Eraquell is a highly effective and safest horse worming treatment. It destroys and controls both immature and adult worms such as roundworms in the stomach and intestines, large strongyles, small strongyles (adults), hairworms, pinworms, ascarids, intestinal threadworms, large-mouth stomach worms, neck threadworms, lungworms, and stomach bots. It contains an active ingredient called Ivermectin. It eliminates various types of internal worms and bots. Eraquell is a highly palatable wormer which is safe to use for horses and the paste treats up to a body weight of 700kgs.
At first I was a bit sceptical about using this paste form my pregnant horse but as mentioned here, it really is safe to use even for a pregnant horse.
Nothing works like this, having used this for first time, Am thrilled to see my stallion running again
I would say it is the fastest treatment we have for worm infection in our horses
