8 Best Horse Wormers: Safeguarding Your Equine Companion’s Health


Maintaining the health and well-being of your horse is a top priority for any equestrian enthusiast. One crucial aspect of equine care is managing and preventing internal parasites, commonly known as worms. These parasites can pose a significant threat to your horse’s health if left unchecked. Fortunately, a variety of horse wormers are available to help you protect your beloved equine friend.

In this article, we will explore the world of horse wormers, discussing the best options to keep your horse healthy and free from internal parasites.

Best Horse Wormers

Horse worms cannot be avoided; they can only be treated with horse wormers, thus regular deworming is required. According to current thinking, it is difficult to completely eradicate all parasites, so you should focus on the ones that are most common and likely to affect your horse and use appropriate horse wormers.

Additionally, every horse is unique and has various needs. The most crucial elements that will decide whether you should deworm your horse every 12 months or every two years, for example, are whether or not your horse lives with others and the climate. The best dewormer for you will be chosen based on these disadvantages.

The majority of wormers are administered to horses by syringing or spraying a gel or liquid into their mouths. If your horse rejects this kind of oral medication, you may also provide pills and certain powdered medications. A dewormer should often be administered straight, rather than being combined with food or drink, to make sure the horse receives the whole amount and none is missed.

Finding the ideal product for your horse may be challenging since there are so many alternatives available from a wide range of reputable manufacturers. To assist, we have put together a buying guide and evaluations of the top eight horse wormers.

Strongyles, pinworms, stomach worms, threadworms, and dermatitis are the conditions that the ivermectin component treats. It is not considered to be useful against tapeworms. The exact parasites that a horse has or is expected to have should be the focus of the owner’s parasite management plan, which should also take into account the horse’s weight, the surrounding environment, and the weather. The worms and bots that might be attacking your horse will be more under control with this regimen.

The apple-flavored paste-gel comes in an accessible syringe with weight gradation along the syringe.

Some orders have been completed with goods whose “best before” dates are just a few months away. As a result, you may not be able to store the remaining packets securely for use in the future. However, the six-pack is useful if you are treating many horses.

It is simpler to use the dose markings on the syringe, which are based on the horse’s weight than to figure it out on your own. The syringe, however, is rather rudimentary, so this may only work on horses who are content to have wormer syringed into their mouths.

Buyer’s Guide

The most prevalent ailments that affect horses are worms and intestinal parasites. They may manifest as colic, weight loss, reduced development in foals, and even breathing issues. Consequently, controlling worms is a crucial aspect of horse ownership.

Additionally, there is a great deal of misunderstanding and several falsehoods in this field. You can discover information about horse worms, how to pick the best wormer, and what characteristics to look for in this guide.

How Do Horses Get Worms?

Horses often get worms. During grazing, they may be picked up from the droppings of other horses and transferred from one horse to the next. As a result, horses who interact with people often or that graze in pastures where other horses are present are more likely to get one of the many different kinds of horse worms and parasites that exist.

Because a pasture may harbor an infection for a long time, pasture cleanliness is one of the most crucial components of a worm control strategy.


The kind of worm or parasite, its intensity, and other circumstances may all affect the symptoms. However, in general, you should watch out for the symptoms listed below and have a worming test done if any are present.

Symptoms of worms to look out for:

• Colic

• Diarrhea

• Damaged coat

• Lethargy

The best ways to test for worms include:

• A fecal egg count, which counts the amount of eggs in your horse’s feces, is one of the finest techniques to check for worms. 

A blood test establishes the presence of and evaluates the levels of certain substances in the blood, expressing the results as eggs per gram (EPG) and the number of worms in your horse’s stomach.  

•   There are specific tests for tapeworms as well, and these chemicals, which are released by parasites, are a certain indication of the presence of worms. One of them is a straightforward saliva test, which is carried out more quickly than a blood test. They are less expensive and more practical since you can carry them out in the stable.

How to Manage Worms

If your horse has been diagnosed with worms—whether it’s via a fecal egg count, blood test, or your own assessment—there are steps you can take to get rid of the parasites and stop them from reappearing the following year.

The best methods for managing worms include: 

The best methods for managing worms include:  Egg counts may be performed every 12 weeks, and a general testing schedule often includes tests every 2 weeks.

• Pasture management: Eggs, larvae, and parasites may live for months in excrement in paddocks. In fact, the larvae may readily be consumed by grazing horses since they pupate in the soil for almost a month before ever becoming adults. Clear up droppings at least twice or three times each week, but preferably every day, to help stop parasites from spreading in this manner. To reduce the possibility of contamination, limit the number of horses you maintain per acre to two at most. You should also spread out the grazing on the pasture by rotating the fields and paddocks throughout the year.

• Regular deworming should be included in your routine. Veterinarians advise deworming every two months and rotating the dewormer used since parasites may become resistant to certain medications and their constituents. Rotation ensures that the parasites won’t develop a resistance to the treatments, keeping each one effective.

When to Worm My Horse?

Although parasites are relatively prevalent in horses, only around one in five are thought to be wormed and need deworming. As a result, testing is just as crucial as worming itself.

Every two months, test your horse. Use the proper dewormer if the result is positive.

Although some medications advise usage only from the age of 8 weeks, foals may often be dewormed as early as 4 weeks of age. Make sure the product you choose is appropriate for the horse’s life stage, particularly if you own a mare who is pregnant or nursing, an older or underweight horse, or a stallion that is used for breeding.


Common Horse Worms and Parasites

Horse worms may take the following main forms:

• Ascarids – Large roundworms are most often detected in young horses, but as your horse gets older, it will get immune to them. They obstruct the horse’s digestive tract, which may result in diarrhea and bad health. The ascarid may also result in respiratory and breathing issues since it develops in the horse’s lungs. For this parasite, ivermectin is regarded as the most efficient form of wormer.

• Bots – These are present on the summer coat, discovered in the stomach during grooming, and ejected in the winter. Typically, they do not cause major sickness.

• Redworms – Redworms are a rising threat that should be taken seriously because they may harm the stomach lining when they emerge from their winter cyst homes in the spring. These are a significant contributor to colic in horses, and numerous kinds of wormers have shown promise in treating them. Fenbendazole and moxetectin are considered suitable wormers in addition to ivermectin.

• Strongyles – Strongyles are year-round pests that may harm artery walls, causing blood clots and tissue death. It is well known that moxidectin and fenbendazole may cure encysted strongyles successfully.

• Tapeworms – Although they might be hard to find, tapeworms are widespread in the fall and can be detected by a blood test. Tapeworms may be treated with praziquantel and moxidectin when taken in the proper quantities.


Horses may be regularly tested to determine the presence and kind of parasites, eggs, and larvae. The best wormer to kill current infections may be selected after the kind of worms present have been recognized. The greatest chance of keeping a horse worm-free is by routine testing, worming, and excellent pasture management.

Horse worms may be treated with a variety of medications, so you should choose one (or a combination of medications) based on the kind of worms your horse has. Use our reviews to decide which wormer is best for you.
