In the January 16 – February 5, 2026 HORSE WHISPERING column we talked about parasites — identifying three specific ones, their life cycles, and what signs your horse might be showing you that may indicate an infestation.
Facts are facts, and it is a fact that parasites are becoming resistance to de-wormers. Literature is actually reporting considerable resistance to wormers like Benzelmin, Panacur, and Antheicide. Surprisingly, there is even resistance to Strongid (pyrantel pamoate) being reported. , The only product that doesn’t have resistance problems in equine parasites is Ivermectin. Is it possible that the ‘cure’ (de-worming) may be weakening our horses (especially if chemicals weaken rather than strengthen our horses)? A recent article in a major equine health magazine stated, “Custom de-worming programs based on consultation of a veterinarian and fecal exams of individual horses will help postpone drug abuse and thus drug resistance by common parasites.” They went on to call it “a looming disaster” if we continue de-worming the way we do today (routinely).
“As needed” de-worming is the answer! The key is to determine WHEN de-worming is needed. The first step is to understand that each horse is an individual – each with individual needs and circumstances. This is a different approach; instead of de-worming by the calendar, it is our responsibility to look at each situation. It’s not difficult, and it may save you some money. Doesn’t that sound good? The answer is SIMPLY check a fecal sample FIRST before you de-worm. All it takes is a thimble full of manure to be checked by your veterinarian. Most usually charge $10 to $15. You may experience a little resistance because they, too, have been exposed to the same myth that “All: horses have worms.” Some entangled in misinformation and myths will try to convince you to worm without checking or will try to sell you a paste wormer. This simple choice to test can lead to healthier horses and, for sure, have fewer resistant parasites in the future. Our horses’ future is in our hands. I invite you to consider checking fecal exams first before you de-worm.
Also, consider the consequences if you de-worm indiscriminately. If the egg count in the fecal manner is 250 or more in the exam, the horse needs to be wormed. If the fecal manner exam is less than 250 egg count, the horse is not in need of worming. Get comfortable with asking questions! A good question to begin with — “Is that preventive measure (especially non-natural) really necessary?” Note: Worms most likely will not be a problem in a dry, hot area; whereas, if the season is warm and moist, you might be more concerned. A really cold winter can be a hidden blessing against some parasites!
In summary: Do a fecal exam, and worm when egg count is 250 or more. If egg count is less than 250, pass on worming that individual horse at this time. Repeat fecal exam every 3 months. The best time to check for effectiveness AFTER de-worming with any product is 2-3 weeks. If you happen to have a horse with a large number of eggs, it should be checked and de-wormed regularly, as needed. New horses entering your farm should ideally be isolated for several days and worm checked prior to putting them into the group.
Two products we have discovered promoting horse health is a paste for creating an environment worms don’t thrive in and another is a supplement you mix with your grain feeding that repels bugs! WORM CHECK is an all-natural combination of several herbs that is proving effective on all species of parasites. It’s an herbal supplement in paste form. It actually works by supporting the horse’s own immune system. We had a situation with a horse where we, under consultation, ended up giving the horse one tube a day for 10 consecutive days. The horse recovered! The other is called BUG CHECK. It’s a supplement you mix with your grain feeding. It repels bugs from the inside out.
May we create a “healthy parasite-zone-free environment” inside and out!
