Instructions

Convenient Parasite Treatment

The Quest line offers convenient parasite treatment. Just one dose of Quest Gel (moxidectin) or Quest Plus Gel (moxidectin/praziquantel) treats and controls small strongyles (including encysted forms), large strongyles, bots, pinworms, hairworms, and stomach worms. Quest Plus Gel includes a second ingredient to treat and control tapeworms.

Long-Lasting Parasite Suppression

Twice-a-year treatment for long-lasting parasite suppression with Quest and Quest Plus. Just one dose of Quest in the spring and one dose of Quest Plus in the fall may be the only parasite treatment needed all year long for most horses. The Quest line of products is the only option demonstrated effective against encysted small strongyles and is safe for breeding mares, stallions, and horses six months of age or older.

Why Choose Quest and Quest Plus?

Trust Quest's 25+ year legacy for safe, effective parasite control.

  • The gel formula dissolves quickly on the tongue.
  • The Quest series come in a SURE-DIAL syringe for easy and accurate dosing.
  • In a study, one dose of Quest was nearly twice as effective in reducing small strongyle egg counts as a five-dose treatment of fenbendazole. [1]

Doesn't show any signs of worms?

I can only assume it does the trick. I would have to have a fecal done to be sure for another $35.
