Small redworm are the most common worms found in UK horses today and potentially the most dangerous.
Where do small redworm live and how do they reproduce?
Small redworm live in the horse’s large intestine. As part of the lifecycle small redworm larvae burrow into the wall of the horse’s gut where they develop and emerge to become egg-laying adults and the cycle starts again.
So how can I keep my horse free from these dangerous parasites?
Specific treatment for the encysted small redworm larvae in the winter is vitally important whether or not the horse has symptoms of disease to avoid the risk of larval cyathostominosis. Even if a horse or pony has shown a negative or low FWEC it could still be harbouring several million of these ‘hidden’ larvae and therefore treatment is essential to avoid the risk of this disease.
Which wormer should I use?
The only way to treat for encysted small redworm is by using a product licensed for this parasite. There are only two active ingredients licensed for this purpose: a single dose of moxidectin (EQUEST) or a five-day course of fenbendazole (PANACUR 5 DAY )
