Within the stomach, parasites become adults in about 8 weeks.

How do you treat small Strongleles?

To treat the small strongyles infection, your vet will also likely prescribe anthelmintics such as:

What Horse Wormer has moxidectin?

EFFECTIVE AGAINST KEY EQUINE PARASITES Small strongyles are the key parasite of concern for adult horses. This equine parasite has shown widespread resistance to fenbendazole. Moxidectin, the active ingredient in QUEST and QUEST PLUS, continues to show efficacy.

How is Habronemiasis treated in horses?

Treatment of the Habronema lesions involves topical and systemic therapies. As the Habronema larvae are found in the wounds and the adult worms are in the horse’s stomach, treatment with anthelmintic agents is recommended. Agents containing Ivermectin are often most effective.
