Horse Wormer FAQ’s

What is the most effective wormer for tapeworms in horses?

Praziquantel is commonly considered the most effective treatment for tapeworms in horses. It is often combined with other active ingredients, such as ivermectin or moxidectin, in products designed to target multiple types of parasites.

How often should I deworm my horse?

A deworming schedule should be tailored to the individual horse and its environment. Typically, horses are dewormed every 2-3 months, but this may vary depending on factors such as the horse’s age, climate, and pasture management. Consulting with your veterinarian will help determine the most appropriate schedule for your horse.

Which horse wormers are most suitable for different seasons?

In general, broad-spectrum dewormers are used throughout the year to target common parasites. However, some wormers are more effective against specific types of parasites, which may be more prevalent in certain seasons. For example, ivermectin or moxidectin products are often recommended in the fall and winter, while fenbendazole or pyrantel pamoate may be used in the spring and summer. Again, consult with your veterinarian for specific recommendations.

What are the benefits of using Ivermectin for horse deworming?

Ivermectin is a widely used and effective dewormer. It has a broad-spectrum activity against most common internal parasites, including roundworms, lungworms, and certain types of bots.

Paste, pellets, and liquid wormers are all effective forms of horse deworming products. The choice ultimately depends on the preferences of you and your horse.
