Prevention is better than cure

Zermasect is a pour-on solution that helps with the prevention and control of ectoparasites: Flies, Lice and Ticks.

Flies are not only an annoyance to your flock; they also spread diseases and cost you money. Flies will mass hatch depending on weather conditions, so it is possible to predict an emergence and take action to prevent them.

Flies are common around sheep; they irritate the skin, some feed on a sheep’s blood and may spread diseases. If your flock is under attack from flies act immediately utilising an effective fly-killing product, your RAMA will prescribe the best product for your farm circumstances.

Blowflies are especially problematic, and a bad infestation can be fatal. Adult blowflies lay eggs in sheep wool, which develop into maggots. In less than a week, the population of blowflies is already increased exponentially and an attempt to dampen the population growth is a significant challenge.

If blowflies lay eggs in sheep wool when there is already a wound (common from foot rot, other parasites, shearing cuts or heavily soiled fleeces, etc.) the maggots invade this when they hatch. The larvae then excrete ammonia, which can lead to toxaemia, along with bacterial septicemia, creating a life-threatening condition for the sheep.

Prevention is better than cure

If you wait until fly populations are already established and then try to tackle them, you’re unlikely to win the battle. It’s important to maintain a high level of flock hygiene all year round and form a plan of action in advance.
