Regular worming is an important part of keeping horses healthy, but an effective parasite control program is about more than simply sticking to a schedule. Different wormers target different parasites, and one of the most commonly overlooked is the tapeworm.
Unlike many internal parasites, tapeworms rarely cause obvious signs until burdens become significant. They attach to the junction of the small intestine and caecum, where they can interfere with normal gut function and have been associated with certain types of colic. Because infections often go unnoticed, tapeworms can quietly become a problem before owners realise they’re there, making them an important parasite to consider when reviewing your horse’s worming program.
While routine faecal egg counts are an important tool for monitoring many internal parasites, they aren’t considered a reliable way to detect tapeworms. Because tapeworms shed eggs intermittently, horses can carry a tapeworm burden even when a faecal egg count returns a negative result. This means a horse may appear healthy and return a low or negative egg count, while still carrying tapeworms that require targeted treatment.
That’s why many strategic worming programs include targeted tapeworm treatment, rather than relying on faecal egg counts alone. Combining regular monitoring with an understanding of seasonal parasite risks helps ensure your horse receives the right treatment at the right time.
Spring Is the Time to Review
Spring brings new pasture growth, warmer conditions and increased grazing activity, making it an ideal time to review your horse’s parasite management program. As horses spend more time grazing, exposure to pasture-borne parasites naturally increases, making it a good opportunity to ensure your worming program is targeting the parasites most relevant to the season.
It’s also a good time to review the active ingredients in your current worming program. Not all wormers provide the same spectrum of control, so understanding what your chosen product treats is just as important as knowing when to administer it. A seasonal review can help identify any gaps in your parasite management plan before they become a problem.
Not All Wormers Treat Tapeworms
Many horse wormers provide effective control of roundworms, bots and other common internal parasites, but not all contain an active ingredient that controls tapeworms. If tapeworm treatment is required, it’s important to choose a product containing praziquantel, the active ingredient specifically used to treat and control tapeworms.
iO Equigard with Tape combines ivermectin and praziquantel in one easy-to-administer oral paste, providing broad-spectrum control of susceptible roundworms, bots, tapeworms and skin lesions caused by summer sores. By combining both active ingredients in a single treatment, it offers a convenient solution for horse owners wanting broad-spectrum parasite control, including tapeworms, as part of their regular worming program.
As with any parasite control program, treatment should be based on your horse’s individual risk, grazing management and veterinary advice. Selecting the right product helps ensure your worming program is addressing the parasites most likely to affect your horse throughout the year.
The Bottom Line
An effective worming program isn’t just about when you worm, it’s about making sure you’re treating the parasites that matter.
This spring, take the opportunity to review your horse’s worming program and ask one simple question: Does my wormer treat tapeworms?
If the answer is no – or you’re not sure – consider a product containing praziquantel to help ensure this commonly overlooked parasite isn’t left behind. A few minutes spent reviewing your parasite management program today can help support your horse’s health and wellbeing throughout the grazing season.
