We are very pleased to be supporting the "Time it Right" campaign to raise awareness about encysted redworm larvae.

Owners are aware that horses can need treatment for worms and due to growing resistance in recent years to chemicals traditionally used, following active promotion of this fact, more and more owners do use 3-monthly worm counts to decide whether their horse needs treating or not.  This of course is a great step forward but worm counts cannot monitor encysted small redworm, as being larvae and hence immature, there are no eggs. 

Why are encysted small redworms a concern?

The small redworm has the capacity to reproduce in extremely large numbers. Of all the worm burdens found in horses, the highest rate is attributed to this type of worm. What makes these worms even more of a health threat to your horse is that fact that the larvae actually burrow into the gut wall which in itself is damaging, but when the larvae re-emerge in the spring as tiny worms there are literally millions of them and this mass emergence can cause severe digestive upsets such as diarrhoea and colic - and even cost your horse its life!

 Worms counts done in late Spring through to Autumn will of course show up small redworms but not the larvae so even though a worm count may not indicate any issue with small redworms because you have followed a sound targeted worming programme (and by this we mean worming with the correct product when a worm count - including testing for tapeworm - has indicated the need) this does not mean that there will not be some larvae that have successfully made themselves comfortable in your horse's gut wall.

 At present there is no test to detect the offending larvae so it is better to be safe than sorry and treat your horse for the encysted larvae over the winter (an annual treatment is quite sufficient) so as to prevent their Springtime re-emergence as tiny worms. 

There are two options available to you: Either use a wormer which contains MOXIDECTIN such as Equest Praemox or FENBENDAZLE which is available via a 5-day course of Panacur Equine Guard.
