as animal deaths there are losses from damaged wool and fleeces, plus the cost of treatment and strike control.

A Flexible, Efficient Solution

Vectocert offers the benefits of the prevention and treatment of blowfly strike with the added advantage of a short eight day meat withhold. Vectocert can also be used for the treatment and control of headflies and the treatment of ticks and biting lice on sheep.

Offering Excellent Value to Farmers!

A challenge for many farmers is that treating ewes with long-lasting insecticides at the start of the season means much of the product is lost when sheep are sheared, and the treatment of early-season lamb may delay getting them to market.

Basing strike control on a pour-on product such as Vectocert provides more flexible, cost-effective protection for up to eight weeks and it has a withdrawal period for meat and offal of just eight days. There are no restrictions for use during pregnancy or lactation.

Contains 1.25% w/v cypermethrin, POM-VPS. For further information see the SPC, farmers should contact their animal medicines supplier SQP, veterinary surgeon or Downland Marketing Ltd, 15 Victoria Place, Carlisle, CA1 1EW. Use medicines responsibly:
