Horse Wormers & Deworming Products

Shop horse wormers and equine deworming products from trusted brands, available in convenient single doses, multipacks, boxes and stud-sized quantities. Our range includes oral pastes, gels, pellets and liquid formulations containing different active ingredients for managing common internal parasites in horses.

Selecting a wormer should be based on the horse’s age, weight, health, management conditions, previous treatments and the parasites likely to be present. Routine interval-based or automatic rotational worming is no longer considered best practice. Faecal egg counts and veterinary advice can help determine whether treatment is required, while follow-up testing can assess whether a product remains effective on your property. This targeted approach helps reduce unnecessary treatment and slow the development of resistance.

Always check the product label for the active ingredients, parasites covered, correct dosage, age restrictions, withholding periods and suitability for pregnant, breeding or young horses. Accurately estimate or measure bodyweight before dosing, and ensure the full calculated quantity is administered.

Effective parasite management also includes removing manure, avoiding overstocking, managing pasture contamination and quarantining new arrivals where appropriate. Seek veterinary guidance when developing a property-specific program or if a horse shows weight loss, diarrhoea, colic, poor condition or suspected treatment failure. Guidance follows the Australian Veterinary Association’s current recommendations.
