EQUINE PARASITES OF FOCUS

Ninety percent of equine internal parasites like small strongyles, tapeworms, pinworms, roundworms, bloodworms and threadworms come from the environment your horse is exposed to every day.1

For adult horses, small strongyles and tapeworms are the key parasites of concern.2 Roundworms continue to be the key parasite of concern in foals.2

Even with no outward signs, parasites can damage vital organs and impact your horse’s health by:

  • Decreasing nutrient absorption
  • Leading to colic or pneumonia
  • Causing irreversible lung damage
  • Impairing performance
  • Stunting growth
  • Causing weight loss
  • Impairing coat condition

Every Horse Needs Individualized Deworming

The most important tool in your parasite control arsenal is your veterinarian. Your veterinarian can perform a fecal egg count (FEC) test to determine which horses in your herd need treatment and which don’t. Once you have a baseline established, your veterinarian can work with you to develop an Individualized Deworming program.

Purchase QUEST and QUEST PLUS from your equine veterinarian or retailer. Prior to purchasing a dewormer, work with your veterinarian to complete a fecal egg count (FEC) test for your horse.


Do not use QUEST Gel or QUEST PLUS Gel in foals less than 6 months of age or in sick, debilitated and underweight horses. Do not use in other animal species, as severe adverse reactions, including fatalities in dogs, may result.
