Over 90% of the small redworm in your horse can be encysted in its gut wall. Undetectable, horses can harbour tens of thousands of encysted small redworm with no visible illness (Love S et al, 1999). Killing these larvae before they emerge en masse and cause potentially fatal intestinal damage is an important part of any worm control programme.

EQUEST is the only wormer to carry on killing small redworm larvae ingested while your horse grazes for a further two weeks after treatment, cleaning the pasture of this parasite and reducing your horse’s exposure to re-infection.

Larvae ingested by your horse as it grazes invade and accumulate in the horse’s gut wall. With warmer and wetter winters the peak periods for larval infestation have expanded resulting in the potential for larvae to be picked up late in the year (Love S, 2003). This accumulation of larvae during the grazing season causes damage and inflammation to the horse’s gut wall resulting in weight loss, as well as having the potential to cause life-threatening illness (Love S et al, 1999).

EQUEST has no confirmed resistance in horses in the UK or Ireland.

EQUEST is kind to the environment. With lower toxicity to dung dwelling insects than ivermectin-based wormers, insects can carry on cleaning the pasture of dung.
