Worming your horse

What wormer should I use for my horse?

Choosing a wormer for your horse will depend on what worms you are trying to treat. There are over 20 different intestinal worms that can be found in horses, the most common worms of concern for the horse population today are, Large Strongyles, Small Strongyles, Roundworms and Tapeworms. You can then choose a wormer that contains the appropriate active ingredients to that treat the worms of concern.

What are the active ingredients in horse wormers?

Horse Wormers will consist of one, or a combination of four different active ingredients (chemicals). The four main chemical groups that are used to treat worms in horses are; 

  • Macrocyclic lactones (mectin based) – broad spectrum protection (not tapeworms)
  • Benzimidazoles – generally used for rotation worming
  • Praziquantel – specifically for tapeworm control
  • Tetrahydropyrimides – narrow spectrum wormer

What is Rotational Worming in horses?

Wormer rotation refers to periodically changing the horse wormer you are using to worm your horse. But it is not about changing the wormer brand but more specifically you must change the active ingredient that you are worming with. The reason you should rotate wormers is because some intestinal worms can build up a resistance to the active ingredient in wormers and therefore their effectiveness can be significantly diminished or become completely ineffective. Popular rotational wormers in Australia include Strategy-Tand AMMO Rotational Wormer Paste (Green).

How often should I worm my horse?

Follow the recommendations on the horse wormer you are using to see when you will need to worm your horse again. Some products have intervals of 6 weeks while others are longer lasting with up to 16 weeks between treatments, like Equest Plus Tape.
