Parasite Management

Deworming is important to maintaining the health and well being of your horse from foaling to retirement. There are numerous dewormers on the market and they are readily available in various locations from your local veterinary clinic to local hardware store. All present dewormers are orally administered and come in liquid, paste or gel form. Dewormers can vary in their efficacy in eliminating the various parasites, the various stages of the parasite they control and the duration of control they offer. A proper, scientific choice is best made in consultation.  A good plan incorporates judicious use of dewormers to prevent resistance and monitoring of your herd. We recommend:


  • Spring
    • Fecal Egg count - if you have numerous horses the youngest animals are best for screening.
    • Deworming with approved dewormer
  • Summer
    • One to two dewormings two months apart depending on the type of environment your horse is in (barn vs pasture)
  • Fall
    • A deworming in fall is key for bot prevention and MUST be a ivermectin or moxidectin based dewormer (Eqvalan and Quest are two commercially available)
