    This is my December dewormer every year. Fecal egg counts go down to zero every time (in every horse).

    "Quest plus"

    Have had good results using the Quest Plus in September and Equimax in March. Both were chosen based on personal research and vet recommendation.

    "Horses hate it. We love it!"

    We use this in our rotational de-worming program. The others are apple-flavored, so you can imagine the faces when we use this one!

    "Very good results"

    I use this on my horses in pasture to alternate with Ivermectin Gold from Jeffers with good results.

  5. 5.0 out of 5 stars

    "It's the best"

    I used to think Equimax was best, but have changed my thinking. My crew gets Quest Plus at least once, sometimes twice a year. Equimax or Ivermectin other times

    "Quest Plus"

    I like to use Quest Plus for my spring and fall wormer. Vet recommended and fecal checks prove it to be an effective wormer. Jeffers has a great price and ships promptly.

    "Quest plus"

    Our horses and goats are wormed with Quest or Quest plus and it works great. We have not had any problems with it. It would be nice if the cap were a little easier to remove and re-cap.

    "works great"

    No problems in any of my 4 girls- WB, QH, TB. Just a word of caution that the tube is for 1500lbs, not the usual 1250.

  9. 5.0 out of 5 stars


    Be careful I found that my white horse could not tolerate this combination wormer. He got horrible ulcers. Took a vet visit and more money for ulcer medication to treat the ulcers.

    "I depend on this every year"

    I run a small equine retirement farm, and I depend on Quest Plus for my post-first-frost deworming each year, to help keep my seniors healthy and happy. Jeffers consistently has the best price and quick shipping! Thanks!

    Works great. Fast shipping. Best price on the internet.

    "Very happy with results"

    Even horses that are resistant to other wormers respond to this. We hit all horses and goats if necessary 2x a year with this. Once a year with fen ben and once a year with strongid. Any horse that comes on property is hit with ivermectin upon arrival and manure put in dumpster for 48 to 72 hours. Then at 14 days hit again with Quest or ivermectin. Then go onto seasonal herd worming 4x a year and we have fat, happy ponies and horses

    "quest plus"

    The best winter wormer

  14. 5.0 out of 5 stars

    "Love the applicator."

    This dewormer has a bad reputation due to its extreme effectiveness. As with all dewormers know the weight of your horse and don't give more than recommended. In this case more is NOT better. I really like how the applicator fits in my small hand. The smaller device allows better control when trying to give to the horse who likes to object to oral dewormers.

    "My only option!"

    I have tried everything...with resistant worms as my enemy in TN my goats get regular checks and I use this off label, 1cc / 100 lbs for all my goats. After many losses before, my goats are healthy, happy and worm FREE! Easy administration
